我的SKTexture大小不适合我的SKSpriteNode

let texture = SKTexture(imageNamed: "myImage")
texture.filteringMode = .nearest // 设置纹理过滤模式
let sprite = SKSpriteNode(texture: texture)
sprite.size = CGSize(width: 100, height: texture.size().height * (100 / texture.size().width))

let texture = SKTexture(imageNamed: "myImage")
let sprite = SKSpriteNode(texture: texture)
sprite.xScale = 0.5 // 水平缩放比例
sprite.yScale = 0.5 // 垂直缩放比例

let texture = SKTexture(imageNamed: "myImage")
let sprite = SKSpriteNode(texture: texture)
sprite.size = CGSize(width: 200, height: 200) // 设置精灵节点的大小

import SpriteKit

class MyScene: SKScene {
    override func didMove(to view: SKView) {
        let texture = SKTexture(imageNamed: "myImage")
        texture.filteringMode = .nearest
        
        let sprite = SKSpriteNode(texture: texture)
        sprite.position = CGPoint(x: frame.midX, y: frame.midY)
        
        // 调整精灵节点的大小
        let desiredSize = CGSize(width: 150, height: 150)
        sprite.size = desiredSize
        
        addChild(sprite)
    }
}
