Simulation

Car

Car simulation when on the ground is limited. 1D simulation of a car driving along a path is partially supported, but predicting the car's future locations from an initial state and a sequence of controls is not possible, at present.

However, simulation of jumping, dodging (including canceled dodges in the near future), and aerials are all supported.

ground control

aerial reorientation control

Ball

Regular ball simulation follows the theory presented here.

Car-ball interactions are also modeled according to the collision mechanics outlined here.

examples

basic ball prediction in Python:

from rlutilities.linear_algebra import vec3
from rlutilities.simulation import Game, Ball

# configure the Game to use the soccar collision geometry
Game.set_mode("soccar");

# make an instance of a Ball object
b = Ball()

# initialize it to a position in the middle of the field, some distance above the ground
b.position = vec3(0, 0, 1500)
b.velocity = vec3(0, 0, 0)
b.angular_velocity = vec3(0, 0, 0)

for i in range(120):

    # calling step() advances the Ball forward in time
    b.step(1.0 / 120.0)

    # and we can see where it goes
    print(b.position)
