__NOTOC__
This function draws a polygon with a custom number of its sides.

==Syntax==
<syntaxhighlight lang="lua">dxDrawPolygon( int x, int y, float radius, int sides, int color, [ float rotation, float width=1 ] )</syntaxhighlight>

===Required Arguments===
* '''x:''' An integer representing the absolute X position of the middle of the polygon's circumcircle.
* '''y:''' An integer representing the absolute Y position of the middle of the polygon's circumcircle.
* '''radius:''' A float representing the radius of the polygon's circumcircle.
* '''sides:''' An integer representing the number of the polygon's sides.
* '''color:''' An integer of the hex color, produced using [[tocolor]] or 0xAARRGGBB (AA = alpha, RR = red, GG = green, BB = blue).

==Optional Arguments==
{{OptionalArg}}
* '''rotation:''' A float representing the polygon's rotation in degrees.
* '''width:''' A float representing how thick the polygon's sides will be.

==Code==
<section name="Client" class="client" show="true">
<syntaxhighlight lang="lua">
function dxDrawPolygon(x, y, radius, sides, color, rotation, width)
local last = {}
for i=0, sides do
local radian = math.rad( (rotation or 0) + i*(360/sides) )
local lineX, lineY = x + radius * math.cos(radian), y + radius * math.sin(radian)
if (last[1] and last[2]) then
dxDrawLine(last[1], last[2], lineX, lineY, color, width or 1)
end

==Example==
<section name="Client" class="client" show="true">
This example draws a white hexagon in the middle of the screen.
<syntaxhighlight lang="lua">
