Javascript Discord Bot 8 Ball Command

At this point, you should have your development environment ready to go with Node.js and the necessary Discord.js module installed. You should also have your own Discord server, app, and bot user that are ready to be utilized. We should take a moment to make sure everything is set up properly. Let's write the simplest bot possible just to make sure it works.

Let's create a new JS file and write some code to have the bot log in. You can name the file my_bot.js though the file name is not important. Note that by default, a bot has limited permissions.

To perform those admin actions you would need to add the specific permissions to the bot as well as perform additional authentication steps. We are not going to cover that in this tutorial. We will stick with the default permissions like a regular non-admin user. Here are some quick recommendations for the best bots for Discord.

MEE6 bot commands can automatically scan your server's chat for foul language, bad links, spam, and spoilers and warn users of rule violations. You can also use MEE6 to mute, kick, or ban users after a certain number of infractions. MEE6 can also "level up" users on your channel for participation and reward them with custom roles, and search for and play music.

This example will extend the previous example that sends a message to a text channel. Instead of sending a regular text message though, we are going to send an attachment. An attachment can be an image or it can be a file. The attachment can come from your local hard disk or from a web URL. The webAttachment should work as it links to the DevDungeon logo but you can change it to any image or file on the web. The code below will respond any time a message is received with an acknowledgement.

Note that the message event gets triggered even when the bot sends a message. This means the bot could enter an infinite loop where it keeps responds to its own messages. To prevent that, the first thing we are going to do is make sure the message received did not come from our bot itself. If it does, we will just return and take no action.

If the message received comes from another user, it will continue and reply with the acknowledgement message. This code defines a command prefix and a function to return a specific message. Next, replace the existing message event handler with the one below. This code tells the bot to ignore messages from bots and to only respond to messages that begin with the prefix defined above. One of the most unique features of the multi-level communication platform Discord is its bots. You can use Discord bot commands to add music, memes, games, and other content to your server.

//google keywords…Performs a Google search using your keywords//helpShow Beldum-Bot's list of commandsYou're reading it right now! //iconShow the server icon in full resolution//infoShow Beldum-Bot's infoAll the info you can get is on this page! //pingShow Beldum-Bot's ping //reportShow a user how to report a bug if they find one. Changing the bot's activity is relatively simple. We just need to call setActivity() on the bot's user object.

By default it will say "Playing ____" but you can also change the verb to "Streaming", "Listening", or "Watching". After running the code, look at the bot in the member list of the server and you should see it's status change. In the previous example we saw how to get a list of servers the client has access to. The guild object has a property named channels that we can access.

That will give us the list of channels for that specific guild. Another option is to get channels property from the client object instead of the guild object. If we use client.channels as opposed to guild.channels then we will get the list of all channels from all servers. The final thing to do in the developer portal is create an invite link so we can add the bot to a server for testing. Click the OAuth2 setting on the left of the page.

This menu is used to craft an invite link with just the specific permissions that your bot needs. In the new bot permissions menu that appears below, select View Channels and Send Messages. I typed npm install, then filled up the config.json and typed node index.js but this error appeard. Hey everyone 👋🏻, today we are going to make a discord bot 🤖 which will send gifs according to the user in just 30 lines of code!

The way this bot will work is, if you write .gif happy then the bot will se... To add bots to Discord, find it either on an online bot list like top.gg or through the creator's website. After clicking on the bot you want, click the "invite" button to be redirected to Discord's browser application.

After authorizing access, the bot will appear on your server and will be usable right away. If you want to spice your server up with some fun Discord game bots, we recommend IdleRPG or RockPuppy. IdleRPG is a complex roleplaying game bot that lets you create a character, go on adventures, and level up alongside other server members.

RockPuppy adds basic games to the server such as ConnectFour, Truth or Dare, Tarot, and an 8ball. Both game bots provide fun ways to get members more involved in your server by facilitating interactions through text-based games. The bot will generate a random number and select a response based on the number chosen. To keep a bot online all the time, you will need to leave the program running.

You can do this by simply leaving your computer on and never turning it off. An alternative is to rent a cheap $5/month server from a provider like Linode or Digital Ocean. They provide cheap linux servers that run all the time in their datacenter. Another alternative is to use a Raspberry Pi from your house that you leave running all the time. If you want to set up the bot as a systemd service in Linux, check out the creating systemd service files tutorial. To test the code below, run the bot and using your own Discord user send a message to a text channel on your server that the bot has access to.

