[Spell] Dig - Need some help, xD

[Mike889]

EDIT:Hmm... Now i'm thinking burrow will never work, because i tested only the burrow, unburrow with no special effcts, and... well, when you burrow the hero loses all of his skills, making it impossible to unburrow. =/ Do you have any suggestion about other skills to use?

Well, hello guys!
I'm making my first spell, "Dig".

The Royal Guard digs up a hole on the ground and hide himself allowing an improved hitpoints regeneration. Also, if an enemy hero comes next to your hole, it is trapped and stunned for (2xSkillLvl)|n|cffffcc00Cooldown|r|n|cffffdead:10 seconds

But i'm having some trouble. First, i don't know how to make the stun effect trough a trigger. But, well, this is not the worst part. The real problem is making the "enemy hero comes next to your hole".
I based my ability on "burrow", so my hero is burrowed. Next i did the trigger, and a Point right on the caster. Next i made a dummy unit, so i could store it on a variable.
Next, i made another trigger. The event is: A unit comes within 200 of "unit".
I can't change this unit to the dummy unit i stored on the variable!
Here is what i currently made:

Dig
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Dig 
    Actions
        Set DiggedHole = (Position of (Triggering unit))
        Unit - Create 1 Dig Dummy for (Triggering player) at DiggedHole facing Default building facing degrees
        Set DiggedHole_Reg = (Last created unit)
        Custom script:   call RemoveLocation( udg_DiggedHole )

@Edit:

I don't got WE open right now, but just set the Hero's skills in some variables, and when he have done the ability just add the variables to his skills..

 

[Drunken_God]

you have to add the event in your casting trigger

Simple

Assuming that only 1 unit is allowed to be stunned at one time

The lazymans' way:
Event:Unit is within 200 range of "Underground Dummy hero" ( if hero is not on map , have another trigger set it as a varible)

ConditionVariable:integer)Hero underground is equal to 1 ( where 1 is yes , 0 is no)
So if unit uses underground skill, set it to 1 ( remember set variable(player number(owner of unit).

--This means that after the hero uses the skill , it changes to ur dummy unit , then it sets to 1. After it uses a skill for example , resurface , set it to 0--

Condition2: And

(Variable:interger)Stunned is equal to 0 ( where 0 means no other unit is stunned and 1 means that a unit has been stunned already and so other units cant be stunned)


Action :
If...Then...Else..
If : Triggering unit belongs to enemy of((owner of (Dummy unit)) equal to true

Then:
Set (varible) stunned to 1
Pause triggering unit
Special Effect - Create a special effect attached to the head of (Triggering unit) using Abilities\Spells\Human\Thunderclap\ThunderclapTarget.mdl
wait 10 seconds
Unpause Triggering Unit

For the triggering unit , if there is an option which fits " Unit within range" , then use it cause i dont know bout it or i missed it

But i think there isnt ... the safer way is to make another trigger:
Unit within range 200 of dummy hero

Set stunned unit(Player number of owner of "(Variable:Underground dummy hero)" to triggering unit ( this will give the trigger only 1 choice as it can only select that one unit)

then replace triggering unit
