Trigger Question

Plz guyz, I wanna know if there's a way of detecting if a unit's projectile hits a unit as it "travels" to it's destination, W/o using Shockhave of "Dash" based spells, becouse those ones walks over a fixed distance from the floor, and climb cliff and walkables things. Can this detection be done in GUI? I just don't have the time to learn JASS
thx

Well you dont give much information put if i got it right, i think you can use this?

please don't quadruple post. Removed the other ones

uhmm that's not what I want, let me explain myself better. I need a Unit to Shoot a bullet that will "travel" to that ability's max range. But I don't want that Bullet to climb cliffs (just like the "shockwave" spell do), so i'm asking if is possible to detecd if a unit's missile pass trough a unit w/o that unit being is target. I know that's possible with the "Particle System" and other ones, but I don't know jass, and i'm a little busy at the moment to do so. So I ask, can I detect the units that a missile crosses?

In short: no, theres no practical way to do that without JASS

By practical, I mean a way to design the system needed AND keep your sanity at the same time