You can also send the bot a direct/private message and it will respond in the same channel. Once your bot is connected, the client object keep a list of servers it is connected to. In Discord terminology, it is called a guild. The client object has an property named guilds which we can access through client.guilds.

In the following example, we iterate through the list of servers and print out the name of each one. Most likely your bot is only connected to just one server, your test server. Bots can be connected to many servers at once though. After creating app, you need to take one further step and add a bot user to the app. On the app details page, scroll down to the section named bot, and create a bot user.

Save the token, you will need it later to run the bot. If you get an error saying "Too many users have this username, please try another" then you need to rename your application to something more unique. Deathmatch Challenges the user to a randomly chosen trial and sends a direct message notifying them. To use this command, you should also install the ? Roulette command in the Mini-Games section.

I've made it so the command is "!8ball", the bot will answer with "Please ask a full question!" which is meant to happen. But also thinks it's own message is a question and answers it with the 8ball function. Xiao is a Discord bot coded in JavaScript with discord.js using the Commando command framework. With over 500 commands, she is one of the most feature-rich bots out there. Xiao is a Discord bot coded in JavaScript withdiscord.js using theCommando command framework.

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of discord.py 8ball command but without bot prefix without wasting too much if your time. // This command removes all messages from all users in the channel, up to 100. With over 300 commands, she is one of the most feature-rich bots out there.

This assumes you already have a bot account ready to go. Every bot has a series of chat commands you can use in-server to get it to perform certain tasks. Some bots will display a tutorial in-server with these commands once added, while others can be looked up online on the bot's website. To use a Discord bot command, simply type it into the text box on a text channel and press "enter". The bot will prompt you for any follow-up Discord commands. See the GIF above for a quick example of how to use the "status" command on the IdleRPG bot.

Now that we have the latest code on the Pi (refresher here if you're using your own repo), let's edit the config.json file to add the command prefix we want to use. Let's extend the previous example even further by only responding to messages if the bot user was tagged. We will have to inspect the message content and see if our bot's tag was mentioned. We do this by converting our bot's user to a string, and then seeing if the message includes that string.

As you can see, there isn't much to it really. All we do is give the answers in an array and then use a random function to give a number that's between 0 and the number of elements in the answers array. We do however use the await feature and thus, we have to make sure this code is run in an async function. REPORT_CHANNEL_ID is the ID of the Discord channel you want to send messages from report to. Not required, and if not provided the report command simply DMs the owner.

I have nodemon installed on my development PC – it's quick and simple to use. If it detects any altered files, it'll restart the bot. Here we simply launch the bot and take note of any errors. Learning how to make bots on Discord is more complicated than learning how to add a bot to Discord and requires basic computer programming knowledge. As such, be sure to check to see if another application will perform the functions that you are looking for before you make a new bot. By default, the bot supports both message and slash commands.

Type @AsterieBot#7609 help to view the full command list, or simply type / to view the list of slash commands. Now that we're wired up to use dependency injection, and have our service created to handle commands, let's create our first set of commands (the right way!). 8ball command that returns random Yes, No, or Maybe responses.

A common task with Discord bots is to create "commands". A command in this sense is a message that triggers a special action. Commands are often specified by beginning a message with a special character. The output should say Connected as [your bot's name]. If you check the server's member list, the bot should appear online as well. If you can see the bot online in the server, then everything is working properly and we can move on to making the bot actually do something fun!

It is normal for your bot to still appear online for a few minutes after the program is terminated. After a few minutes it will appear offline again. After you have registered your app and created the bot user for your app, you are ready to invite the bot to your server.

To do this, you will need the Client ID for your app. You can get this from your app's "General Information" page. Attach Files is required to allow commands that send files to work. Embed Links is required to allow commands that send embeds to work. The discord bot will constantly be uploading and download data, which will slow your internet speed a little. Recently, many users have reported massive random FPS drops while playing games and streaming them in Discord.

This is the case even with high-end PCs and rules out the possibility that FPS drop is due to low-end PCs and graphics hardware. Bot.login(email, pass / token); (delete whichever one doesn't apply to you) and you're set. If you've already got some node modules installed you should go ahead and delete the folder in order to start fresh.

Starting fresh will help solve a lot of conflict errors we would normally deal with as we go. For the rest of the coding, you can begin by using an application such as Node or Pylon . These applications will run your program after you write it using JavaScript. You can also find thousands of examples of code on GitHub if you search "Discord bots".

