Why is my collision response message not received?

Questions

Hey! I have a dynamic collisionobject that collides with a static object. I can’t catch the collision message.
This code just does nothing:

function on_message(self, message_id, message, sender)
	if message_id == hash("collision_response") then
		go.delete(id)
		sound.stop("#bombwhistle")
		check = 0
		print("collision")
	end
end

Are you sure the two objects are colliding? Do they have matching collision groups and masks? Enable physics debug to see what’s going on:

PS When you share code make sure to surround it with three back-ticks like this

```

They are a bomb and a house. They collide, the bomb bounces on the house. Regarding the groups and masks I haven’t done anything.

Is the script part of the same game object as the collision object?

Yes, I just can’t get a collision response. I set the group and mask, as well. I am trying to make it as simpla, as possible, but I can’t make this code work:

function on_message(self, message_id, message, sender)
	if message_id == hash("collision_response") then 
		print("Collision")
	end
end

It just does nothing.

Ahhh… you were right. It wasn’t part of the same gameobject!

Are they in they both instanced under the same collection? I’ve experienced something like this a while ago, and I found that if you spawn the two using factories in the same collection, it solves the problem.
