I need help on figuring distance

i want to create a spell called early warning. and i need help. i dont know how to make it check how fark Hostile unites are from the hero.

the ability is going to show a green ! above the heros head. and if hostile enemies are close it turns yellow. then when there close it turns red.

i dont know how to make it check distances PLEASE HELP

Well its not actually a case of the hero checking the distance, but the game checking it. You have to create regions around the hero. I suggest 2 regions around the hero. Set them both to different variables. Then make 2 triggers that identify when a unit enters one of the regions. Then u need another 2 triggers to identify when a unit leaves a region and how many units within each region, inorder to turn the "!" back to green. This is just a brief overview. It might be a bit complicated than what i have said, but its close enough.

Hope this helps.

thanks for the hellp. but i have a question about that

will the regions follow my hero? o_O

or do i have to make it, if so how?

Isn't it easier to use the Event 'Target Unit comes in range of Target unit'? With a condition meant for Hostile units?

hmmm... sounds like it might work, ill check it out thanks

cant find a trigger that classifies a unit as hostile (enemy players AND creeps) :(

Events
Unit - A unit comes within 256.00 of Footman 0000 <gen>
Conditions
(Unit-type of Footman 0000 <gen>) Equal to (Random level 1 creep unit-type)
Actions

I think this should work... excluding the action of course.

would this work for enemy units (player 1 player 2 on aand so on?

No, this only worked for 1 unit... err... sorry, I guess I thought it was for 1 unit only :(

tsall right, it might not even be possible..... :>

but it would realy come in handy in one of my maps

I'm sure it is possible but I got a feeling it just slipped my mind... Oh well, more things seem to slip my mind :P

Sorry anyway

if u get any ideaaas about hot to go about doing this, please post !!! ^_^

A slight revamp of Fladian's triggers:

But Shimrra, that only works for 1 hero, right? Or does it work for all heroes right away?

ill try it out, and see what it looks like thanks !
