That's rarely the issue, given how they're pretty much the same

Nice! good job

having animated flags in vanilla would be great

Hey, can you please make the scrollbar in the demo section less sensitive. I have auto record on, I have around 10 demos per day or more. I scroll once and it literally skips a month of demos. I even counted it and it skipped around 322 demos. and 10 * 30 = 300, so yea it skips a month.

13:46

I find it very annoying..

may i? https://youtu.be/3_H7BFsyupI (edited)

@darkstar i feel like you can use arrow keys to skip 5s of demo

@darkstar if you mean the file browser, it is fixed in master branch already. so it will be less sensitive in the next version

yes I mean the 'file browser', so it will be fixed in the next version ok thanks

np

what is f in the client ?

18:54

// reset velocity so the client doesn't predict stuff
        m_Core.m_Vel = vec2(0.f, 0.f);

(edited)

18:55

like this

18:55

for the ninja

18:55

is that the friction in air ?

18:55

help pls

@Deleted User it's the same as 0.0 here

19:04

0.0 is of type double, 0.0f is of type float

what is double ._.

variable type

double is an 8 byte float type, float is a 4 byte float type

19:09

like int is 4 bytes and short is 2 bytes

ok

19:15

2.03 KB

19:15

can someone say if the code is good and no erorr are in ?

19:16

please ?

try to compile, if you would get errors - you will know it

ok

19:22

it works, but i don't what i wanted to do

19:22

the programm doesn't create more than 3 bullets

19:22

and i requested to create 12 bullets

19:23

so what tha heckkk

19:29

can someone help me pls ;-;

19:30

idk how to fix it

Any tips why this code even can segfault?

CEntity *CGameWorld::FindFirst(int Type)
{
// i am checking that array exist, so it should be initialized or at least contain nullptr's
    if (!m_apFirstEntityTypes)
        return 0;
// segfaults here, how this is possible?
    if (!m_apFirstEntityTypes[Type])
        return 0;
    return Type < 0 || Type >= NUM_ENTTYPES ? 0 : m_apFirstEntityTypes[Type];
}

cpp

20:10

I feel so noob.

20:11

I know there are linked lists and have more or less read the code already for removal, initialisation and destroy. But it seems that in worst case m_apFirstEntityTypes[Type] should always be accessible and contain nullptr or 0

c++
CEntity *CGameWorld::FindFirst(int Type)
{
     if(Type < 0 || Type >= NUM_ENTTYPES)
             return 0;
     return m_apFirstEntityTypes[Type];
}

(edited)

20:13

if Type is < 0 or >= num, then you cant access the array

Ok, nice point. But I have crashdump where Type is 5 which is a valid entity type in my mod (a custom entity). (edited)

20:14

NUM_ENTTYPES is 25 in my mod.

dont do these weird extra checks

20:14

no need

20:14

it just is not what you want there

Then it will just segfault on last line. I've added it for a debug

Then the error is not here but somewhere where you use the entitiy returned from this function

it cannot do m_apFirstEntityTypes[5] for some reason

if the function returns 0 you cant just use the entity

but it's the top of a stack on crashdump

u need to check after the function is used

Yeah, but stacktrace is not where I use returned value but where I am accessing it.

20:16

Can stacktrace in a crashdump be wrong and point to some earlier point?

c++
CEntity *pEnt = GameWorld()->FindFirst(ENTTYPE_XY);
if (pEnt)
{
       // do something with it here in safety
}

But... why segfaults points to inside of FindFirst and not in the code in brackets then?

20:18

Is that possible?

20:18

Maybe this is how gdb works?

You can have undefined behaviour

20:18

good night

    for (CEngineerWall* pWall = (CEngineerWall*)GameWorld()->FindFirst(CGameWorld::ENTTYPE_ENGINEER_WALL); pWall; pWall = (CEngineerWall*)pWall->TypeNext())
    {
        if (pWall->m_Owner != m_pPlayer->GetCID()) continue;
        GameServer()->m_World.DestroyEntity(pWall);
    }

this is the previous frame

20:18

gn, thanks

thonk

it is possible you have some sort of optimization enabled?

I think it's possible, it's a release build with debug symbols

that would make sense

20:19

optimized binary can jump all over the places

1

It seems that you both helped me a lot.

20:20

I was just stuck with this, error seemed to be pointing to the wrong place.

20:20

Now I know that it is possible.

20:20

Thanks! (edited)

When in doubt get a debug build

can someone help me to create a programm that check the team we are and the other tees

21:49

idk how to start

21:50

(sry for bad english btw)

I'd give you a hand but I don't seem to understand what you want to do

I want to create a program that checks which team I'm on and checks the players if they are on the same team as me

21:52

same for enemmies

21:54

so ?

21:54

@Learath2 and i want to create it in .lua file

Well there is no lua virtual machine inside teeworlds, so you can't code in lua

but i create it for the client not for the server

21:56

i think its an another kind of code ?

Both the server and the client are coded in C++

22:00

I think there is ATH that has lua scripting in it, but that's 0.6 only

oh yes i want to code it for ath in O.6

22:03

so how to code it ?

22:06

@Learath2 sorry for mention but not answering :/

Sorry, I'm not familiar with ATH's lua hooks

22:08

It's fine, you can always ping me when I'm being slow. Means I'm working on something else and if you don't ping you'll never get your answer

ah ...

22:09

ok thanks :D

22:09

but.... do you know someone who know how to code in ath lua script ?

22:10

@Learath2
