Following up on a Discord discussion, it looks like the position given in `contact_point_event` is different from that in `contact_point_response`:

[ContactPointResponse.zip](https://forum.defold.com/uploads/short-url/pJ6sgjvcAp0PbhQRcTlA1JtsXFa.zip) (5.0 KB)

I’d like to use physics.set\_listener(), but I’m geen to get the contact point position, rather than the collision object position. Still unsure if the position given by contact\_point\_event is by design, or if I’m missing something?

Yes, in the [contact\_point\_response](https://defold.com/manuals/physics-messages/?q=contact_point_response), the contact point itself is the main subject:

> `position`  
> world position of the contact point (`vector3`).

whereas the [contact\_point\_event](https://defold.com/ref/stable/physics/?q=contact_point_event#contact_point_event) returns a single event, where each point is the position of each object:

> position  
> vector3 The world position of object A

I agree that it’s not great to not report the local point of the collisions.  
Please feel free to report an issue!
