Unity 2D layer collision not working

Question

I have two objects: "Player" is an object that has a box collider 2d and a rigidbody2d, and is set on the "player" layer. "Enemy" is an object that only has a box collider 2d, and is set on the "enemy" layer.

When the player moves, I want it to get stuck on the enemy if they touch, but the collision doesn't work, and they go through each other. I tried using this: https://docs.unity3d.com/Manual/LayerBasedCollision.html but it still isn't working. The layer collision matrix looks like this: alt text

Is there anything I'm missing? Any help would be appreciated ^^

Note:player and enemy objects details are in comments

I figured it out! Turns out that the problem was the "kinametic" body type of the rigidbody of the player object. I changed it to "Dynamic" and set the gravity scale to zero. That way, the player collides with the enemy and still works as intended (moving around and dealing damage).

@Lineweaver You have "Is Trigger" checked on your enemy object collider. That means the objects won't collide with the rigidbody and will only trigger the OnTriggerEnter method.

If that wasn't your intention, try unchecking that box and see what happens

Thank you for the reply, but the player object still goes through the enemy, even when both objects have "Is Trigger" unchecked..
