Robocode Tank Royale

Build the best - destroy the rest!

About

Robocode is a programming game where the goal is to code a bot in the form of a virtual tank to compete against other bots in a virtual battle arena.

The player is the programmer of a bot, who will have no direct influence on the game him/herself. Instead, the player must write a program with the logic for the brain of the bot. The program contains instructions to the bot about how it should move, scan for opponent bots, fire its gun, and how it should react to various events occurring during a battle.

The name Robocode is short for "Robot code," which originates from the original/first version of the game. Robocode Tank Royale is the next evolution/version of the game, where bots can participate via the Internet/network. All bots run over a web socket.

The game aims to help you learn how to program and improve your programming skills, and have fun while doing it. Robocode is also useful when studying or improving machine learning in a fast-running real-time game.

Robocode's battles take place on a "battlefield," where bots fight it out until only one is left, like a Battle Royale game. Hence the name Tank Royale.

Note that Robocode contains no gore, blood, people, and politics. The battles are simply for the excitement of the competition we appreciate so much.

Please head over to My First Bot tutorial to learn how to set up your first bot for Robocode Tank Royale.

Supported platforms

The Robocode game itself needs Java 11 or newer and can run on these operating systems:

• Windows
• macOS
• Linux

These platforms are currently supported out of the box:

• Java
• .Net

Bots can (in theory) be written for any platform and programming language, as long as they have access to a WebSocket API, and also follow the protocol needed for communicating with the server.

However, these Bot APIs are provided that take care of all the communication with the server in the background, so you only need to deal with the bot logic:

• Bot API for the Java (JVM) platform
• Bot API for the .Net platform

Both implementations are first-class citizens within Tank Royale, and more might follow in the future for other popular platforms. Also, note that sample bots are provided for both APIs.

Supported programming languages

Due to the current bot APIs for the JVM and .Net, Robocode (should be) able to support these programming languages with the current Bot APIs:

• Java (JVM) platform: These (and more) programming languages are available:

  • Java, Groovy, Kotlin, Scala, Jython, and Clojure

• .Net platform: These programming languages (and more) are available:

  • C#, F#, Visual Basic, and IronPython

tank-royale's Issues

Bots in Bot Directories can't join the battle

Describe the bug
when you want to start a battle, you may choose bots are in bot directories, but you only can choose from joined bots(i dont know what is this means). but you can start bots local (i dont know what is this).

BulletHitBotEvent vs HitByBulletEvent

Describe the bug
Bot API allows to use onHitByBullet​(HitByBulletEvent hitByBulletEvent)
But the bot receives the BulletHitBotEvent instead:

{"victimId":1,"bullet":{"bulletId":10,"ownerId":3,"power":2.0,"x":388.9596630220835,"y":582.0,"direction":0.0,"color":"#008000"},"damage":10.0,"energy":42.59999999999999,"turnNumber":167,"type":"BulletHitBotEvent"}

Expected behavior
Expecting to receive as bot a HitByBulletEvent
Leave the BulletHitBotEvent for Controllers and Observers

Additional context
YAML of the 2 events for easy comparison of the contents
bullet-hit-bot-event
hit-by-bullet-event

getTurnRemaining is broken with the bot API 0.13.3 for the Java version

Describe the bug
The sample bot, Corners, provided with the sample bots does not turn correctly anymore.
The issue is with the getTurnRemaining() method, which does not return the correct value.

To Reproduce
Steps to reproduce the behavior:

• Start a battle with the Corners Java sample bot from release 0.13.3.
• Observe that Crazy moves on a line without turning. It should turn when moving forward and back.

at each tick the bots receives the full list of bullets

Describe the bug
As far as I know the bullets of other bots should be invisible to the bot but right now at each tick, inside the
tick-event-for-bot there are the bullets of other bots too

To Reproduce
I'm seeing this because I'm develping a full botApi in a different language so I can't explain step by step, if you read any tick-event-for-bot while any bullet is on the field you will see that those bullets are included in the bulletStates

Expected behavior
the bulletStates inside the tick-event-for-bot must contain only the bullets owned by the bot that shoot them

Print out
example of 2 consecutive ticks I've captured

TICK T
(bulletId: 3, ownerId: 1, power: 1.0, x: 249.4709461593531, y: 344.0048802302621, direction: 148.5360218511403, color: "")
my id is 2

