    Hello everyone! I have problems with scripting. Can YOU tell me what' s wrong?

    Code:

    local LHYG = elements.allocate(IY, 'LHYG')

    elements.element(elements.IY_PT_LHYG, elements.element(elements.DEFAULT_PT_GLOW))

    elements.property(elements.IY_PT_LHYG, "Properties", elem.TYPE_LIQUID)

    elements.property(elements.IY_PT_LHYG, 'Name', 'LHYG')

    elements.property(elements.IY_PT_LHYG, 'Description', 'Liquid Hydrogenium.')

    elements.property(elements.IY_PT_LHYG, 'Color', '0x99FFFF')

    elements.property(elements.IY_PT_LHYG, 'MenuSection', '7')

    elements.property(elements.IY_PT_LYHG, 'Gravity', 0.4)

    elements.property(elements.IY_PT_LHYG, "Falldown", 2)

    elements.property(elements.IY_PT_LHYG, "State", elem.ST_LIQUID)

    elements.property(elements.IY_PT_LHYG, 'Flammable', '16384')

    elements.property(elements.IY_PT_LHYG, 'Explosive', '1')

    elements.property(elements.IY_PT_LHYG, 'Loss', '0')

    elements.property(elements.IY_PT_LHYG, 'AirLoss', '0')

    elements.property(elements.IY_PT_LHYG, 'AirDrag', '0')

    elements.property(elements.IY_PT_LHYG, 'Advection', '1')

    elements.property(elements.IY_PT_LHYG, 'Weight', '0.4')

    elements.property(elements.IY_PT_LHYG, 'Diffusion', '0')

    elements.property(elements.IY_PT_LHYG, 'Temperature', '17')

    elements.property(elements.IY_PT_LHYG, 'HotAir', '0')

    local function Lflare(i, colr, colg, colb)

    return 1, 0x00000004, 255, 184, 117, 3, 255, 184, 117, 3

    end

    tpt.graphics_func(Lflare, LHYG)

     

    It shows an error message like:

    "scripts\lhyg.lua:8: bad argument #1 to 'property'(number expected)"

    Thanks for your help!

    I think you need to use 
    LHYG
    and not 
    elements.IY_PT_LHYG
    , as 
    elements
    isn't automatically populated with elements you allocate.

     No, that isn't it...

    It doesn't work.

    Another idea?

    So you're telling me 
    LHYG
    is nil too? Something is broken, it looks like

    No, the other scripts are working, so the error is in the script.

     

    New Code:

     

    local LHYG = elements.allocate('IY', 'LHYG')
    elements.element(elements.IY_PT_LHYG, elements.element(elements.DEFAULT_PT_GLOW))
    elements.property(elements.IY_PT_LHYG, "Properties", elem.TYPE_LIQUID)
    elements.property(elements.IY_PT_LHYG, 'Name', 'LHYG')
    elements.property(elements.IY_PT_LHYG, 'Description', 'Liquid Hydrogenium.')
    elements.property(elements.IY_PT_LHYG, 'Color', 0x99FFFF)
    elements.property(elements.IY_PT_LHYG, 'MenuSection', 7)
    elements.property(elements.IY_PT_LHYG, 'Gravity', 0.4)
    elements.property(elements.IY_PT_LHYG, "Falldown", 2)
    elements.property(elements.IY_PT_LHYG, "State", elem.ST_LIQUID)
    elements.property(elements.IY_PT_LHYG, 'Flammable', 16384)
    elements.property(elements.IY_PT_LHYG, 'Explosive', 1)
    elements.property(elements.IY_PT_LHYG, 'Temperature', 17)
    local function Lflare(i, colr, colg, colb)
    return 1, 0x00000004, 255, 184, 117, 3, 255, 184, 117, 3
    end
    tpt.graphics_func(Lflare, LHYG)

     

    Now, the liquid is in TPT and also flammable and explosive. But there' s just one thing: the colour! It' s brown, but my colour is very light blue!

     

    Idea?

    You are defining a graphics function but telling that to make your element brown, not 0x99FFFF like the property you set. Here is a fixed version, I looked here to figure it out: https://powdertoy.co.uk/Wiki/W/Lua.html#tpt.graphics_func

    Note that the graphics function here does nothing special that isn't done by default, maybe you want to add more properties? Or just remove it.

    local LHYG = elements.allocate('IY', 'LHYG')
    elements.element(LHYG, elements.element(elements.DEFAULT_PT_GLOW))
    elements.property(LHYG, "Properties", elem.TYPE_LIQUID)
    elements.property(LHYG, 'Name', 'LHYG')
    elements.property(LHYG, 'Description', 'Liquid Hydrogenium.')
    elements.property(LHYG, 'Color', 0x99FFFF)
    elements.property(LHYG, 'MenuSection', 7)
    elements.property(LHYG, 'Gravity', 0.4)
    elements.property(LHYG, "Falldown", 2)
    elements.property(LHYG, "State", elem.ST_LIQUID)
    elements.property(LHYG, 'Flammable', 16384)
    elements.property(LHYG, 'Explosive', 1)
    elements.property(LHYG, 'Temperature', 17)
    local function Lflare(i, colr, colg, colb)
    return 1, 0x00000004, 255, 153, 255, 255, 255, 153, 255, 255
    end
    tpt.graphics_func(Lflare, LHYG)

    elements is filled with things you allocate, it's tpt.el that isn't.
