I'm not sure about box 2d (what is that?), but here is how I move a sprite with the mouse in AGK...

SetSpritePosition(spriteID, GetPointerX(), GetPointerY())

box2d is the physics part of agk , i`ve been trying to use the mousejoint and mousejoint target commands , i`ve managed to get a physics sprite to move around with mouse i now need to make it disconnect from the joint and carry on being affected with physics , i think the joint would have to be deleted .

gonna try it now thanks anyways.

Oh, the physics section of the docs.
I have not tried playing with the joints yets.
Interesting reading though.
I might play with this tomorrow and see what I can come up with.

Yeah, just from reading the docs for a few minutes, I think you are right.
Deleting the mousejoint should do the trick.

Thanks and good luck

We need a good tutorial on Box2d.
Do you know if there is anything generic that explores all the various commands with examples?

@bjadams the box2d examples and docs are c++ and they are a far cry from how they are used in agk , in agk all the difficulty and setup are wrapped away .

What you can do is download the latest box2d from http://box2d.org/ , and compile the testbed there are many examples of how things work but as i said the commands are c++ and more difficult.
