Adding weight to an object?

I have a sprite that I gave the physics of a sphere to.

local instance = sprite.newSprite(set);  
instance.x = display.contentWidth/70   
physics.addBody(instance, {bounce = 0.2, friction = .1, radius = 30})  
instance.name = "sprite"  

I’m wondering how I can add weight to only the bottom part of it. I want the weight to be so heavy that it always is resting on that point.

Any help would be awesome.
Thanks,

To just add weight to bottom you’d need to add another body part to it - it’s a whole object so any weight right now would effect the entire body. [import]uid: 52491 topic_id: 12798 reply_id: 47164[/import]

I agree with peach. You may also want to set the density to something high ( like 5 or 10) to the object you add so it’s heavier. [import]uid: 13780 topic_id: 12798 reply_id: 47190[/import]
