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]]; }];
