我正在开发一个游戏，当按下按钮时我的玩家会移动，所以我制作了相机的按钮子项。但是，当我的相机移动时，按钮会出现在应有的位置，但是当我再次按下时，没有任何反应。这是一些关于相机和按钮的代码。
override func didMove(to view: SKView) {
physicsWorld.contactDelegate = self
enumerateChildNodes(withName: "//*", using: { node, _ in
if let eventListenerNode = node as? EventListenerNode {
eventListenerNode.didMoveToScene()
}
})
world = childNode(withName: "World")!
player = (world.childNode(withName: "player") as! Player)
spikes = world.childNode(withName: "spikes") as! SKSpriteNode
spikes.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: spikes.size.width/2, height: spikes.size.height/2))
spikes.physicsBody?.categoryBitMask = PhysicsCategory.Spikes
spikes.physicsBody?.isDynamic = false
self.addChild(cameraNode)
camera = cameraNode
cameraNode.position = CGPoint(x: 0 , y: 0)
cameraToMove = cameraNode.position.y - player.position.y
setupCamera()
left = SKSpriteNode(imageNamed: "leftButton")
right = SKSpriteNode(imageNamed: "rightButton")
jump = SKSpriteNode(imageNamed: "upButton")
jump.size.width /= 2
jump.size.height /= 2
left.position = CGPoint(x: -self.size.width/2 + left.size.width, y: -self.size.height/2 + left.size.height)
right.position = CGPoint(x: left.position.x + 2 * right.size.width, y:(camera?.position.y)! - self.size.height/2 + left.size.height)
jump.position = CGPoint(x: self.frame.width/2 - jump.size.width, y:(camera?.position.y)! - self.size.height/2 + left.size.height)
cameraNode.addChild(left)
cameraNode.addChild(right)
cameraNode.addChild(jump)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch = touches.first
let location:CGPoint = (touch?.location(in: self))!
if left.contains(location){
move(forTheKey: "left")
print("left")
}
else if right.contains(location){
move(forTheKey: "right")
print("right")
}
else if jump.contains(location){
player.physicsBody?.applyImpulse(CGVector(dx: 0, dy: 240))
}else{
print(location)
}
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch = touches.first
let location:CGPoint = (touch?.location(in: self))!
if left.contains(location){
player.physicsBody?.velocity = CGVector(dx: 0, dy: 0)
print("left removed")
}
else if right.contains(location){
player.physicsBody?.velocity = CGVector(dx: 0, dy: 0)
print("right removed")
}
else if jump.contains(location){
print("jump removed")
}else{
print("else")
print(location)
print(left.position)
print(convert(left.position, from: cameraNode))
print(convert(left.position, to: cameraNode))
print(camera?.position.y)
player.physicsBody?.velocity.dx = 0
}
}
正如你所看到的，我有很多打印来检查左按钮的位置。开始时 y 位置为 -577。相机移动后，按钮出现在它应该在 -450 的位置。但不能按它，因为它的位置仍然在-577。我还尝试通过将位置转换为相机来更新其位置，但没有奏效。如果有人可以提供帮助，我将不胜感激。
