I found a couple of tricks with Starcraft's pathfinding (probably I'm not first but anyway ^_^). They allows you to:

- sneaky check opponents location and expansion
- in some circumstance know about destructible rocks fall

updates

- you can use any unit (not only worker) to do any of this
- "closed areas" include walled-in Terran's base, so you can know when supply depot is down
- difference in worst case (when I find opponent on 3th possible location) on Delta Quadrant is about 15 seconds compared to "normal" way to scout.

Yes, units having "perfect" pathfinding even though you haven't scouted has been known for a while.

Your trick of using waypoints to see if the worker paths slightly "off track" however is new to me, nice find!

I must say, his voice is quite sultry.

Iv been waiting for someone to put up a good video like this. Im sure pros could gain some cool advantages with this.

Well, this is pretty evil for cannon rushes and just scouting in General, I really hope Blizzard updates the path finding engine to fix this.
I don't think that this is meant to be, nor that it should be in the game.

Uhm wait 1 sec, so how much faster can you actually scout your opponent on a 4 player map like tal darim with this?

Wow, finding the expansion and main is pretty unbelievable. It takes a keen eye to notice the slight change in direction, but it will definitely be used in games if its not patched. Time to start using it myself!

Knowing that the opponent walled according to the scouting path of your drone is quite evident, but I had not thought at all about the other uses of the pathing system you describe, they are really clever!

Really cool, thanks for the video. I knew that the pathfinding could be exploited in terms of ramp blocks, but didn't think of the other applications brought up in the video. I'm not entirely sure which side of the fence I'm on in terms of if this should be changed or not, for I think it's kind of neat that players can use little tricks like this (BW was filled of random tricks itself, as we all know), but at the same time it's a bit... Broken.

Imagine some pro using this trick in a tournamentgame.. Ppl that dont know this trick will be hella confused and blame the pro for hacking.

Hope Blizzard will fix this.

I'm not sure. Probably difference is not large. But sometimes 3 seconds is a difference between "I'm in" and "marine is out".

This only works when there's a clear path between you and the obstacle you're trying to find, and that's not the case on a lot of maps. What I mean is that you need line of sight to your opponent's expo to "proxy scout" it.

The great thing about this trick is that your opponent won't be able to notice that he's been scouted unless he places a building near the ramp.

Terran and Protoss will be as easily spotted as Zerg.

Definitely. Any ramp on path nullifies the difference in patches "with" and "without" Nexus.
