Need help with lua? - LunaLua General Help

Did you set the .wld file's name in the editor?

Yeah, but I mean NO world names are showing up. Even the Invasion 2!

Oh. You mean on the main screen. I don't think you could really fix that easily. Have you actually checked to see if the .wld files have names inside the file?

Yeah, they do. Maybe I'll just look through and see what happened later.

[HenryRichard]

Sounds like you need to reinstall smbx.

The legacy editor should use lunalua scripts. I've never gotten the new editor to test correctly. Is the folder you posted the folder for the level? If so, why are there .lvl files in there?

It's the folder the level is in. I've been grouping levels by world.

Then your lunalua file won't work. It has to be inside the level folder, with the level itself outside that folder.

How do I make a level folder? My computer won't let me name the folder like my level is named.

You don't add ".lvl" to the end, but if it still won't let you you need to change your level name.

Okay, I did it, but the code still does nothing. I put in a Text.print() code, to show my variable and still no changes occurred. Nothing showed up.

Can you show another screenshot of your level folder, and post your code?

Oh! I wonder if there is a way where I can make all blocks slippery instead of just selecting a block and enable slippery.

[Quantumenace]

To do something with multiple objects you need to use a loop. If you want every block in the entire level,

Block.get()

returns a table with references to all the blocks. To do something with them you can use the "pairs" keyword which cycles through all entries in the table using the variables provided:

for k,v in pairs(Block.get()) do ...... end

In this case, v represents the value at index k in the table. The value v is a reference to the block, and you can modify its "slippery" flag with v.slippery = true.

Code: Select all

for k,v in pairs(Block.get()) do 
	v.slippery = true
end

Don't forget the "end" or you'll get a "function failed to close" error.

You need to put this in an onStart() function or something, just putting it outside functions will try to run it before the blocks are even loaded.

Anyways, the wiki has a lot of information on this stuff. This page is a good place to start on the basics.

So, I'm trying to use the Raocoins.lua for my episode, but when I put this in the lunaworld file:

Code: Select all

local raocoin = loadAPI("raocoin");

...the thing crashes. I read the error and it's something about it using registerEvent with strings. Is there anything I can do to fix this?

You're using the wrong library. "raocoin" is an old outdated library, while "raocoin2" is a modern one.

Also use API.load since loadAPI is deprecated

This is what the code looks like when I made it, it crashed.

onStart() function

for k,v in pairs(Block.get()) do 
   v.slippery = true
end

I don't know what I did wrong.

1. Function onStart() not onStart() function
2. On start does things once, when level starts. Use function onLoop() or function onTick() there

[underFlo]

^ Also, you need one more end

(even though I'm pretty sure that onStart() would be the right function for this, but I may be wrong)

[PixelPest]

You really need take some time to learn the basics, if you don't even know where to put "function"

[Hani]

The code didn't crash when I added the other end but it's not making the blocks slippery. ???

[PixelPest]

Then use function onTick(). That should work

function onTick() also doesn't work.
