How to make player unable to control unit for a duration?

Well, I am making an ability in which unit has to be moved by triggers and is playing "attack walk stand spin" animation. I move unit by SetUnitX and SetUnitY calls and I play animation using custom ability which is based on armor bonus and just has "Art - Animation Names" field set to "attack walk stand spin". It works pretty fine however if player orders unit to move during the ability is being used (it is a dash ability) the unit will stop the "attack walk stand spin" animation and will play standard "move" animation. I want to make player unable to control casting unit during dash. I also want to avoid:
-pauses
-changing owner
-removing from selection
-stunning/snaring/hiding(?)
Ah and also I'm using periodic timer with duration set to 0.015
I don't use SetUnitPosition or SetUnitPositionLoc because animation won't play, even if player doesn't give the unit any order.

if you pause or stun unit no orders will pass.

i personaly not able to reproduce animation change with armor bonus, if you post map with demo ability-trigger we will see.

to change animation you can attach animation flag to unit and then set animation speed to zero.

Oh I forgot to say here that I already solved that problem, yes the animation flag was the thing that made it work.
