Thread: Game score increasing rapidly....

Not sure if anyone can help me, or if ive even posted in the correct place


Im building just a simple game with a ball and a paddle at the bottom, everytime the ball hits the paddle you get 1 point. But the minute the score is increasing by 7-8 points everytime you hit the paddle. Im not sure where im going wrong could someone help.

Code:

#import "GameViewController.h"
#import "KeepyUppiesViewController.h"
#import "GameOverViewController.h"

@implementation GameViewController

@synthesize scoreLabel;
@synthesize score;
@synthesize ball;
@synthesize paddle;
@synthesize livesLabel;
@synthesize messageLabel;

- (void)startPlaying {
	if (!lives) {
		lives = 3;
		score = 0;
		
	}
	scoreLabel.text = [NSString stringWithFormat:@"%d", score];
	livesLabel.text = [NSString stringWithFormat:@"%d", lives];
	ball.center = CGPointMake(159, 239);
	ballMovement = CGPointMake(4,4);
	// choose whether the ball moves left to right or right to left
	if (arc4random() % 100 < 50)
		ballMovement.x = -ballMovement.x;
	messageLabel.hidden = YES;
	isPlaying = YES;
	/*
	[self initialiseTimer];
	*/
	[self performSelector:@selector(initialiseTimer) withObject:nil afterDelay:2.0];
	
}
- (void)pauseGame {
	[theTimer invalidate];
	theTimer = nil;
	
}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
	
	[self startPlaying];

	 }
- (void)initialiseTimer {
	
	
	if (theTimer == nil) {
		
		float theInterval = 1.0f/50.0f;
		
		theTimer = [NSTimer scheduledTimerWithTimeInterval:theInterval target:self
												  selector:@selector(animateBall:) userInfo:nil repeats:YES];
		
	}
}

- (void)animateBall:(NSTimer *)theTimer {
	
	ball.center = CGPointMake(ball.center.x+ballMovement.x, ball.center.y+ballMovement.y);
	
	BOOL paddleCollision = ball.center.y >= paddle.center.y - 16 &&
	
	ball.center.y <= paddle.center.y + 16 &&
	ball.center.x > paddle.center.x - 32 &&
	ball.center.x < paddle.center.x + 32;

	if (ball.center.y > 444) {

		}
		messageLabel.hidden = NO;
	}

I havent been programming long so be easy on me

What is this?

This is a C++ forum therefore it serves that Game programming in the context of this board means Game Programming in C/C++.

This is not an Objective C board and your question will be best answered elsewhere.
