In order to change the behavior of a unit currently following a string of waypoints, it is not enough to use deleteWaypoint. The path of the unit is calculated by the waypoints present at start, and the unit will continue according to the original waypoints even if you delete them by using this command.
To achieve the wanted effect, you should rather use setWPPos to the units current position (thereby stopping the unit), and (after a small delay) use [[deleteWaypoint]] to remove the [[waypoints]].

When you want to remove all waypoints, do '''NOT''' iterate over ''waypoints _group'' while trying to delete them (an array is by reference!). Instead use an approach like this:

Description

Description:
Removes the specified waypoint.
ⓘ
  • When a waypoint is deleted, all other group waypoints are immediately re-indexed. See Example 2 for a deletion of all group's waypoints.
  • Deleting a group's current waypoint will not stop the group on its tracks.
Groups:
Waypoints

Syntax

Syntax:
deleteWaypoint [group, index]
Parameters:
group: Group
index: Number
Return Value:
Nothing

Examples

Example 1:
deleteWaypoint [_grp, 2];
Example 2:
Because waypoints get immediately re-indexed when one gets deleted, delete them from last to first:
private _group = group _unit; for "_i" from (count waypoints _group - 1) to 0 step -1 do { deleteWaypoint [_group, _i]; };
or always delete the first one (if you want to delete them all)
private _group = group _unit; for "_i" from 0 to (count waypoints _group - 1) do { deleteWaypoint [_group, 0]; };
or use forEachReversed:
{ deleteWaypoint _x } forEachReversed waypoints _group; // Arma 3 v2.14+ only

Will stop the group where it is and delete its waypoints.
