This is incorrect. Both / and \ will work, but \ is also the escape character (allowing characters like \n for newline), so to use it as a string it needs to be a double slash: \\. It's also worth noting that particles.lua is NOT included in the SMBX 2.0 beta by default (the update will, however, include it) because it was developed after the beta was released. It is likely that you simply do not have the "particles" folder included in your LuaScriptsLib folder.

Spoiler: show

I mean fog this

col=0xFF0000FF

col=0x######FF

fogEmitter:SetParam("col",particles.ColFromHexRGB(0x######));

Thanks for the help!

Please note that "particles.lua" is not the same thing as the "particles" folder. There should be a folder named "particles" in your LuaScriptsLib folder, with files such as "p_snow.ini" in it.

As I said before, \\ will give you the same result as /, but // makes no sense, as / isn't an escape character, which is why that doesn't work.

I suggest you try re-installing particles.

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

AH. If this is your issue you probably have an outdated LunaLua version. Update it.

Use the parameter player.powerup

function onStart()
local savedpowerup=player.powerup
player.powerup=0
