使用 Swift 在 Sprite Kit 中构建棋盘游戏? [英] Building a chess board game in Sprite Kit using Swift?

问题描述

在使用 Swift 的 Sprite Kit 中，我正在尝试构建一个国际象棋棋盘(实际上是一个类似国际象棋的棋盘/瓷砖网格).那么总的来说，我应该如何创建一个方形网格板?

In Sprite Kit using Swift, I am trying to build a chess board (in actuality, a chess-like board / tile grid). So in general, how should I go about creating a square grid board?

我已经做了很多研究，并通过多维数组研究了一些类似国际象棋棋盘的高级概念的例子，但它仍然没有真正解释如何在 Sprite Kit 中直观地表示它，更重要的是，如何将视觉表示映射到多维数组中的字母+数字表示...

I have done a lot of research and have studied some examples of the high-level concept of chess-like boards through multi-dimensional arrays but it still doesn't really explain how to VISUALLY represent it in Sprite Kit and more importantly, how to map the visual representation to the letter+number representation in a multi-dimensional array...

有什么想法吗?

如果有人能在上述问题中至少回答一点/部分，将不胜感激！非常感谢您！

If anyone could answer at least one point/part in the above question, it would be greatly appreciated! Big thank you in advanced!

推荐答案

在 SpriteKit 中绘制棋盘的一种方法是在适当的位置添加交替的白色和黑色精灵节点.这是一个如何做到这一点的示例.

One way to draw a chessboard in SpriteKit is to add alternating white and black sprite nodes at the appropriate locations. Here's an example of how to do that.

    override func didMoveToView(view: SKView) {
        self.scaleMode = .ResizeFill

        // Draw the board
        drawBoard()
        // Add a game piece to the board
        if let square = squareWithName("b7") {
            let gamePiece = SKSpriteNode(imageNamed: "Spaceship")
            gamePiece.size = CGSizeMake(24, 24)
            square.addChild(gamePiece)
        }
        if let square = squareWithName("e3") {
            let gamePiece = SKSpriteNode(imageNamed: "Spaceship")
            gamePiece.size = CGSizeMake(24, 24)
            square.addChild(gamePiece)
        }
    }

此方法绘制棋盘.

    func drawBoard() {
        // Board parameters
        let numRows = 8
        let numCols = 8
        let squareSize = CGSizeMake(32, 32)
        let xOffset:CGFloat = 50
        let yOffset:CGFloat = 50
        // Column characters
        let alphas:String = "abcdefgh"
        // Used to alternate between white and black squares
        var toggle:Bool = false
        for row in 0...numRows-1 {
            for col in 0...numCols-1 {
                // Letter for this column
                let colChar = Array(alphas)[col]
                // Determine the color of square
                let color = toggle ? SKColor.whiteColor() : SKColor.blackColor()
                let square = SKSpriteNode(color: color, size: squareSize)
                square.position = CGPointMake(CGFloat(col) * squareSize.width + xOffset,
                    CGFloat(row) * squareSize.height + yOffset)
                // Set sprite's name (e.g., a8, c5, d1)
                square.name = "(colChar)(8-row)"
                self.addChild(square)
                toggle = !toggle
            }
            toggle = !toggle
        }
    }

该方法返回指定名称的方形节点

This method returns the square node with the specified name

    func squareWithName(name:String) -> SKSpriteNode? {
        let square:SKSpriteNode? = self.childNodeWithName(name) as SKSpriteNode?
        return square
    }
