Hidden objects still have physics bodies active

#1

Hi guys

Hoping someone can help me, I have run a few tests and the problem I have is that when I make an object hidden isVisible=false, the object is removed from the screen but its physics body is still active and still registering collisions?

Any ideas please?

Remove the physics body when you’re not using it, and add the physics body back when you need it again:

physics.removeBody( image );
…
physics.addBody( image, physicsData );

I think a better solution is simply to set the body’s [lua]isBodyActive[/lua] to false (http://docs.coronalabs.com/api/type/Body/isBodyActive.html). This has the effect of removing it from the physics simulation. You would also set the [lua]isVisible[/lua] property to false, as you already have, so that the image associated with the body doesn’t appear on screen.

Hope this helps.
