Follow this installation guide. It will also show you how to download the bot pack containing bots like Kamael and Botimus Prime. Note, RLBot only works on PC both with Epic and Steam.
The best bot is Nexto for both 1v1, 2v2, and 3v3. It is around GC rank in terms of skill and can be found in the bot pack.
Here is a summary of other bots in the bot pack:
Notes: Self-driving car and Stick have no teamplay. Codename Cryo is best with 2 teammates.
The RLBot framework cannot be used online. The API is only activated when the game is started with a special RLBot setting which disables online play. You can be banned without warning if we suspect that you have malicious intent (farming, levelling, etc.). We want to stay on Psyonix's good side here.
You can! It requires setting up a LAN/VLAN connection. Here is a guide.
It is not possible to play with friends cross platform.
Most are hardcoded and do not use machine learning. However, since the release of RLGym the machine learning are progressing faster than ever. If you are interesting in making a ML bot yourself, start by reading the ML FAQ.
Some ML projects to check out are:
You can find example bots in each language on the frontpage showing off the basics and various features.
We also have a few tutorials:
Addition resources, documentation, and examples can be found on the RLBot wiki. Feel free to ask for help in the Discord server in the appropriate language channel or in the #strategy or #mathematics channels.
The GameTickPacket is a packet sent to your bot each tick. It contains information about everything that tends to update during the game. For instance, the location and velocity of all cars and the ball, the state of boost pads, the time elapsed.
The FieldInfo contains information that is static throughout the game. For instance, the location and size of boost pads and the location of goals.
More information about the GameTickPacket, FieldInfo, and even the ControllerState can be on the RLBot wiki.
RLBot uses an API in Rocket League specifically made for us. This API is activated when the game is launched with the '-rlbot' flag, which simultaneously disables all online play. The RLBotCore dll communicates with the game through this API and this is where most of the magic happens. Communication with bots are done through sockets (shared memory in the past) which allow us to support a wide range of languages.
