rlbotflatbuffers 0.8.1

rlbot-flatbuffers-py
A Python module implemented in Rust for serializing and deserializing RLBot's flatbuffers
The goal of this project
To provide a fast, safe, and easy to use Python module for serializing and deserializing RLBot's flatbuffers.
A majority of the code is generated in the codegen/ upon first compile and thrown into src/python.
This includes the code generated by flatc (living in src/generated), the Python wrapper binds to the generated Rust code, and the Python type hints (rlbot_flatbuffers.pyi).
Basic usage
All classes and methods should have types hints readable by your IDE, removing the guesswork of common operations.
Creating
import rlbot_flatbuffers as flat

desired_ball = flat.DesiredBallState(
physics=flat.Physics(
location=flat.Vector3Partial(z=200),
velocity=flat.Vector3Partial(x=1500, y=1500),
angular_velocity=flat.Vector3Partial(),
),
)

desired_game_info = flat.DesiredGameInfoState(
world_gravity_z=-100,
game_speed=2,
)

desired_game_state = flat.DesiredGameState(
ball_state=desired_ball,
game_info_state=desired_game_info,
)

In the above code, we:

Set the ball to:

Location (0, 0, 200)
Velocity (1500, 1500, 0)
Angular velocity of (0, 0, 0)

Don't set the car states
Set the game info state:

World gravity to -100
Game speed to 2x default
Don't set end match or paused

Don't set any console commands

All values are optional when creating a class and have the proper defaults.
Reading values
import rlbot_flatbuffers as flat

def handle_packet(packet: flat.GameTickPacket):
if packet.game_info.game_state_type not in {
flat.GameStateType.Active,
flat.GameStateType.Kickoff,
}:
# Return early if the game isn't active
return

# Print the ball's location
print(packet.ball.physics.location)

for car in packet.players:
# Print the every car's location
print(car.physics.location)

The goal of the above was to feel familiar to RLBot v4 while providing a more Pythonic interface.

All classes (not enums and unions) implement __match_args__ for easy destructuring via the match/case pattern.

Enums and unions and can still be used to match against the type,
they just can't be destructured.

Every class implements __str__, __repr__, and __hash__ methods.

All enums also implement __int__ and __eq__.

Lists no longer have num_x fields accompanying them,
they are just Python lists of the appropriate length.
