Disable collision?

Is there a way to disable the collision between physics bodies?
i.e. if I have multiple physics bodies moving around on the screen, how do I make them not collide with each other (I just want them to flow right through each other)

For physics bodies that you don’t want to collide with any other objects, yet still register hit events (like a bullet for example), then you can use the body.isSensor physics property.

However, if what you want to do is have an object collide with some other objects but not others, then what you need to do is set up a collision filter. Another forum member set up a great tutorial/explanation of this here: http://developer.anscamobile.com/forum/2010/10/25/collision-filters-helper-chart
