  • Windrunner's Powershot speed reduction multiplier against trees

    For the ones who may not know, Powershot is (or at least should be) slowed down as it hits trees and units.
    Its base speed is 3000, and it should be getting slowed down by 10% on each unit-hit and 1% on each tree-hit.

    Now, when I look at the npc_abilities.txt, I see only one speed_reduction value set to 0.1 for all levels. I see no 0.01 anywhere.
    With the new ALT tooltip thing that has been introduced, I can see that they know that it should be slowed down with the trees: http://i.imgur.com/Ow92dPE.jpg

    So... there are tree possibilities:
    - Powershot is not being slowed down by trees (since there is no reduction value for it in the abilities data file)
    - Powershot is being slowed down by the trees with 10% instead of 1% (since there is this tooltip in-game, assuring that they know about it, but since there is no special value for that in the files, it probably uses what is available)
    - Powershot is being slowed down by the trees with 1% properly (since the tooltip, and there is a high possibility that this thing might be rather directly coded into the code)


    I cannot test this stuff...

  • #2
    [00:56.43] Windrunner hits Nyx Assassin with Powershot for 150 damage (492->342).
    [01:06.29] Windrunner hits Nyx Assassin with Powershot for 150 damage (372->222).

    Not reduced by trees (although that doesn't really show much, just trust me ) So I am assuming they don't slow it either

    You could test if they slow it by using an instant cast to toggle something (like soulring) and check the time between soul ring activating (and cancelling the channel) and the arrow hitting, with and without trees.

    For heroes:

    [09:07.95] Windrunner receives Sacrifice buff from Windrunner.
    [09:07.95] Windrunner hits Nyx Assassin with Powershot for 79 damage (1118->1039).
    [09:07.98] Windrunner hits Nyx Assassin with Powershot for 71 damage (1403->1332).
    [09:08.45] Windrunner hits Nyx Assassin with Powershot for 64 damage (1403->1339).
    0.5 seconds

    [09:17.98] Windrunner loses Sacrifice buff.
    [09:20.35] Windrunner receives Sacrifice buff from Windrunner.
    [09:20.78] Windrunner hits Nyx Assassin with Powershot for 54 damage (1403->1349).
    0.43 seconds

    As you can see the first arrow hits the first nyx at 0 seconds flight time, and the second at 0.03 seconds flight time... (1-0.1)*(1-0.1) = 0.81 speed. 0.43/0.81 = 0.53, so I'd say within the margin of error.

    For trees:

    [15:47.39] Windrunner receives Sacrifice buff from Windrunner.
    [15:47.75] Windrunner hits Nyx Assassin with Powershot for 124 damage (1403->1279).
    [15:54.28] Windrunner receives Sacrifice buff from Windrunner.
    [15:54.65] Windrunner hits Nyx Assassin with Powershot for 119 damage (1403->1284).

    0.36 vs 0.37... Trees may or may not be affecting it... Inconclusive! [especially because the trees were in the first arrow, and it was faster..)
