SKAction.wait 导致调用错误中的额外参数

Question

我正在尝试对文本标签进行动画处理和编码，但是使用 SKAction.wait(:) 函数会导致调用错误中的额外参数。这是我的代码。我没有其他错误，我的其他 SKAction 函数工作正常：

import SpriteKit
import GameplayKit

class GameScene: SKScene {

    private var label : SKLabelNode?


    override func didMove(to view: SKView) {

        // Get label node from scene and store it for use later
        self.label = self.childNode(withName: "//helloLabel") as? SKLabelNode
        if let label = self.label {
            label.alpha = 0.0
            label.run(SKAction.fadeIn(withDuration: 2.0))

            var animateList = SKAction.sequence(SKAction.fadeIn(withDuration: 1.0), SKAction.wait(forDuration: 2.0), SKAction.fadeOut(withDuration: 1.0))

        }
    }
}

Answer 1

SKAction.sequence 接受一个数组作为参数。所以你的声明应该是这样的

var animateList = SKAction.sequence([SKAction.fadeIn(withDuration: 1.0), SKAction.wait(forDuration: 2.0), SKAction.fadeOut(withDuration: 1.0)])
