I have a 3D model of a board game. Peg Solitaire to be exact. I created my board in Blender with holes and so on.
Now I have my spheres and they are placed on the board. What I don't know how to solve is to make sure that the translation of the spheres is only possible to the position of the holes. So they can't be moved to any other place on the board not having holes.
Someone told me to use a Grid. My question is, how should I create this grid?
2D or 3D grid?
Any examples, tutorials ?
