title: Unity 2D games, I have troubles with 2D collliders
body: <p>I have a lot of problems with some 2D colliders.
  In the past, they work, but now they are horrible:))
  I already try with Kinematics, OnCollision2DEnter, OnTriggerEnter etc.
  The objects are already on the same layer, the same position on the Z-axis, they interact with each other but my game can't detect the collisions.
  The rigidbody and collider don't have material but the objects have skins <a href="https://i.stack.imgur.com/k3rxj.png" rel="nofollow noreferrer">enter image description here</a><a href="https://i.stack.imgur.com/LcK82.png" rel="nofollow noreferrer">enter image description here</a></p>
