swift - 在另一个中添加 SKShapeNode

Question

我想在另一个正方形里画一个正方形；但我无法以正确的方式定位第二个。根据第一个平方坐标进行定位可以做什么？

    var tileBackground = SKShapeNode(rectOfSize: CGSize(width: screenWidth, height: screenWidth))
    tileBackground.name = "tileBackground"
    tileBackground.fillColor = SKColor.whiteColor()
    tileBackground.position = CGPoint(x: frame.midX, y: frame.midY);
    self.addChild(tileBackground)

    var tile = SKShapeNode(rectOfSize: CGSize(width: tileSize, height: tileSize))
    tile.name = "tile1"
    tile.fillColor = SKColor.redColor()
    tile.position = CGPointMake(100,100)
    tileBackground.addChild(tile)

Answer 1

您应该使用 SKSpriteNode 代替。这样您就可以轻松添加它，而无需手动设置位置。因为在 SKSpriteNode 中，中心始终是节点的中心:

var tileBackground = SKSpriteNode(color: UIColor.whiteColor(), size: CGSizeMake(width: screenWidth, height: screenWidth))
tileBackground.name = "tileBackground"
tileBackground.position = CGPoint(x: frame.midX, y: frame.midY);
self.addChild(tileBackground)


var tile = SKSpriteNode(color: UIColor.redColor(), size: CGSize(width: tileSize, height: tileSize))
tile.name = "tile1"
tileBackground.addChild(tile)
