physics radius not working

Getting Started Newbie Questions
#1

I’ve been away from Corona for about 5 months and it’s really developed over that time… I feel a bit like a new user and now I having a new user problem. In the past I could define a round physics shape around an object using “radius”. Since I upgraded my corona build this is no longer working… its always a square equal to the size of the image. What am I doing wrong? Thanks!

projectile = display.newImage(“stone.png”)
physics.addBody( projectile, dynamic, {density = 2, radius=20}) [import]uid: 129205 topic_id: 31799 reply_id: 331799[/import]

Never mind… the problem was that I forgot my “” around the physics type… this confused the physics engine. Doh!

Should have been:

projectile = display.newImage(“stone.png”)
physics.addBody( projectile, “dynamic”, {density = 2, radius=20}) [import]uid: 129205 topic_id: 31799 reply_id: 126945[/import]
