Gravity does not seem to do much, if anything, since pull 5340

[Enedin9000]

Ever since pull 5340 (https://github.com/DarkstarProject/darkstar/pull/5340), Gravity does next to nothing. I just tried again as a fully decked out RDM75 on a DC crab in Boyahda and either it does nothing, or very little. Video here: http://enedin.be/Gravity_test.mp4

Supernova server

Your server may need to update to fix a broken calculatePotency() line.

Not an issue with master, so nothing we can do.

Contact Supernova.

thanks!

(I'm on Supernova too)

This isn't an issue with old code (we're on latest DSP). It's changed in DSP too. It's a result of commit #5427, which reduced weight effect from Gravity spell from -50% movement to -26% movement, and Gravity II from -60% to -32%.

ffxiclopedia says Gravity is -50%. bgwiki says it's -26%. The -26% value seems like it comes from test by casting on players in Ballista in 2016.

It's harder to see a noticeable movement difference at -26%, and much easier at -50%. When I played retail, you could definitely see a difference when you cast Gravity, which makes me believe the -50% value is more likely. I haven't played retail in many years, so it's possible that retail Gravity's weight was nerfed at some point.

[TeoTwawki]

Also possible that the effects are diff between hitting a player and hitting a monster, or that it was 26% of a diff expression of movement speed.

Like 0-100 vs 0-255

base movement speed on the server might matter as well. whatchu guys got? (theres a setting for mobs as well as player - using stock?)

[wrenffxi]

Our base movement speed is +20% for players and mobs both, but I don't think it's any difference between DSP and Supernova that's the issue. I've tested on both. The code works in both cases. It's just the difference between the -50% it used to be and the -26% it is now. -50% is easy to see. -26% is less so, especially over short run distances. I believe in OP's video, there is a -26% movement, it's just hard to tell. I remember Gravity being more obvious, but these are very old memories.

[TeoTwawki]

honestly 26% in either direction should be pretty obvious, unless maaaaybe we're applying flat non % increases after it instead of before (I have not checked).

[Snugglesffxi]

our mobs set to +20% so i guess that would make our grav only -6%, guess that's why we can't see as it clearly.

nvm this is a dsp issue not sn specific.

[TeoTwawki]

maybe, maybe not. could still be something else. at work right now or I'd test the theory.

[wrenffxi]

It's not +20% - 26% = 6%.

Gravity slows a thing by 26% of whatever its base speed is. Our mob's base speed is higher than DSP. But it's a 26% cut either way.

[TeoTwawki]

The 20 isn't even a percent. its 20/255 added to the base of 40. I was questioning when that 20 gets added by DSP (again, let me point out this was conjecture without looking)

ignore everything I've suggested, somethin else going on entirely, see below

[TeoTwawki]

sooo I'm seeing mob speed being off even without grav involved...catching up to me while my movement is enhanced and theirs isn't. just a regular ol statue in sky, not a raptor.

[Enedin9000]

@wrenffxi thanks for getting involved

[wrenffxi]

Yup, I did a bunch of testing last night, and agree with Teo. The root issue isn't gravity -- although its power was lowered from 50 to 26, the 26 value's probably right -- but instead, it's that the mob moves so much faster than the player, that when it follows you it's essentially slowing down / capping its speed to the player.

So when it takes a 26% movement hit, you don't notice, because it's still capping or nearly capping its speed. It looks like the mob lags behind the player only because of the time it takes the client to be updated about mob's position.

So this issue should be reopened as something like what Teo said above: "mobs move faster than players with identical speed, and even players with enhanced mod::MOVE."