TICK T+1
(bulletId: 3, ownerId: 1, power: 1.0, x: 234.9704818187843, y: 352.8782411441377, direction: 148.5360218511403, color: "")
my id is 2

Robocode Server version
Robocode Tank Royale Server 0.17.4

Server is not accepting the full range of ports

Describe the bug
The range ports for a standard computer is 1-65535 but the server uses a Short to store the port so the port can't have a port over the maximum positive short, that is 32767, leaving out 65535-32767=32768 unusable ports

To Reproduce
FAIL
launch the server with the maximum short+1=32768 and it will fail wiht the message "Invalid value for option '--port': '32768' is not a short"
java -jar robocode-tankroyale-server-0.19.1.jar --botSecrets veuogdpgjtd --controllerSecrets ifrafjbrpcg --port 32768

NO FAIL
launch the server with the maximum short = 32767 and the server will start ok
java -jar robocode-tankroyale-server-0.19.1.jar --botSecrets veuogdpgjtd --controllerSecrets ifrafjbrpcg --port 32767

Expected behavior
The server should be able to use any port out of the full range

Screenshots

Round ended event for bot is not sent

Describe the bug
The new round ended event for bot is never received by my bot. I believe that even the no-more "round ended event" was never sent to bots.

Expected behavior
at the end of each round a round ended event for bot is received by the bot

GUI: Unreadable Server Log on NixOS

Describe the bug
Dunno if this is only on my machine but when I open the server logs in the GUI I see white characters on a light grey background, making the all logs not readable if not highlighted or copied somewhere else.

To Reproduce
open the GUI, run a server and open "Show Server Log"

Additional context
I want emphasize that this could be really caused by my desktop. I don't even want to push on this, I don't really need to se these logs right now.

Blocking functions `forward` and `back` do not execute on first run

My run function looks like this:

@Override
public void run() {
    forward(500);
}

When I create a battle and boot my robot, in the first battle, the robot does not move forward. Restarting the battle does not replicate the error. Stopping the battle and starting a new battle without unbooting and rebooting the robot does not replicate the error. However, stopping the battle, starting a new battle, unbooting the robot, and booting it again does replicate the error.

This behavior does not occur for blocking functions turnRight and turnLeft

Video demonstrating the issue:

TickEventForObserver and TickEventForBot seem not containing real values

Describe the bug
I have the suspect that the "botState" in both TickEventForBot and TickEventForBot is reporting only the starting values for the bot but for some elements.
For example:
energy is updated
direction is not updated

Is a suspect, because I'm observing this using my API that I'm developing, but if I run the bot with the GUI i can see it moving and doing actions, but from the printed RAW ticks the botState is not changing.

To Reproduce
TickEventForObserver
one need to implement an observer and watch the TicketEventForObserver messages

TickEventForBot
build an API and observe the raw ticks from the server during a match. :P

Error info
Here RAW messages of a TickEventForBot and TickEventForObserver of the turn 38

the server was started with initial positions enabled and with this positions:
test bot x:400,y:300,angle:0
another bot x:0,y:0,angle:90

and the ONLY instruction given was for the test bot to turn right by ~176 degrees (random value) starting at turn 10 and completed at turn 37 (expected behavior)

Additional context
About the TickEventforObserver:
This problem is affecting only who is working with a Controller. So me that I'm developing an API for the bots, and i use a Controller to do automated tests, and I'm using the BotState to check what the bot is doing. For the majority of the people, the Controller is hidden in the GUI and are not affected by this issue.

About the TickEventForBot, every creator of a bot should be able to observe this

booted bots can't join the battle

1. I started robocode-tankroyale-gui-0.22.0.jar on Windows 10.
2. Selected Config Menu -> "Bot Root Directory" and added the path to the sample bots
3. Selected Server Menu -> Start Server
4. Selected Server Menu -> Select Server -> Test -> "server is running"
5. Selected Battle Menu -> Start Battle -> Selected some bots from "Bot Directories (local only)" and clicked on Boot-Button.
6. Selected Bots were shown on "Booted Bots (local only)" list
7. "Joined Bots (local/remote)" list stays empty. So I can't add a bot to "Selected Bots(local/remote)" list and the "Start Battle" Button remains disabled.

What wents wrong?

@SirStone
I can't say if I noticed this after the updates or was already present before. Looks like the bug affecting the logs and others components is affecting the popups.

