Pausing unit training through triggers

Hey, I was wondering if there was any way to pause unit training at a particular building like what happens when the food limit is reached. I tried a variation of the freezing breath ability, but that completely pauses the building and units cannot be cancelled or added to the queue. Thanks in advance for the help.

have you tried with the action: Unit - Pause Unit ?
but i don't know how it will affect structures that is training units.

Doesnt help. does basically the samething as the freezing breath.

this is 1 of the most compleicated triggers i have helped with but here is the answer
its much easier making it happen by a unit attacking the structure with the frost ability but the frost abilty makes no effect but stops construction and make the attacking unit with no attack

here is a few triggers when working toghter will do what you want...

Events
You pick your event (such as every 600 seconds ect)

Conditions
No conditions unlss you want them

Actions
create 1 dummy attacker at position of unit(i.e the building but make sure the unit is invisable...use the model file Zone indicator (custom campaign) )

wait 2.00 seconds

or last created unit to attack (the structure and remember the unit attacking must have the ability, be able to attack but the lowest it can and the unit is invisable...

if you think i dident explain it very good please pm me

Ehh, Mad-ness that would only make the building loose hp... (?)

No I dont think it will work with spells. Does anyone know anything about how the food system pauses production?
