[Solved] why doesn't this work?

[Cheshire]

hey there,

this trigger seems pretty straightforward and I can't figure out why it won't work. It's a spell (based on channel) that is supposed to cancel whatever the target building is doing (upgrades/research/training units). (the last line is just to make it undetectable to the owner of the unit).
would be happy for any help. thanks!

• forgetfulness
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Forgetfulness
  • Actions
    • Selection - Select (Target unit of ability being cast) for (Owner of (Target unit of ability being cast))
    • Game - Force (Owner of (Target unit of ability being cast)) to press Escape/Cancel
    • Selection - Clear selection for (Owner of (Target unit of ability being cast))

Hi,
the reason why your trigger does not work is because selections do not happen immediately, so the trigger forces player to press escape before he has the building selected. An option would be to force player to select the target unit, then create another trigger with "Player - Selection event" event and in this second trigger force the player to press Escape/Cancel and clear his selection.
But even then this is noticable (you can see the selection happen), also clearing selection would make for bad user experience (imagine you are controlling your army in a fight and suddenly your selection is cleared for no reason).

Anyway, there is a more efficient, but hidden way to do this - issue a "cancel" order to the target unit. Afaik that can only be done by using an order id, instead of order name.
Something like this:

• Untitled Trigger 005
  • Events
    • Player - Player 1 (Red) types a chat message containing a as An exact match
  • Conditions
  • Actions
    • Set VariableSet unit_var = Barracks 0000 <gen>
    • Custom script: call IssueImmediateOrderById(udg_unit_var, 851976)

The variable unit_var is a "unit" variable. Do note that in the custom script variable names must have the "udg_" prefix, so "unit_var" in gui becomes "udg_unit_var" in custom script.
The second argument in the custom script is the order id of the cancel order. You can see the full list of order ids here: Order Ids

If you want to cancel the full queue, you can just place the custom script in a loop (here the "i" variable is of type "int"):

• For each (Integer i) from 1 to 7, do (Actions)
  • Loop - Actions
    • Custom script: call IssueImmediateOrderById(udg_unit_var, 851976)

thanks!!!
this is immediate, so I don't need to worry about MUI, right?

selections do not happen immediately

-so for future reference - what do they wait for to happen?

Yes, you don't have to worry about MUI.

-so for future reference - what do they wait for to happen?

I don't know. It may be because its related to user interface that its not immediate.

For each (Integer i) from 1 to 7, do (Actions)

what type of value do I set to this integer?

 

[Nichilus]

You don't need to set any value (the loop itself changes the variables value from 1 up to 7). Actually the variable plays no role here, you may as well use "for each (integer a) do" action.

works like a charm. thanks!