Bots receives skipped-turn-event events while dead

Describe the bug
I've took a while to discover this because I actively started again to work on code only yesterday, but looks like to me that at the death of the robot the server is still giving out the "skipped-turn-event" every turn

Expected behavior
2. stopping receiving the "skipped-turn-event" if the bot is dead

Screenshots

Add stepping turn-by-turn if battle is paused

When debugging a bot, it is helpful to observe what it does one turn at a time. The game already implements pausing a battle, which helps a lot. This could be expanded on by allowing paused matches to progress by one turn per hotkey/button press.

Getting results at round end

Is your feature request related to a problem? Please describe.
At the moment the results are provided at the end of the battle, I think that would be very useful to have the (partial) results provided at the end of each round

WebAssembly build

Hi, thanks for sharing this cool project.
It would be cool if we have a webassembly version of robocode so that people can watch a robocode game session in a browser. :D

I could offer some help on that. I guess this should be relatively easy, since we just need to fetch the game state and render it as is.
I could implement it either in Rust or C++ with sdl.

Let me know what you think. :D

Game replays

Describe the solution you'd like
Curious if there's any way to record / replay games from the server side?

Describe alternatives you've considered
Right now I have a semblance of recording via some custom python rendering in bot PoV. Would be cool to see it from the server side though.

Add a bot log console

When developing a bot, want to check certain values during runtime. I added some print statements to my bot's code, but when running the bot, I don't know if there is a console or similar for catching and displaying these print statements. If this feature does not exist, it would help the debugging experience. If there is currently a method to read bot print statements, please let me know.

Possibility to identify bot from Process to Tick

Is your feature request related to a problem? Please describe.
As I described in this discussion I'm developing an alternative graphic client for roboocode Tankroyale, focused on my needs.
The application runs the bots, the server and the controller. My problem is to match the runned robots from process with the bots competing into the battlefield but with the situation nowday looks like is impossiible with 100% accuracy. Here's why:
The bot is identified in 3 different ways not linkable to each other if not with guesses.

1. The bot process is identified by the PID
2. the bot (from version 0.17.0 of the libraries) is receiving a unique session id, aka sessionId, from the server and is shared to the controller via the BotListUpdate message
3. the bots, during a battle, is identified by an Id, given with the TickEventForObserver message
   Assuming that my web application can correctly come in possession of all PIDs, Session IDs and in-battle IDs, right now it hasn't the possibility to connect the bots in these three lists together.

If not clear enough I've put, at the end of the request, a simulated example of situation where the matching is impossible.

Describe the solution you'd like
I think that the simpler and easier solution (and so the best) is to add to the BotListUpdate message, as middlepoint between the new bot and the battle, two fields: the PID of the bot (given by the bot itself during the handshake) and the id of the battle, pre-issued by the server that will later use as ids for the battle.
In this way the botlistupdate bot object would contain: name, sid, host, port, pid, battle id. With this combination of data every program will be able to discern what a bot is doing in every level of the software without confusion.

ps: I approve the usage of short ID for the battle, means less data to transfer for every tick and the ticks are spammed like hell during the battle, keeping those smallest as possible is mandatory.

Describe alternatives you've considered
Alternatives I like less

1. the bot process, same way as the booter, is capable of receiving input from stdinput and answer to the command "identify" with "PID, sessionID, battleID"
2. BotUpdateList adds the PID and TicksUpdateEventForObserver uses the sessionid instead of the "battle id"
3. possiblity to enable for the bot "route stdout to websocket" that set the bot to route the stdoud and stderr messages to a websocket where any software can connect to and listen what the bot process says and TicksUpdateEventForObserver uses the sessionid instead of the "battle id". This solution should disable the need to use the PID and realy on the booter application to boot the bots.
4. any combination of the above solution should solve the main issue

Additional context
simulated example, where the data has the same content is written in italic:

1. I want to run 3 times the same bot pippo and i get from this 3 bot processes with possible identification by name and/or pid:

• (pippo,pid1)
• (pippo, pid2)
• (pippo, pid3).

5. I run the controller that upon connection it receives the BotUpdateList with 3 objects with possible identification by name, sessionId (sid in short), host and connection port:

• (pippo,sid1,host,port1)
• (pippo,sid2,host,port2)
• (pippo,sid3,host,port3)

6. when the match is running, via TickEventForObserver, I get as bot updates, these 3 objects with possible identification by id only:

• (id1)
• (id2)
• (id3)

In this example, where the 3 bots have the same name and same host, is impossible to match the 3 same bots in the 3 lists among each other. Not even the Controller itself can match the bots in the list given within the TicksEventForObserver with the ones given in the BotListUpdate.

