方法.removeFromParent()不会删除精灵。怎么了?
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
guard touches.first != nil else {
return
}
let myShot = SKSpriteNode()
let myShotAnimation = SKAction.repeatActionForever(SKAction.animateWithTextures(myShotTexture, timePerFrame: 0.01))
myShot.size = CGSizeMake(200, 200)
myShot.anchorPoint = CGPoint(x: 0.5, y: 0.5)
myShot.zPosition = 0
sprite!.addChild(myShot)
let myShotAction = SKAction.group([SKAction.scaleBy(0.1, duration: 0.5), myShotAnimation])
let actionRemove = SKAction.removeFromParent()
myShot.runAction (SKAction.sequence([myShotAction, actionRemove]))
}
带有动画的精灵“myShot”不会消失
最佳答案
仅仅是因为actionRemove
永远不会被调用。
启动时:
myShot.runAction (SKAction.sequence([myShotAction, actionRemove]))
依次运行
myShotAction
SKAction和完成后的actionRemove
。但是,如果第一个SKAction是一个永无休止的动作(SKAction.repeatActionForever),则actionRemove
将永远不会调用。关于ios - SKAction.removeFromParent不要使用SKAction.repeatActionForever删除 Sprite ,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37513830/
