Does starcraft2 use navmesh A* or grid A* for pathfinding?
If you want to see slides from James Anhalt's GDC presentation on SC2 pathfinding (and have some time to wait for a long PPT download), you can get them from here.

.
A* is an algorithm while a Navmesh is the data structure (graph) representing your terrain. Thus SC2 uses both, A* and a Navmesh, and steering behaviour on top of that.
Anyway, I wouldn't try to learn from what Blizzard is doing with their games. They're really just not that good except for their marketing and cinematics team.
Your question doesn't make sense.

His question makes perfect sense. He was wondering if A* was used on a *navmesh* or on a *grid*.

Wow... Ok...

You went 0-2 on this post.
1) Read the person's post before you bust out the snark.
2) You are knocking arguably one of the best game design teams in the history of ever.

It uses a navmesh. Also please note that there is a bunch of steering code happening in there rather than simple A*.

The ppt zip is broken, I cann't open it.

Sigh. That's the one hosted on the GDC Vault site. Let me see if I have my own copy around here someplace.
Could you sent me the "James Anhalt's GDC presentation on SC2 pathfinding", thank you very much
