menu concept alpha theres a LOT that needs to be done but this but i do believe that a proper automapper GUI would have a menu sort of like this a list of tiles, and when you click one of them, you can edit its properties you can add new tiles, rearrange them by dragging them, add new runs, showed by a large break, and possibly a name (which is a comment in the automapper code)

Is there any documentation on the DDNet master registration process?

I want to create a fast porting implementation that works with some old mods

there is some info here https://codedoc.ddnet.org/

Thanks

looking at all the specific index rules for ddnet_grass.png, it's easier to see how this works!

Here something to keep in mind:

some tiles are connected and have other rules, like the big skeleton in grass main
randomness: often you have a basetile and then some detail doodads in them, like bones in the walls or gold in desert main
There are some tiles where your 3x3 rules don't apply and you'll find places where you need 5x5 relationships
tilesets are often not complete, how to handle cases where tiles are missing

Good luck with your project!

[ddnet/ddnet] Issue opened: #9666 Persistent client data can be loaded by other players

There seems to be a bug in the persistent client data. Where data stored about one player can be loaded by another. Reported by @M0REKZ in ddnet-insta.

Found a consistent way to reproduce the bug: * Open 2 DDNet clients * Join first client * Join second * Join first client dummy * Join second client dummy * Make FIRST client dummy spectator * Change map * Join S...

Is there any more documentation? (edited)

do we have a sign function in the engine, just returning -1 or 1?

Assa

do we have a sign function in the engine, just returning -1 or 1?

There's one in teeworlds (edited)

can't find it in math.h, searched for sign and signum

I didn't find it in DDNet code, either.

also searched for sgn and sng, I guess this is deliberately not in in order to handle the 0 case properly

09:42

or I am searching for the wrong thing

Don't think we have one. I can't imagine where we might have used one

Assa

Teeworlds had one, but it's gone on DDNet. What do you need it for?

I am currently working on different versions of new speedtiles, my latest idea uses the dot product and the sign of the dot product determines the direction of the projection of a vector. A projection from one vector to another can either point in the same or the opposite direction. In this case the length of the vector is equal to it's speed, so I need the sign of the dot product in order to know if the speed is added or subtracted (edited)

10:24

If we don't have one, then simply int Sign = DotProduct < 0 ? -1 : 0;, I am just trying to program against ddnet standards and using it's stl, I just thought I may have missed it (edited)

10:27

Why? The max speed in the old implementation just limits the speed in the speedtile direction (and not orthogonal to it)

is there no std version

10:35

I am just trying to program against ddnet standards and using it's stl

I think ddnet relaxed this, bcs why would you not use the std version xd

occording to this, no (edited)

cpp/numeric/math/signbit

this is deliberately not in in order to handle the 0 case properly

hmm

10:38

For this this doesn't matter tho, because the lenght of the projection is 0, if the dot product is 0

10:40

guess I'll use signbit, thank you!

[ddnet/ddnet] Pull request opened: #9667 Make sv_port read only

The same could probably be done for econ configs and bindaddr. But I am not 100% confident about them. But changing sv_port and it never having an effect is confusing and it also should never have an effect. Having a reload read that in would be horrible ux for connected players.

I think this is possible if you modify a proxy and force a reconnect. Maybe with an econ client detecting that this vote passed which in turn modified the proxy, while this would work this would be a totally bodged solution

Thats true, but you can easily coordinate an attack with this type of "redirection"

12:40

just 63p players join a server and get redirect the same time, because this would be legit

yeah, thats a problem. i cant force client to send packets directly to host i want redirect to, so, proxy servers are pretty useless in world of teeworlds

server should confirm accepting of these clients then

there's nice tedtalk about nocc, but its fully in russian

zhn

too complex

Avolicious

too complex

if server-server communication is complex, id suggest server X sending to master a list (whitelist or blacklist) of servers that can or can not redirect to server X so client would distinguish if its good redirect or not

13:08

imagine server redirecting to localhost:8303 xdd

even more complex

i don't see any complexity

maintaining an allowlist/blocklist?

Avolicious

maintaining an allowlist/blocklist?

server owner would maintain it

13:08

like list all your servers and thats it

how can the receiving server make sure that the player is really connected to the origin server?

zhn

server owner would maintain it

doesnt scale well

13:09

atleast for server networks that are scaling up/down as needed

Avolicious

how can the receiving server make sure that the player is really connected to the origin server?

is therr any reason to make sure it is? if not it would be just a regular connection, no?

Avolicious

atleast for server networks that are scaling up/down as needed

but you maintain community list somehow?

zhn

is therr any reason to make sure it is? if not it would be just a regular connection, no?

it should always be just a regular connection to not avoid password checks and so on

Avolicious

it should always be just a regular connection to not avoid password checks and so on

ofc, that's why i don't see any problem
