Who knows where in the code gravity is rounded to 0 if the value is very small
Avatar
deen 2024-11-14 10:01
I'm guessing there is no explicit rounding. What is happening is that the effect of the gravity on the velocity is calculated for a single tick (20 ms), and the effect is so small that the float number stays the same since it can't resolve that small of a difference
10:02

@Evelyn I don't understand this question

If you set gravity to, for example, 0.001, gravity will be set to (int)(0.001 * 100) = (int)(0.1) = 0

Wait, I'm going to tell you what I want to do.
13:34
A wonderful man risu made a script in python, which allows you to output the necessary commands in tune to slow down / speed up the game, everything works great, but there is one drawback. At a deceleration of 4x or more , when reaching the peak height during a normal jump, the player stops falling for 0.5 seconds or more with each deceleration
13:35
I want to fix it, I think it has to do with gravity rounding
Avatar
Assa 2024-11-14 13:36
is this a script which applies new tuning values every tick?
Avatar
Evelyn 2024-11-14 13:36
speedtune.py
1.04 KB
13:37
the way you use the tool is you run python speedtune.py <speed factor> [prefix] so for example python speedtune.py 0.5 tune would give you the commands for global tunes to set the speed to 0.5x

Either way, just this doesn't explain the player velocity sometimes getting dropped to zero while the internal velocity is still nonzero
13:39
Because the problem we're experiencing, for example at the apex of jumps, has the player stop close to the apex as the velocity gets close to zero, but then they start moving again as gravity is applied
13:41
the very slow up and down movement at the apex of the jump gets reduced to the player stopping slightly below the apex for the time it would've taken them to reach the apex and fall back down again

imagine the gravity setting having "steps", and with 0.5 you just have 12 steps

i am currently testing with 0.282 with 4 steps, it's still noticable
14:00
with 5 steps it's kinda okay, python speedtune.py 0.316 tune
14:01
I wouldn't go under it, the physics just miss the precision and then there are weird bugs with even smaller values

additionally the playercore, which contains positions and velocities, is also send over the network. There is also some rounding happening: https://github.com/ddnet/ddnet/blob/4f53dd8048edd72967ddcde90c5e002995f918e4/src/game/gamecore.cpp#L602 Then there is what deen said, that you add such a small floating point number to the velocity, that it mostly doesn't change (edited)

Anyone else having problems like this on fng? Dont know where to post this topic. Is this normal? There are a lot more micro lag spikes that aren’t visible at this resolution and frame rate, and many key inputs aren’t registering, which you also can’t see in the video. The actual experience is far worse, with about 1-2 lags per second. This issue seems particularly intense on FNG servers (probably because prediction margin helps in DDNet). Could anyone help me troubleshoot this? Is it possibly related to the client, or could it be due to the network path to the server?

Currently there is no good way to apply these tunes to your map except putting them in manually.
you can so easily add them to a map with twmap:
  • twmap edit konvert map into directory structure
  • add your tunings to the mapsettings JSON file
  • convert map back I already did something like that for more complicated physics
