-- Genre two of milestone 4: tower defence. Creeps that walk a lane on the navigation mesh in
|
|
-- waves, turrets placed with a click on the floor that fire at the nearest creep in range,
|
|
-- projectiles that collide, gold and lives. Nothing here is shared with the racing game but the
|
|
-- scene.
