Question

我目前正在开发游戏的一部分，其中涉及移动瓷砖，可以推动其他瓷砖，基本上就像那些拼图板丢失，你需要重建图像。

问题：有没有办法，不使用box2d和碰撞检测来让瓷砖正确移动？

这与我之前提出的问题有关：

我问的是因为物理引擎将瓷砖留在了整个地方。

可能会丢失多个部分（与此图片不同，只有一个部分）

它归结为更大的“董事会”中的递归功能。谢谢你的意见。大多数情况下只需要知道这很容易。

func moveTile(tile:Tile, amount:CGFloat, direction:Direction) -> CGFloat {
    var checkLocation:CGPoint = tile.position
    var spaceBetween:CGFloat = 0
    switch direction {
    case .North:
        checkLocation.y += amount + (tileSize.height / 2)
    case .South :
        checkLocation.y -= amount + (tileSize.height / 2)
    case .East:
        checkLocation.x += amount + (tileSize.width / 2)
    case .West:
        checkLocation.x -= amount + (tileSize.width / 2)
    }
    var maxAmount = amount
    if !boundingEdgeRect.contains(checkLocation) {
        switch direction {
        case .North:
            maxAmount -= checkLocation.y - boundingEdgeRect.height - boundingEdgeRect.origin.y
        case .South :
            maxAmount -= boundingEdgeRect.origin.y - checkLocation.y
        case .East:
            maxAmount -= checkLocation.x - boundingEdgeRect.width - boundingEdgeRect.origin.x
        case .West:
            maxAmount -= boundingEdgeRect.origin.x - checkLocation.x
        }
    } else {
        let nodes = self.nodesAtPoint(checkLocation)
        for node in nodes {
            if let nextTile = node as? Tile {
                switch direction {
                case .North:
                    spaceBetween = nextTile.position.y - tile.position.y - tileSize.height
                case .South :
                    spaceBetween = tile.position.y - nextTile.position.y - tileSize.height
                case .East:
                    spaceBetween = nextTile.position.x - tile.position.x - tileSize.width
                case .West:
                    spaceBetween = tile.position.x - nextTile.position.x - tileSize.width
                }
                let tileAmount = moveTile(nextTile, amount:amount - spaceBetween, direction:direction) + spaceBetween
                if tileAmount < maxAmount {
                    maxAmount = tileAmount
                }
            }
        }
    }
    switch direction {
    case .North:
        tile.position.y += maxAmount
    case .South :
        tile.position.y -= maxAmount
    case .East:
        tile.position.x += maxAmount
    case .West:
        tile.position.x -= maxAmount
    }
    return maxAmount
}

瓷砖是中心锚定的，位置相对于板，也是中心锚定。

在没有物理引擎的情况下移动瓷砖
