What I am asking is what would be a better way to do this. How can I improve my bot so it takes less turns to complete? How can I make my bot 'smarter'?
I think you have too much code in the main method. You should split that into more digestible segments. At least one method for determining the next move, one method for choosing the proper action based on the current tile, etc.. Assuming the gold never moves once it is placed, you could use a Set of all the tiles you have visited.
You could then try to not move to a tile you have already visited. The tiles themselves could be represented as a Point class that contains x and y , or it could be represented as an int if you do a little mathematics to represent a column and row by one single int I do recommend the Point class though.
Or you could make a Tile class, since each tile also has some content wall, exit, gold, empty space You can move in four directions, this is telling me that you should use a Direction enum and replace your four methods with one move Direction4 dir ; By using this enum, you could also simplify your random process:.
This line grabs all the possible directions and randomizes an int from 0 inclusive to length exclusive and grabs the direction with that index. I can assure you, this will never happen. And even if it would, Exceptions are meant to be for Or rather I would have removed the entire line, as it will never happen. Especially when you use the Direction4 approach. The current design does not enforce that bots are playing fair game. A cheating bot could iterate over the whole map myWorld , find the exit point and goes there straight.
The same is true for gold. You should create the mentioned look method which returns only the partial map in 2 blocks away and hide the whole map from the bot. I'd try to create a design where a bot just returns its next action nextAction and the game evaluate actions in a loop and call nextAction again until the bot reaches the exit point. It would help when a dumb bot never finds the exit point. The evaluation logic could kill the bot, no need to duplicate this logic in every bot.
The current code contains a similar thing: counting turns. It could be the game's responsibility to count how many turns have been used to find the exit and how much gold have been picked up. Instead of writing low-level code and handling a bunch of web requests, a library does all of the hard work for you.
To put it simply, libraries package up everything you can do in the Discord API into a nice, clean set of commands. You can then take these commands and create your bot with much less code and much less hassle. We will be using Discord API libraries throughout this guide to make all of this information easier to digest and easier to follow.
And finally, your bot code also on the right. This is the actual code behind your bot that lets it do what it needs to do. Your bot running on your server then interacts with Discord through their API, figures out what events or triggers happened, and reacts in a pre-programmed way.
This is also how you add bots to channels — using OAuth2 requests. Its real power is when you realize you can do all of this without giving out your Discord username and password. This is the beauty of OAuth2. Whenever you get stuck, remember that someone has likely encountered and solved the same problem at least once before. You can browse around GitHub for code examples and some inspiration.
You have an understanding of how Discord bots work behind the scenes, and you know how to get help when you need it. The most important thing is to stick to one single programming language or platform for bot development and master it. Python is a programming language that strives for readable code above all else.
Like we mentioned earlier, you should be using a library whenever possible to avoid writing tedious low-level code around the Discord API. The best library to use for Python is discord. Luckily, discord. To set up discord. That guide walks you through the process of setting up discord.
The discord. You can find the full tutorial to a simple bot over at this link. Pay attention to how they laid out their bot, how they laid out their code, if they have any comments in their code to make reading it easier, etc. If you want to learn how to create Discord bots step by step and dive into more advanced topics, join the WriteBots community. Java is a very popular, stable, and robust programming language that has been around for decades.
I only mention this because when it comes to Discord bots, JavaScript seems to be the most popular language to go with I see it everywhere! This is essentially a software suite that you use to write, debug, and compile all of your code. IntelliJ IDEA has a free, open-source community version that you can download and start using in minutes.
I personally like this IDE since it has a more modern look and feel compared to Eclipse, but this is just my personal preference. You can download Eclipse right now and get going in Java. To simplify your life and start writing your bot as soon as possible, I would strongly recommend getting one of these libraries before starting development. Take a look at this Gradle vs. Maven comparison guide from DZone.
Discord4J is updated much more frequently than JavaCord. If you look at release tags generated by Discord4J and release tags generated by JavaCord over their history, Discord4J is the winner. Discord4J as of the time this guide was written has nearly double the contributors of JavaCord. Here is the contribution chart for Discord4J and the contribution chart for JavaCord.
I personally chose Discord4J since its the most active and more frequently updated of the two, but JavaCord is an awesome choice as well. Link to download JavaCord latest release. To get started with Discord4J, go to this link and start reading through and following along with the setup guide. Once you have Discord4J all configured and ready to go, I recommend following along with this simple bot guide on the wiki.
That guide goes over how Discord4J works subscribing to events, sending messages, etc. If you want to learn even more about Discord bot development and learn even more tips, tricks, methods, and tactics on the subject of bot development, then join the WriteBots community today!
NET framework for quickly getting desktop projects up and running. The first step we need to take is to choose a solid, reputable IDE for our C development environment. Visual Studio and Visual Studio Code there is a difference! NET programming. There are both paid and free versions of VS available depending on use, but you can get the Community edition to start just be sure to read their license limitations in detail. You can download Visual Studio from this link here.
The easiest solution here is to use a cross-platform editor for C development: Visual Studio Code. You can Download Visual Studio Code for free and start coding. NET framework. Your bot will crash! As an alternative download. The other thing I didn't like was that I had to click the button to send a message. That's not how I expect a chat to work.
So I added a click shortcut to the button. Again, basic Vaadin stuff. I was happy with the app, it was a minimal, but complete, chat application that allowed users to interact with bots. However, I'm kind of a go-getter and thought "this would look way cooler with some custom styles and avatars Theming was a lot of fun to do. Especially since it changes the appearance of the app so dramatically.
While I was developing the app, I shared several thoughts and screenshots with my colleague Marcus H. He pointed me to Artur Signell's avataaar component, which looked just perfect for what I needed.
So I went ahead, added the dependency, and modified the code to something like this:. The component creates an avatar from the string. So the app looked like this:. It was good to see those avatars, but the layout… it wasn't that great. If you look at the previous code, you'll notice that I used mostly divs everywhere. The easiest one here is the fromContainer span element. I wanted that to be shown in bold font:. I wanted this to be a row, so that the message was next to the avatar.
Using the browser inspector I edited the MessageList-row selector to set the display property to flex and align-items to center :. I copied this CSS code and put it in the. Finally, I wanted to show the avatar above the name of the person or bot. Once again, using the browser inspector, I edited the MessageList-avatar selector to set the display property to flex , the flex-direction to column and centered the contained items:.
It worked, so I copied the CSS to the project. By using the CSS variables I was sure that if I changed the theme later, things would be in sync with the colors of the theme. So at this point I had this:. Almost there!
The final touch was pretty cool as well, and easy to implement. I wanted the user aligned to the right of the page. Since I was using flex display, I knew I could invert the direction of the layout for the messages from the user. I used the browser inspector to test my idea:.
A one-liner. On the Java side, I just added a flag to indicate whether the message came from the user or not:. Since I was excited to see how Vaadin allows me to do anything with CSS, I went ahead and customized the styles a bit more. I got some help though: The awesome Lumo theme editor. I also added some other tricks that you can explore in the source code on GitHub. Here's the final result:. I figured it'd be a good idea to add multiple bots to the application.
First I searched for ready-made bots online and found some interesting ones.
