我正在使用SpriteKit进行游戏,我有一个节点,使用此SKAction序列重复从屏幕的左侧到右侧来回移动:
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")
}
节点是SKTexture,我正在使用名为WalkRight的图集。我想要做的是,当运行SKAction.moveByX(-frame.size.width / 2.8,y:0,duration:NSTimeInterval(4)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。
以下是我添加地图集的代码,以防需要回答这个问题。
//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()
答案 0 :(得分:0)
使用自定义阻止操作并在该操作中,运行检查以查看它是向左还是向右,然后根据节点调整节点的xScale
。 xScale -1
和xScale 1
是您将使用的值。
