OnCollision2D stopped working

Hello community,

I've asked this question in unity answers and got no replay yet (link), so I decide To try here.

I have a weird issue with OnCollision2D.
I've setup my player with a 2D collider, I've also setup the ground he is walking on with a 2D collider.
The player also has a 2D rigidbody on it, the ground does not.
The player script (attached to the player) has 2 OnCollision2D methods, OnCollisionStay2D and OnCollisionExit2D.
The player also has an animator that animates its sprite.
At that point, everything is working fine, both OnCollision2D methods are being called.
Then, I added another animation to the character.
In that animation, I'm also animating the colliders (changing their shape and size).
As soon as I added this new animation, both of the OnCollision2D methods stopped working, even before I'm calling the new animation.
If I disable the Animator component on the player, then the methods are working again.

Any ideas?

 

Hmm, I animate colliders all the time without issue. Are you applying root motion? Are you rotating child colliders with a negative scale?

 

I'm not applying root motion and I'm not rotating anything, just changing center and scale of a collider.

I'm not even sure if animating the collider is the issue, I just now this accord approx the same time I added it.

The weird thing is, The methods just don't work, even if I haven't played the animation yet.

 

this seems like a common issue, i noticed collision hooks stopped working properly when i added animations to my entity.

 

Did you set the Rigidbody2D to kinematic? It seems that colliders don't work unless at least one of them is associated with a Rigidbody2D that is NOT kinematic.

 

Non of the rigidbodys is kinematic.
The collsion is working fine, the colliders are colliding each other, its just the methods that don't run.
