the tune variable ground_control_speed is broken for small values, If you set it to 0.5 you can only move right on the ground, if you set it to 0.3 you can't move at all, I made a testmap

I'll open a github issue, too

How to fix please (edited)

I can Imagine this breaking physics If we Change that tho

I am sure there is some bug in the physics, you can only have multiples of certain speeds

11:45

but I agree, this would "break" the currently existing physics

11:46

There are also some bugs I wish to be fixed, like the bug where you don't get your jump back, because nobody gains any advantage with that (edited)

Ah the good old you Hit the Edge and dont get DJ, or the you dont Hit Edge But get DJ ? kek

the hit the edge and don't get DJ bug ^^ I already know how to fix it, because it's already fixed for jumppads

12:52

See here, it's already fixed for ElasticityY > 0. This bug occurs, because you don't hit the ground at a tick, but only in a subtick

ah so you hit it between two ticks and the game interpolates you to reset speed?

kinda

i've recently changed os to linux and can't play the game, tried fedora and endeavour on kde, installed game through steam, website and tried cactus client. Sometimes i can't even join servers and when i join and I'm able to play, game crashes after a bit usually after i go a certain distance on the map or zoom out. Any solutions?

It would be useful to know:

what renderer you use (settings -> graphics)
what hardware you have, CPU, graphics card
what linux distro exactly (like which version)

Can you try using x11?

I've tried it had the same issue, didn't make a difference

ok, you can try a different renderer. if that still crashes, i assume it's easier to debug using a debugger and compile ddnet from source (if you are confident with that, it's not very hard) (edited)

the game only gives you the jump back, if you're on the ground on a tick, this is also the reason for the other "bug" where you jump and get your jump back on an edge

select a different one in the client under settings -> graphics. Which one is currently selected?

and Vulkan does not work?

your GPU is old, but i think it should still support it

it show's me this when i try vulcan

seems to be working, at least it doesn't crash when i join a server. Can't say for sure as it usually happend on ger and ger3 kog servers which are down rn. Thanks for the help

just wondering: what does vulkaninfo | grep -A1 driverName in a terminal print for you?

ah it uses amdvlk

14:14

i dunno your linux distro, but if u find a mesa-radv package

14:14

better use that

14:16

apparently like this:

sudo pacman -S vulkan-radeon lib32-vulkan-radeon
sudo pacman -R amdvlk lib32-amdvlk

now the game lunches with vulkan, thanks

i was rendering demo , paused in that demo , choosed other guy , moved slider to start , resume again , after it got recordet , my screen in game froze , i was looking is video renderet ( it did it ) , i want back to game the game was stuck in one frame in demos folder , after some time it resumed and i got message rendered successfully . ( around 1 minute ) ( version 18.4) (edited)

so your game froze, but you were still in the game (tabbed in) when it froze?
after the freezing began, you tabbed out to see the video file?
back in the game it unfroze as soon as the video was rendered?

the game was froze , i tabbed out ( was last frame of video ) , i looked video in pc there was and it was renderet ( i could watch it ) . i enter back in game , there was demo folder and it was frozen . ( i wanted to write it ( in bugs ) , but for no reason it unfroze and i got message renderet successfully and background started moving again) . in that state i was not able to move mouse . (edited)

how long do you think was the freeze in total?

about minute you can see it dump file (edited)

ah yeah right
