Description:: Draws one to multiple triangles on the map.

ⓘ
When fill param is absent or is an empty string "", the triangle is drawn with lines of the color set in color param. In order to draw color-filled triangle of the same color as color param, set fill param to opaque white procedural texture"#(rgb,1,1,1)color(1,1,1,1)".
Groups:: GUI Control - Map

Syntax:: map drawTriangle [vertices, color, fill]
Parameters:: map: Control - map control
: vertices: Array of Positions - triangle(s) vertices in multiple of 3, see Example 1 - if Position3D is provided for a vertex, its z value is ignored
: color: Array in format Color (RGBA)
: fill: String - (Optional, default "") fill texture file or Procedural Textures. See note in description for more info.
Return Value:: Nothing

Example 1:: Copy
findDisplay 12 displayCtrl 51 ctrlAddEventHandler ["Draw", { _this select 0 drawTriangle [ [ // triangle 1 start player getRelPos [100, 0], player getRelPos [100, -135], player getRelPos [100, 135] // triangle 1 end ], [1,0,0,0.5], "#(rgb,1,1,1)color(1,1,1,1)" ]; }];
