Basic Collision Question

Hi guys, If my sphere collides with a wall I make the resting place exactly the radius away. But then isn''t it still colliding ? Should the distance from the center of the sphere to the wall be less than the radius or less than or equel for a collision to occur ? Thanks.

that''s what''s called a resting contact, or contact.

To simplify, to avoid another immediate contact, if that bothers you, you can put the sphere position at a distance radius + 1 milimiter (or more) away from the wall. The sphere would jitter slightly if you try to keep pushing the sphere towards the wall.
