What is SKSpinLockSync in Sprite Kit and how do I fix it

Question

I am receiving a bug report with the following stack trace and I have no idea what the problem is. I\'ve seen suggestions that this could be caused by having an emitter\'s

Answer 1

If using SKEmitterNode and create more than 1 at the same time (close around the same time), my game still crashed. I had to manually preload (create and add emitter to scene), by then I was able to prevent the crashing I had to let the particle effect to be created and added to the scene and let it run its action. I then set the particle alpha to 0, to hide it. By then I was By Disappointment, I preloaded everything.

Using SKEmitterNode and getEmitter method above, I still getting crashes when I create more than 1 emitter around the same time. I solve this by creating one of the particle on the start, add it to the scene, and set its alpha to 0. This is a jacky way and it blows, but it works and doesn't crash.

Example:

@implementation MyGameScene

- (instancetype)initWithSize:(CGSize)size
{
    if(self = [super initWithSize:size]){
        HitEmitter *emitter = [HitEmitter particle]; // class method use getEmitter method
        [self addChild:emitter];
        [emitter setName:@"temp"];
        [emitter setAlpha:0];

        // add a second timer to remove it.
        [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(removeEmitter) userInfo:nil repeats:NO];
    } return self;
}
