使用 SKSpritenodes 和纹理 [英] Working with SKSpritenodes and textures

问题描述

我正在尝试编写允许用户将Ghost"更改为不同图像的功能.

I am trying to program in feature that allows the user to change the "Ghost" to a different image.

这是我的代码:

    Ghost = SKSpriteNode(imageNamed: "Ghost17")
    Ghost.size = CGSize(width: 50, height: 50)
    Ghost.position = CGPoint(x: self.frame.width / 2 - Ghost.frame.width, y: self.frame.height / 2)
    Ghost.physicsBody = SKPhysicsBody(circleOfRadius: Ghost.frame.height / 1.4)
    Ghost.physicsBody?.categoryBitMask = PhysicsCatagory.Ghost
    Ghost.physicsBody?.collisionBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Wall
    Ghost.physicsBody?.contactTestBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Wall | PhysicsCatagory.Score
    Ghost.physicsBody?.affectedByGravity = false
    Ghost.physicsBody?.isDynamic = true
    Ghost.zPosition = 2

    if defaults1.integer(forKey: "Sphere") == 2 {
        Ghost = SKSpriteNode(imageNamed: "Ghost13")
    }
    if defaults1.integer(forKey: "Sphere") == nil! {
        Ghost = SKSpriteNode(imageNamed: "Ghost2")
    }

    self.addChild(Ghost)

我使用 UserDefaults 在 vi​​ewContollers 之间发送信息.

I am using UserDefaults to send the information between the viewContollers.

当我单击将 defaults1 设置为 2 的按钮时，会弹出新图像，但它的行为与应有的不同.我不知道如何解决这个问题，如果您需要更多信息，请询问.

When i click on the button that sets the defaults1 to 2 the new image pops up but it doesn't behave like it should. Im not sure how to fix this, if you need anymore info please ask.

推荐答案

当改变纹理时，尝试使用这个:

When changing the texture, try using this:

Ghost.texture = SKTexture(imageNamed: "Ghost13")

而不是:

Ghost = SKSpriteNode(imageNamed: "Ghost13")

这只会改变节点的纹理属性，而不是重新初始化它.您可能会遇到这些问题，因为您在重新初始化节点时正在重置它.

This only changes the texture property of the node rather than reinitializing it. You may be encountering the issues because you're resetting the node when you reinitialize it.
