Today I learned about Intel’s AI sliders that filter online gaming ...

Due for release this year.

pretty cool

00:24

this screams latency though

Knuckles cracked n-word cranked up to 11 yup. its gaming time

what were they thinking

[ddnet-maps:master] 1 new commit

e9a2adc A Best of Three, M First Try, M pedeuliar - ddnet-maps

i have question if im on platform and i press d i will reach speed 10 in 5sec, then i continue running with d but i fall of platform do i : 1) keep my 10 speed 2) speed is set immediately to 5 3) speed decrease from 10 to 5 with rate of x (x = ?)

@devs pls add units in ctrl+shift+d

@devs pls add units in ctrl+shift+d

lets add feet and yards and stones, the american way

09:02

BASED

lets add pixels

no guys in sub-tiles/tick

09:22

bcs its the smallest units of the game

09:22

st/t

09:22

u cant get half a sub-tile or half a tick

would if (false) be stupid?

kek

Eeeeeeh, there must be a better way to do this

ikr

12:05

but i can't think of any on the spot rn

I can only think of uglier ones, maybe this is as good as it gets

i can just get rid of else and let it compare all the way through, but i don't really want to.

Uhm, wait why do you need this to be dynamic?

Learath2

Uhm, wait why do you need this to be dynamic?

idk. feel like it.

12:07

gamemodes.h for reference

Image attachment

12:07

oh, if you are wondering why I'm comparing. i'm making chat command /room 1 ctf

2 questions, First: Why do you need AddGameType when is this called? Second: Would you ever want to register the same gamecontroller with 2 different names?

AddGameType is for enabling gamemodes

12:09

like you put add_gametype dm;add_gametype ctf in config, then the rooms can only be dm or ctf, can't be anything else.

Ah okay

then 2 different name is for add_gametype 1v1dm dm sv_player_slots 2

12:10

then /room 1 1v1dm and /room 1 dm are both dm types but with different settings.

So how about you build an array of all valid gametypes using the preprocessor, then do one single check?

maybe scorelimits are different and stuff

Learath2

So how about you build an array of all valid gametypes using the preprocessor, then do one single check?

bravo, i'll try to do that rn.

12:12

but wait

12:12

i can't put constructors in array.

12:12

can i

Well the part of the code I see is just using TYPE, that's why I suggested that

yeah, i had this already

Image attachment

The usual solution is to have a factory function, though I guess that's starting to make it ugly

12:14

(since you can't take the pointer to a constructor)

right, i'm making this ugly rn, just so i can register more gamtypes with two lines in gamemodes.h

12:15

instead of poking into factories and stuff

I think this is fine btw, if(false) looks odd but I think it's much better than the alternatives

12:17

I wish C++ had first class classes

12:18

Would make stuff like this much prettier

12:20

@TsFreddie I have a solution for you that is not as pretty and will make all the CS people hate you but get rid of the if(false)

let's hear it

I even know a convoluted way to make it palatable to CS people (but they are insane so who cares)

12:21

Just use a goto

12:21

(or if you are scared of our theory overlords put it in a do { ... } while(false) and break out of it

12:21

)

do {} while(false) seems like it is in the same ballpark as if (false)

12:23

goto tho.. i don't know..

Which is why I suggested it in parenthesis, if I was doing it I'd either keep the if(false) or use the goto

12:23

I might use the goto just to annoy people

i'm more scared of goto than annoyed. cuz multiple people taught me to never use it lol

multiple people who've read just the title of one letter by djikstra

just thought more about goto.. i don't know how would it work tbh.

12:25

I can't take CLASS out with the goto i don't think

Well you'd just remove the else and goto a label after the #undef

12:27

As said, just keep the if(false) it doesn't look too bad anyway

yeah, i'll keep if (false)

Image attachment

12:29

i don't even know if this is legal

that looks completely insane

12:30

You just needed a single goto, not two

oh right. i don't know what i was thinking

12:32

justatest

there are some very cute goto patterns we can't use anymore because some people take things so damn literally, they really think things like do { ... } while(false); is better, but it only makes your code more cryptic

12:35

I've also seen for(int i = 0; i == 0; i ++)

nouis

12:36

is for(;;break) valid?

12:37

nope. tried it

https://github.com/Learath2/libpbo/blob/master/libpbo/pbo.c#L233 here is a pattern I use a lot

12:39

Though this is not the best example, I don't think I have any better ones public

12:40

Another perfectly valid use is breaking out of nested loops, some people will tell you to make these into one-off functions. To those people I say no

justatest

(fwiw these are only necessary because C just lacks the tools to do this in a clean manner)

12:42

C++ has exceptions and RAII that can handle the first usecase for you. Some languages have break <n>; pattern that will break out of n blocks

12:44

and if you want more examples of decent uses of goto and have a thing for "appeal to authority" arguments Knuth has a great paper on this

12:44

iirc called "Structured programming with go to statements"

i'd like a break <n> very much ngl

Yeah, I think rust had a proposal for one

Also I was genuinely hoping for(;;break) was a thing.

why?

idk, it looks funny

Learath2

Yeah, I think rust had a proposal for one

rust has them already since long https://doc.rust-lang.org/rust-by-example/flow_control/loop/nested.html

Nesting and labels - Rust By Example

Rust by Example (RBE) is a collection of runnable examples that illustrate various Rust concepts and standard libraries.

ah, this is also acceptable

13:52

I meant a proper arbitrary break though, like out of any block not just loops

and more readable than n blocks

13:53

@Learath2 how would this work outside of loops?

13:53

isnt that a goto

well a very limited goto that would just go to outside the block

oh

13:54

well atleast u can expect to maybe have this in rust i wonder how long it would take for the grandpas in the c++ standard to add this

13:54

monkalaugh

never lol

13:55

C and C++ are pretty static now that they have accepted to never break backwards compatibility

pvp scoreboard with teams looks pretty goofy

could it be a thing that you can filter maps by date in the editor when you try to load them ? and not only by name

what the difference between vec2 m_MousePos[NUM_DUMMIES] and vec2 m_TargetPos[NUM_DUMMIES] m_MousePos changes mouse position, but i dont see any m_TargetPos changes, even as another player

14:58

(client side)

mousepos is screenspace， targetpos is worldspace iirc

Apparently if you change from a non-team game to a team game while snapping gameinfo. There's a high chance that your character's color won't get updated to team color.

18:48

And..... apparently you can just resend map info to force client to refresh it's state. (For 0.6)

map info is treated as a map change

18:49

so the client re-enters the game

Ye, but it happens super fast if the server keeps snapping everything.

18:50

The connecting screen only flashes by for 1 or 2 frames on my MacBook. Haven't tested with high ping tho.

18:51

For 0.7 you just send team change message to spectators and back then it'll update.

18:51

18:53

And it sounds like a non-red/blue team game is possible for 0.7 kek

What do you mean by that?

TsFreddie

would if (false) be stupid?

how about switch case construction with a default at the end?

Similar to demos browser. Could even make it sortable if you want to go fancy. Anyone interested in implementing?

yes me

it u

seems chromes developer tools are still better after all this time :/

how long has n9mkoik had rank 1 in rankpoints

there are still some weird things with both browsers concerning css

23:37

on chrome, scrollbar props are still prefixed and don't follow the conventions, and on firefox, form inputs are very ugly and often have different rules when it comes to changing their appearance
