i’m perma stuck at 277 points

02:29

i just did a map and didn’t gain any points

idk if it was fixed but my points are now added

yes sometimes it takes a bit for points to register

Can interact with other on solo server rn

14:04

Nobody is solo on that server wtf

Hacks

14:08

Hm doesn't work on other servers

gogogo r1

why u can collide with other player on solo server?

@Learath2 @deen

14:19

seems like sv_solo_server 1 isn't applied

maybe the server has an intel gpu

14:51

are the servers running with ubsan btw?

Ubsan slows them down, so no

14:53

@louis all solo maps or just that map?

well only a bit, and u dont need to run all with ubsan (edited)

idk @Learath2 just this server the map hasnt been changed so idk

Port and server pls

How to update ddnet in android happy

Other maps too @Learath2

@Learath2

15:15

check ddnet client

@Deleted User i wanted to run 1 server on GER2 with ubsan and one with asan to detect some more problems

15:26

@ZhakkoDyys we have removed android support from ddnet client, no updates available

1

15:27

I'll actually try the ubsan/asan now

@Deleted User ger2.ddnet.tw:8305 is now asan, ger2.ddnet.tw:8309 ubsan, even got the first report when I joined with some divisions by zero (edited)

we should deffs fix the one caused by targetx and targety

15:54

the problem is smth / 0.0 = inf and 0.0 * inf = nan

15:55

so normalizing should be carefully done

division by zero is well defined by the floating point standard tho, its really 0 * inf

15:56

but i'd prefer finite math tho

15:56

finite math is the most robust thing you can do

do you want to look into a fix or should I? (edited)

i can start with the NaNs i had in my pr

sure

thanks, fixed

the problem is smth / 0.0 = inf and 0.0 * inf = nan

This is how shotgun launch works though (two tees stand inside each other and one of them fires shotgun)

23:01

when the game tries to calculate the direction in which to accelerate the other tee, it gets NaN and when NaN gets casted into int (inside a function called quantize, I think) it gets a value of INT_MIN. This launches the tee up and left (although horizontal movement is dampened by ramp).

23:03

@Deleted User fyi ^

23:10

Idk if it this bug is necessary to complete any maps. It's necessary to get to a chill area in a gores-like map that starts with a big waterfall, but I can't remember the name.

i know