Thanks for reading this far

json $type field problematic with python code generation

Describe the bug
I'm trying to generate some python clients from the given json schema. I'm using https://github.com/koxudaxi/datamodel-code-generator/ , and the $type field is giving me lots of grief.

Since python can't use special chars in var/param names, I'm wondering if there's some reason this field needs to have a $?

Error info
All sorts, there's no easy code gen from existing json schema tooling.

New version 0.21.0 freezes starting battle

Describe the bug
New version 0.21.0 freezes starting battle

To Reproduce
Launch 0.21.0 version gui jar from Kubuntu 22.04LTS, go to Battle, Start Battle... the app freezes, you can't select bots from samples bot and boot them. I have to close the app by the force. No error or debug information on console

Error info
No error shown

Expected behavior
Select bots, boot them and start battle, with version 0.19.3 it works very well.

Blocking bot functions do not stop bot after finishing

I tested this for Bot.forward, Bot.back, and Bot.turnGunRight. When the run function contains only one of these calls, I would expect the bot to perform the action and then remain still. However, the bot instead continues the motion.

For example, consider this run function:

@Override
public void run() {
    forward(100);
}

I would expect the bot to move forward 100 pixels and then stop. However, the bot instead moves forward 100 pixels, and then slowly creeps forward indefinitely. The problem is not that run is a loop. I tried this function as well:

@Override
public void run() {
    forward(100);
    back(100);
}

In this case, the bot moves forward 100 pixels, backs up 100 pixels, and then slowly creeps backwards indefinitely.

Java - `turnRight` and `turnLeft` never stop turning if last function

Version: Java

If the last function called in run is turnLeft or turnRight, the robot turns and never stops turning. If another function (e.g. forward) follows one of these two functions, the robot stops turning and performs the next action, as expected.

Some thoughts. This is similar to #17, which was recently fixed for forward and back. Now, these two functions are experiencing another issue in #22. When this problem with turnLeft and turnRight is looked at, hopefully the solution does not lead to similar #22 issues.

Battle does not restart

Describe the bug
When battling the "Target" and "Walls" C# sample robots, hitting "Restart" does not restart the battle. Instead the battle ends but does not restart. In the resulting state, hitting Ctrl+B to start a new battle does not open up the appropriate menu. To start a new battle, I had to close and reopen the GUI.

To Reproduce
Steps to reproduce the behavior:

1. Run robocode-tankroyale-gui-0.11.0.jar
2. Press Ctrl+B.
3. Run Target and Walls (from sample-bots-csharp-0.11.0)
4. Click "Add All"
5. Click "Start Battle"
6. Click "Restart"
7. Observe that the battle does not restart

Error info
No error message is displayed, as far as I can tell.

Expected behavior
The battle restarts when I click "Restart".

Desktop (please complete the following information):
-Windows 10

Java info:
openjdk version "11.0.14.1" 2022-02-08
OpenJDK Runtime Environment Temurin-11.0.14.1+1 (build 11.0.14.1+1)
OpenJDK 64-Bit Server VM Temurin-11.0.14.1+1 (build 11.0.14.1+1, mixed mode)

Additional context
This reproduces pretty consistently for me, but the issue does not occur every single time. While typing the steps up for this issue, I reproduced the problem several times. However, there was one time where the restart button did work correctly. This occurred when I had left the battle creation menu open for some time before actually starting the battle.

Some configuration options I used:
initial-position-enabled=false
tps=30

Fire and Explosion Sounds

Hi,

First of all, thank you for creating an upgraded platform for robocode.
I love it! especially the fact that it enables me to use the latest .NET Framework.

Regarding sound (Firing and Tank Explosions), just wanted to inquire if this is already in place and perhaps my setup hasn't just enabled it (i.e. no sound by default). or there is really no sound as per the latest version?

feel free to reply and close when you get some time :-)
stay awesome!

Turn two is skipped (?)

Describe the bug
It seems like the second turn of my robot is skipped.

To Reproduce
Steps to reproduce the behavior:

1. Create a testing robot that prints out the current turn in its Run member. Working in F#, I used the following code:

    override this.Run() =  
            while(this.IsRunning) do
                use writer = File.AppendText("log.txt") 
                writer.WriteLine("It is turn: " + (string this.TurnNumber))                 
                this.Go()

2. Create a battle with this testing robot and some other robot (I used Target).
3. Let the battle run for a few seconds.
4. Examine the log file "log.txt"

Expected behavior
I would expect each robot to be able to act on each turn. In particular, I would expect the log file created above to include the line "It is turn: 2".

