Training Command:

python3 -m imitation_agent.train -e 1 -v AI_L2x256_blue --time_steps 500000 --time_steps_infer 10 --nenv 2 --use_opponent --expert jurgen_agent --batch_size 512 --device cuda --md 90 --net_arch "256,256"

Command for creating jit compatible file:

python3 -m imitation_agent.canvas_jit -e 1 -v AI_L2x256_blue_error --time_steps 1 --time_steps_infer 10 --nenv 1 --use_opponent --expert jurgen_agent --batch_size 512 --device cuda --md 90 --net_arch "256,256" --resume_training "AI_L2x256_blue/AI_L2x256_blue.pt"

1. Minimize "kart_to_puck_dist"
   • Rewarding the player (it increases exponentially): np.exp(-x)
   • TODO: Check if normalizing the values helps or not
2. Aligning the player-puck-opponent goal post
   • 1st vector: (puck - player)
   • 2nd vector: (opponent goal post - player)
   • Use cosine similarity b/w the two vectors
3. Reward for scoring the goal
   • Minimize the distance b/w ball and goal post

1. Reward for not allowing the ball in a region

1. Reward based on current match state

player_state

• camera (https://pystk.readthedocs.io/en/latest/state.html#pystk.Camera)

• Not needed????

• Kart (https://pystk.readthedocs.io/en/latest/state.html#pystk.Kart)

• attachment - types of attachment

• front - Front direction of kart 1/2 kart length forward from location - float3

• id - Kart id compatible with instance labels - int

• jumping - Is the kart jumping? - bool (Not needed I think)

• location - 3D world location of the kart - float3

• max_steer_angle - Maximum steering angle - float

• name - Player name - str

• overall_distance - Overall distance traveled - float (Not needed I think)

• player_id - Player id - int

• powerup - Powerup collected - powerup

• rotation - Quaternion rotation of the kart - Quaternion

• velocity - Velocity of kart - float3

game_state

• ball

• id - Object id of the soccer ball - int

• location - 3D world location of the item - float3 ( )

• size - Size of the ball - float

• goal_line (static) - Start and end of the goal line for each team - List[List[float3[2]][2]]

• kart_direction - float2

• kart_to_puck_angle - float

• kart_to_puck_angle_difference - float

• kart_to_opponent0 - float2

• goal_line_center - float2

• puck_to_goal_line - float2

• puck_to_goal_line_angle - float

• kart_to_goal_line_angle_difference - float

Somethings that can help

• ball velocity
• ball acceleration?

• agents velocity towards ball
• balls velocity towards goal
• +ve reward on goal

• -ve reward on opponent goal
• +ve reward if shot on target
• +ve on making a save
• +ve on impeding opponent

psuedo code for necto rewards

• game state reward = ball_pos closer to goal (continuos)

• How does it know to reverse?
• continous space
• how can i train with some base agent
• circiculum learning - ppo
• action space
• rewarding shaping
