Now my 3D model has complete AI behaviours, but my model has no collision avoidance while he is moving towards the player! Because of this, he gets stuck in front of 3D blocks sometimes.
I think the solution includes the usage of rays. I've included a picture of what I want to do.
NOTE: The world is a 3D world, not a 2D one. (Even though they are almost the same)
I want my model to not collide with the boxes while he is moving towards me, i.e make some collision avoidance. :)
