Is anyone able to troubleshoot this glitch I have with my game?

[Y2JayC]

Is anyone able to troubleshoot the glitch I have when the ball hits the left side of the screen in my game. This doesn't happen on the right side so I'm not too sure why this is happening. Here is my code:

var xDirection:Number = 10;

var yDirection:Number = -10;

var targetX:Number = player_mc.x;

var easing:Number = 7;

var playerScore:Number;

function resetBallPosition():void

{

xDirection = 10;

yDirection = -10;

ball_mc.x = 2

ball_mc.y = 11

}

function checkHitLocation(player:MovieClip):void

{

var hitPercent:Number;

var ballPosition:Number = ball_mc.x - player_mc.x;

hitPercent = (ballPosition / player_mc.width);

xDirection = hitPercent * 30;

yDirection *= 1.025;

}

function initializeGame(event:MouseEvent):void

{

playerScore = 0;

showScore();

showStart();

player_mc.addEventListener(Event.ENTER_FRAME, movePlayer);

ball_mc.addEventListener(Event.ENTER_FRAME, moveBall);

bg_mc.removeEventListener(MouseEvent.CLICK, initializeGame);

}

function endGame():void

{

player_mc.removeEventListener(Event.ENTER_FRAME, movePlayer);

ball_mc.removeEventListener(Event.ENTER_FRAME, moveBall);

bg_mc.addEventListener(MouseEvent.CLICK, initializeGame);

text_mc.text = 'CLICK TO PLAY AGAIN';

text_mc.visible = true

start_mc.visible = false;

}

function moveBall(event:Event):void

{

if(ball_mc.x <= 0)

{

xDirection *= -1;

text_mc.visible = false;

start_mc.visible = false;

}

else if(ball_mc.x >= stage.stageWidth - ball_mc.width)

{

xDirection *= -1;

text_mc.visible = false;

start_mc.visible = false;

}

if(ball_mc.hitTestObject(player_mc))

{

yDirection *= -1;

ball_mc.y = player_mc.y - ball_mc.height - player_mc.height/2;

checkHitLocation(player_mc);

playerScore ++;

showScore();

text_mc.visible = false;

start_mc.visible = false;

}

if(ball_mc.y <= 0)

{

yDirection *= -1;

//resetBallPosition();

text_mc.visible = false

start_mc.visible = false;

}

else if(ball_mc.y >= stage.stageHeight - ball_mc.height)

{

endGame();

resetBallPosition();

showScore();

}

ball_mc.x += xDirection;

ball_mc.y += yDirection;

}

function movePlayer(event:Event):void

{

if(this.mouseX <= player_mc.width/2)

{

targetX = 0;

start_mc.visible = false;

}

else if(this.mouseX >= stage.stageWidth - player_mc.width/2)

{

targetX = stage.stageWidth - player_mc.width;

start_mc.visible = false;

}

else

{

targetX = this.mouseX - player_mc.width/2;

start_mc.visible = false;

}

player_mc.x += (targetX - player_mc.x) / easing;

}

function showScore():void

{

score_mc.text = "Score: " + playerScore;

start_mc.visible = false;

}

function showStart():void

{

start_mc.text = 'CLICK SCREEN TO START';

start_mc.visible = true;

}

showStart();

bg_mc.addEventListener(MouseEvent.CLICK, initializeGame);

You are testing the right side of the screen with:

ball_mc.x >= stage.stageWidth - ball_mc.width

but the left side with:

if(ball_mc.x <= 0)

Try:

if(ball_mc.x <= ball_mc.width)

If either side makes the ball reflect too soon, try using ball_mc.width/2.

Use the trace command to see what the value of xDirection is when it is in the conditional at the <= 0 end of things.  It appears that it is constantly resetting between -1 and +1 when it gets there.  Maybe you can get around that by forcing it to move away from the limit when it makes the switch... as in....

if(ball_mc.x <= 0)

{

xDirection *= -1;

ball_mc.x = 1;

text_mc.visible = false;

start_mc.visible = false;

}
