9 years ago Right now it's not possible to get the collide event between static / kinematic or kinematic / kinematic. So you'll have to work around it. There are a few ways.
For example, you could use a veeery heavy dynamic body and turn off gravity. Apply gravity manually on other dynamic bodies.
Another way is to add a dynamic body and sync its position with the kinematic one. Use it only for catching the events.
If you use simple shapes, you could probably implement the collision detection manually.
Or use the Narrowphase to see if the bodies overlap (untested code):
var result = []; world.narrowphase.getContacts([bodyA], [bodyB], world, result, [], [], []); var overlaps = result.length > 0;
Collision events for kinematic bodies is something that will be added. It is straight forward to implement but will need some work.

Hello there
I'm trying to get objects flying around with a constant velocity, unaffected by gravity or anything. So far i'm using kinematic objects to achieve that. My issue is, that I still want to be able to detect collisions between these objects and other, static objects. I don't need anything to happen to the objects on collision, but I want to be able to detect when it happens.
Kinematic objects don't emit collisions with static bodies. So how should I approach this? Can I somehow get the collision event to show up anyways or do I have to get rid of the kinematic type?
