How to use JSTileMap in fast

Question

Can you use JSTileMap in swift, and if so, how do you use it. If I cannot use it in swift or if it is too buggy, is there anything else I can use for .tmx maps. Notice i'm using a sprite kit

Answer 1

Yes, you can, I just started using it yesterday and have not found a problem! Start by importing the JSTileMap files and the libz.dylib framework. Then add the bridge header with the following imports:

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

Next, just go into the SKScene file and create the tileMap variable, as shown below:

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

I found that positioning is a bit complicated, so add this too.

 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 

EDIT

below is the code that I used to create the SKSpriteNodes floor:

 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! :) } } } }
