Hi, in my game i have created a collision function, in this game multiple eggs fall from the sky and when they collide with the “ground” i want them to disappear … the problem is that when the first contacts the ground it disappears but the rest of them don’t… can you pls help me?

COLLISON CODE:

 function onGroundCollision( self, event )

   if ( event.phase == “began” ) then

        if(self.myName == “egg”) then 

            if(event.other.myName == “ground”) then

                audio.play(sound3)

                

                    self.isVisible = false

                    self:removeSelf()

                end

                    

            end

          

       

        end

    

  

end

 

FRAMES CODE:

this is the code that drops multiple eggs

 

ocal function onFrame(event)    

frameCounter = frameCounter + 1

if(frameCounter % 40 == 0 and eggCount > 0) then 

        eggCount = eggCount - 1

        local egg = display.newImage(“egg.png”)

        egg.x = math.random(0, 310)

        egg.y = 0

        egg.rotation = math.random(0, 360)

        physics.addBody(egg, {density = 2.0, friction = 1.5, bounce=0.01})

Hi Abraham,
Where do you set the “myName” property on the eggs? Or on the ground object?

Hi Brent

I set “myName” property on the egg in the “createScene” section … e.g 

egg = display.newImage(“egg.png”)

     egg.x = 180

     egg.y = 80

     egg.rotation = 10

     physics.addBody(egg, {density = 2.0, friction = 1.5, bounce=0.0})

     egg.myName = “egg”

     screenGroup:insert( egg )

OK, I see. You need to apply this property to each egg that you generate in the loop. Each “local” egg is a new display object, so it has its own properties that it doesn’t inherit from anywhere else. Thus, you need to add this to every new egg. That should do the trick. :slight_smile:
