Getting Stuck

[Tyler29294]

I am making a game pretty much like canabalt but no where near as cool becuase I'm much newer. So I am using UIKit and am getting stuck. Literally. Here's my code

- (void)gameLogic:(NSTimer *)gameTimer {
	
	blockyVelocity.y += gravity.y;
	
	if (!(CGRectIntersectsRect(groundAnimation.frame, blocky.frame))){
		if(!(blocky.center.y + 25 == groundAnimation.center.y)){
			blocky.center = CGPointMake(blocky.center.x, blocky.center.y + blockyVelocity.y);
		}
	}
}

- (void)jump{
	blockyVelocity.y += -kBlockJump;
}

- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event {
	[self jump];
}

I can "jump" anytime before blocky hits the ground but once it does it get's stuck. Any help is appreciated!

Never mind! Turns out I wasn't calling the code to let the block fall. Scraped that code and started over. Ened up creating this instead.

- (void)gameLogic:(NSTimer *)gameTimer {
	
	if (!blockyOnGround)
		blockyVelocity.y += gravity.y;
	
	if (CGRectIntersectsRect(blocky.frame, groundAnimation.frame)) {
		if (blocky.center.y <= groundAnimation.center.y){
			blockyOnGround = YES;
		}
	}
	else {
		blockyOnGround = NO;
		blocky.center = CGPointMake(blocky.center.x, blocky.center.y + blockyVelocity.y);

	}

}

- (void)jump{
	
	if (blockyOnGround) {
		blockyVelocity = CGPointMake(0, 0);
		blockyVelocity.y = - kBlockJump;

		blocky.center = CGPointMake(blocky.center.x, blocky.center.y + blockyVelocity.y);
		blockyOnGround = NO;
	}
		
}
