Here’s a checklist of possibilities:
Check the layers and tags of the objects involved in the collision. Make sure that the layers and tags of the objects match up correctly so that the collision can occur.
Ensure that the Capsule Collider 2D is properly positioned and sized around Barry. If it’s too small or positioned incorrectly, the collider may not detect collisions properly.
Check the settings of the Edge Collider 2D on the Level Sprite Shape. Ensure that it covers the area where Barry is falling, and that it’s set up correctly to detect collisions.
Try adding a Rigidbody 2D component to Barry if you haven’t already. This will add physics properties to Barry and may help with collision detection.
Check the physics settings in your Unity project. Ensure that the physics engine is set up correctly, and that the collision detection settings are appropriate for your game.
My hope is that one of these help you!
