Why don't you want to use the base impale ability?
What other requirements does your spell have?

it's hard to make it have a custom trigger damage
because of it's air time makes the targets invulnerable

You could time the damage to only happen on landing ( (distance/speed) + 1 ) sec

the other side effect of impale is that if you move it will stop going, it is channeling, thats why dota's impale is Channel-based spell
he means
but it works)
he means

the u and u2 are globals but if you have global with name u and you do local unit u and you want to do like i did cause u to damage u2 it will first check if there are locals with name u and u2 then globals(I think thats how it works, if not then sorry
so the damage will be occurred after 5 second?
and did it will damage all target?

You'd have to add units in a rectangle angled from the caster to the target point, and damage each unit in it individually.

do you want it in GUI or Jass?
this damages noone acually
GUI please
that what i was looking for, how to do that

You want just the targeted units in a line in front of the caster to be damaged (no air lifting)
or you want it to be just like impale, (air lifting) but without the Invulnerable thing?

The easiest would be to make a dummy unit that casts shockwave with 999999 speed.
The angled rects method requires some maths that I don't quite want to think about right now.

Don't see why you'd need or use either of those, much simpler to use a short mathematical loop to select all units within a line of a given thickness and control what makes them selectable targets with triggers, example:
Note: may not be 100% accurate because I typed it out, rather than making it in the WE, but I think the idea is pretty clear, also note that some of the things are constants which should be controlled in a configuration elsewhere.
Additionally, I would've used locals when appropriate, but there's no point confusing a guy
Edit:
Now onto the subject of creating the rest of the spell, after you've either set up with dynamic indexing or hashtables you need to run a periodic trigger which runs every 0.03 seconds (turned on by the first trigger which runs when the spell is cast like my example) and then checking if either the array is empty or there are no units in the unit group, again depending on method. Then you proceed to add lots of tasty other variables which account for everything you'd need to add height, special effects on the like as well as probably needing to pause the unit so it doesn't go running off while flying up into the air, if you don't want flying and just want damage, then none of this is needed, you just deal damage and empty the unit group at the end of the spell and don't bother with indexing, since it'd be pointless and use the unit group method, really explaining exactly how to go about making the loop work, would be making the whole spell with text, and then sending you off to recreate it, which would kind of be redundant, so I'll stick to this short explaination:
You increase the unit's height until it reaches (height) then you decrease it, and when it hits 0 you damage it (or on the way up if you'd like) this will require an increment speed variable, decrement speed variable, boolean (up or down) and an accelleration variable for speeding up/slowing down (prehaps two if you want greater control)

sorry but i quiet dont understand this part
and did DotA using a custom Impale too for their skills(because in DotA unit that impaled by lion can be attacked while they are still flying)

If i get it right, he wants an impale that will not make units Invul. while they are airborne.
I have tried, picking up the targets of impale, and
IMO this will require what Commander has posted, plus making the targets fly manually, adjusting their height, AND creating the Impale special effects and stuff in a loop.
Taking the above as consideration what you want is too resourcefull, requires a lot of time doing it, and is not worth the trouble.
Its half a second anyway, the invul. part...
PS: Commander +rep for your example, it may come in handy some day, and it would definitely take me some time to think it.

I'll explain the individual parts:
This bit you make sense of, so not much point talking about that
This part is to work out how many times we need to run the index to grab all the units within a line of the given range (Range) being how far to go, (Aoe) being how much distance we cover part index
Distance is increased to move along the "line" by the Aoe range, TempPoint3 is to get the new location of the distance we need so we can then use it to grab nearby units with the unit group
All of this is to just add eligble units into the spell for the impale to effect by running tests on the unit, and the rest is removing leaks
just to make sure,
the range variable is the maximum range for my spell right?

Yes, and AOE is the thickness of the line you want

i have done what you said earlier, but there is something wrong in this part
some units at the max distance are not damaged
maybe because my max range=380
and the Aoe=250
so 380/250 only cause 1 loop and any unit beyond 250 will not be damaged because they are not involved in the loop
any idea to fix this?(except by changing the max distance and Aoe)

You needed 250 thickness? That's one thick impale, well all I can suggest while keeping the triggers the same would be to either follow what Eubz said, or to change the values I'm afraid. And Eubz's method will change the max range, whatever your Aoe is "needs" to be a factor of the range, or the looping will be inaccurate one way or another.
However: There's another way to do it, which woud be to introduce another variable which would be like "search distance", so you keep to AOE the same but do this instead:
{}OOOOOOO
{} being the caster
O being the target selection areas
it'd select with a lot of overlap (each circle will have half of another circle in it) which hence why I put in the "is it already in the target group" condition in my example. so that it wouldn't re-add other units or units directly on the line between the circles in the first method. I'll work, but it's less efficient use of space.
