Need help with lua? - LunaLua General Help

[Angelus]

So, I'm supposed to write it this way, right?

Spoiler: show

local HealthPoint = API.load("HealthPoint")
HealthPoint.setNPCHealth(47, 3)
HealthPoint.setNPCDamage(47, 8, 1)

[PixelPest]

Looks right

[Angelus]

Sadly it just gives me an error. I've read somewhere that we shouldn't use HealthPoint because it's old and broken or something alike. Is that right?

[PixelPest]

Quite possibly. What's the error?

[Angelus]

Something among these lines: "attempt to index field 'data' (a nil value)".

[underFlo]

Could you please either take a screenshot or paste the whole error? That makes it easier to troubleshoot the problem.

I'm new to LunaLua and I downloaded the LunaLua with the SMBX application. When I test my script (it is just a simple timer counting upwards per frame), nothing appears in the standard SMBX level editor. Is there something I'm doing wrong? I put the "lunadll.lua" file in my "test" folder in my "worlds" folder, where I also have the level I'm testing it with. Is this wrong?

Yes, that is wrong. You need your level file in the same location as your folder. The level file must not be inside that folder.

For example, if your level is called "myLevel.lvl", then you should have, in your episode folder, "myLevel.lvl", and a folder called "myLevel", inside which should be your lunadll.lua file.

For example, if your level is called "myLevel.lvl", then you should have, in your episode folder, "myLevel.lvl", and a folder called "myLevel", inside which should be your lunadll.lua file.

So the tree (file structure) should be the following, correct? If so, do I have to copy the lunalua.dll to other folders if I want the same to apply to other levels?
SMBX
-|Worlds
---|Test
------|MyLevel
---------|MyLevel.lvl
---------|lunadll.lua

No. MyLevel.lvl needs to be outside the folder. An episode setup would look like this:
SMBX
-|Worlds
---|Test
------|lunaworld.lua //affects all levels in the episode
------|MyLevel.lvl
------|MyLevel
---------|lunadll.lua
------|MyLevel2.lvl
------|MyLevel2
---------|lunadll.lua
------|MyLevel3.lvl
------|MyLevel3
---------|lunadll.lua
etc

I understand it now. Thanks, Enjl!

How can I script: "If a player starts this level with anything other than Small Mario, they become small Mario." (also in relarion to Peach/Toad/Link getting 1 heart piece thing)? Or would it be easier to script that you become small Mario at the start of the level regardless?
I assume that it's possible to script because of lua's flexibility from what I can tell, but if it isn't, then that's a shame.

Code: Select all

function onStart() --runs when the level starts
	player.powerup= 1 --sets player to small (mario, luigi)
	player:mem(0x16,FIELD_WORD,1) --set hearts to 1 (for peach, toad, link)
	player.reservePowerup = 0 --optional, resets item in reserve powerup box to none
end

Use moarrinkas.lua and NPCParse.lua.

but that didnt work for me the engine doesnt know those files are in th folders

Well, you need to type it as ("NPCs//moarrinkas") for it to work. Though, the API's kinda broken as of now so you're better off not using it anyway.

So, when will the rewrite begin just out of curiosity?

It will begin not too long after the NPC array gets expanded and the rewritten version will be bundled with 2.0 full release.

[timocomsmbx2345]

in 2 weeks or so?

[Emral]

in 2 weeks or so?

There are no plans to release another update for 2.0 before the year is over. Please be patient.

maybe 8 weeks?

Can someone give me an idea of how to get an npc to move (like a big leap) to one position to another?
