[Trigger] Check if there are units/obstacles on your way

[Majin]

Hi,
I'm trying to do a charge spell that stops if there are some obstacles (trees, portals, walls, buildings) but keeps going to the target if there are other units on your way. Till now i went up with making a group with units around the location you have to reach and if it's not empty then it will turn off collision for the unit (if it's empty instead it'll turn on collision). As you've already guessed, this doesn't work that great, if i make a too little region then i have troubles with big units (such as abominations), if i make it too big then it'll charge units towards thin obstacles (walls, portals). i know this is because triggers consider a unit in a region only if its center is inside

Any idea on how to make this work?

You can check if it's walkable or no.

How?

You can check out this code which is a way to check that using items. It seems quite stable to me

The bad news is that you have to use coordinates, not so suitable for GUI. But you can use GetUnitX( unit ) and GetUnitY( unit ), or GetLocationX( loc ) and GetLocationY( loc ) to solve that.

EDIT: Thanks to Vexorian for the function

Dude, he done said Trigger, not JASS.

The way you said you've tried is the best way to do as far as I can think of. You can do the same for destructibles. There's no need for regions, but just check if there's anything in range.

i didn't say anything, i do it both ways (GUI and JASS) well actually i do it 3 ways including vJASS i'm slowly learning. i put the trigger tag but i wasn't specifically looking for a trigger, any solution would've been good for me. I think i just forgot to write i've solved it with Vexorian's function though i think maybe a unit with perma windwalk created at the start of the map could be more efficient
