[Trigger] Calculating distance traveled?

[kewlthis]

How should I do this? Periodic trigger sound best option for me, but it would pretty much require using global variables, which I dislike...

So I would like to know if there is some smart way to do this. I havent yet adapted to action/event/condition definition, so dunno if there would be somekind of function to help with this.

Periodic trigger is the only way to do it if you want to do it cleanly. You don't need globals. You can use units' custom values to store the information you need.

you dont need a periodic trigger if you use an action definition

The problem with the action definition would be:
That only counts distance between 2 points after duration, so it doesnt work properly if unit walks back and forth, but that gave me some ideas maybe I can use loop on there to store distance periodicly.

Ill have to look if I can get something done

Meh I need to know how to return value to variable from action definition. There is return option, but I dont know how to return it to variable....sight*

I did this meanwhile...I dont know how to use the return function so I used global variable to transfer values. The triggers work, but cause lagg. It runs like 500 events/actions in half a minute, which seems to be too much.

*edit*
Doh...I had another triggers running too, will see how it affects....

*edit2*
Yea it works. But I REALLY NEED TO KNOW HOW TO USE THE RETURN FUNCTION!!! HELP MEEEEEEE
