Drawing a circle that's filled in.

[Lemmiwinks!]

I used this code:
surface.DrawCircle(ScrW()*0.9, ScrH()*0.9, 100, Color(255,255,255,255))
to draw a circle but all I see is the white outline of the circle. How do I fill in the circle completely white?

[whosdr]

I've yet to find a way.
Guess you could use the surface poly function.

[c-unit]

use the drawcircle function like a thousan times and make it 1 unit smaller each time so that its filled in XD

Yeah, because that's obviously a good idea...

[Zephilinox]

[lua]local radius = 100
local maxradius = radius
local saferadius = (maxradius - 1)
for i=1, saferadius do
radius = radius - 1
surface.DrawCircle(ScrW()*0.9, ScrH()*0.9, radius, Color(255,255,255,255))
end[/lua]

Will likely lag, you have been warned.

[whosdr]

[lua]
local radius = 100
local quality = 360
local circle = {}
for i=1,quality do
circle[i] = {}
circle[i].x = math.sin(i/quality*360)*radius
circle[i].y = math.cos(i/quality*360)*radius
end
--In draw hook or whatever
surface.DrawPoly(circle)
[/lua]

Even I think op doesn't deserve this.

Above code is wrong.

[lua]
local sin,cos,rad = math.sin,math.cos,math.rad;
function surface.CreatePoly(x,y,radius,quality)
local circle = {};
for i=1,quality do
circle[i] = {};
circle[i].x = x + cos(rad(i*360)/quality)*radius;
circle[i].y = y + sin(rad(i*360)/quality)*radius;
end
return circle;
end
[/lua]

lua uses radiance not degrees.

[victormeriqui_1]

you could make a crappy one with draw.RoundedBox()

[CowThing]

Best way is to make a texture that is a circle. You could make it white so you can change the color with lua.

[QUOTE=CowThing;26866984]Best way is to make a texture that is a circle. You could make it white so you can change the color with lua.[/QUOTE]

I did some tests... when you have static circle you should a poly otherwise a texture.

Also what the fuck we are doing here, OP is banned and a total asshole.

[Lemmiwinks!]

Bump- I still need help.

[QUOTE=iRzilla;26960796]You've already been answered:

[lua]
local sin,cos,rad = math.sin,math.cos,math.rad;
function surface.CreatePoly(x,y,radius,quality)
local circle = {};
for i=1,quality do
circle[i] = {};
circle[i].x = x + cos(rad(i*360)/quality)*radius;
circle[i].y = y + sin(rad(i*360)/quality)*radius;
end
return circle;
end
[/lua]

And then in a draw hook:

[lua]
surface.DrawPoly(circle)
[/lua]

'circle' obviously already being defined by surface.CreatePoly(x, y, 100, 360)[/QUOTE]

You shittin' me bro? You reposted broken code.

[Lemmiwinks!]

[QUOTE=iRzilla;26962787]Code works fine, you must be Cubar if you can't get it to work.[/QUOTE]

Cubar was pro at Lua and he was a god. Do not disrespect him.

I tried that method the other day, and it works fine.

he probably doesn't know to put it in a draw hook

[QUOTE=TGiFallen;26971716]he probably doesn't know to put it in a draw hook[/QUOTE]

No, I don't. I put it in a HUDPaint hook. Was that wrong? What's a draw hook?

[Lemmiwinks!]

[lua]local sin,cos,rad = math.sin,math.cos,math.rad;
function surface.CreatePoly(x,y,radius,quality)
local circle = {};
for i=1,quality do
circle[i] = {};
circle[i].x = x + cos(rad(i*360)/quality)*radius;
circle[i].y = y + sin(rad(i*360)/quality)*radius;
end
return circle;
end

function DrawingTests()

surface.DrawPoly(circle)

end
hook.Add("HUDPaint", "DrawingTests", DrawingTests)[/lua]

Is the error 'circle is nil' not enough?[/QUOTE]

what's a nil?

[Zephilinox]

NILL is the equivelant of placing a black hole inside another black hole.

[Lemmiwinks!]

[QUOTE=Zephilinox;26983777]NILL is the equivelant of placing a black hole inside another black hole.[/QUOTE]

So basically NILL is an extremely strong gravitational pull?

[Zephilinox]

[QUOTE=Lemmiwinks!;26983815]So basically NILL is an extremely strong gravitational pull?[/QUOTE]

You can't know that until it's actually happened, and we've witnessed it, basically it just means "non-existant".

Its funny how you took my code and totally used it wrong.

The black hole only gets stronger according to the most respected theory.
