cool :D i made something like that before, but it only shuffles the colours. i've also shorten the code a bit

tpt.el.bran.menu=1
tpt.el.bran.enabled=1
tpt.el.bran.menusection=5

tpt.el.bran.name="NEON"
tpt.el.bran.description="Neon gas - glows in contact with electricity"
tpt.el.bran.color=0x00242424
tpt.el.bran.gravity=0
tpt.el.bran.diffusion=1
tpt.el.bran.advection=2
tpt.el.bran.properties=0x4828
tpt.el.bran.flammable=0
tpt.el.bran.heat=295
tpt.el.bran.weight=0
tpt.el.bran.airloss=1

local colour={0xFFAA0000,0xFFFF6600,0xFFFFFF00,0xFF00FF00,0xFF00FFFF,0xFF0000FF,0xFF9900CC}
local none=0x00242424

function neon(i,x,y,s,n)
    if tpt.get_property("tmp",i)== 0 then
        tpt.set_property("tmp",1,i)
    end
    if tpt.get_property("tmp2",i)== 1 then
        tpt.set_property("life",150,i)
        tpt.set_property("tmp2",0,i)
    end
    if tpt.parts[i].life<=0 then
        tpt.set_property("dcolour",none,i)
    end
end

function neonsprk(i,x,y,s,n)
local ntmp=tpt.get_property("tmp",tpt.el.bran.id)
type=tpt.get_property("ctype",x+math.random(-1,1),y+math.random(-1,1))
    if tpt.get_property("ctype",i)==tpt.el.bran.id then
        if tpt.get_property("tmp",i)==ntmp then
            tpt.set_property("dcolour",colour[ntmp],i)
            tpt.set_property("tmp2",1,i)
        end
        if tpt.get_property("tmp",i)==8 then
            tpt.set_property("dcolour",colour[math.random(1,7)],i)
            tpt.set_property("tmp2",1,i)
        end
    end
end

function neongraphics(i, colr, colg, colb)
    return 1,0x00022110,30,30,30,30,30,30,30,30
end

tpt.graphics_func(neongraphics,tpt.el.bran.id)
tpt.element_func(neon,tpt.el.bran.id)
tpt.element_func(neonsprk,tpt.el.sprk.id)

okay, thanks for the advice

copy the code from the first post --> @mrsalit0s (View Post) into your text editor, save it as autorun.lua and put the file into your powder toy directory. you could also use cracker64's script manager https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=14596

but then you shouldn't save the file as autorun.lua. name it neon.lua then.

BRAN is an unused element slot. if you changed it to other life elements it won't work. don't know how other elements would behave if you use this script with them. could be that its not working with some.
