Description

Description:
Draws given polygon on the given map control with given color. The polygon must consist of at least 3 points. Unlike with other draw* commands and due to complexity, this command does not support filling of the polygon with color. Use drawTriangle command to construct and fill polygon shape as a workaround.
Groups:
GUI Control - Map

Syntax

Syntax:
map drawPolygon [polygon, color]
Parameters:
map: Control
polygon: Array of Position3D
color: Color (RGBA)
Return Value:
Nothing

Examples

Example 1:
test_polygon = []; for "_i" from 1 to 12 do { test_polygon pushBack (player getPos [10 + random 100, 360 / _i]); }; findDisplay 12 displayCtrl 51 ctrlAddEventHandler ["Draw", { params ["_control"]; _control drawPolygon [test_polygon, [0,0,1,1]]; }];
Example 2:
Draw a polygon by adjusting the _radius and _numVertices
vertices = []; private _numVertices = 2; private _numVertices = _numVertices max 3; private _radius = 100; for "_i" from 1 to _numVertices do { vertices pushBack (player getRelPos [_radius, 360 / _numVertices * _i]); }; findDisplay 12 displayCtrl 51 ctrlAddEventHandler ["Draw", { params ["_control"]; _control drawPolygon [vertices, [0,0,1,1]]; }];
