我正在使用 SpriteKit 制作游戏,其中我有一个节点使用此 SKAction 序列从屏幕的左侧到右侧反复来回移动:
func move(){
let recursive = SKAction.sequence([
SKAction.moveByX(frame.size.width/2.8, y: 0, duration: NSTimeInterval(4),
SKAction.moveByX(-frame.size.width/2.8, y: 0, duration: NSTimeInterval(4),
SKAction.runBlock({self.move()})])
doc.runAction(recursive, withKey: "move")
}
该节点是一个 SKTexture,我正在使用一个名为 WalkRight 的图集。我想要做的是,当 SKAction.moveByX(-frame.size.width/2.8, y: 0, duration: NSTimeInterval(4) 运行时,我想使用 .xscale 来旋转我的 walkRight 图像。我无法弄清楚如何将此代码合并到我的 SKAction 序列中。
下面是我添加地图集的代码,以防需要回答问题。
//In class
var docWalkingFrames: [SKTexture]!
// general runAction method to make doc walk.
func walkingDoc() {
doc.runAction(SKAction.repeatActionForever(SKAction.animateWithTextures(docWalkingFrames,timePerFrame: 0.3,resize: false,restore: true)),withKey:"walkingInPlaceDoc")
}
//In didMoveToView
//doc animation walk right
let docAnimatedAtlas = SKTextureAtlas(named: "WalkRight")
var walkFrames = [SKTexture]()
let numImages = docAnimatedAtlas.textureNames.count
for var i=1; i<=numImages; i++ {
let docTextureName = "docRight\(i)"
walkFrames.append(docAnimatedAtlas.textureNamed(docTextureName))
}
docWalkingFrames = walkFrames
let firstFrame = docWalkingFrames[0]
doc = SKSpriteNode(texture: firstFrame)
doc.position = CGPoint(x:self.frame.size.width/3.1, y:self.frame.size.height/2)
doc.size = CGSize(width: 220, height: 470)
doc.zPosition = 2
addChild(doc)
walkingDoc()
