Hi everybody,
I am trying to program a “Tower Defense” game.
My battlefield is a plan where I put a NavMesh. The mobs (ennemies) appear on the left and try to go until the very right. The player builds tower to kill them on their way.
When the player selects a type of tower he wants to build, I color the different “squares” of the battlefield where he can build it. Green if OK, red otherwise. The player cannot build if it blocks the way of course.
To measure that, I instantiate a “fake” Nav Mesh Obstacle on a square, then I recalculate the path from the departure until the arrival. I apply the good color on the square according to the resulting status. Then, I destroy the fake obstacle.
Here is my problem :
After instantiating my fake NavMeshObstacle, I must wait a few amount of time before calculating. If I don’t, the NavMesh won’t be impacted by the new obstacle, hence the calculation will be wrong.
Is there any possibility to determine when the NavMesh have been changed by a new Obstacle ?
Thanks,
Samoustique
