Inserting merged tileset into FlxAtlas

starry-abyss

Hi!
I was playing with FlxAtlas class, and I wanted to add FlxTileFrames object to the atlas. I get the object from FlxTileFrames.combineTileFrames. To prevent tile tearing I use border argument set to (2, 2) (in dev branch of HaxeFlixel).

I'm aware of a function FlxAtlas.addNodeWithSpacesAndBorders, that could replace the FlxTileFrames.combineTileFrames, but I want all tilesets to be placed so they are one whole FlxTileFrames that I can use with FlxTilemap (first tile in every tileset goes after the last in previous tileset).

What can be done in that regard?

I think you can do it this way:

var border:FlxPoint = new FlxPoint(2, 2);
var tileSize:FlxPoint = new FlxPoint(tileWidth, tileHeight);
var tileSpacing:FlxPoint = new FlxPoint(0, 0);
var combinedTileFrames:FlxTileFrames = FlxTileFrames.combineTileFrames(tileframes, tileSpacing, border);

var node:FlxNode = atlas.addNode(combinedTileFrames.parent.bitmap, "combined tiles");
var combinedTileSize:FlxPoint = new FlxPoint(tileSize.x + border.x, tileSize.y + border.y);
var combinedTileFramesFromAtlas:FlxTileFrames = node.getTileFrames(combinedTileSize, tileSpacing, border); // this is the frame collection you want to use

@teormech Thanks, it seems to work if I add some multipliers to penultimate line like this:

var combinedTileSize:FlxPoint = new FlxPoint(tileSize.x + border.x * 2, tileSize.y + border.y * 2);

Need to eliminate some double-caching now, will post again if something goes wrong!

Oh, i forgot about x2.
If you don't need combinedTileFrames anymore then you can just call FlxG.bitmap.remove(combinedTileFrames.parent); and set combinedTileFrames to null

@teormech OK, I believe this is what I do for elements in array tileframes too?

if you won't use them anymore - then yes
