Help - Siphon Mana + Explosion

Plunders · Sep 16, 2013

Hey guys, i'm having some trouble with this trigger:

Event
Unit - A unit finishes casting an ability
Conditions
(Ability being cast) Equal to Siphon Mana
Actions
Special effect - Create a special effect at (Random point in (Region centered at (Position of (Targeted Unit)) With size (300.00,300.00))) using <Special effect>
Special effect - Destroy (last created special effect)
Unit - Make triggering unit invulnerable
Unit - Cause (casting unit) to damage circular area after 0.00 seconds of radius 300.00 at (Center of (Region centered at (Position of (Targeted unit)) with size (300.00,300.00) dealing 300 damage of attack type spells and damage type universal
Unit - Make Triggering unit vulnerable

The

Unit - Make triggering unit invulnerable

is for security reasons, and has worked well in other variations (the damage and effect being at casting unit, instead of targeted unit).

But in this variation it gives the following bug:
1: Makes a special effect at a fixed point of the map, not on the target unit.
2: The aoe damage never comes, but often my hero will die instantly after casting the spell, and he has more than 300 health i assure you...

Do you know what i can do to fix these 2 things?? keep in mind that i do not know how to set up variables and putting them into work in triggers (to messy and complicated to understand), so keep it simple.

Hope you can give me a hand
Yours truly
Mr. Plunders. :ogre_hurrhurr:

#1
"(Targeted Unit)" is a response to the event "A unit acquires a target" not to a "Unit finishes casting an ability" event.

#2
When "Unit finishes casting an ability" event fires, there is no longer any point of ability being cast, no target, no nothing. You will have to save the target into unit variable when the caster "starts the effect of an ability" and then when the caster "finishes casting an ability", you create the effect at around the unit you saved beforehand. If you want to make this MUI, you will have to learn indexing and deindexing to prevent bugs.

#3
As far as I know, Casting unit = Triggering unit, however using Triggering Unit is faster

#4
You damage everyone via the "Damage circular area" - even allies of the caster. If that is not your intention, you will have to create unit group by picking nearby units and filtering through them to pick up enemies only.

#5
You leak locations (and maybe even regions)

(Random point in (Region centered at (Position of (Targeted Unit)) With size (300.00,300.00)))

This is terribly wrong. You have to learn how to
1) clear leaks and prevent leaks - look here: http://www.hiveworkshop.com/forums/triggers-scripts-269/things-leak-35124/
You basically have to save the location beforehand and then create special effect at that saved location and then remove that location.
2) Don't do it the way you did when choosing random point, use polar offset instead - you save the location of the target and then create and save new location, offset by <random number between X and Y> and at random angle.

Hey there really like your response! I have to write a report today, but i'll be sure to see if i can learn something from the guide and your wise words in the evening.
in other words, check in tonight, might have a new question

Thanks a lot so far.

Split this in two triggers do the setup of global variables: SM_effect, AM_Area, SM_Damage on map initialization as they are constant.

I think it is not needed because it is actually a demo spell he can split it into two triggers as he wanted

Oh my god, you actually made this

I'll have to study the whole Variables theme, i will try my best to learn it, but know that it might be too complicated for me, so i might fail.

I'll read some guides and work my arse off, if i should succeed in understanding the triggers and advices from you and Nichilus, i will +rep you both. Seems you put a LOT of work into this.

Thanks for helpful hints so far

Thanks for the link really

now i can understand the trigger Jake sent me, thanks a lot Nichilus!

Now Jake i get why you ask:

"Actually making the caster invulnerable and vulnerable in the instance cast or executing cast is seems pointless."

"because you add the caster a invulnerable then you make it vulnerable."

But know that i used that because i didn't really think i could filter the damage, now i know otherwise.

Thanks you guys for the help, i wanna +rep you both, it says i need to spread more rep to give it to you... So i gotta answer other peoples posts or?

- Plunders

PS: Now that i read a basic guide on variables, i feel stupid over having had such a problem with understanding it.

It is okay if you don't rep or credit us because we are happy in helping others without expecting in return

Here is the map with the spell Jake..
(know that being forced to share an incomplete map really annoys me, but i guess i can understand why you need to see this...)
You'll see that i use the exact trigger that you gave me... Anyway, the spell is called "siphon soul" and it's the last hero that has it...
