Spell making help please!

Ok I asked this question a while back and got plenty of responses, but none really made much sense to me. So here goes again, hoping that maybe I'll get some easier to understand responses.

My spell is an impale that after impale is finished the impaled unit(s) is/are entangled by a dummy unit. I can figure out most of it, but what I need is the condition for a unit has specific buff, what unit am i supposed to use? Picked unit? Target unit of ability being cast? I don't know! I'll post what I've got so that you may get a better understanding of what I need.
Thx to anybody who helps!

Seriously, if it takes so long to get an answer, why dont you just try it.
Target unit of ability being cast should work.

I got plenty of answers! I just didn't really understnad them as well as I could have now! Thx, I wasn;t sure if target unit of ability being cast would work since you don't have to actually target a unit for impale to work.

Picked unit should only be used inside the Pick every Units action.
Because thats the only place it will work.

EDIT: Impale wont work as well for Target Unit of Ability being cast.
If you target the ground, units will be hit but your not targeting anything.
And Target unit will only be 1 unit, not every unit effected.
You will need to pick every unit in impaled area and loop them being entangled

What does he mean by "entangled" after the Impale? And yeah, like infrane said, if it takes too long for someone to reply, just keep on saving your map, test the map to see if you have it, Exit Program if you don't and repeat. That's what I usually do when I'm making a custom spell, and it 95% of the time works :)

He means, he impales a area/target, once all the units have landed from impale, they get entangled, like the Nightelf hero spell.

Since I have found no way of doing what I need I've decided it would be easier if I just made a graphically enchanced impale. I was working in GUI, but working in JASS from scratch doesn't seem too easy.

If you have a lil' mor xp you will not think anymore "Oh my goodness is this hard to do" as mayn GUI guys ften say, you will just think "How will this be fastest, logical the best ...".

Well even though I've been tinkering around with it I just couldn't find a way. I tried alot of stuff except adding the units to a unit group and then having a dummy unit entangle them all but I don't know if that can be done to what I want it to.

Try using the condition - Boolean - Unit has buff (impale) and have the dummy cast entangle on all of the units with the impale buff on them.

Tried it, couldn't find a way to make the dummy unit cast on them, even though I did use "Unit has buff(impale)" in almost every trigger I tried.

So why are you using impale again? I don't like that spell cause of all the effects it has. I suggest using Breath of Frost.

Also, post your triggers cause what that above me stated should work.

Edit: You said you wanted a graphcially enhanced Impale. Couldn't you just edit the buff for impale (or stun, your choice) to be entangle at the origin attachment point. I may have misunderstood you though...

The spell is the units are impaled then entangled by a dummy unit. And yes, I know stealthfox's method would work. I'm saying I don't know HOW to make such a trigger. And I don't have the triggers anymore. I got rid of them after never figuring it out. Whether this was smart or not, it's too late now. I'll try to work on it more, but GUI is too limited and I can't do JASS from scratch. I'm mostly having trouble with the events and actions. I don't know which event to choose, A unit begins casting an ability, a unit starts the effect of an ability, and unit takes damage, etc. And actions are just, I don't know what actions to use to make the dummy unit entangle the Impaled unit.

You would actually need multiple casters for multiple entangles...or at least I think...anyways, use Vexorian's caster system and it can be done easily.

meh... i'll try vex's spell system. I've heard good things about it but I suck at JASS so it could make things harder not better for me. But I'll try it.
