Description:: Sets a polyline marker's path.
ⓘ
Multiplayer optimisation: Global marker commands always broadcast the entire marker state over the network. As such, the number of network messages exchanged when creating or editing a marker can be reduced by performing all but the last operation using local marker commands, then using a global marker command for the last change (and subsequent global broadcast of all changes applied to the marker).
Groups:: Markers

Syntax:: marker setMarkerPolyline path
Parameters:: marker: String
: path: Array - [x1, y1, x2, y2, ... xn, yn]
⚠
Be aware that this command expects an array with a minimum array size of 4 and that the array count always needs to be dividable by 2 and return a whole number.
Code: count path >= 4 && count path mod 2 == 0; // true → valid path
Return Value:: Nothing

Example 1:: Changes "marker_1" into a polyline and draws a sine curve on your position"marker_1" setMarkerShape "polyline"; private _return = [] ; for "_i" from 0 to 100 step 0.1 do { _return pushBack (_i + getPosASL player#0); _return pushBack ((sin (_i*10))*10 + getPosASL player#1); } ; "marker_1" setMarkerPolyline _return;
