The Powder Toy

This is my graphics code...

elem.property(neon, "Graphics", function (i, r, g, b)

if sim.partProperty(i, "tmp") ~= nil and sim.partProperty(i, "tmp") == 1 then

return 0,ren.FIRE_BLEND+ren.NO_DECO,255,255,255,125,255,255,125

elseif sim.partProperty(i, "tmp") == nil then

return 0,ren.FIRE_BLEND+ren.NO_DECO,255,r,g,b,r/2,g/2,b/2

end

end)

... Everytime i create neon it will appear as a gray powder, but i expected it to be a gray gas. It only glow and appear as an actual gas when its tmp eq. 1. I couldn't identify the problem (i tried to edit the elseif statement 3 times).

The way the if statement is written the function doesn't return anything when sim.partProperty(i, "tmp") ~= 1 (so it exists but has a value other than 1). I assume that a NEON particle is initialized with tmp 0 which would mean that the element's Graphics function doesn't return anything util you set the particle's tmp to 1.

If my asumption is correct the code should be:

elem.property(neon, "Graphics", function (i, r, g, b)
    if sim.partProperty(i, "tmp") == 1 then
        return 0,ren.FIRE_BLEND+ren.NO_DECO,255,255,255,125,255,255,125
    end
    return 0,ren.FIRE_BLEND+ren.NO_DECO,255,r,g,b,r/2,g/2,b/2
end)

NEON appear as a black floating powder
