Swift (SpriteKit) 中出现了 Sprite 物理但没有视觉显示

Question

我设置了精灵的物理体、zPosition、颜色、大小等，但它不会在视觉上出现。（它具有我精灵中最高的 zPosition，是的，我确实导入了 SpriteKit）

let wall = SKSpriteNode()
wall.physicsBody?.velocity = CGVector(dx: 0, dy: 0)
//Takes screen size / width to make each piece one/(value set by "maze" at top) of the screen
let width: CGFloat = (UIScreen.main.bounds.width) / CGFloat(mazeSize)
let height: CGFloat = (UIScreen.main.bounds.height - 134) / CGFloat(mazeSize) //subtract so there's extra room on top+bottom of screen
wall.color = UIColor(ciColor: .black)
wall.isHidden = false
wall.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: width, height: height))
wall.physicsBody?.restitution = 0
wall.physicsBody?.friction = 0
wall.physicsBody?.isDynamic = false
wall.zPosition = 4
//sets up x+y location based on row count and which row this is on
//locations (ONLY positive)
let xLoc: CGFloat = ((UIScreen.main.bounds.width) / CGFloat((mazeSize/2))) * CGFloat(i/mazeSize)
let yLoc: CGFloat = ((UIScreen.main.bounds.height - 134) / CGFloat(mazeSize/2)) * CGFloat(i/mazeSize)
if((i/mazeSize) > (mazeSize/2)){ //if positive on x
    wall.position.x = xLoc
}
else{ //if negative on x
    wall.position.x = -xLoc
}
if(i > ((mazeSize^2)/2)){ //if positive on y
    wall.position.x = yLoc
}
else{ //if negative on y
    wall.position.y = yLoc
}

我正在使用它在迷宫中设置墙壁（是的，我知道 x+y 位置是错误的，但它们仍然 "appear" 聚集在中间），但只有这些节点的物理特性出现。有没有办法让这些黑墙出现？

精灵节点的几何形状和物理体的几何形状不必相关，在这种情况下，您已经制作了一个矩形物理体和基本上是一个空的精灵节点。试试像

let wall = SKSpriteNode(color: .black, size: CGSize(width: 100, height: 100)

或使用 SKSpriteNode(texture:) 初始值设定项。
