would be nice to automatically dilate skins before uploading to skin database, or have some sort of mass-dilate functionality in the web editor

[ddnet/ddnet] Issue opened: #8617 Editor: the tile picker selection is buggy

Selecting tiles feels random. Sometimes the selection is working as expected. Sometimes it picks a smaller area. Sometimes it picks different tiles. Tested on debian 12, gnome, X11, windowed https://github.com/user-attachments/assets/767265fc-4cf6-4cf1-a3ef-516dd610490b

When will people learn? 1. Stop putting mission critical systems on Windows, it's not the reliable OS it once was since MS has cut off most of its QA 2. AV solutions are unnecessary if you properly harden your system, AV was needed pre-Vista because Windows was literally running everything as Administrator. AV was never a necessity on UNIX, whatever MS bundles in is usually enough 3. Do not install third party software that runs in kernel mode. This is just a recipe for disaster, no matter how much auditing is done beforehand by the OEM. Linux has taught multiple times that drivers should be developed and included with the OS. Shipping random binaries that rely on a stable ABI may work for printers, not for mission critical software.

@Ryozuki my BIOS bullied me so hard god damn - my RAM arrived and i installed it, left DRAM mhz on "AUTO" and my NixOS wouldnt boot up - after googling around for hours, thinking it's actually an issue with my NixOS install because windows would boot up automatically, i realized "auto" didnt set it to 6000, but 5700. it's odd that nixOS didnt wanna boot up tho, updating BIOS + setting it to 6000 manually is now fully functional with AMD Expo™️

[ddnet/ddnet] Issue opened: #8620 Switching active network connection on Android causes connection problems

Enabling WiFi while already connected to a server over mobile network causes the client to get connection problems but not directly time out. Seems like some packets still go through so sometimes inputs work and snapshots arrive. Not sure if we can do something about this. For now Android users should either disable WiFi or mobile network so only the other one is used consistently to get a stable server connection.

yo i was making my own demos using the snap builder and stuff and im a little confused. problem is: grenades are not interpolated my code goes like this

CProjectileData ProjData = ((CProjectile *)pEnt)->GetData();
// NOTE: do pEnt % 0xffff because the id will always be -1 somehow which doesn't work.
CNetObj_DDNetProjectile *pNetProj = SnapNewItem<CNetObj_DDNetProjectile>((uint64_t)pEnt % 0xffff);
if(pNetProj)
{
    int Flags = 0;
    if(ProjData.m_Bouncing & 1)
    {
        Flags |= PROJECTILEFLAG_BOUNCE_HORIZONTAL;
    }
    if(ProjData.m_Bouncing & 2)
    {
        Flags |= PROJECTILEFLAG_BOUNCE_VERTICAL;
    }
    if(ProjData.m_Explosive)
    {
        Flags |= PROJECTILEFLAG_EXPLOSIVE;
    }
    if(ProjData.m_Freeze)
    {
        Flags |= PROJECTILEFLAG_FREEZE;
    }
    Flags |= PROJECTILEFLAG_NORMALIZE_VEL;
    pNetProj->m_VelX = round_to_int(ProjData.m_StartVel.x * 1e6f);
    pNetProj->m_VelY = round_to_int(ProjData.m_StartVel.y * 1e6f);
    pNetProj->m_X = round_to_int(ProjData.m_StartPos.x * 100.0f);
    pNetProj->m_Y = round_to_int(ProjData.m_StartPos.y * 100.0f);
    pNetProj->m_Type = ProjData.m_Type;
    pNetProj->m_StartTick = ProjData.m_StartTick;
    pNetProj->m_Owner = ProjData.m_Owner;
    pNetProj->m_Flags = Flags;
    pNetProj->m_SwitchNumber = ProjData.m_SwitchNumber;
    pNetProj->m_TuneZone = ProjData.m_TuneZone;
}

13:23

i basically copied this 1:1 from the server code over at https://github.com/ddnet/ddnet/blob/75d2b82ccd4c97ddc72af51563aabb84a87aaa34/src/game/server/entities/projectile.cpp#L332-L340 (edited)

13:25

where did the embed go? huh

what is there to interpolate if the position never changes?

I removed the embed because it was only taking space

oki

why did you cast the pEnt pointer to a 64 bit integer?

Jupstar ✪

what is there to interpolate if the position never changes?

well projectiles positions are calculated on the fly as i remember. for grenade it should be CalcPos

heinrich5991

why did you cast the pEnt pointer to a 64 bit integer?

the clientside prediction somehow always returns -1 upon calling GetId() and the snapshot builder doesn't accept that (edited)

ah yeah, i remember that was the case for grenades

i have no idea why tho

13:31

    void *SnapNewItem(int Type, int Id, int Size)
    {
        dbg_assert(Id >= -1 && Id <= 0xffff, "incorrect id");
        return Id < 0 ? 0 : m_SnapshotBuilder.NewItem(Type, Id, Size);
    }

    template<typename T>
    T *SnapNewItem(int Id)
    {
        return static_cast<T *>(SnapNewItem(T::ms_MsgId, Id, sizeof(T)));
    }

these are the snap thingies functions. (also copied straight out of the serverside code)

but now you're generating random IDs based on memory addresses. that sounds wrong. are they consistent from tick to tick?

heinrich5991

but now you're generating random IDs based on memory addresses. that sounds wrong. are they consistent from tick to tick?

the addresses of the entities should stay the same

heinrich5991

but now you're generating random IDs based on memory addresses. that sounds wrong. are they consistent from tick to tick?

also they can't be conflicting. im not sure how i would handle the sound snaps if GetId actually worked since they need a id too

13:37

although they could just be random

13:37

logs of GetId

29.9 KB

13:40

ah ik why they are not set

13:42

new entities that are created within the prediction don't get ids assigned it seems

13:42

they only get set in the NetObjAdd func

13:46

although i don't think the ids have to do with the interpolation do they?

just debug the client where the grenades are rendered

13:47

best: only do a single grenade projectile

i think im missing some kind of snap info. s_LastGameTickTime seems to be the same thing every time

i had to add an empty CNetObj_GameInfo to the snap for the rendering to work

15:37

because it checks if the GameInfo exists and only then sets the LastGameTickTime

it works now.

After Vanguard, it's a matter of question of "whether one fuck up so bad, that they leak everything themselves" than "whether hackers leak from them"
