I\'m making a Doom style game, which means it is in first person and uses 2d images on object plains, and 3d objects. I want to know how to detect a 3d object colliding with a object plain to stop the camera from going through the wall along with the object. I set it so there is an object where the camera is. The problem with the collision is that when the object hits the plane it moves me to the same every time. I have no idea why and i would appreciate help.
