Hello Tom.

I'm just testing your library and works pretty well!

My problem maybe has nothing to do with your library. I have added a node which the camera keeps on the center all the time. This node moves at constant velocity and does well when its moving at a low speed. But when I increase it, some vertical lines appear between the tiles. Do you know how to solve it? Thanks!

edit: btw It only happens when moving horizontally, and i'm using an iPad to test it (60 framerate)

Hi Tom

Are you aware that the "gid" being returned by gid = node.tileData.id
is 1 higher than the tile ID shown in "Tiled" ?

Note : JSTileMap had same issue - so I suspect it may be the way Tiled is exporting the data

Is this something you can correct ?

Hi Tom

Currently you can only get objects by id, position, name or type.
Would be good to be able to iterate through the Objects in the object layer like this -

    let objectGroup = tileMap.getObjectGroup(name: "Object Layer 1")
    for object in objectGroup {
        //process object
    }

However, this produces the error as objectGroup does not conform to protocol SequenceType
Would be good if you get the object group to conform to sequence type protocol
Note : this saves you from looping through the entire grid space looking for objects.

Thanks

Hi, m8

just wanted to see if you have already tried this on Xcode8 and Swift 3.
I am getting an error on loading the map, but can't figure it out why.

Hello Tom,
thank you for your great work

To use your library in a OSX app, I have modified your "SKTileMap" by adding #if !os(OSX) ... #end in the "SKTilmapLayer.swift" for the following functions:

     #if !os(OSX)
    /* Returns a tile at a given touch position. A custom offset can also be used. */
    func tileAtTouchPosition(touch: UITouch, offset: CGPoint = CGPointZero) -> SKTilemapTile? {

        if let coord = coordAtTouchPosition(touch, offset: offset, round: true) {
            return tileAtCoord(coord)
        }

        return nil
    }
    #endif

AND:

    #if !os(OSX)
  func coordAtTouchPosition(touch: UITouch, offset: CGPoint = CGPointZero, round: Bool = true) -> CGPoint? {
        return coordAtPosition(touch.locationInNode(self), offset: offset, round: round)
    }
  #endif

Are you planning to make the library compatible to OSX apps as well?
Thank you for your consideration

By default - Tiled coordinate system puts (0,0) in the top left
By default - SpriteKit coordinate system puts (0,0) in the bottom left

This is resulting in Y values that start at 0 and reduce to -screen size
To correct this - I believe you can add Screen Height to the y position when tiles are loaded.

In SKTilemapLayer - fun tilePositionAtCoord

change

    case .Orthogonal:

        position = CGPoint(x: x * Int(tileSize.width) + Int(tileAnchorPoint.x * tileSize.width),
                           y: y * Int(-tileSize.height) - Int(tileSize.height - tileAnchorPoint.y * tileSize.height))

to

    case .Orthogonal:

        let tmpMapSize = Int(tilemap.size.height * tileSize.height)
        let tmpYpos = y * Int(-tileSize.height) - Int(tileSize.height - tileAnchorPoint.y * tileSize.height)

        position = CGPoint(x: x * Int(tileSize.width) + Int(tileAnchorPoint.x * tileSize.width),
                           y: tmpMapSize + tmpYpos)

Testing seems to produce the correct results with Y values now starting at 0 in the bottom of the screen
Additionally this change did not seem to produce any other side effects (but will require more testing)

Let me know what you think

Hi Tom

Great work so far on this - it looks and works really well.
Do you have any plans to support cropping ?
I have tile maps that are 50 * 500 - which creates a lot of objects and requires some form of cropping to keep frame rates at a reasonable level (Note : JSTileMap has similar built in)

Tile clipping actually causes worsens the performance when more tiles are drawn to the scene.
Going to work on a fix as this shouldn't be the case.

Hello Tom,
brilliant job! I was looking for a library like yours for a long time.

I was just wondering if you are planning to have an option that allows the TileMap to be aligned to the bottom left corner of the screen. Currently, I see that the map has been centred in the middle of the screen.
Thank you
Daniele

Hi Tom

I noticed the loading time for a large map is slow using SKTileMap.
As a test I loaded the identical map in two apps, one using SKTileMap, the other JSTileMap (https://github.com/slycrel/JSTileMap)

The results can be seen below in the debug log outputs.

SKTileMap loading time for 50* 500 Map (68 seconds)

08:38:09:817 -- GameScene.swift -- didMoveToView
08:39:17:463 -- GameScene.swift -- didMoveToView -- SETUP FINISHED

JSTileMap loading time for 50 * 500 Map (0.5 secs)

08:53:45:306 -- GameScene.swift -- didMoveToView
2016-04-22 08:53:45.567 Swifty[1691:1096158] Layer Tile Layer 1 has zPosition -60.000000
2016-04-22 08:53:45.621 Swifty[1691:1096158] Layer Tile Layer 2 has zPosition -40.000000
08:53:45:788 -- GameScene.swift -- didMoveToView -- SETUP FINISHED

Happy to provide more information if required
