In order to change the behavior of a unit currently following a string of waypoints, it is not enough to use deleteWaypoint.

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

To have the unit stop on the spot you need to set its current waypoint where it is and add a little delay, as stated above by Saintolaf so:
group _unit spawn { [_this, currentWaypoint _this] setWaypointPosition [getPosASL ((units _this) select 0), -1]; sleep 0.1; for "_i" from count waypoints _this - 1 to 0 step -1 do { deleteWaypoint [_this, _i]; }; };
Will stop the group where it is and delete its waypoints.
