[Solved] Uncancelable Ability?

[ThompZon]

I have a spell where I want the caster to be "locked up" in an animation for 0.4 seconds or so, being unable to be cancelled by spamming move-orders and also not being cancelled by stuns and such. Is this achiveable?

Current setup is a channel-based ability with Follow Through Time = 0.4 and most other things standard

Spoiler: Details

I set the animation after a 0.0 timer delay, like so:

Spoiler: Set Animation

• HHNinjaStrike
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Ninja Strike (channel, Target point)
  • Actions
    • Custom script: local timer t = NewTimer()
    • Game - Display to (All players) the text: Begin
    • Custom script: call TimerStart(t, 0.00, false, function Trig_HHNinjaStrikeAnimation_Actions)
    • Custom script: set t = null

• HHNinjaStrikeAnimation
  • Events
  • Conditions
  • Actions
    • Custom script: call SetUnitAnimationByIndex(udg_hh_hero, 8) // Play Attack 2

This works, but is cancellable by the player and by stuns.
Is it possible to prevent it from being cancelled?

Simple but kind of messy solution is to pause the unit when it successfully casts, and unpause 0.4s later.

Enable the "Disable other abilities" flag (Object Editor). Then the ability becomes uninterruptable.

maybe something along the lines of:

• casts
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
  • Actions
    • Unit - Change ownership of (Casting unit) to Neutral Passive and Retain color

• finish casts
  • Events
    • Unit - A unit Finishes casting an ability
  • Conditions
  • Actions
    • Unit - Change ownership of (Casting unit) to Player 1 (Red) and Retain color

obviously add condition and maybe change the event, but something generally like this would be my idea. also consider neutral hostile or the alliance of what player assumes control.

edit: also add hero to selection of player b/c it will deselect when you change ownership

Stun the caster before playing the animation and remove the stun once you're finished. BlzPauseUnitEx() comes to mind.

Cool, I'll try a few different solutions out and see how well they work

Edit:
So I Tried the easiest solution first: Disable other abilities=true.
This seems to work as I hoped, meaning that I cannot cancel the order and stuns during the animation does not cancel anything and the stun continues as expected after the animation finishes. Selection is not messed with (as an ownership change would).
Only known side-effect (so far) is the unit buttons (abilities + move, attack etc.) disappear during the cast, but that's fine.

Edit2: Other side effect maybe to be "Pause" unit, meaning buffs etc. does not count down?

Thanks

Pausing units has a few unwanted side effects which you can read about here: [vJASS] - [Snippet] SuspendUnit

BlzPauseUnitEx() is different though and acts as a stun: [vJASS] - PauseUnitEx

But if you don't care about the side effects of Pause then by all means use it.

Does the "Disable other abilities=true" on the channel cause a pause?

 

[Uncle]

Does the "Disable other abilities=true" on the channel cause a pause?

Yes, I'm pretty sure it literally calls the PauseUnit() function.

 

[Tasyen]

Nah, the "Is Unit Paused" function does not return true for units using a channel with "Disable other abilities", nor does it stop buff expire.
