Description:: Draws a static arrow (outline or color filled) on map. See Example 4 for arrow removal.
ⓘ
Note that the order in which arrows are added to map is reversed, the last added arrow will appear under the first added arrow
Execution:: call
Groups:: Map and Markers

Syntax:

[from, to, color, pars, fill, map] call BIS_fnc_drawArrow

Parameters:

from: Array - Arrow start position in format [x,y] or [x,y,z]

to: Array - Arrow end position in format [x,y] or [x,y,z]

color (Optional): Array - Arrow line or fill color in format [r,g,b,a]. Default: [1,1,1,1]

pars (Optional): Array - Arrow geometry details in format [arrowThickness, arrowHeadLengthCoef, arrowHeadWidthCoef], where:

arrowThickness (Optional): Number - Arrow thickness in meters. Default: 10
arrowHeadLengthCoef (Optional): Number - Arrow head length compared to the total length of the arrow. Default: 1/3 (third of the length)
arrowHeadWidthCoef (Optional): Number - Arrow head width compared to the arrow thickness. Default: 2 (twice as wide)
arrowBaseWidthCoef (Optional): Number - Arrow base width compared to the arrow thickness. Default: 1 (same width) - Since Arma 3 v1.97

fill (Optional): Boolean - true to draw color filled arrow, false to draw outline. Default: true

map (Optional): Control - Map control. Default: control 51 of the main map display 12

Return Value:

Array - Arrow reference for removal in format [idd, idc, ehId] or empty array [] on removal operation

Example 1:: Draw a semi-transparent, blue arrow with default geometry:myArrow1 = [_pos1, _pos2, [0,0,1,0.5]] call BIS_fnc_drawArrow;
Example 2:: Draw a wide, green arrow outline:myArrow2 = [_pos1, _pos2, [0,1,0,1], [20], false] call BIS_fnc_drawArrow;
Example 3:: Draw a thin, red arrow with custom head geometry:myArrow3 = [_pos1, _pos2, [1,0,0,1], [1,1/5,5]] call BIS_fnc_drawArrow;
Example 4:: Remove the arrow created in Example 3:myArrow3 call BIS_fnc_drawArrow;
Example 5:: myArrow1 = [[100,400,0], [200,500,0], [1,0,0,1], [20], true] call BIS_fnc_drawArrow; myArrow2 = [[400,700,0], [300,600,0], [0,1,0,1], [20, 1/3, 2, 2], true] call BIS_fnc_drawArrow; myArrow3 = [[600,700,0], [400,900,0], [0,0,1,1], [20, 1/3, 2, 0.5], true] call BIS_fnc_drawArrow; myArrow4 = [[100,100,0], [200,200,0], [0,0,0,1], [20], false] call BIS_fnc_drawArrow; myArrow5 = [[400,400,0], [300,300,0], [1,1,1,1], [20, 1/3, 2, 2], false] call BIS_fnc_drawArrow; myArrow6 = [[600,400,0], [400,600,0], [0,1,1,1], [20, 1/3, 2, 0.5], false] call BIS_fnc_drawArrow;
