Stoping a units movement without altering the command que

Is there a way to prevent a unit from moving or null out its movement, without changing the units prior commands?

I ask as I'm seeing issues with teleporting units, where sometimes they are being thrown beyond the intended destination. Using self:SetImmobile(true) prior to the teleport doesnt help. The teleport destination is good as i can see the warp-in effects at the location selected. Just the unit (randomly) shoots over and past the destination.

alt-right-click (or was it alt-right-shift-click? I forgot) to remove the movement command's path node it's executing?

@resin_smoker There's already a key bind for that regarding engineers. I think it also works on units loading into a transport, but don't quote me on that.

Thanks but, maybe i should of mentioned that this is being performed within the units lua, not via the games UI.

Have a look...

You can retrieve the navigator and call AbortMove, see also the implementation of the hotkey in the sim side.

@jip Weill I'm not trying to cancel a move per say as I am attempting to keep the unit from being thrown as a result of a bad teleport. Maybe I should make a video as its rather hard to explain.

Video of the error: https://youtu.be/qOmSMJ8YfSE

In the meantime, I'll try using self:GetNavigator():AbortMove() as you've suggested.

No dice with self:GetNavigator():AbortMove()....

Looks like I may need to create a safety code to ensure the unit doesn't get thrown under the ground. Possibly to recall it to its original position, or outright destroy it.

Ok correction.... Performing self:GetNavigator():AbortMove() before the Warp, not afterwards is whats required. Not seen it fail yet but I may need to script in a function to remove it from under the ground, should it get stuck.
