In above program i m trying to detect collision between customer and the customer End point circle …but not able to do this… can anyone suggest me why it not fire the collision method… [import]uid: 42177 topic_id: 8114 reply_id: 308114[/import]

Because all your bodies are static.

In this situation it is (I find) always good to build a proof of concept to test your problem. In this case, I put together the following code. Try it and you’ll find that changing the “static” for the ‘a’ body to “dynamic” causes collision events to be fired.

[lua]local physics = require(“physics”)
physics.start()

local a = display.newCircle( 100, 100, 25 )
local b = display.newCircle( 100, 300, 25 )

physics.addBody( a, “static”, { radius=25 } )
physics.addBody( b, “static”, { radius=25 } )

function c( event )
print(‘runtime’, event)
end

function a:collision( event )
print(‘body’, event)
end

Runtime:addEventListener( “collision”, c )
a:addEventListener( “collision”, a )

transition.to( a, { y=a.y+300, time=5000 } )[/lua]
