var lightTexture = SKTexture(imageNamed: "green light.png")
var lightTexture2 = SKTexture(imageNamed: "red light.png")
var animationLight = SKAction.animateWithTextures([lightTexture, lightTexture2], timePerFrame: 3)
var changeLight = SKAction.repeatActionForever(animationLight)
light = SKSpriteNode(texture: lightTexture)
light.position = CGPointMake(CGRectGetMidX(self.frame), 650)
light.runAction(changeLight)
self.addChild(light)
我想让动画以随机时间间隔(1秒到3秒之间的随机时间)设置。然后,如果在红灯亮起时触摸屏幕,我想要出现一个游戏符号。提前谢谢。

您需要使用的是SKAction.waitForDuration(_:withRange :)
或更具体地说:
let lightTexture = SKTexture(imageNamed: "green light.png")
let lightTexture2 = SKTexture(imageNamed: "red light.png")
let animateLights = SKAction.sequence([
SKAction.waitForDuration(2.0, withRange: 2.0),
SKAction.animateWithTextures([lightTexture, lightTexture2], timePerFrame: 3)
])
let changeLight = SKAction.repeatActionForever(animateLights)
let light = SKSpriteNode(texture: lightTexture)
light.position = CGPointMake(400, 650)
light.runAction(changeLight)
self.addChild(light)
根据文档,您的动画将持续2秒+/- 1秒。
另请注意,我冒昧地将“var”变量更改为“let”常量,因为它们没有被更改。
