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];

I havent been programming long so be easy on me ;)
