Bot Making

Starting a JavaScript Bot

The first thing you'll want to do is start a class that extends the rlbot.BaseAgent class. This allows you to easily accomplish things that are harder without extending the BaseAgent, like sending quick chats. You'll also need to make a new Manager that has a parameter of the class extending BaseAgent.

Example:

const { BaseAgent, SimpleController, Manager } = require("rlbot-test");

class MyBot extends BaseAgent {
    constructor(name, team, index, fieldInfo) {
        super(name, team, index); // pushes these all to `this`.
        console.log(this.name); // Print our name to the console,  e.g. "MyBot"
    }

    getOutput(gameTickPacket, ballPrediction, fieldInfo) {
        return SimpleController(); // Do nothing in-game
    }
}

const manager = new Manager(MyBot); // This makes a manager
manager.start(); // This starts the manager

API Reference

BaseAgent(name, team, index)

You shouldn't be calling new BaseAgent, instead you should extend it! See the example

.getOutput(gameTickPacket, ballPrediction) -> SimpleController

Once again you shouldn't be calling this function, you should be implementing this function!

gameTickPacket: The object containing all the current field data, see gameTickPacket
ballPrediction: The object containing all the future positions of the ball, calculated using Chip's notes, see ballPrediction for the structure
Return a SimpleController

.sendQuickChat(quickChatSelection, teamOnly)

quickChatSelection: See quickChats
teamOnly: A boolean, determines if the quickChat should be visible to the team only or not

Example:

//top of the file
const { quickChats } = require('rlbot-test')

//inside your bot class
this.sendQuickChat(quickChats.compliments.NiceShot, false)

.setGameState(GameState)

This allows to set the state of the game

GameState: a new GameState, see GameState for refrence

Example:

let physics = new Physics(null, null, new Vector3(null, null, gameTickPacket.ball.physics.velocity.z+(650/60))) //assumes you are running 60fps
let ball = new BallState(physics) 
this.setGameState(new GameState(ball))

GameState

new GameState(ballState: BallState, carState: Array<CarState>, boostState: Array<BoostState>, gameInfoState: GameInfoState)

new GameInfoState(worldGravityZ: Number, gameSpeed: Number)

new BoostState(respawnTime: Number)

new CarState(physics: Physics, boostAmount: Number, jumped: Boolean, doubleJumped: Boolean)

new BallState(physics: Physics)

new Physics(location: Vector3, rotation: Rotator, velocity: Vector3, angularVelocity: Vector3)

new Rotator(pitch: Number, yaw: Number, roll, Number)

new Vector3(x: Number, y: Number, z: Number)

Game data objects

SimpleController

{
  throttle:float; /// -1 for full reverse, 1 for full forward
  steer:float; /// -1 for full left, 1 for full right
  pitch:float; /// -1 for nose down, 1 for nose up
  yaw:float; /// -1 for full left, 1 for full right
  roll:float; /// -1 for roll left, 1 for roll right
  jump:bool; /// true if you want to press the jump button
  boost:bool; /// true if you want to press the boost button
  handbrake:bool; /// true if you want to press the handbrake button
  useItem:bool; /// true if you want to use a rumble item
}

throttle: Default is 0. To go forward, change this to 1. To go backwards, change this to -1. Setting this to 0 will stop the throttle. NOTE: Setting this to 0 does not slow the car down very well. If you want to brake, change the throttle to the opposite from what it was. E.g. when this is set to 1, set this to -1 until the bot has slowed down.
steer: Default is 0. To steer right, change this to 1. To steer left, change this to -1. Setting this to 0 will steer forwards.
pitch: Default is 0. To tip the bot forwards, change this to -1. To tip the bot backwards, change this to 1. NOTE: Changing this is a way to dodge.
roll: Default is 0. To roll clockwise(relative to the back of the car), change this to -1. To roll anti-clockwise(relative to the back of the car), change this to 1. NOTE: Changing this is a way to dodge.
yaw: Default is 0. To rotate the bot clockwise(relative to the top of the car), change this to -1. To rotate the bot clockwise(relative to the top of the car), change this to 1. NOTE: Changing this is a way to dodge.
boost: Default is false. To use boost, change this to true. To not use boost, change this to false.
jump: Default is false. To jump, change this to true. To not jump, change this to false
handbrake: Default is false. To powerslide, change this to true. To not powerslide, change this to false.
useItem: Default is false. To use a rumble item, change this to true. To not use a rumble item, change this to false.

Setting up a development environment

You'll need:

Node.js
Python 3.7
windows-build-tools, which you can get with node.js by running $ npm install -g windows-build-tools in an administrator terminal. This is used to build some dependencies that are in C or C++.

Fork this repo (if you aren't a collaborator)
Clone your fork or SuperVK/RLBotJS with: $ git clone https://github.com/[username/SuperVK]/RLBotJS.git
Clone the example bot with: $ git clone https://github.com/SuperVK/RLBotJavascriptExample.git
Go into RLBotJS: $ cd ./RLBotJS
Install deps: $ npm install
Make changes
Link it globally: $ npm link or skip this step
Go into the example: $ cd ../RLBotJavascriptExample
Link it with the changes you made: $ npm link rlbot-test. If you skipped step 7 run $ npm install ../RLBotJS instead
Test your changes with run.bat in the rlbot folder of the example bot or the new GUI
You're all done! Now, you might want commit your changes (in the RLBotJS directory) and push those changes (in the RLBotJS directory), and then make a pull request.
