Is there a way to prevent the collision shapes from overlapping ? That the character stops moving to the left once the collision objects detect the wall? Completely accurately?

Does anyone know how to accurately prevent the spheres from overlapping? To have accurate collisions?

The idea is that the top portion of the code you shared should separate contact points so that there is no overlap. In your screenshot it will overlap a bit every frame when moving left and then get separated again on the same frame. You should not see any jittering or similar in the movement while moving against the wall.

without the collision box " pressing in " like that

But you are not going to have the collision box visible in the released game will you? And as long as the actual sprite is not jittering then I don’t really see the problem?

or getting stuck.

There is a reason the template project uses spheres and not boxes. Boxes and their sharp corners tend to get stuck like in your video. Change back to spheres.

You could try a combination of spheres and a ground box.
