Game Development Reference
In-Depth Information
1.
Tank will randomly change direction every
turn_time
interval, which is
between 2 and 5 seconds.
2.
Tank will choose to drive (80% chance) or to stand still (20% chance).
3.
If tank chose to drive, it will keep driving for
drive_time
, which is between 1
and 5 seconds.
4.
Same goes with waiting, but
wait_time
(0.5 - 2 seconds) will be used for
duration.
5.
Direction changes and driving / waiting are independent.
This will make an impression that our tank is driving around looking for enemies.
Tank Fighting State
When tank finally sees an opponent, it will start fighting. Fighting motion should be more
energetic than roaming, we will need a sharper set of choices in
change_direction
among other things.