How To Find The Volume Of A Gas Collected Over Water

When a reaction produces a gas that is collected above water, the trapped gas is a mixture of the gas produced by the reaction and water vapor. Water evaporates and there is always gaseous water above a sample of liquid water. As a gas is collected over water, it becomes saturated with water vapor and the total pressure of the mixture equals the partial pressure of the gas plus the partial pressure of the water vapor. The pressure of the pure gas is therefore equal to the total pressure minus the pressure of the water vapor—this is referred to as the "dry" gas pressure, that is, the pressure of the gas only, without water vapor. The ideal gas law can be used to derive a number of convenient equations relating directly measured quantities to properties of interest for gaseous substances and mixtures.

Appropriate rearrangement of the ideal gas equation may be made to permit the calculation of gas densities and molar masses. Dalton's law of partial pressures may be used to relate measured gas pressures for gaseous mixtures to their compositions. Avogadro's law may be used in stoichiometric computations for chemical reactions involving gaseous reactants or products.

Apply an approximate correction factor using Dalton's Law, which states that the sum of the individual partial pressures of the gases in a mixture (P1…Pn) is equal to the total pressure . Estimate the amount of water vapor in the hydrogen at other temperatures by using the partial pressure of water vapor at the temperature in question. A sample of hydrogen gas was collected over water at 60°C. If the total volume of gas collected was 80.9 mL and the atmospheric pressure was 1.03 bar, what mass of hydrogen gas was collected above the water? Dalton's law of partial pressure has a practical application in calculating volumes of gases collected over water.

This is a common way of collecting a not very soluble gas, for example, oxygen that has been prepared in the laboratory. The oxygen gas collected in this was is not pure because water vapour is also present in the same space. The total gas pressure is equal to the sum of the pressure exerted by the oxygen gas and the water vapour, which can be measured with a barometer. There is a growing research interest in the development of portable systems which can deliver hydrogen on-demand to proton exchange membrane hydrogen fuel cells. Researchers seeking to develop such systems require a method of measuring the generated hydrogen.

Herein, we describe a simple, low-cost, and robust method to measure the hydrogen generated from the reaction of solids with aqueous solutions. The reactions are conducted in a conventional one-necked round-bottomed flask placed in a temperature controlled water bath. The hydrogen generated from the reaction in the flask is channeled through tubing into a water-filled inverted measuring cylinder. The water displaced from the measuring cylinder by the incoming gas is diverted into a beaker on a balance. The balance is connected to a computer, and the change in the mass reading of the balance over time is recorded using data collection and spreadsheet software programs. The data can then be approximately corrected for water vapor using the method described herein, and parameters such as the total hydrogen yield, the hydrogen generation rate, and the induction period can also be deduced.

The size of the measuring cylinder and the resolution of the balance can be changed to adapt the setup to different hydrogen volumes and flow rates. The laboratory methods specified for this procedure are based on American Standards and Testing Materials , US Environmental Protection Agency , and Gas Processor Association methods. These laboratory methods measure the volume and composition of gases that flash from the liquids, including a Gas-Oil or Gas-Water Ratio, as well as the molecular weight and weight percent of the gaseous compounds.

Included are procedures for measuring the bubble point pressure and conducting a laboratory flash analysis. The laboratory results are used with the crude oil or condensate or produced water throughput to calculate the mass of emissions that are flashed from the liquids per year. Step 6 _ The molar volume of all gasses at STP is supposed to be the same.

It is known and you would not need to determine it experimentally. If as a lab exercise you are supposed to determine it from the data of this experiment, you would take the volume, and number of moles and calculate the volume per mol. Then, using the temperature and partial pressure of hydrogen measured/calculated, correct that volume to STP conditions.

It should come close to the known molar volume of all gasses at STP. If not, the difference is experimental error, calculation error, or some flaw in the reasoning (maybe even the assuming that the gas collected is also at 23.2 degrees). In the tube, a mix of hydrogen gas and vapor water will collect.

For starters, I would assume that the temperature of the gas and everything else has equalized, and the entire lab is at 23.2 degrees. If that was not the intention of the author of the problem, we should find out when numbers do not agree. You had a long tube filled with water inverted over a container with water. The tube ended with water to a level 460.0 mm higher than the level of the water in the outside container.