Screenshots
The start of the resulting log file:

Bring original robocode bots to new platform

I quite like the new and modularized design, where bot creation is no longer limited by JVM. One can write e.g. a Python bot, finally, and even take advantage of GPUs. Imagine a whole new level of robocode competition!

Anyway we have a lot of ancient bots in original robocode, no longer updated by their authors. Yet their strategy is sophisticated, and is still inspiring new authors. Theoretically one can simply write a bridge, translate math coordinates, since the rest of game physics is mostly equivalent. However, such a bridge is error-prune, and may get out of maintenance, which creates fragmentation to the community.

If there were an officially supported bridge, it will be much easier to go with the new platform, with the benefit of the existing community and bots, out of the box. And I'm glad to help if there are already some plans ;)

Questions about seemingly inconsistent behavior

I want to make a bot that moves in a circle. I coded this in multiple ways that I assumed would behave the same. However, they each have different behaviors. Some of these different behaviors may be intentional, I am just curious about them.

setTurnRight(Double.POSITIVE_INFINITY);
forward(Double.POSITIVE_INFINITY);

This behaves how I would expect. The bot moves in a circle. If it hits an obstacle, it continues attempting to move in a circle. All is well and good

setForward(Double.POSITIVE_INFINITY);
turnRight(Double.POSITIVE_INFINITY);

This behaves similar to 1; the bot moves in a circle. However, if it hits an obstacle, it stops moving forward and spins in place. It seems like forward maintains distance remaining when the bot runs into something, but setForward does not

setForward(Double.POSITIVE_INFINITY);
setTurnRight(Double.POSITIVE_INFINITY);

The bot does not move at all. I expected this because I do not call go, and the documentation says that go must be called every turn if using these functions. Although this seems obvious, I thought there might be a chance that go is called automatically after the run function completes.

setForward(Double.POSITIVE_INFINITY);
setTurnRight(Double.POSITIVE_INFINITY);
go();

The bot moves in a tiny circle. Due to my misunderstanding of go, I was expecting this to either move for a single turn and then stop, or move similar to 1 and 2. However, the forward speed is much smaller than these previous cases. Additionally, it seems like bumping into obstacles does not eliminate its forward movement like 2, even though setForward is used here as well.

I should also mention when I was testing this case, I threw the following exception once at the beginning of a run. This exception seems to occur rarely for some reason, and I think it could have happened during any of these cases.

Exception in thread "Thread-28" java.lang.IllegalArgumentException: -Infinity is not a valid double value as per JSON specification. To override this behavior, use GsonBuilder.serializeSpecialFloatingPointValues() method.

setForward(Double.POSITIVE_INFINITY);
setTurnRight(Double.POSITIVE_INFINITY);
while (true) {
    go();
}

The bot spins in place. Also, when I choose to restart the battle, the battle does not begin. To retry, I have to close the bot process and start it anew. I actually expected this to be the correct way to code a circle bot. The documentation for go says that it must be called every turn, so putting it in a while loop seemed the best way to ensure this. I thought if go is not called, actions would not be sent to the server, hence why I thought case 4 might have the bot only move for a single turn. Currently though, it appears that putting go in a loop with nothing else causes the most problems.

Server is kidnapping CPU cycles

Describe the bug
Version of the server 0.17.1, the server after a while reaches high level of CPU % taken, to my old macBookPro from 2012 is reaching 100% or more, I monitor the process using the tool htop and filtering with the keywork tankroyale
The problem doesn't look to appear until a game is started but when happens doesn't matter if the game is aborted or the bots are disconnected/unbooted/killed, the server is getting hold of my CPU

To Reproduce
Assuming the problem is not just related to me, boot up a server, join some bots, run a game, stop the game, un-run the bots. Monitor the CPU usage from the server on each step.

Expected behavior
server to use any CPU is required to him during the battle and releasing it when the battle is finished

Screenshots
htop screenshots, ignore the blue higlighted row and fcus on the server row and the CPU% column

Server just started:

Walls and Crazy joined

Game started

Game aborted

Bots killed (after the games i aborted in order to avoid any illegal disruption of the game)
