Swift SpriteKit：永远分开运行两个SKActions

Question

我是Swift和SpriteKit的新手，我遇到了一个小问题。我想每秒产生一次敌人，同时每帧稍微移动玩家一次。所以我尝试创建两个单独的SKActions。这是我的代码：

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

runAction(SKAction.repeatActionForever(
    SKAction.runBlock(
        movePlayer
    )
))

但是当我执行上述操作时，都不会发生任何操作。我该如何解决这个问题？

你需要写self.addEnemy()＆amp; self.movePlayer()

就眼睛来说，我会像这样编写代码：

var waitE = SKAction.waitForDuration(1)
var runE = SKAction.runBlock{
self.addEnemy()
}

var runP = SKAction.runBlock{
    self.movePlayer()
} 

var repeatMovingPlayer = SKAction.repeatActionForever(runP)
var EnemySeqence = SKAction.seqence([waitE, runE])
var repeatAddingEnemy = SKAction.repeatActionForever(EnemySeqence)

self.runAction(repeatAddingEnemy)
self.runAction(repeatMovingPlayer)
