如何让敌人生成更快

Question

override func update(currentTime: CFTimeInterval) {
    if currentTime - self.lastEnemyAdded > 1 { //my lastEnemyAdded is "var lastEnemyAdded : NSTimeInterval = 0.0"
        self.lastEnemyAdded = currentTime + 0.5 //how can i make this -0.1 as the game go longer or if the player reach a certain score
        self.addEnemy() //can someone help me please
    } 
}

Answer 1

您可以通过将此添加到您的 didMoveToView 方法中来实现：

runAction(SKAction.repeatActionForever(SKAction.sequence([SKAction.runBlock(addEnemy), SKAction.waitForDuration(1.0)])))

您可以根据需要更改 waitForDuration 并在每 1 秒后将 addEnemy() 函数调用到此代码中。

希望这会有所帮助。
