Usage

from curling import Curling, SimulationConstants, StoneColor, StoneThrow
import numpy as np

accurate_constants = SimulationConstants(time_intervals=.05)

# leave blank for a random starting stone
current_player = StoneColor.RED
curling = Curling(current_player)
curling.reset(starting_color=current_player) # optional for first game

for i in range(curling.num_stones_per_end):
    current_player = curling.next_stone_color
    # throw a stone
    curling.throw(
        StoneThrow(
            color=current_player,
            # sqrt velocity is specified
            sqrt_velocity=np.random.uniform(1.35, 1.46),
            angle=np.random.uniform(-.06, .05),
            spin=np.random.uniform(2., -2.),
        ),
        display=True, # false by default
        constants=accurate_constants # leave blank for the best trade off between speed and accuracy
    )

print(curling.evaluate_position()) # positive for YELLOW and negative for RED
