Hey thank you for your reply, this is probably a clever solution, I will check that, but I was looking to something that I can use with more complexe collider as those made with polygon collider. That’s why I used bounds.Contains, I have you got something with that ? I am still not able to get around the probleme of the World space.
Ps: for those who don’t know a quick solution is simply to add a boxCollider on the sprite which then works as a 3D plane.
