	Me and My Shadow Theme File Description
	=======================================

	(draft)

	The theme file contains:

	name=<theme name>

	1 block subnode
	---------------

	block(<block name>){...} //subnode specifies the block's appearance

	In this subnode:

	editorPicture(<file name>,<x>,<y>,<w>,<h>) //specifies the picture shows in editor

	-1.1 blockState subnode
	+1.1 state/characterState/blockState subnode
	----------------------

	+NOTE: blockState and characterState are for backwards compatibility, use state instead.
	+
	blockState(<state name>){...} //subnode specifies the appearance of each state of the block

	the state name: for example "default" or "activated", detailed information to be announced...

	optional attributes:

	oneTimeAnimation=<length>,<next state> //if this state is one-time animation only

	1.1.1 object subnode
	--------------------

	object{...} //subnode specifies (multiple) objects to display in each state

	optional attributes:

	animation=<length>,<loop point> //if object has looped animation
	oneTimeAnimation=<length>,<end point>
	invisibleAtRunTime=1 //if this object is invisible when playing game
	invisibleAtDesignTime=1 //if this object is invisible when editing the map

	optional nodes specifies object to display:

	1.1.1.1 picture subnode
	-----------------------

	picture(<file name>,<x>,<y>,<w>,<h>)

	1.1.1.2 optionalPicture subnode
	-------------------------------

	optionalPicture(<file name>,<x>,<y>,<w>,<h>,<probability>)

	1.1.1.3 editorPicture subnode
	-----------------------------

	editorPicture(<file name>,<x>,<y>,<w>,<h>)

	If this subnode is set, the picture will be used in the level editor.

	1.1.1.4 offset subnode
	----------------------

	offset(<x>,<y>)

	1.1.1.5 pictureAnimation subnode
	--------------------------------

	pictureAnimation(<file name>){
	point(<x>,<y>,<w>,<h>)
	point(<x>,<y>,<w>,<h>,<frame count>,<display time of each frame>)
	...
	}

	1.1.1.6 offsetAnimation subnode
	-------------------------------

	offsetAnimation{
	point(<x>,<y>)
	point(<x>,<y>,<frame count>,<display time of each frame>)
	...
	}

	2 background subnode
	--------------------

	Specifies the background of level.
	There can be multiple background subnodes.
	Each subnode is a layer of background.

	Syntax:

	background(<file name>){
	srcSize=<x>,<y>,<w>,<h> //Specifies the source size and offset of picture (optional, default value=image size)
	destSize=<x>,<y>,<w>,<h> //Specifies the destination size and offset of picture (optional, default value=source size)
	repeat=<repeat x>,<repeat y> //Repeat in x,y direction? (0 or 1) (optional, default value=1,1)
	speed=<speed x>,<speed y> //Specifies the moving speed (pixel/frame, a real number) (optional, default=0,0)
	cameraSpeed=<x>,<y> //The speed of following camera (a real number, typically in 0-1) (optional, default=0,0)
	-}
	\ No newline at end of file
	+}
	+
	+3 character subnode
	+-------------------
	+
	+Specifies the appearance of player and shadow.
	+
	+Syntax:
	+
	+character(Player){
	+ ...
	+}
	+
	+or
	+
	+character(Shadow){
	+ ...
	+}
	+
	+The other format is the same as the block subnode.
	+
	+4 menuBackground subnode (optional)
	+----------------
	+
	+Specifies the background of main menu.
	+The format is the same as the background subnode.
	+
	+5 menu block (optional)
	+------------
	+
	+Specifies the appearance of blocks used in level selection screen.
	+
	+Syntax:
	+
	+menu(Block){
	+ ...
	+}
	+
	+or
	+
	+menu(ShadowBlock){
	+ ...
	+}
	+
	+The other format is the same as the block subnode.
	+
	+NOTE: if you defined menu(Block) but not defined menu(ShadowBlock),
	+then all blocks used in level selection screen will be menu(Block)
	+regardless of locked or not.
