While learning and playing around with Swift and Spritekit i run into an issue: I can´t seem to create many SKShapeNodes at Runtime. I am trying to fill the Screen with "random" Triangles (The green Triangle on top is just a "dummy" Triangle moving from the left to the right so i get to see the FPS) These brown-ish Triangles are SKShapeNodes created like this: func createTwoFloorTrianglesAtLocation(xPos:CGFloat, yPos:CGFloat, width:CGFloat, height:CGFloat, orientation:Bool) -> [SKShapeNode] { let path1 = UIBezierPath() let path2 = UIBezierPath() if orientation { path1.move(to: CGPoint(x: xPos, y: yPos)) path1.addLine(to: CGPoint(x: xPos, y: yPos + height)) path1.addLine(to: CGPoint(x: xPos + width, y: yPos)) path2.move(to: CGPoint(x: xPos + width, y: yPos)) path2.addLine(to: CGPoint(x: xPos + width, y: yPos + height)) path2.addLine(to: CGPoint(x: xPos, y: yPos + height)) } else { path1.move(to: CGPoint(x: xPos, y: yPos)) path1.addLine(to: CGPoint(x: xPos + width, y: yPos + height)) path1.addLine(to: CGPoint(x: xPos, y: yPos + height)) path2.move(to: CGPoint(x: xPos + width, y: yPos)) path2.addLine(to: CGPoint(x: xPos, y: yPos)) path2.addLine(to: CGPoint(x: xPos + width, y: yPos + height)) } let triangle1 = SKShapeNode(path: path1.cgPath) triangle1.fillColor = groundColors[GKRandomSource.sharedRandom().nextInt(upperBound: groundColors.count)]! triangle1.name = "colorSprite" triangle1.lineWidth = 0.0 let triangle2 = SKShapeNode(path: path2.cgPath) triangle2.fillColor = groundColors[GKRandomSource.sharedRandom().nextInt(upperBound: groundColors.count)]! triangle2.name = "colorSprite" triangle2.lineWidth = 0.0 return [triangle1, triangle2] } I add these Triangles calling #addChild(SKNode) to the GameScene. These Triangles don´t move or anything, they are supposed to disappear later in the Game by "drawing lines" above them. The Problem is that i get very bad FPS and a high CPU-Usage as well as a high Power-Usage in both the XCode-Simulator and on a real Device (iPhone 13 Pro Max, too). If i reduce the Amount of Triangles it gets better, but i´d like to not do that. Is there any way to fix this issue? I also read online (https://stackoverflow.com/questions/23461966/create-an-sktexture-from-an-skshapenode) that some use SKSpriteNode instead of SKShapeNode. But if use the following code to "convert" my ShapeNodes to SpriteNodes before adding them as a Child to the Scene, i see the Node-Counter in the Bottom left is also around 1000ish but there are no Rectangles rendered. func addNodesToParent(_ stuff:[SKShapeNode]) { for n in stuff { addChild(SKSpriteNode(texture: self.view?.texture(from: n))) //addChild(n) } } I hope someone has an idea that i can try. Thanks in advance, Greetings, Nico
