The CodeMessageCommand part should be in a BGAnimation-side lua script, e.g. 

local t = Def.ActorFrame{

	Def.Actor{

		Name="CodeController";

		CodeMessageCommand=%function(self, param)

			Trace("CodeMessageCommand received.")

			local codeName = param.Name		-- code name, matches the one in metrics

			local pn = param.PlayerNumber	-- which player entered the code

		end

	};

};

Can I hide or show stepinfos as I wish by using this code and other little add-ons?
(Press a button,then they hide.Press again,they show again~)

And more,who can help me with a small function?
I want to let my theme load a special named image in every song folder(e.g. There is a "title.png" in every single song folder.And it will be load by ScreenSelectMusic overlay every time the musicwheel changed.)
I added this in 99 xxx.lua,but it often shows"Dialog: "Lua runtime error: /Themes/Sigma1 -The Blue Dasher-/Scripts/99 xxx.lua:1: unexpected symbol near '?" [LUA_ERROR]" 

function HasTitle()

local song = GAMESTATE:GetCurrentSong();

local course = GAMESTATE:GetCurrenCourse();

	if song then

		local path=song:GetSongDir();

			if FILEMAN:DoesFileExist(path.."../title.png") then

				return true

			else

				return false

			end

	elseif course then

		local path=course:GetCourseDir();

			if FILEMAN:DoesFileExist(path.."../title.png") then

				return true

			else

				return false

			end;

	end;

end;



function GetTitlePath()

local song = GAMESTATE:GetCurrentSong();

local course = GAMESTATE:GetCurrenCourse();

local st;

	if song then

		local path=song:GetSongDir();

			if FILEMAN:DoesFileExist(path.."../title.png") then

                                st = path.."../title.png"

			else

                                st = ~nil

			end

	elseif course then

		local path=course:GetCourseDir();

			if FILEMAN:DoesFileExist(path.."../title.png") then

                                st = path.."../title.png"

			else

                                st = ~nil

			end;

	end;

        return st;

end;

Gotta be more specific than that on what's confusing you on theming

like how do you make BGAnimations,Fonts,and Graphics? and how to put in the sounds and scripts? im not sure if i need to put anything in the languages folder. lol i know i should have been known all of this stuff but im xtremely new to theming from scratch.

Yes, you can. Freem actually had a typo in his example, that "%" should not be there, if this is in a lua file.

I added this in 99 xxx.lua,but it often shows"Dialog: "Lua runtime error: /Themes/Sigma1 -The Blue Dasher-/Scripts/99 xxx.lua:1: unexpected symbol near '?" [LUA_ERROR]"


"~nil" is not valid lua. You want to just set st to nil.

I had a try:Added these in the [ScreenSelectMusic] metrics:
CodeNames="ShowInfo"
CodeShowInfo="Select"

And put this in ScreenSelectMusic overlay.lua: 

local t = Def.ActorFrame{

	Def.Actor{

		Name="CodeController";

		CodeMessageCommand=function(self, param)

			Trace("CodeMessageCommand received.")

			local codeName = param.ShowInfo

			local pn = param.PlayerNumber_P1

		end

	};



	LoadActor(THEME:GetPathB("","_Materials/cover"))..{

		InitCommand=cmd();

		OnCommand=cmd(horizalign,left;y,SCREEN_BOTTOM-70;zoomto,854,200;diffusealpha,0;accelerate,0.2;diffusealpha,0.9;cropleft,0.5); 

		OffCommand=cmd(sleep,0.1;accelerate,0.3;diffusealpha,0;);

		CodeMessageCommand=function(self)

			local a;

			a=true

				if a then

					self:diffusealpha(0);

					a=false

				else

					self:diffusealpha(1);

					a=true

				end;

			end;



	};

  ...

};


When I press "Select",It disappeared correctly.but when I press again.....nothing happened.Is there some thing wrong?Or the codes can only be typed one time?

EDIT:alright....I found the problem-every time the CodeMessageCommand is run."a" will be "true"......I fixed it and it works.Now I just need someone fix my 99 xxx.lua....: 

function HasTitle(song)

	local path=song:GetSongDir();

	if FILEMAN:DoesFileExist(path.."../title.png") then

		return true

	else

		return false

	end;

end;

function GetTitlePath(song)

	local st;

	if HasTitle(song) then

		local path=song:GetSongDir();

			st=path.."../title.png"	

	else

		st=a

	end;

        return st;



end;

function GetTitlePath(song)

	local st;

	if HasTitle(song) then

		local path=song:GetSongDir();

			st=path.."../title.png"	

	else

		st=a

	end;

        return st;

end;

Why are you setting st to a? That looks like a mistake.

Should I just set st=nil? QUQ,I tried but failed.I even delete that whole function (GetTitlePath(song)).But it still has bugs....

I spent a couple minutes adding this to my theme so see what problems there might be, and I didn't run into any.

Inside one of my Scripts/ lua files: 
function GetTitlePath(song)

	local path=song:GetSongDir()

	if FILEMAN:DoesFileExist(path.."../title.png") then

		return path.."../title.png"

	end

	return nil

end


Inside ScreenSelectMusic overlay.lua, in the ActorFrame that it returns: 
	Def.Sprite{

		InitCommand= cmd(xy, SCREEN_CENTER_X, SCREEN_CENTER_Y),

		Name="title_img",

		CurrentSongChangedMessageCommand=

			function(self)

				Trace("title_img changing.")

				local song= GAMESTATE:GetCurrentSong()

				if song then

					local title_path= GetTitlePath(song)

					Trace("Path: " .. tostring(title_path))

					if title_path then

						self:Load(title_path)

						self:diffusealpha(1)

					else

						Trace("No path.")

						self:diffusealpha(0)

					end

				else

					Trace("No song.")

					self:diffusealpha(0)

				end

			end

	},


And it works. I decided HasTitle was superfluous, so I didn't use it.

I created another new lua file,and write these codes.This time I didn't get bugs. Thanks Kyzentun~
Hope our discussion can help other people.
