I found a code by MECHDRAGON777 that should make Peach spin-jump, but I don't understand how to get it to load, I've been trying for the past couple of hours, but I just don't seem to get it. Can someone tell me what I need to put in the lunaworld.lua file to get this to load?

end
Also, with that code, you need to copy the sound effect from ../SMBX/sound into your custom graphics folder.

Why not just use playSFX()? Also, you don't need to test for true. (y==true is the same as y)

I've heard claims that this topic doesn't do a good job at telling people how to get lunalua installed and running properly, so here's a step by step in case you're having trouble:

1)

Enjl wrote:Go to http://wohlsoft.ru/LunaLua/ and follow the download instructions. Selecting "Vanilla + Launcher" should work in most cases. If not, try "Hexed".

Make sure you download the latest build. After downloading you should be greeted with a zip like this:

2a)

Enjl wrote:Extract the contents of the zip into your smbx directory

OR 2b)

Enjl wrote:create a new one if you ticked "Include standalone base game"

Tadaa! After completing these steps your SMBX will be lua-compatible and you can take a look at the documentation or join the codehaus discord to get started in writing your own code!

Hope that cleared things up for you,

I primarily don't need it yet for own level design, I need it to have my game engine lua-compatible so it can deal with lua-stuff like it e.g. appears in Tower of Biased X (when playing ToB X without Lua, you get runtime errors everywhere). I also have an application file called "LunaLoader" in my folder which doesn't appear in screenie 1), and I can't open it.

I'm also trying to install SMBX 2.0, that will maybe work out.

Emral · Postby **Emral** » Thu Sep 22, 2016 9:34 am

LunaLoader is further offscreen. You should be able to run the SMBX.exe which comes with the zip, though. That one's lua-compatible too.

As for 2.0, it might be better to wait for Beta 3 at this stage. We're aiming for a release VERY soon, so if you can hold out for a few days you can get the most recent lua + 2.0 all in one package.

I have gotten this error three times now testing my episode (in different levels).

It always seems to happen after I've had a big amount of deaths and occurs when the level is restarting. How should I start finding the cause of this?

EDIT: And this one which I think started occuring once I added custom player characters, but not sure.

The above problem was solved by removing the custom player character graphics. However, now I'm facing a new issue.

This error appears when starting any level that uses Healthpoint.lua.

Here is the actual healthpoint.lua (I copied the one that came with SMBX 2.0 Beta 3 but the same error appeared with the older version of this file). It's probably better to check this in your own SMBX if you have BETA 3 since you can see the line numbers:

And here is my lunadll.lua for the level:

I did not have this problem on the previous version of SMBX2.

Your LunaLUA seems to be outdated. Try the nightly build, see if that helps.

Don't use healthPoint it's known for being deprecated and that it breaks stuff. It was built with graphX (an outdated API) and an old version of colliders in mind. Until someone makes a replacement (we're waiting for onNPCHarm for this, essentially) you're probably better off just coding the hp values into your own lua file.Should be just a pnpc.data counter.
Don't use onLoad it's bad. (onStart instead)
Don't use loadAPI it's bad. (API.load instead)
Use player.character instead of 0xF0.
Why kill the player when they hit drop item?
The openGL errors are because as a level reloads over and over, the graphics get loaded over and over too until a limit is reached (something like that).

Also why copy individual files FROM beta 3 if you can just work with beta 3 to begin with? Copying individual stuff out of there without knowing what it relies on is asking for trouble.

Ahh, more work to do.

Thanks.

The drop item key is a suicide button (for when a puzzle has gone wrong).

there's a cheat code in beta 3 for that called "suicide"

Well the whole point of it is to be able to access it in a nanosecond.

But honestly I'm at a loss with the pnpc.data counter, is there any kind of tutorial for it?

initialisation:
for k,v in pairs(id) do
w = pnpc.wrap(v)
if w.data.hpCounter == nil then w.data.hpCounter = 20 end
end
w.data.hpCounter is a variable saved for each npc you save it for and can be accessed across ticks. The idea is to cancel the killObj if it's greater than 0 in onNPCKill.

My worry with the suicide button is that people will press it by accident BECAUSE it's immediately accessible. Can lead to very frustrating deaths.

1. Is it possible to get and/or alter the text of the currently displayed SMBX Message box?
2. Is it possible to use SMBX Message Boxes as a point of reference for drawing sprites? (i.e. Drawing a sprite at a certain spot in the message to display a character or something like that)

Sorry if this has been asked or answered already. How would you go about using Lua to change the default sound effects and BGM episode-wide? I'm looking to attempt to export the Super Talking Time Bros games to 2.0, but since they used their own sound effects and world map BGMs I'd need to figure out how to code that.

2. Is it possible to use SMBX Message Boxes as a point of reference for drawing sprites? (i.e. Drawing a sprite at a certain spot in the message to display a character or something like that)

1) there is an onMessageBox event that has the message as a second argument
2) Not really. You can however use textblox.printExt to print with your own font which has that special character looking like something else. Using onMessageBox you're able to cancel the event (first argument) and then load the message into a textblox printExt call. That should work for what you're trying to do. Keep in mind textblox is being updated heavily right now so you should keep the version you're working with around in case backwards compatibility gets lost somehow.

Check smbx/ini_examples. You can copy sounds.ini and musc.ini over to your episode folder and replace filepaths

Thanks for the reply. I found the file and it looks like it should be straightforward, but I can't get it to work. For now I'm just trying to replace the smw-exit.ogg sound, so I put my version in a folder called 'sounds' in my episode folder (currently just called 'test'), but nothing I add to the filename in the ini file is working. Not sounds/smw-exit.ogg, test/sounds/smw-exit.ogg, worlds/test/sounds/smw-exit.ogg, or data/worlds/test/sounds/smw-exit.ogg. How should I be pointing it to that location?

It might just be that you should use \ instead of /, I think I had the same mistake. It should be sounds\smw-exit.ogg.

Try renaming the file to be something other than the original filename. It might search in the main directory. (I have a setup with resources/sfx_null.wav which works)
If that doesn't work, there's a bug I noticed with LunaTester in PGE regarding episode-wide sounds.ini
For some reason sounds.ini sometimes does not work unless a level-wise sounds.ini was loaded before (I don't know if this was fixed yet). Try sounds/smw-exit.ogg (or your new filename format) once more, but test it from the main game if possible. Though not being able to properly hear the sound when testing is a nuisance, you can confirm that it works this way.

No, / works.

Ah, right, now I remember the mistake. I did not restart SMBX before testing again.

In other news, I'm still going to take a risk and leave the healthpoint.lua in. The error was caused by having a generator in the level. I can easily live without the generator but fixing and figuring out a health point code for countless levels would be too much. Hopefully it won't break any more in the future (wink wink lua developers).

Healthpoint is an old API not part of lunalua core and is only included for backwards compatibility at this point. The oversight of generators is one of the things where I mentioned that it breaks. I don't see any updates to the API happening without a complete rewrite and only once onNPCHarm is a thing, so for now your only chance to fix generators is to modify the api yourself, really.
