Need help on a trigger

This trigger is driving me mad

Ok I need a trigger to start taking life away from a unit when it uses the Submerge (unit dives and stays in water) and stays submerged, and I need it to stop taking life when it uses the ability Surface which brings it back on the surface

any ideas?

Here is what I started with


Events
Unit - A unit Begins casting an ability
Conditions
(Ability being cast) Equal to Submerge (Royal Guard)
Actions

I would probably do something like this (I don't know...I may be using too many triggers)

Event-
A unit begins casting an ability

Conditions-
ability being cast equal to submerge

actions-
Set SubUnit = triggering unit
Turn on (second trigger)
Turn on (third trigger)


SECOND TRIGGER:

events-
every 2 seconds of gameplay

conditions-
N/a

actions-
Set life of SubUnit to life of SubUnit - 8

THIRD TRIGGER:

events-
a unit begins casting an ability

conditions-
ability being cast equal to surface

actions-
Set SubUnit to FALSE
Turn off this trigger
Turn off (second trigger)

That's probably way too many triggers, probably could do it a whole lot easier if Submerge had a buff
Anyways, it's the best I got, it should work...knock yourself out

yes

I was figuring I needed 1-2 more triggers to help it flow

and I need to set the variable thats what I was forgetting

Thanks

No problem, I warn you, it may not work...highly unprobable, but it may...I'm only an intermediate triggerer.

hmm this trigger will definitely work

but I can't find the Surface ability in the list for the trigger,

I know its named Surface because I checked in-game

anyone know where it is?

Ahh I see, it's not another ability, it's the "turn off" function for Submerge, so change your Event and Condition of TRIGGER THREE to the following:

event-
a unit is issued an order with no point

condition-
Issued order equal to unsubmerge

that'll fix it =)

Thank you
