I'm trying to make an object come towards me. To do this, I move the item I want to come towards me in all possible directions by 1. Whichever direction moves the object closes to me, I move it in that direction. The object will move in my general direction, but it will just continue on past (not through) me and off into infinity. My code is:
Why don't you just get the direction vector and move along that?
Seriously, it's as simple as this: (pseudocode)
Hope this helps.
Seriously, it's as simple as this: (pseudocode)
float distanceToMove = 1.0f; // Or whatever you want it to beVector3 direction = _camera.Position - obj.Position;direction.Normalize();obj.Position += direction * distanceToMove;Hope this helps.
