okay, here’s a first version of the code, it’s features are:
-squad movement
-finding cover
-attacking
-following waypoints
-etc…
These parts aren’t working correctly:
-finding cover(
(the characters simply stay stuck in the walls sometimes…)
-following waypoints
(I don’t know why this isn’t working)
