how make unit can't atk over tree wall

how make unit can't atk over tree wall.

i have a line of tree to block out movement and sign range of unit,
when i see unit over there, my range unit attack over the tree wall,

how i make them can't attack if blocked by tree wall
(the tree wall created randomly in game)

I don't think you can unless you replace all projectiles by dummy units with that model and order them to die when in range of a tree. But with a large amount of units, that'll cause a lot of lag. This method should probably only be used in RPGs. If you're making a different kind of map, you probably can't do this.

mayb that is the only way, (can't use in my map)

nvm i juz let it attack =.= (it look very fake)

You can do it via regions, but it would be not so efficient. When unit attacks another unit which is in other region, make him stop.

i have think be4, but as 1st post say, (the tree wall created randomly in game)(make by player)
so the direction is different in every game, too hard or imposible to create every region on the side and which way to which way, got block or not and many many....

It can be done checking, when unit attacks, if there is any tree in the path between attacker and attacked unit.

Actually, you can't. For as far as I know, you can only check for doodads in a region. And since you can't create regions, only move them, you can't shape them in the range and angle you need. And regions can only be created horizontally and vertically. So if the angle isn't 0, 90, 180 or 270, there's absolutely nothing you can do.

Yeah, but really small region is needed here which will move in a line where missile of unit has to go (from attacker to attacked unit).

and another problem if u use trigger to check it:
if you use trigger to check the region, let say if there have blocked tree,
you order it to stop???
then it auto attack again, then trigger stop again?

so the unit like jam at there??

That would be the result...
