我有一个游戏,我的节点在屏幕中间,如果我按住屏幕的左侧,节点将向左移动,如果我按住屏幕的右侧,节点将向右移动。我尝试了一切,但似乎无法让它工作。谢谢!(我有一些代码,但它没有做我想让它做的事情。如果你想看到它以及它有什么不好的地方把它放上去。
编辑代码:
var location = touch.locationInNode(self)
if location.x < self.size.width/2 {
// left code
let moveTOLeft = SKAction.moveByX(-300, y: 0, duration: 0.6)
hero.runAction(moveTOLeft)
}
else {
// right code
let moveTORight = SKAction.moveByX(300, y: 0, duration: 0.6)
hero.runAction(moveTORight)
}
在每次更新中,你需要检查一下你的触摸位置,以确定你希望角色移动的方向。
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
var touch = touches.first as! UITouch
var point = touch.locationInView(self)
touchXPosition = point.x
touchingScreen = true
}
override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {
super.touchesEnded(touches, withEvent: event)
touchingScreen = false
}
override func update(currentTime: CFTimeInterval) {
if touchingScreen {
if touchXPosition > CGRectGetMidX(self.frame) {
// move character to the right.
}
else {
// move character to the left.
}
}
else { // if no touches.
// move character back to middle of screen. Or just do nothing.
}
}
