Ok, so I've seen a few people asking if there was some other way to detect a unit's direction without mobile grids ( don't know why ), but here is what I made. It works almost perfectly and is very precise; however, it will slightly slow down the unit, but it's not by that much. Move around Hunter Killer ( I centered on wrong location ) Also create a zealot and control the green dot on your minimap =D

I also hope this isn't already a method posted a long time ago.
( Note: Pain in the butt to make this. Everything I have would have to be almost exactly like what I have in order to recreate this )

It can be done without unit slow down and with only locations.

Yes, but people didn't want to use mobile grids for some reason. As I mentioned. Unless it's a method I'm unaware about.

I suggest reading through the entire thread, as there is a lot of valuable discussion.

Ya if anyone wanted a good one they should use that; however, depending on their map they wouldn't be able to. So I could see people not wanting to use it because I believe you would need a location for every square of your map. Correct me if I'm wrong.

You're wrong. You just need as many locations as the number of pixels your unit can move between trigger loops.

How do you find how many pixels a unit has moved every cycle?

Add more locations till it works.

EDIT: NVM. I found the strafe arena and I'll just learn off of it. Although, I do not have the slightest idea of how to make a mobile grid using this. Such as moving it around the map. If someone wouldn't mind giving a brief explanation, it'd be nice.

Honestly, I wouldn't recommend it. It wasn't meant for people new to it to learn from, so it'll probably leave you more confused.

There are three good methods to do what you're trying to do, and they all cause no slowdown and can be pixel accurate. Here are concept maps that are easier to learn from:

and location grid scanning, which I can't find a map for, but it and other methods are explained here http://www.staredit.net/wiki/Unit_Coordinate_Detection
