------------ Training Mission 7 - Predict Position ------------
This map is designed to train you on using a rocket launcher.
It is a rectangular map with a monster on the opposite side. You need
to use your rocket launcher to kill it. The rocket adds a delay between
the moment it is fired and the moment it reaches the other side of the room.
You need to predict the position of the monster to kill it.
Allowed actions:
[0] - ATTACK - Shoot weapon - Values 0 or 1
[13] - TURN_RIGHT - Turn right - Values 0 or 1
[14] - TURN_LEFT - Turn left - Values 0 or 1
Note: see controls.md for details
Rewards:
+ 1 - Killing the monster
-0.0001 - Several times per second - Kill the monster faster!
Goal: 0.5 point
Kill the monster
Hint: Missile launcher takes longer to load. You must wait a good second after the game starts
before trying to fire it.
Ends when:
- Monster is dead
- Out of missile (you only have one)
- Timeout (20 seconds - 700 frames)
