m_VictimRenderInfo is probably an array or a pointer? e.g. if it's an array, you need to index it first, like m_VictimRenderInfo[1].m_CustomColoredSkin

I thought I did index. Or, am I also doing that wrong? Basically I have an outside buffer to store each tee skin that will be packaged inside the kill message.

c++
CKillMsg Kill;

...

  Kill.m_VictimID = pMsg->m_Victim;
    if(Kill.m_VictimID >= 0 && Kill.m_VictimID < MAX_CLIENTS)
    {
        Kill.m_VictimTeam = m_pClient->m_aClients[Kill.m_VictimID].m_Team;
        Kill.m_VictimDDTeam = m_pClient->m_Teams.Team(Kill.m_VictimID);
        str_copy(Kill.m_aVictimName, m_pClient->m_aClients[Kill.m_VictimID].m_aName);
        if(m_Sendable = 0)
            {
                m_aVictimSkinBuffer[m_VictimSkinCurrent + 1] = m_pClient->m_aClients[Kill.m_VictimID].m_RenderInfo;
                m_VictimSkinCurrent = (m_VictimSkinCurrent + 1) % (MAX_KILLMSGTEAM - 1);
            }
        else
            m_aVictimSkinBuffer[0] = m_pClient->m_aClients[Kill.m_VictimID].m_RenderInfo;
    }

m_Sendable is another packet, which determines the actions of each packet delivery. If m_Sendable is 0, it's in a write state that only fills in all the buffers. If m_Sendable is 1, then it's in a read state, which makes sure the first item in the buffer is the person who died / gets strong. It will package the buffer, alongside the size of the team, or the maximum allowed in the killfeed buffer.

04:00

Wait, did I not- NO I FORGOT TO IMPLIMENT THE BUFFER

do you still get a compiler error?

04:04

if so, it would be nice if you could also copy-paste that

I want to fix this buffer first, then test to see if that was the problem.

04:04

There was meant to be a buffer outside of CKillMsg Kill, but currently it's writing to nothing.

I don't understand what buffer means in this context

In the CKillMessages class, outside of struct CKillMsg, I made another global array to store tee skins for each team member that died.

c++
CKillMsg m_aKillmsgs[MAX_KILLMSGS];
int m_KillmsgCurrent;

CTeeRenderInfo m_aVictimSkinBuffer[MAX_KILLMSGTEAM];
int m_VictimSkinCurrent;

heinrich5991

Yeah, there's still an error.

c++
int KillerSkinsValid = 0;
for(int i = 0; i <= Kill.m_TeamSize; i++)
            {
                Kill.m_VictimRenderInfo[i] = m_aVictimSkinBuffer[i];
                if(!m_aVictimSkinBuffer[i].m_CustomColoredSkin && m_aVictimSkinBuffer[i].m_OriginalRenderSkin.m_Body.IsValid())
                    KillerSkinsValid++;
            }
            bool KillMsgValid = (Kill.m_VictimRenderInfo.m_CustomColoredSkin && Kill.m_VictimRenderInfo.m_ColorableRenderSkin.m_Body.IsValid()) || (KillerSkinsValid == Kill.m_TeamSize);

(edited)

Kill.m_VictimRenderInfo[i]

04:11

Kill.m_VictimRenderInfo.m_CustomColoredSkin

04:11

one of these is wrong

04:11

either m_VictimRenderInfo is an array or it is not

Oh my god. I thought that was Kill.m_KillerRenderInfo, which doesn't have an array. (edited)

04:12

Oh my god

04:12

I'm blind

04:15

It compiles

\o/

Now that I have the backbone done, I just need to do the actual debugging of the packet sending, which won't be too hard.

Why if(m_Sendable = 0)?
I think it need be if(m_Senable == 0) or if(!m_Senable)

Why if(m_Sendable = 0)?
I think it need be if(m_Senable == 0) or if(!m_Senable)

I already changed that to if(!m_Sendable)

Oh, oke

Emitting Safer Rust with C2Rust

In this post, we will discuss recent results from Immunant and Galois in extending C2Rust to emit memory-safe Rust in certain cases. With this work we aim to shift a meaningful part of the translation burden from the human to the machine. Up until now, C2Rust has only been able to translate C to unsafe Rust that is no safer than the original inp...

imagine we add 128p support

[ddnet/ddnet] Pull request opened: #6428 Extend `CScrollRegion` to support scrolling when mouse at edge

Add ScrollRelative function to initiate relative scrolling programmatically, to realise scroll regions that scroll when the mouse is being dragged at the edge. Add DoEdgeScrolling to encapsulate all the necessary edge scrolling logic based on the position of the mouse. The edge scrolling starts at a fixed distance from the edges. The scrolling speed is dependent on the distance of the mouse from this border.

imagine you would start to use the servers you bought to the full capacity aka. 1024 players support

?XD

First step: Add comprehensive tests for all the physics Second step: Improve physics performance without changing any of the physics

sounds like a good plan robster

Q: "how to use grep?" A: "rewrite your own grep in rust because grep bad"

that guy probably also rolled his own crypto because openssl is bad even on his 700GB ram machine xd

oh boi i wrote a 100 line py script and then a 200 line bash script that releases it to pypi xd

there's no reason for it to hold matches, just count it

why would u be sad

yes

its openai logo

take the stonks job

i generally dont trust these ppl xd

yeah lul

they make it sound nice and then they find excuses

tell the headhunter you want 50% of what he gets from the company

18:40

then take the job and quit

18:40

ez money grab

also when they mention another language, specially JS, besides rust, you WILL most probably use little rust there

18:40

my life power comes from using rust

master servers slow

yea they slow cuz rust

18:49

ryo come to munich our company empowers devs to use as much rust as they want

when i look at jobs in my region rip xD c#, delphi, java
