Collision detection for complex physics objects. <<SOLVED>>

Hey.

I have a skateboarder and board set up as follows

function setPlayer()  
  
player1 = display.newRect (0, 0, 30, 30)  
skaterShape = { -15,-10, 15,-10, 15,15, -15,15 }  
skaterShape.myName = "skater"  
boardShape = { -15, -15, 15, -15, 15, -10, -15, -10 }  
boardShape.myName = "board"  
player1.x = \_W / 2 + 150  
player1.y = 41 + player1.contentHeight / 2 -- was 35  
player1:setFillColor(0, 0, 255)  
player1.myName = "player1"  
playergroup:insert(player1)  
  
physics.addBody( player1, "dynamic",  
 { density=1, friction=0, bounce=0, shape=skaterShape },  
 { density=1, friction=0, bounce=0, shape=boardShape }  
)  
  
player1.collision = onLocalCollision  
player1:addEventListener( "collision", player1 )  
  
end

I need to detect which “shape” skater or board has collided with the ground.

I already have it set up so that “player1” collides perfectly with the terrain, and thought it would be a simple matter of using something like

boardShape.myName = "board"

in the local collision event.

I’ve tried adding an event listener to skater and board respectively, but it gave a “nil” error, probably because skater and board are tables rather than display objects.

Can anyone help, I’m sure it’s something really simple.

Thanks in advance.

*** EDIT ***

I used

event.selfElement == 2

to sort this out, in case anyone else has the same problem (and doesn’t read the documentation properly :slight_smile: [import]uid: 67933 topic_id: 16156 reply_id: 316156[/import]