The water level difference indicates a pressure difference. Maybe you can find a conversion factor between mm water and torr. Otherwise, you would know that a 13.6 mm column of water exerts the same pressure than a 1.0 mm column of mercury because the density of mercury is 13.6 times the density of water. You will begin by reacting a known mass of magnesium metal with an excess of hydrochloric acid. The hydrogen gas produced will be collected by displacing water in a gas collection tube. Whenever a gas is collected over water, the result is a mixture of the collected gas and water vapor.

Eventually, these individual laws were combined into a single equation—the ideal gas law—that relates gas quantities for gases and is quite accurate for low pressures and moderate temperatures. We will consider the key developments in individual relationships , then put them together in the ideal gas law. The partial pressure of water vapour above liquid water is called its vapour pressure, which depends on the temperature. At room temperature the vapour pressure of water is only about 20 Torr. The following shows that we can use Dalton's law to calculate the amount of gas collected over water.

Many chemistry and physics experiments involve collecting the gas produced by a chemical reaction and measuring its volume. Water displacement represents one of the easier methods to accomplish this task. The technique typically involves filling a glass column open on one end with water and then inverting the column and submerging the open end in a bowl of water. Columns built specifically for this purpose are called eudiometer tubes. The determined volume of a gas becomes useful only if the pressure of the gas is also known.

This requires equilibration of the pressure inside the tube with atmospheric pressure. Oxygen gas is collected over water at a temperaturee of 10 degrees C and a pressure 1.2 atm. The volume of gas plus water vapor collected is 293ml.

Q. The hydrogen gas formed in a chemical reaction is collected over water at 30.0 °C at a total pressure of 732 mmHg. This procedure is used to determine the bubble point pressure at sample collection temperature of a pressurized hydrocarbon liquid prior to conducting a flash or any compositional analysis. These results determine the integrity of the sample and provide a means of verifying the sampling conditions reported on Form 1. When heating is required, safety precautions must be taken due to thermal expansion within a pressurized cylinder. This procedure is performed with the use of a Double Valve cylinder and is not applicable for Floating-Piston cylinders.

Samples gathered with the use of a Floating-Piston cylinder must be transferred to a Double Valve cylinder using a water displacement method prior to conducting this procedure. This procedure is used for determining the annual flash emission rate from tanks used to separate, store, or hold crude oil, condensate, or produced water. The laboratory methods required to conduct this procedure are used to measure methane and other gaseous compounds. Consider gas which has been collected over water to be saturated with water vapor. During the collection process, the water level in the measuring cylinder adjusts to maintain the internal pressure in the measuring cylinder at atmospheric pressure. Rather than being manually recorded, the data is logged in a spreadsheet using a data collection software package which allows the balance to send data to the computer.

A sample of hydrogen gas is collected over water at 25 c. Volume of sample pressure of sample vapor pressure of h;0 (25°c) 82. A gas produced in a chemical reaction can be collected by water displacement. Because the gas is collected over water, it is not pure but is mixed with vapor from the evaporation of the water. Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor.

The ideal gas law describes the relationship between the pressure, volume, temperature, and number of moles of an ideal gas. Discover the ideal gas law equation and explore sample problems and solutions involving the ideal gas law. We have previously measured quantities of reactants and products using masses for solids and volumes in conjunction with the molarity for solutions; now we can also use gas volumes to indicate quantities. If we know the volume, pressure, and temperature of a gas, we can use the ideal gas equation to calculate how many moles of the gas are present. If we know how many moles of a gas are involved, we can calculate the volume of a gas at any temperature and pressure. This procedure is conducted by collecting samples of crude oil or condensate and produced water upstream of a separator or tank where flashing may occur.

Samples must be collected under pressure and according to the methods specified in this procedure. If a pressure separator is not available for collecting samples, sampling shall be conducted using a portable pressurized separator. A sample of hydrogen gas is collected over water at 25 C.

Volume of Sample Pressure of Sample Vapor Pressure of H;0 (25°C) 82.33mL 745mmHg 23.8mmHg Determine the mass and root mean square velocity of the hydrogen gas collected. We can calculate the number of moles using the ideal gas law once we know the partial pressure, the volume and the temperature. The thin skin of our atmosphere keeps the earth from being an ice planet and makes it habitable. In fact, this is due to less than 0.5% of the air molecules.

