问题
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
}
回答1:
The documentation states
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].
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
the texture will appear. You can also set fillColor with a different color to colorize the texture:
circle.fillColor = .blue
