在不使用UIKit的情况下如何处理SKSpriteNode上的点击

class GameScene: SKScene {
    let spriteNode = SKSpriteNode(color: .red, size: CGSize(width: 100, height: 100))
    
    override func didMove(to view: SKView) {
        addChild(spriteNode)
        isUserInteractionEnabled = true
    }
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touch = touches.first else { return }
        
        let touchLocation = touch.location(in: self)
        
        if spriteNode.contains(touchLocation) {
            // 在目标节点范围内点击
            spriteNode.color = .blue
        }
    }
}
