Time for action – adding the egg object

Imagine a world, full of falling eggs. It's not entirely too realistic, but in this game, we're creating this element. At least, we'll be making sure that both gravity and real-world physics will be applied. To add the egg object, perform the following steps:

1. Create a new local function called eggDrop():

       local eggDrop = function()

2. Add in the egg display object properties:

         local egg = display.newImageRect( "egg.png", 26, 30 )
         egg.x = 240 + mRand( 120 ); egg.y = -100
         egg.isHit = false
         physics.addBody( egg, "dynamic",{ density=eggDensity, bounce=0, friction=0.5, shape=eggShape } )
         egg.isFixedRotation = true
         gameGroup:insert( egg )

3. Add in the postCollision event for the egg display object:

         egg.postCollision = onEggCollision
         egg:addEventListener( "postCollision", egg )
       end

   

What just happened?

We have set the egg value for x with 240 + mRand( 120 ). The mRand function is equal to math.random, which will allow...
