If you would go via vision (unit vision or overall vision btw?) you would need to constantly check (whenever vision has changed) if there is a better path available. For every unit moving on the field. I currently dont know if it updates at all (i.e. when a supply depot is lowered / raised) or if unit just computes the path once. You go after what's known at the time you issue the move command. It would work just like it's working right now, except that you need an array for each player which would take up more memory. For example, if someone builds a supply depot out of your vision, your array which contains information about the map would remain unchanged and assume that it is still empty/walkable areas. | ||

Muta stacking and moving shot were not intended in Brood War, the difference is that in this game all bugs are patched pretty quickly once they're found, regardless of how they affect the game. | ||

I like the video, very educational. I do not agree with the people that are asking for a more entertaining video as the purpose clearly was to educate and not entertain. | ||

Any ramp on path nullifies the difference in patches "with" and "without" Nexus. you're both right, but then again with setting waypoints with shit is is as easy as hell to get those straight lines you need. just dont go there clicking at the minerals from your home base, but do it like in the video with adjustment regarding the terrain and voila: it is no problem at all. | ||

HON has nowhere near the number of pathfinding calls that SC2 does, and pathfinding failures are more noticeable in SC2 because players cannot devote their time to precisely controlling a single unit for the whole game. | ||

I'm surprised it hasn't been fixed since, though. It might become very relevant with the upcoming Gateway buff :\ | ||

HoN is not an input synchronous game as far as I know, this means they don't have this particular problem and if they did it was easy to avoid. Blizzard could hide subsequent path ways but the bug would still be exploitable, just learn where to click and pay attention to a texture detail on the map for reference, if the harvester deviates, there's an obstacle. Fixing it properly wouldn't bug the pathfinding, you just need to keep a view of the AI information for every team in the game. However this means that the CPU cycles used for pathfinding and the RAM used for holding the pathing nodes are potentially multiplied by the number of teams in the game (though they could share some of the memory by having "transient" nodes, but nvm that). This could push the hardware requirements of a FFA too far, but that's about it. | ||
