Make spawning object solid

Games
#1

How can I make my spawning orb solid, so if my orbs touch each other they move away from each other.
This is my spawning codes
[lua]local function spawnOrb()
if( spawnTrue == true )then
local randomPos = math.random ( 0, 480 )
orb = display.newImage( “orb.png” )
orb.x = 100
orb.y = -100
orb.myName = “orb”
physics.addBody(orb , “dynamic”, {isSensor = true, radius = 15})
localGroup:insert( orb ) --PEACH: Adds new orbs to localGroup for use with Director
end
end
orbTimer = timer.performWithDelay( 200, spawnOrb, 0 )

The orbs physics bodies wont react with each other because you have their .isSensor property set to true, setting this to false will have their bodies react to each other. [import]uid: 40731 topic_id: 33729 reply_id: 134090[/import]
