[SM5] Get Difficulty Within ScreenGameplay?

Hi all,

Just wondering how I can find out the difficulty of the song currently being played? I'd like to adjust some decorations if the difficulty is Challenge and I can't seem to work out how to check if the current difficulty is challenge.

Hope someone can help, thanks in advance!

Please check the lua docs. https://dguzek.github.io/Lua-For-SM5/API/Lua.xml#GameState

GAMESTATE:GetCurrentSteps(pn):GetDifficulty() will return the difficulty. https://dguzek.github.io/Lua-For-SM5/API/Lua.xml#ENUM_Difficulty

Substituting pn for the player you want.

EDIT: Oops, sniped by ZTS. Oh well.

I could just hand you the code to make this happen, but it's probably better to guide you to the solution.

1. Do you know how to use StepMania's Lua.xml API?

2. What is "the current difficulty" an attribute of? By which I mean, is difficulty an attribute of a player? Is difficulty an attribute of a song?

If you respond to these questions, I can try to help you from there.

Thanks for the responses guys, I already have code for it, but it wasn't working. I should have included it within my original post.


I'm not sure how to use the enums to get what I'm after. Could I say:


Or should I be saying:


I knew what I was going for and I already worked out the appropriate calls, I should have explained myself a bit better in the first post as I was just after how I can use the enum to work it out. I'm not as fluent on how to use enums as I am with other parts of lua coding.

Actually I might need to use GetHardestStepsDifficulty() in this case as I would want to apply the code for the whole screen if the hardest difficulty is challenge.

Can someone explain how I can use the enum values? You don't have to give me the code, but it'd be great if you could explain how to use the enums within the code as that's where I'm getting lost.

Thanks again.

local r = Enum.Reverse("Difficulty");
local s = r[GAMESTATE:GetCurrentSteps():GetDifficulty()];

s value will return the enum equivalent

I'm still confused. Here's my code, I put your suggestion in to replace how I was trying to attain the difficulty:


I'm trying to get the storm background to play in this instance when a challenge song is being played. I would like to be able to detect if the song has mines in it too but I think that's way too far outside of my knowledge base as I've looked at how other themes get the "Shock Arrow" icons on the song wheel to show up and I couldn't really wrap my head around that.

Am I using the value incorrectly? When I run the code, it's just showing the video all the time, no matter whether it's a challenge difficulty or not.

Sorry that I'm not understanding properly.

1. You didn't put PLAYER_1 or PLAYER_2 in GetCurrentSteps(), which is required for it to work. Also, GetDifficulty doesn't accept any arguments.

2. If you want the difficulty as a number for some reason, the above works fine but here's the one line method.
Difficulty:Reverse()[d] (Where d is a difficulty enum)

3. I already linked that GAMESTATE:GetCurrentSteps(pn):GetDifficulty() will always return a value from the difficulty enum, which is one of these strings: "Difficulty_Beginner", "Difficulty_Easy", "Difficulty_Medium", "Difficulty_Hard", "Difficulty_Challenge", "Difficulty_Edit". You just need to check if it's one of these strings.


If you think that's too long to type you can do ToEnumShortString(d) where d is a difficulty enum. For example, "Difficulty_Beginner" will become "Beginner".

4. You are trying to compare a string "4" to a number. You want s == 4, not s == "4". Putting quotes around something means it's a string.

Sorted it! Thanks for your help guys, now I understand the enums better and how to use them properly, I'll see if I can work out how to find out if a song has mines.

My code ended up being:
