T2D isometric tile rendering and picking in C++ (nxIsoTileMap, nxIsoTileLayer)

This is a quick and dirty version to allow interleaved tile rendering, picking and editing
for isometric views.

Note that this is simply an early experimental version to share some of the
stuff I've done, so lets not hear anything about what it doesn't do, right? ;p

I will add some other stuff I've been working on as I get the time, in the meantime
See following url for my ongoing plan on my experiments with this.

[update] 2005/10/18
Added map loading as fxTileMap2D does not call createTileLayer() that is overridden by calls new fxTileLayer2d()
directly. Just created a copy of loadFromStream() to fix it without touching underlaying T2D stuff.

[/update]

the updated code you can find here

[update] 2006/03/07

I am busy updating it for T2D beta 1.1 with new naming convention and new additions and changes
like serialization, comma delimeted (normal) parameters instead of one string, etc.

Once I have updated the code to 1.1 I will update this resource descriptions to reflect that as well.

Will hopefully have it up soon.

NOTE: I will not be doing any new dev on this as it was just an example. If/when I do get back to iso stuff
in the future I will create an entirely new iso sub system from the ground up and not based on t2dTileMap.

[/update]

=========================

Just extract the zip file into your T2D engine source dir and rebuild. The code is seperated
into a sub dir (NX) so won't overwrite anything.

See source for descriptions and explanations, etc.

Usage example:

%map = new nxIsoTileMap(){ scenegraph = t2dSceneGraph };

That's it ;p

=========================

To use in tile editor:

in "~/tileeditor/client/editorScreen.cs"

around line 16 (under "editor state global vars"):

add:

$loadIsoMap = false;

around line 432 [ function loadMap() ]:

replace

// Create new Tile-Map.
	$editorTileMap = new fxTileMap2D(){ scenegraph = tileEditorSceneGraph2D; };

with

// Create new Tile-Map.
	if( $loadIsoMap )
        	$editorTileMap = new nxIsoTileMap(){ scenegraph = tileEditorSceneGraph2D; }
	else
		$editorTileMap = new fxTileMap2D(){ scenegraph = tileEditorSceneGraph2D; };

do the same around line 737 [ function initializeTileMap() ]

replace

// Create new Tile-Map.
	$editorTileMap = new fxTileMap2D(){ scenegraph = tileEditorSceneGraph2D; };

with

// Create new Tile-Map.
	if( $loadIsoMap )
        	$editorTileMap = new nxIsoTileMap(){ scenegraph = tileEditorSceneGraph2D; }
	else
		$editorTileMap = new fxTileMap2D(){ scenegraph = tileEditorSceneGraph2D; };

finally, in "~tileeditor/client/newTileDlg.gui"


around line 191 (after last control) add:

new GuiRadioCtrl(IsoMapRB) {
         profile = "GuiRadioProfile";
         horizSizing = "right";
         vertSizing = "bottom";
         position = "112 134";
         extent = "92 26";
         minExtent = "8 2";
         visible = "1";
         text = "Isometric map";
         groupNum = "-1";
         buttonType = "ToggleButton";
      };

Usage:

Run T2D, start the tile editor, create a new tile map (make sure 'isometric map' is checked) and
start placing isometric tiles ;p

Remember to use a 2 to 1 ratio for tile width/height to get the right view angle as well as
2 to 1 ratio for your rows/columns as you move by half in Y so will need double the tiles
to cover the same space.
