Lua bindings in 3.95/OpenITG

[dj jack]

Ok guys, here's the problem: I don't get how I'm supposed to use the lua bindings.

For example I needed to work with the active percentage during the song, I found on the StepMania theming wiki that GetPercentDancePoints was added in PlayerStageStats, then I luckily found the STATSMAN:GetCurStageStats():GetPlayerStageStats(pn ):GetCaloriesBurned() line in other.lua and modified it for my needs, but I still don't understand how to build that "address". Can somebody please explain it to me?

Please guys, I really need this in a short time!

You can use singletons anywhere you would use a value.

I know that, what I need to know is how the STATSMAN:GetCurStageStats():GetPlayerStageStats(pn ):GetCaloriesBurned() line was determined. What I mean is: GetCaloriesBurned() is listed on this page http://www.stepmania.com/wiki/Lua_sc...Actor_commands under the PlayerStageStats class. How can I understand in wich singleton is every class comprised?

Let's say I need to get the highest machine score for the currently playing song. I see a GetPercentDP( ) function in the HighScore class, but how can I actually refer to it in the lua scripts?

Come on, I can't believe none of the awesome themers knows the answer.. Please =(

Getting PlayerStageStats:
@STATSMAN:GetCurStageStats():GetPlayerStageStats(P LAYER_1):GetCaloriesBurned();
should return something. like:
<BitmapText File="Blah" NoteCrossed250Command="@function(self) self:settext(STATSMAN:GetCurStageStats():GetPlayer StageStats(PLAYER_1):GetCaloriesBurned()); end;"
/>

that is, if I recall correctly. I could be wrong and might have to try it out but I dont have anything to do with at this time

That still doesn't help me in understanding how to call the GetPercentDP( ) function in the HighScore class or any other function. =/ What I don't get is how to reach, for example, the HighScore class starting from a singleton.

Ok I'll try to be more clear: I need to access the highest score for the current song while inside of ScreenGameplay. I've been reading the source code for hours and still haven't got a clue on how to build the function call. Can somebody please help me?

the high score list requires a profile, so this is a multi-step process.

First, you need to get the correct profile. I use this function to do that:

function Profile(pn)
	if PROFILEMAN:IsPersistentProfile(pn) then
		-- player profile
		return PROFILEMAN:GetProfile(pn);
	else
		-- machine profile
		return PROFILEMAN:GetMachineProfile();
	end;
end;

This is done to make sure we have a profile to fall back on, in case the player isn't using one.

From there...

<BitmapText
	File="Blah"
	OnCommand="@playcommand,Set"
	SetCommand="@function(self)
		local SongOrCourse, StepsOrTrail;

		local scorelist;
		local text = "";
		local profile;

		if GAMESTATE:IsCourseMode() then
			SongOrCourse = GAMESTATE:GetCurrentCourse();
			StepsOrTrail = GAMESTATE:GetCurrentTrail(pn);
		else
			SongOrCourse = GAMESTATE:GetCurrentSong();
			StepsOrTrail = GAMESTATE:GetCurrentSteps(pn);
		end;
		if SongOrCourse then
			if StepsOrTrail then
				profile = Profile(pn);
				scorelist = profile:GetHighScoreList(SongOrCourse,StepsOrTrail);
				assert(scorelist);
				local scores = scorelist:GetHighScores();
				local topscore = scores[1];
				if not topscore then
					text = string.format("%.2f%%", 0);
				else
					text = string.format("%.2f%%", topscore:GetPercentDP()*100.0);
				end;
			else
				text = "";
			end;
		else
			text = "";
		end;
		self:settext(text);
	end;"
/>

Even though it's not for OpenITG, I'm going to link the SM4CVS Lua reference, as a lot of the commands/structures exist in OpenITG.

Hope this helps.

I love you.

Also I've been using this but it looks outdated and incomplete. Thank you very much for your advice =) It is EXACTLY what I needed!

EDIT: Sadly it doesn't really work. I think there is something wrong as the GetHighScoreList function is nowhere to be seen in OpenITG's source code =(
