Thanks in advance

I guess you could use two triangles to get this result, but I try to use polys as little as possible and I've never been any good at them :P

Just use surface.DrawPoly( table )

A rhombus is pretty easy to make

What about drawing a rhombus with in a derma paint, would the cords be changed when the derma is moved. Or as its within the derma would it maintain the cords

Well, the x,y is set to the Derma paints x,y meaning 0,0 = top left of your Derma panel

aka y e s

Would anyone care to show me an example?
cheers

-- I'm on some dumb shit.

surface.drawRhombus = function(x, y, w, h, sx, sy)
    local m = Matrix()
    m:Translate(Vector(x, y, 0))
    m:SetField(1, 2, sx/h )
    m:SetField(2, 1, sy/w )

    cam.PushModelMatrix(m)
    surface.DrawRect( 0, 0, w, h )
    cam.PopModelMatrix()
end

How would I re-position the bottom so it sits at a flat 180 degrees, and flip it to be poiting/facing the right rather than the left

[benjiboi]

whenever i move the menu the y axis is messed up, anyone know how to fix this?
im drawing the rhombus with the derma paint func

still need this

[Klaes4Zaugen]

I assume because cam might be a few frames behind, idk.

[benjiboi]

My thought exactly, ish
Tried drawing a rhombus within a derma paint using draw poly and it didnt draw. However when I drew it to screen it worked fine, perhaps its something pertaining to the cords, idk

[Klaes4Zaugen]

Because you have to make the start 0,0 with the surface.DrawPoly in the table.

If you wanna adjust the position its drawn in just use render.SetScissorRect( x, y, ScrW(), ScrH() )

Well you would have to find the coordinates of the top-left corner of the derma, than calculate the draw poly based on that.

Not sure if this'll be a popular solution but have you considered making a rhombus .png in like photoshop or something? It would probably look better too tbh

[benjiboi]

eh, i tried that and i'd rather draw it using draw functions rather than a texture, that being said , has anyone found a method for this?

[editline]7th August 2016[/editline]

still looking for this, If anyone can draw a parallelogram / rhombus within a derma paint I would be forever grateful as its quintessential to my menu

[benjiboi]

this is giving me a headache, i've used four methods but each of them look trash, I still havent figured out how to make a func so im still using broken ass textures
