I am creating a pong game and i want the other paddle to move by it self Why isnt this code working

+ Code Snippet

if(dbSpriteY(ballID) > dbSpriteY(plr2) && dbSpriteCollision(plr2,10)== 0)
	{
	dbMoveSprite(plr2,3);
	}
	else
	if(dbSpriteY(ballID) < dbSpriteY(plr2) && dbSpriteCollision(plr2,13)== 0)
	{
	dbMoveSprite(plr2,- 3 );
	}
	else
	if(dbSpriteY(ballID) == dbSpriteY(plr2)&& dbSpriteCollision(plr2,10)== 0 && dbSpriteCollision(plr2,13)== 0 )
	{
	dbMoveSprite(plr2,0);
	}

okay so the ball bounces off the paddle and the player is trying to get points by making the other player miss. i got every thing running fine i just want the other paddle to move by the computer and btw it can on move verically(up and down) so i was wondering y the paddle isnt moving by it self

Hi, could you please provide a little more info on what doesn't work like does it compile and run? What does the paddle do instead of moving as you intend it to?

Ok, I have a clearer picture now. The first thing I would like to suggest is to move the paddle via a y value instead of the dbMoveSprite command. So it would be like:

+ Code Snippet

if(bally > paddley) {
   paddley += 3;
}
if(bally < paddley) {
   paddely -= 3;
}

Then later draw the sprite like this

+ Code Snippet

dbSprite( sprite_num, paddlex, paddley, image )

As for not moving the paddle when the ball isn't in the screen you could have a boolean ball_in_screen and add that to your if statements.
