Sorry your browser is not supported!

Okay well i just quickly went back to my pong game and i wanted to add a scoring system this is usally easy well i first checked it in the while loop and it worked fine. here is the code that i tested in the while loop
i changed the scoring system to this
then this is my while loop now
but when the ball touches the side it deletes like it supposed to score goes up once and then goes don exatly same time i hope i made sense of this.

This should probably be

Also, move the dbCLS() and dbSync() back out to the LoopGDK() loop (you currently have dbSync() commented out - uncomment it and put the dbCLS() after that) and remove them from the player.score()

You probably don't want to dbDeleteSprite(ballID) and should instead use dbHideSprite(ballID). I'm assuming that ball.reset() re-creates the ballID sprite? If so, have it position the sprite where you want it and re-show the sprite. Creating resources is slow - and doing it every frame will kill your performance.

Beyond that, without seeing the rest of the code, there really isn't much more that I can suggest.

Sorry the code button is not working i dont know if it just me or what but i tried to fix it twice both failed most likly it is me but any ways...
