ios - 如何在 swift 中使用 JSTileMap

Question

你能在 swift 中使用 JSTileMap 吗？如果可以，你如何使用它。如果我不能快速使用它，或者它有太多错误，那么还有什么我可以用于 .tmx map 的。请注意，我正在使用 sprite 工具包

Answer 1

可以的，我昨天才开始用，还没发现问题!首先导入 JSTileMap 文件和 libz.dylib 框架。然后添加具有以下导入的桥接 header :

#import "JSTileMap.h"
#import "LFCGzipUtility.h"

接下来只需进入您的 SKScene 文件并创建一个 tileMap 变量，如下所示:

var tileMap = JSTileMap(named: "tileMap.tmx")

我发现定位有点棘手，所以我也添加了它。

self.anchorPoint = CGPoint(x: 0, y: 0)
self.position = CGPoint(x: 0, y: 0) //Change the scenes anchor point to the bottom left and position it correctly


let rect = tileMap.calculateAccumulatedFrame() //This is not necessarily needed but returns the CGRect actually used by the tileMap, not just the space it could take up. You may want to use it later
tileMap.position = CGPoint(x: 0, y: 0) //Position in the bottom left
addChild(tileMap) //Add to the scene

下面是我用来创建一层 SKSpriteNodes 的代码:

func addFloor() {
        for var a = 0; a < Int(tileMap.mapSize.width); a++ { //Go through every point across the tile map
            for var b = 0; b < Int(tileMap.mapSize.height); b++ { //Go through every point up the tile map
                let layerInfo:TMXLayerInfo = tileMap.layers.firstObject as TMXLayerInfo //Get the first layer (you may want to pick another layer if you don't want to use the first one on the tile map)
                let point = CGPoint(x: a, y: b) //Create a point with a and b
                let gid = layerInfo.layer.tileGidAt(layerInfo.layer.pointForCoord(point)) //The gID is the ID of the tile. They start at 1 up the the amount of tiles in your tile set.

                if gid == 2 || gid == 9 || gid == 8{ //My gIDs for the floor were 2, 9 and 8 so I checked for those values
                    let node = layerInfo.layer.tileAtCoord(point) //I fetched a node at that point created by JSTileMap
                    node.physicsBody = SKPhysicsBody(rectangleOfSize: node.frame.size) //I added a physics body
                    node.physicsBody?.dynamic = false

 //You now have a physics body on your floor tiles! :)
                }
            }
        }
    }
