Why does an object go through walls?

Question

C++ / C#

The walls have Box Collider 2d , as does the player.
What to do?

Answer 1

You cannot move physics through a standard transform component.
Add a rigid body and move through it - Rigidbody.MovePosition(), or better by adding a movement impulse - rb2D.AddForce(transform.up * thrust, ForceMode2D.Impulse);
