A C++ library for simulating Rocket League games at maximum efficiency
- Clone this repo and build it
- Use https://github.com/ZealanL/RLArenaCollisionDumper to dump all of Rocket League's arena collision meshes
- Move those assets into RocketSim's executing directory
Coming Soon:
- Version 1.0 release
- Significant collision optimizations
- Make half-percision 60tps simulation viable
Done:
- Car suspension
- Car driving
- Car jumps and flips
- Arena collision
- Proper ball bounces
- Car-ball collision with proper forces (will be refined more in the near future)
- Boost usage and boost pads
- Bumps and demos
- Auto-flip when upside-down
RocketSim is not perfectly accurate, but it's close enough that it shouldnt matter (for ML bots or humans). Bots that work well in RocketSim will work well in the actual game, and visa-versa.
#include "./RocketSim/src/Sim/Arena/Arena.h"
// Make an arena instance (this is where our simulation takes place, has its own btDynamicsWorld instance)
Arena arena = Arena(GameMode::SOCCAR);
// Make a new car
// NOTE: The ball and all cars are freed from memory when their arena is deconstructed, you don't need to do it yourself
Car* car = arena.AddCar(Team::BLUE);
// Set up an initial state for our car
CarState carState = {};
carState.pos = { 0.f, 0.f, 17.f };
carState.vel = { 50.f, 0.f, 0.f };
car->SetState(carState);
// Setup a ball state
BallState ballState = {};
ballState.pos = { 0.f, 400.f, 100.f };
arena.ball->SetState(ballState);
// Make our car drive forward and turn
car->controls.throttle = 1;
car->controls.steer = 1;
// Simulate for 100 ticks
arena.Step(100);
// Lets see where our car went!
std::cout << "After " << arena.tickCount << "ticks, our car is at: " << car->GetState().pos << std::endl;Feel free to make issues and pull requests if you encounter any issues!

RocketSim was written to replicate Rocket League's game logic, but does not actually contain any code from the game. To Epic Games/Psyonix: If any of you guys have an issue with this, let me know on Discord and we can resolve it.
