So, here is what’s going on i can launch the game on simulator but it looks like nothing is working as i expected . when objects collide it should display text ir remove 2 objects and start again . please help

–hide setStatusBar

Try this.

When you declare your display objects, give them another property called myName…like this.

cake.myName = “cake”

happy.myName = “happy”

Then for your collision, use this.

local function onGlobalCollision( event )

    if ( event.phase == “began” ) then

        if (event.object1.myName == “happy” and event.object2.myName== “cake”) then

             local text = display.newText(“you just hit the cake”, display.contentCenterX, display.contentCenterY, native.systemFontBold,                  50)

       

    else

–

  happy:removeSelf()

  cake:removeSelf()

  local text = display.newText(“Game Over. Try Again”, display.contentCenterX, display.contentCenterY, native.systemFontBold, 50)

  timer.performWithDelay(3000, function() text:removeSelf(); text = nil; cake = nil end)

  timer.performWithDelay(4000, function()

         --reset things after the collision

        createHappy();

        createCake();

        angry.x = 880

        angry.y = 600

        angry2.x = 830

        angry2.y = 520

        

       end)

     end

    end

  

end

Runtime:addEventListener(“collision”, onGlobalCollision)

It’s a start. There’s more you’ll need to work out, specifically with timers, but this will get you started.

#3

Also, you called a global onCollision function before the localized one…get rid of it.
