If anyone has any requests for complex script ideas that they don't feel like making or are unable to make, post them here. I will try to make it (I'll tell you if it's possible), and they will hopefully be done within a month! Any type (embedded in TPT or standalone, it's your choice, although I can only compile a standalone for Windows)

Sure, you can expect it within 2 weeks, maybe sooner.

...Press E.

(Although if you can give me the function I would use to set what element is selected, I could do it)

No problem!

Here it is:

elements.allocate('AU3FGEN', 'GRVT')
elements.element(elements.AU3FGEN_PT_GRVT, elements.element(elements.DEFAULT_PT_PHOT))
elements.property(elements.AU3FGEN_PT_GRVT, 'Name', 'GRVT2')
elements.property(elements.AU3FGEN_PT_GRVT, 'Description', 'Gravitons. Create Newtonian Gravity. Based off of gravitons from jacob1\'s mod')
elements.property(elements.AU3FGEN_PT_GRVT, 'Color', '0x00EE76')
elements.property(elements.AU3FGEN_PT_GRVT, 'MenuSection', '10')
elements.property(elements.AU3FGEN_PT_GRVT, 'Gravity', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Flammable', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Explosive', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Loss', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'AirLoss', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'AirDrag', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Advection', '1')
elements.property(elements.AU3FGEN_PT_GRVT, 'Weight', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Diffusion', '0')

elements.property(elements.AU3FGEN_PT_GRVT, 'Collision', '0')
elements.property(elements.AU3FGEN_PT_GRVT, 'Properties', 0x10010 )

local g = function(i, x, y, s, n)
--Update Function
if tpt.get_property ( "life" , i ) == 0 then

    tpt.set_property ( "life" , math.random ( 250 , 500 ) , i )

    tpt.set_property ( "vx" , math.random ( -5 , 5 ) , i )
    tpt.set_property ( "vy" , math.random ( -5 , 5 ) , i )

end
simulation.gravMap ( x / 4 , y / 4 , 0.125 )
end
tpt.element_func(g, tpt.element('GRVT2'))

local function gfunc(i, r, g, b)
    return 1, 0x00010001, 255, 0, 238, 118, 255, 0, 238, 118
end
tpt.graphics_func(gfunc, tpt.element("GRVT2"))


It's still far from perfect, but I can keep working on it.

And @Boxmein, I'm currently working on one for jacob1's mod, which can store the 10 most recently-used elements and display them in the bottom-right hand corner. Of course, in his mod, you can use the favorites menu, but it makes it just a bit faster.
