how do you change assets? theres a weird map with really dark shit

00:51

cant see anything

you can try playing in entities

00:54

cl_overlay_entities 100

and theres 2 choices, comfort and default, but clicking on either does nothing

01:00

oh that's so nice, thanks heinrich5991

does ddnet have fra srv hosted at ovh?

I know, I just need to keep an eye out while reading it :P

@Learath2 have u ever tried this https://dart.dev/

Dart programming language

Dart is a client-optimized language for fast apps on any platform

11:32

does this uses the java vm?

11:32

is this an alternative to java and kotlin

11:32

i wonder

I think its googles flavour of react native

11:33

Tho I didnt look into it much

apparently it compiles to machine code or js

Fully? Smells like it either doesnt support ios or it only compiles some parts to native code

11:36

any

11:36

i love how they make the web so fancy

11:36

but the language is probs boring

11:36

the power of marketing

11:38

@Learath2 yes u can use it for ios

11:38

dart is used mostly for flutter

11:38

and flutter can be used on ios

Okay read a bit. It's very similar to react native but has much more compiled ahead of time

11:40

Oh apparently even without flutter you can target native. It looks so nice

React Native provides native look-and-feel, while Flutter uses empty canvas and renders everything at its own, so it looks the same everywhere

11:50

i think that native look-and-feel is better, but who knows (edited)

Hm, I like the native look too. I'll take a look at dart too anyway. I already am fluent with react native anyway

who maintains the fng servers? @noby?

16:38

fng russia, etc.

16:40

it seems to generate a wrong server info field for the map CRC

16:40

I get stuff like .0.*./)\'-* or //\'/0(0,00 when it should be an integer represented as an ASCII string

16:41

b"226\x000.6.3\x00fng small\x00fng_snow\x00.0.*./)\'-*\x00438902\x0 0fng2+\x000\x000\x0032\x000\x0032\x00\x00"

16:42

between the fng_snow (map name) and the 438902 (map size)

yes

seems like the discord answer things seem to get used more often nowerdays. having a hard time to follow :/ @heinrich5991 there is a bridge that supports them btw

16:57

but i assume ur not interested in chaning the bridge

lol why it's top6 now?

so broken feature omg

still Global and Ger in /rank !:_:

ChillerDragon: not really. what is the other bridge?

can I do an EMP with arduino?

19:11

I have no knowledge about arduino and microcontrollers

19:11

just wanted to know

19:16

I am trying to make a tune zone cfg that ignores user input for movement (no jumps, no ground control, no air control). This was easy to figure out, and the left/right/jump are now locked out. However, I noticed that when moving around with only hook, if I hold down one of the locked out controls then the physics completely changes (like if I hold down left, it seems that there is no longer any ground friction nor air friction)

19:17

Has anyone else experienced this? Is it a known bug? Is there a tune cfg that will lock out controls but allow friction to not get messed up?

@std no, you can't

19:19

@ChillerDragon what about using Discord in web browser? i use always and it works just fine

:(

19:19

the arduino self destroys?

it's used for something else

lo

19:20

understood

19:21

anyways, you know where I can modift teeworlds/ddnet client to make my own? (edited)

19:21

just got into c++ and wanted to see if I can understand/change any code and make my "own" client (edited)

19:21

I was a c# peasant* (edited)

try to compile the source code first

19:23

then you can start doing some changes in there

okay

19:23

is it the teeworlds or ddnet client?

