I'm making a fps game, I have 2 question.
first: The enemy Ai (zombies) are getting caught on eachother and I was wondering what I could do to make them go through eachother but not any other objects.
second: I want to make a ui in game. for example: You click G and a menu comes up and you can buy stuff etc. I have the points set up but I'm not sure how I would add the UI and make things cost a certain number of points.
