SKSpriteNode替换为SKTexture

Question

我的问题是，当我玩我的游戏，我失去了我的生命，即使敌人没有触及我的性格，但飞非常接近他。我知道问题是，我的性格的透明空间是与敌人的透明空间接触的。

我想按照SKPhysicsBody文档中的建议做。如何使用我的当前代码来实现这一点？

func madEnemy() {

    let randomNumber = Int.random(in: 1..<6)

    let enemy = SKSpriteNode(imageNamed: "enemy\(randomNumber)")

    enemy.position = CGPoint(
        x: cameraRect.maxX + enemy.size.width/2,
        y: CGFloat.random(
            min: cameraRect.minY + enemy.size.height/2,
            max: cameraRect.maxY - enemy.size.height/2))
    enemy.zPosition = 50
    enemy.name = "enemy"
    addChild(enemy)

    let actionMove =
        SKAction.moveBy(x: -(size.width + enemy.size.width), y: 0, duration: 2.0)
    let actionRemove = SKAction.removeFromParent()
    enemy.run(SKAction.sequence([actionMove, actionRemove]))
}

您只需要先从图像中创建一个SKTexture对象，然后使用该纹理创建一个SKSpriteNode，以便使用纹理来调整SKPhysicsBody或节点的大小。

func madEnemy() {

    let randomNumber = Int.random(in: 1..<6)

    let enemyTexture = SKTexture(imageNamed: "enemy\(randomNumber)")
    let enemy = SKSpriteNode(texture: enemyTexture)
    enemy.physicsBody = SKPhysicsBody(texture: enemyTexture, size: CGSize(width: enemy.size.width, height: enemy.size.height))

    enemy.position = CGPoint(
        x: cameraRect.maxX + enemy.size.width/2,
        y: CGFloat.random(
            min: cameraRect.minY + enemy.size.height/2,
            max: cameraRect.maxY - enemy.size.height/2))
    enemy.zPosition = 50
    enemy.name = "enemy"
    addChild(enemy)

    let actionMove =
        SKAction.moveBy(x: -(size.width + enemy.size.width), y: 0, duration: 2.0)
    let actionRemove = SKAction.removeFromParent()
    enemy.run(SKAction.sequence([actionMove, actionRemove]))
}
