Any libs for collision detection that don't work like bump.lua?

What I mean by title is a collision detection library that dosen't require every bounding box of everything in the scene to be defined beforehand. I'd perfer one where you can just call a single function with the coords/width/height/whatever of two shapes and get a bool for whether or not they're colliding.

The reason I want something like this is because I'm using Box2d, which has collision detection, but it only works if objects are moving naturally. I have a sensor that constantly gets teleported to the mouse, and there's no way to tell if things collide with that sensor using Box2d collision events!

Edit: Didn't know MouseJoint existed, the problem's now resolved. Thanks!

For things like that you can use queries instead of a body. I use World:queryBoundingBox() and then, if it needs to be accurate, use Fixture:testPoint() on each fixture that I get.

You can try HC.

If you set the velocity of the object you teleport right after you do, you might be luckier with that.

Also, maybe a mousejoint helps?