19:23

which one

ddnet

ok

19:23

thanks

So I guess to simplify my question, does ground friction and air friction temporarily get set to zero when you try to move left or right? If so, that means the tune zones can be kinda broken if trying to remove player movement ability

Here is a simple tune cfg that shows my point:

19:41

tune_zone 2 ground_jump_impulse 0
tune_zone 2 air_jump_impulse 0
tune_zone 2 ground_friction 0.5
tune_zone 2 air_friction 0.95
tune_zone 2 ground_control_speed 0
tune_zone 2 ground_control_accel 0
tune_zone 2 air_control_speed 0
tune_zone 2 air_control_accel 0

(edited)

19:44

When you get into that tune, you can't move and you can't jump. You can only move yourself by hooking things. That's good. But if you hold down a movement key (like left) while moving by hooking, then it seems to set air_friction and ground_friction to zero (which is actually 1 in this case) and your tee just floats around or glides on the ground without stopping until you release your movement key. This leads me to believe that friction is temporarily ignored when a player tries to move, so there is really no way to make a tune that simulates the player's A/W(space)/D keys not working. Is this correct?

yes, friction is only applied while not pressing a/d

Ah, yeah I just found it in the source code:

    // add the speed modification according to players wanted direction
    if(m_Direction < 0)
        m_Vel.x = SaturatedAdd(-MaxSpeed, MaxSpeed, m_Vel.x, -Accel);
    if(m_Direction > 0)
        m_Vel.x = SaturatedAdd(-MaxSpeed, MaxSpeed, m_Vel.x, Accel);
    if(m_Direction == 0)
        m_Vel.x *= Friction;

19:56

I would call it a bug, some would call it a feature. Either way now I can't make the map I was planning to make lol

19:57

I suppose your velocity would continually degrade if you applied it while moving, which is not the wanted behavior, ik

oh true, didn't think about that

At first it sounded pretty easy to lock out the player's movement keys with a tune, but apparently it is impossible. One (myself) could easily add logic to check if MaxSpeed and Accel were both set to 0, then apply friction under that condition:

    // add the speed modification according to players wanted direction
    if(m_Direction < 0)
    {
        if(MaxSpeed == 0 && Accel == 0) //handle tune to stop movement effects
            m_Vel.x *= Friction;
        else
            m_Vel.x = SaturatedAdd(-MaxSpeed, MaxSpeed, m_Vel.x, -Accel);
    }
    if(m_Direction > 0)
    {
        if(MaxSpeed == 0 && Accel == 0) //handle tune to stop movement effects
            m_Vel.x *= Friction;
        else
            m_Vel.x = SaturatedAdd(-MaxSpeed, MaxSpeed, m_Vel.x, Accel);
    }
    if(m_Direction == 0)
        m_Vel.x *= Friction;

This would allow me to make my map, but I don't imagine anyone else would vote for this change

20:12

Changing the basic TW physics just to make a map work is silly. Now I suppose your wondering about my super cool map idea. The map is called "Single-Handed" and the theme is that some parts lock out all your mouse controls so you only have movement (left hand), and other parts lock out all your movement controls so you only have hook and weapons (right hand). Certain parts have one left handed tee and one right handed tee, while some parts would have only left handed tees (only being able to bump each other to gain any extra speed or height, etc). There are lots of cool mechanics that could be mapped using this idea.

20:14

Imagine a semi-complex gores part where your movement keys don't work, and you can only hook. Makes it very difficult. Imagine you can't move, but you can hook your partner who can move, and that's the only way you can move in that part. How neat would that be? xD

Since the original teeworlds did not have tuning of movement power, this was never an issue. But I don't think friction should be ignored while a player tries to move when they have no movement power. It's a bug :P

What are peoples thoughts on adding a caching layer for the SQL database?

what should the caching layer do?

The response times are starting to be impacted as the records per maps increase. Most of the queries are relatively static top5 will likely remain the same whether player X or player Y calls it. No need to fetch it twice.

22:35

I suppose it comes down to the current load on the database. If it is still a low threshold then the latency delay isn't much of an issue.

The database already does that

22:50

and on our production db we have lots of indexes to improve performance

22:50

db server cpu usage is quite low: https://ddnet.tw/stats/server/#db.ddnet.tw (2 CPU cores, usually at 1-2% usage)

22:51

If you add another caching layer, how will you know when the data is out of date? This is tradionally the job of a database
