SKShapeNode filltexture()不显示图像 [英] SKShapeNode filltexture() does not display image

问题描述

我想创建一个内容为图像(.png)的圆，并基于SKShapeNode类引用，我认为可以使用SKShapeNode.filltexture()函数将纹理设置为图像.但是，当我运行下面的代码时，我得到了圆圈，但是我尝试加载的猫黑"的图像没有显示.我检查了我的Image.Assets是否具有正确名称的图像，因此出现了其他情况. 有任何想法吗?我在下面附加了输出:

I want to create a circle that whose content is an image (.png), and based on the SKShapeNode class reference, I thought that I could use SKShapeNode.filltexture() function to set the texture to the image. But when i run the code below, I get the circle, but the image of the "cat-black" I am trying to load doesn't show. I checked that my Image.Assets have the image with the correct name, so something else is up. Any ideas? I attached the output below:

 func newCircle(photo:String, position:CGPoint) -> SKShapeNode {

    let circle = SKShapeNode.init(circleOfRadius: 27)
    circle.fillTexture = SKTexture.init(image: UIImage(named: "cat-black")!)
    circle.strokeColor = UIColor.greenColor()
    circle.lineWidth = 4
    circle.name = "aggroNode"
    circle.position = position
    return circle

}

文档说明

默认值为nil.如果指定了填充纹理，则fillColor属性将被忽略，并且填充部分 形状节点是使用纹理而不是[强调添加]渲染的.

The default value is nil. If a fill texture is specified, the fillColor property is ignored and the filled portion of the shape node is rendered using the texture instead [emphasis added].

这表明必须填充形状，否则纹理将不可见；因此，如果您将形状的填充颜色设置为

This suggests that the shape must be filled or the texture will not be visible; therefore, if you set the shape's fill color with

circle.fillColor = .white

纹理将会出现.您还可以将fillColor设置为其他颜色以使纹理着色:

the texture will appear. You can also set fillColor with a different color to colorize the texture:

circle.fillColor = .blue
