------------ 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)
