Collision with physics (need help)

Hello,

I have been using this collision code when a ball touches line. When the ball touches line, there is another line "line2" that pops up in a different position. The ball later SHOULD touch line2 and perform a collision. The problem is every time i try to add physics to line2, the simulator crashes. Can i not add physics to collision objects? Any help please?

Thanks.

ball.myName = "ball"
line.myName = "line"
 
ball:addEventListener("collision",ball)
 
function ball:collision (event)
        if event.other.myName == "line" then
 
local line2=display.newImageRect("line.png",400,10)
line2.x=display.contentWidth/2
line2.y=display.contentHeight/1.3
line2.rotation=30
 
physics.addBody(line2, "static", {friction=0.3,bounce=0.3}) 
 
        end
end

Since i can not see the rest of your code I have no clue if this is going to work but here is a stab in the dark..

The first thing that pops out at me is

local line2=display.newImageRect("line.png",400,10)

being defined in your collision handler.

instead define the variable out side ( above your handler )

local line2

then inside your function you can assign it.

line2=display.newImageRect("line.png",400,10)

LUA is a top down language and it's logic process may be messing you up ( it's gotten me countless times ).
