__NOTOC__
This function draws a number of 2D lines in order to achieve a circle shape on the screen - rendered for '''one''' frame.  This should be used in conjunction with [[onClientRender]] in order to display continuously.
 
==Syntax==
<syntaxhighlight lang="lua">bool dxDrawCircle ( int posX, int posY [, int radius = 50, int, width = 5, int angleAmount = 1, int startAngle = 0, int stopAngle = 360, int color = white, bool postGUI = false ] )</syntaxhighlight>
 
===Required Arguments===
[[Image:DxDrawCircle_example.png|thumb|An example of how dxDrawCircle function works in practice.]]
* '''posX''': An integer representing the '''absolute''' X position of the circle center, represented by pixels on the screen.
* '''posY''': An integer representing the '''absolute''' Y position of the circle center, represented by pixels on the screen.
 
===Optional Arguments===
{{OptionalArg}}
* '''radius''': An integer representing the radius scale of the circle that is being drawn.
* '''width''': An integer representing the width of the line that is being drawn.
* '''angleAmount''': An integer representing the tightness of the circle. Lower amount makes it smoother, higher amount makes it more of a clock looking circle.
* '''startAngle''': An integer representing the angle of the first point of the circle.
* '''stopAngle''': An integer representing the angle of the last point of the circle.
* '''color''': An integer of the hex color, produced using [[tocolor]] or 0xAARRGGBB (AA = alpha, RR = red, GG = green, BB = blue).
* '''postGUI''': A bool representing whether the line should be drawn on top of or behind any ingame GUI (rendered by CEGUI).