Of the energy from the sun that reaches the earth, almost \frac[/latex] is reflected back into space, with the rest absorbed by the atmosphere and the surface of the earth. Some of the energy that the earth absorbs is re-emitted as infrared radiation, a portion of which passes back out through the atmosphere into space. However, most of this IR radiation is absorbed by certain substances in the atmosphere, known as greenhouse gases, which re-emit this energy in all directions, trapping some of the heat. This maintains favorable living conditions—without atmosphere, the average global average temperature of 14 °C (57 °F) would be about –19 °C (–2 °F). The major greenhouse gases are water vapor, carbon dioxide, methane, and ozone. Since the Industrial Revolution, human activity has been increasing the concentrations of GHGs, which have changed the energy balance and are significantly altering the earth's climate .

6 Nitrogen gas is collected over water in a measuring cylinder, the level of water being the same inside and outside the cylinder. The volume of nitrogen collected was 120 mL, the temperature was read as 21 oC. Calculate the volume of dry nitrogen obtained at 298 K and 101.3 kPa.

To investigate the reproducibility of the experimental set-up, varying masses of silicon were reacted with aqueous sodium hydroxide solutions to generate hydrogen. The average hydrogen generation curves are shown in Figure 1. Average total hydrogen yields, hydrogen generation rates, and induction periods for each mass of silicon were also calculated and are plotted with error bars representing one standard deviation in Figures 2, 3, and 4, respectively. There was very little deviation in the total hydrogen yields and hydrogen generation rates between reactions, and a greater level of deviation in the induction periods. Oxygen gas generated in the decomposition of potassium chloride and collected over water at 20oC. The volume of the gas collected at atmospheric press 755 Torr is 370mL.

The pressure of the water vapour at 20oC is 17.5 Torr. A gas is collected over water at 30.0 degrees celsius. Water vapor pressure at twenty degrees Celsius is 27.5 mm Hg. The properties of N2 will deviate more from ideality at -100oC than at 100oC. Van der Waal's equation corrects for the non-ideality of real gases. Molecules of CH4 at high pressures and low temperatures have no attractive forces between each other.

Molecules of an ideal gas are assumed to have no significant volume. By automatically logging the data in a spreadsheet, this method offers a significant improvement in accuracy and temporal resolution with respect to water displacement methods which rely on recording the volume of gas evolved manually. 1.00g of air consists of approximately 0.76g of nitrogen and 0.24g of oxygen. Calculate the partial pressures and the total pressure when this sample occupies a 1.00L vessel at 20oC. So, for your question water vapor and the gas occupy the same volume. What is different is the partial pressure and the number of moles of each one.

The important thing to remember about gases that are being collected over water is that the total pressure measured includes the vapor pressure of water at that given temperature. In order to solve a problem, it is necessary to know the vapor pressure of water at the temperature of the reaction . The sample problem illustrates the use of Dalton's law when a gas is collected over water. The volume of gas collected and the gas laws can be used to calculate the number of moles of gas collected.

The partial pressure of a gas in a mixture is the pressure it would exert if it alone occupied the container. If we have gas A and B in a container, then partial pressures of A and B are expressed as PA, PB. Dalton then described the behaviour of gases mixture by his 'law of partial pressure'. Lower the eudiometer into the water-filled graduated cylinder prepared in step 1 until the water level inside the eudiometer tube is exactly even with the water level in the graduated cylinder. At this point, the pressure inside the eudiometer tube is equal to the pressure outside the tube, i.e., atmospheric pressure.

Now read the volume of the water level in the eudiometer tube. Because glassware manufacturers label the volume readings on eudiometer tubes from closed end to open end, this volume reading will reflect the volume of gas in the tube. An ideal gas is a hypothetical construct that may be used along with kinetic molecular theory to effectively explain the gas laws as will be described in a later module of this chapter.

Although all the calculations presented in this module assume ideal behavior, this assumption is only reasonable for gases under conditions of relatively low pressure and high temperature. In the final module of this chapter, a modified gas law will be introduced that accounts for the non-ideal behavior observed for many gases at relatively high pressures and low temperatures. Now you know how to calculate partial pressure using the ideal gas law. Let's move on to the last two forms of the partial pressure equation - both using Henry's law. Imagine that you need to do a lab experiment where hydrogen gas is generated.

In order to calculate the yield of gas, you have to know the pressure inside the tube where the gas is collected. All you need is the atmospheric pressure in the room. As the gas pushes out the water, it is pushing against the atmosphere, so the pressure inside is equal to the pressure outside. The pressure inside the bottle is partially from the gas being collected and partially from the water vapor that has escaped from the surface of the water in the jar. The water inside the jar will reach an equlibruim state where the number of molecules leaving the surface is the same as the number returning.
