Similar to the SpriteKit Featured Game "Adventure" from WWDC, I am try to load my background image via tiles. I have created a Texture Atlas that contains 6,300 "tiles" that are each 100x100 pixels in size. The complete background image is a total of 30,000x2048 (for retina displays). The idea is that the background will move from right to left (side-scroller). The first column and the last column match so that they seem continuous. When the application runs, it loads my initial loading screen and title images and spikes to 54MB in my memory tab with a CPU usage of 16% . This stays the same as

Is it possible to use the SceneEditor to layout & create a complex Subclass of SKSpriteNode, load that information and create a custom object in your scene based on the sks file? My scenario is that I have a popup dialogs (which are nothing more than subclasses of SKSpriteNodes) with a lot of children on the dialog. I was hoping to lay it out in the Scene editor similar to how I lay out an SKScene, and then present it in my scene when needed. I realize that I could just create this object in my GameScene.sks file, but find that those can get easily cluttered, and thought it might be a nicer

This question already has answers here : Horizontally mirror a SKSpriteNode texture (4 answers) Closed 5 years ago . Is there a way to create a SKSpriteNode and pass it an image name, but have it reflect the image horizontally? You mean you want to flip the image? node.xScale = node.xScale * -1; or node.yScale = node.yScale * -1; 来源： https://stackoverflow.com/questions/21008886/ios-sprite-kit-how-to-reflect-a-sprite-horizontally

I have a player in my game, it has two states flying, falling. Each of them has an image: player_flying, player_falling correspondingly. I am also using a physical bodies to detect collision. It is completely normally functioning when I use one texture. But when I am trying to use both in different conditions using different textures, it shows me an error in the log. I am trying it like that: if (self.player.physicsBody.velocity.dy > 30) { self.player.texture = [SKTexture textureWithImageNamed:@"player_flying"]; self.player.physicsBody = [SKPhysicsBody bodyWithTexture:self.player.texture size

I use the following piece of code to generate SKNodes periodically. Is there a way to make the period of generation of these SKNodes random. Specifically, how do I make the "delayFish" in the following code an action with a random delay? [self removeActionForKey:@"fishSpawn"]; SKAction* spawnFish = [SKAction performSelector:@selector(spawnLittleFishes) onTarget:self]; SKAction* delayFish = [SKAction waitForDuration:3.0/_moving.speed]; SKAction* spawnThenDelayFish = [SKAction sequence:@[spawnFish, delayFish]]; SKAction* spawnThenDelayFishForever = [SKAction repeatActionForever
