Not quite sure why this is a thing, but it is. For one of the tutorial stages of this shooter game I'm making, there are two enemies encased in breakable rocks. Upon breaking the rocks, the enemies should be set loose, and begin to chase the player. However, they don't. I had a theory, and so I gave it a test. I was correct. For whatever reason, even though the rock isn't there anymore, the spot where the rock used to be is blocking the enemies line of sight to the player. There is no object to block it, it's as if the rocks ghost is magically blocking the path. Any ideas for why this is happening?
