    Requesting Pathfinding Examples

    We are working on improving the pathfinding of Dota 2 and could use your help. If you know of situations where the pathfinder in Dota 2 isn't performing as you would hope, please post to this thread with examples. We've seen a few really detailed videos that have been helpful so far.

    Thank you!

    While I can't reproduce it all the time, I have seen it happen a lot of times over the years and even a few months ago. See the screenshot [ http://steamcommunity.com/id/cvp_bg/...24952347691906 ].

    A hero can get "stuck" in there while moving out from the camp. When it does happen, you have to click a few times in random places to get your hero out of there or he will just stand there as if he is entangled.

    I have also had that happen in the small path in trees to the right of radiant mid tier2.

    In general, it can be annoying to cast or attack a target on different elevation. For example, a target could be in the river near the bot lane ramp, while you are in the jungle on the high ground. If you try to auto attack them but aren't close enough, you will path all the way around the cliff, when if you had manually moved up you could atttack then. I would love if there was an option to path to the nearest point where you can cast/attack a target rather then having to use the normal path finding. I can make a video to demonstrate the issue I have sometime tomorrow.

    Edit: This video shows how it can be inconsistent where the game knows it can just move up a bit to attack, or forces you to path all the way around to the target.

    Radiant Top Super Cliff:

    Sometimes when trying to ward the supercliff next to the top lane radiant T2 tower, depending on where you click to place the ward, and what side of the cliff your hero is coming from:

    http://cloud-4.steamusercontent.com/...369F943E353B3/

    Your hero will reach this point on the map and then stop moving:

    http://cloud-4.steamusercontent.com/...D45132F36B4C3/

    No error message is produced when clicking to place the wards, it's a completely valid location. Your hero just decides to not go the last bit of distance needed to get in range.

    I found a very similar (possibly the same) issue recently while trying stuff in a lobby. It seems like pathing sometimes fail to see wide enough open gaps as passable. For example if you trap a units between trees or a bunch of other units, but leave an about 25 range wide gap open, your hero sometimes won't walk through the gap, even though it can fit there with its 24 collision size.
    Please, just call me buny.

    is it only path finding? or is the glitching with moving fast around a tower/cliff/whatever included, where you always do mini stops instead of walking smoothly?

    Edit: Isn't it better for this kind of thread to have a mod/OP/somone collect all relevant stuff on the first page/in the first post, to make it more accessible?

    I'm not sure what the reproduction conditions are but I've fairly often had an issue with the dire ancient. I would have my hero move towards the fountain, and it takes a right turn around the ancient, stops halfway and then goes back around and goes the left way, hugging the ancient all the time.

    as someone who zones out/tilts out a bit and just start clicking across the map and letting go of the wheel, pathing fuck ups happen.

    Here's 2 older videos

    if you just click far away and let the game try to do its thing by itself something's gonna go fucky. I think I have more replays downloaded of this happening but they aren't labeled so it's gonna be hard to find.
