Box2d no gravity issue

in a box2d simulation, when I have gravity == 0,0 sometime and randomly an object whic I cna move around doesn t react with the other floating objects.
I am using UpdateBody to move the object around but I can see that in the Box2d workshop pdf it says:

“This node is fully spreadable, so you can set multiple bodiesat the same time upon conditions.
Putting a body to sleep will also Set all velocity components to 0.
Setting new position is generally not recommended, as it can break the simulation. More efficient
methods for moving objects will be presented later.”

So that may be the problem. But it doesn t say which one is the best way to do it, maybe MouseJoint ? Is there an example I can see ?


OK got it!
the issue seems to be gone now …
