Need help with lua? - LunaLua General Help

[Mario_and_Luigi_55]

You can only have one function of each name in your lunadll.lua file.
Also, maximum player fall speed is 12, so even if it worked, it wouldn't be noticable if the player was already falling.

But will function for example onKeyDown work if I would rename IT?

Just throw your two onKeyDown and onLoop functions into one each?

[Mario_and_Luigi_55]

Can I change things that volcano lotus shoots (for example can it shoot springs instead of fireballs)

[Emral]

Yeah, just change the ID of the NPC it's shooting.

no static mem in NPC.

Thi error is boring. I get in millions of times when i try doing anything...

Code: Select all

function onLoop()
    for k,v in pairs(NPC.get(275,-1)) do
        NPC:mem(0xF8,FIELD_DFLOAT,26)
    end
end

NPC refers to your NPC object. If you wrap a table into a for loop which iterates over each object (v) with the key (k), you need to use v.

Code: Select all

function onTick()
   for k,v in ipairs(NPC.get(275, -1)) do
      v.id = 26
   end
end

OK. Thanks

So I've used this specific code from the wiki in a level:

Code: Select all

local SMWCam = loadAPI("SMWcamera")
local t = 0   -- Frame timer
 
function onTickEnd()
	-- Pans the camera to the right, wobbles the camera up and down (like on an airship)
	SMWCam.BeginAutoScroll(2, math.cos(t*math.pi/180))
 
	-- Increment frame timer
	t = t + 1
end

It's supposed to fiddle with the normal camera, but all it does is shove the player to the right. Am I missing something here?

By the way, apologies in advance for any further stupid questions I might make. I'm quite new to this whole thing.

This exact same code seems to work for me. Be sure that the section allows enough room for camera movement both vertically and horizontally.

Not really my code or anything but I'm having trouble getting ParalX.lua to work (even on the example level there) :v

Apparently I'm getting some error related to Graphics.draw - I really can't Lua (so it's likely it's just me being stupid lol) but I think it has to do with the version I'm using, the one that comes with SMBX 2.0.

Tried updating (dunno if that would actually change anything though ¯\_(ツ)_/¯) but it didn't work for some reason, it kills the sound and I'm pretty sure Lua completely stops working as well. Did pretty much what was on the first post.

So yeah, I'm super confused and I have no idea if anything here actually helps lol

Your lua is likely out of date.

How can I do fog in the level?

[Emral]

How can I do fog in the level?

http://wohlsoft.ru/pgewiki/Particles.lua
If you download the package there are some example ini files which you can use. You just need some kind of white mist sprite to represent fog (I don't think they're included in the download, but they'll be available with the next 2.0 beta. For the time being, you can try making one yourself).

[Hoeloe]

(I don't think they're included in the download, but they'll be available with the next 2.0 beta. For the time being, you can try making one yourself).

They should be included in the download. One of the example particle systems is a fog effect.

Wait, the example doesn't work

Code: Select all

local particles = loadAPI("particles");
 
local effect = particles.Emitter(0, 0, Misc.resolveFile("particles/p_rain.ini"));
effect:AttachToCamera(Camera.get()[1]);
 
function onCameraUpdate()
    effect:Draw();
end

Why? The / is flipped it should be \, but lua says:

for particles/anythinghere.ini - cannot open
and for particles\anything.ini - invalid escape near 'particles'

I have all the required .lua files from particles.lua (they are in SMBX 2.0 by deafult)
