Hi,

For playing audio – background music or sound effects – using Corona SDK, do the following,

1. Load the audio stream (background music or sound effects)

 backgroundMusic = audio.loadStream("bgm.mp3") 

2. Play the audio

backgroundMusicChannel = audio.play( backgroundMusic, { channel=1, loops=-1, fadein=5000 }  )  

It will play the background music on channel 1, loop infinitely, and fadein over 5 seconds. Loop 1 will set it to play once!

In order to receive memory warning in Corona, use the following chunk of code,

local function memoryWarningCheck ( event )
    print( "Memory Warning ! Memory is leaking somewhere! " )
end
Runtime:addEventListener( "memoryWarning", memoryWarningCheck )

In order to get the elapsed time after the application launch in Corona, use the following lines of code,

function elapsedTimeCalc( event )
  print ("Time elapsed since app launch---"..event.time/1000 )
end

Runtime:addEventListener("enterFrame", elapsedTimeCalc)

Thus we will get the elapsed time after the app launch in milliseconds.

Hi,

For destroying physics bodies in Corona SDK, use any of the following methods.

urBody:removeSelf()

OR

urBody.parent:remove( urBody )

Note :
While Box2D objects will be safely retained until the end of the current world step, their Lua references will be deleted immediately. Therefore, be careful not to accidentally delete the same Lua object more than once. This situation could occur when deleting objects involved in collisions, which can potentially have many event phases before the collision is fully resolved. The solution is simple:

local function onCollision( self, event )
        if ( event.phase == "began" ) then

                -- Check if body still exists before removing!
                if ( urBody ) then
                        urBody:removeSelf()
                        urBody = nil
                end

        end
end
