iOS working code: CGRect textureSize = CGRectMake(0, 0, 488, 650); CGImageRef backgroundCGImage = [UIImage imageNamed:@”background.png”].CGImage; UIGraphicsBeginImageContext(self.level.worldSize); // use WithOptions to set scale for retina display CGContextRef context = UIGraphicsGetCurrentContext(); CGContextDrawTiledImage(context, textureSize, backgroundCGImage); UIImage *tiledBackground = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); SKTexture *backgroundTexture = [SKTexture textureWithCGImage:tiledBackground.CGImage]; SKSpriteNode *backgroundNode = [SKSpriteNode spriteNodeWithTexture:backgroundTexture]; [self addChild:backgroundNode];

Each TextureAtlas is 60K As a file maybe. But that’s not memory usage. To calculate memory usage of an image file, take the file’s dimensions and multiply them with color bit depth (usually 32 bits = 4 bytes). For example a 4096×4096 texture uses 16 MB of texture memory (but it may be much less … Read more
