Teeworlds - bridge

Can someone explain this to me? https://github.com/heinrich5991/libtw2/blob/master/doc/map.md#info Are the optional properties fixed size? How do I know which prop got included?

The author, version etc. properties are each an int that is the index of the data item containing the string, or -1 if the value is unset. The length of these strings is only really limited in the editor to the lengths defined in the linked doc.

opt is the prefix for optional indices. They are either a normal index or -1, marking it as unused.

Oh!

In valid maps at least. Invalid maps could also contains invalid indices like -3 or too large data indices

Interesting, would one want to parse those cases or just disregard the whole thing?

It's much easier to discard the entire map when you find an error instead of trying to continue in your tool with whatever broken state the map is in

Makes sense, thank you!

1:22PM

Who thought it's a good idea to make sub types dependent on the parent's type property? ;;

Are you building a map parser?

1:23PM

Are you aware of patigas twmap library?

I am, I'd just like a fully native typescript implementation of everything documented in libtw2

You can also ask patiga if he can get you ts bindings he did the same for python

1:24PM

His project his pretty dope and well matured

1:25PM

But not sure if he will do it or how much pain it is. If he won’t do it I guess it’s nice that you cover ts land

1:25PM

Oh you aim for native too

1:25PM

Ye then don’t mind my comment :D

Oh, I saw his work. He helped me a lot in the past with similar stuff already. I'm just not sure what I want to do with this in the future. All I know for now is that I want to make a minimal server implementation

1:26PM

So I have to parse the map file at some point

Do you also know swarfeys work?

1:26PM

He did networking stuff in ts

I don't think I do? Do you have a link?

GitLab swarfey

1:27PM

gitlab.com/swarfey

Oh, yes, I've seen it before!

1:28PM

But its only the client

https://gitlab.com/swarfey/teeworlds-client

Again, looking to implement the server. I believe it'll be much more useful than the client

Yes I think his server stuff never got finished or started

1:28PM

But net code is shared a lot

1:29PM

Well depends both are cool Server and client

1:29PM

But there for sure is a niche for server rewrites

I don't disagree that both are cool, but the flexibility of servers would make more sense imo

The only actually useful one I know is the one in C#

https://github.com/Matodor/TeeSharp

1:29PM

This one?

Yes

1:30PM

It’s pretty epic

1:30PM

I saw it in game he did a full on city mod in it

Yeah, it's a cool project. Unfortunately my C/++

1:30PM

# isn't great

1:30PM

I mean, city mods aren't really special imo

Are you planning to go open source?

1:32PM

Show me any other server rewrite that can even be actually played on mod or not

1:33PM

Also it’s a cool city mod. And it dependens on what you put in the city mod

That's fair. I guess I've never been a big city player.

1:33PM

I do plan to go open source at some point, when it's functional

If your project has a public repo share it I’ll be your first fan and Follower

Haha, thanks! I haven't made a repo yet tho. Like I said, I want to have something work first

1:43PM

Silly question tho. Are datafiles only used in maps? Kind of like a container?

1:44PM

I assume so, right?

yeah, I assume it was made as a generic container format but in the end on maps use the datafile format

2:06PM

only*

One thing I also don't quite understand is why in the version header, the magic key can be inverse of what it should be

2:10PM

ie. ATAD instead of DATA

https://github.com/heinrich5991/libtw2/blob/master/doc/datafile.md

2:46PM

NOTE: Readers of Teeworlds datafiles should be able to read datafiles which start with a reversed magic too, that is 'A', 'T', 'A', 'D'. A bug in the reference implementation caused big-endian machines to save the reversed magic bytes.

I get that, I just don't understand why they would just go with it instead of fixing it

It's so existing maps that were written incorrect can still be read

oof

@Blade in heinrich5991's entire map collection I think there were less than 3 maps with that bug, maybe it was zero maps in total

Yeaah, so I won't worry about it

Silly question but can you even see map info? Like, is there a way to see it?

And while I'm at it, does this look right to you guys?

"type_id__id": {
    "type_id": 15,
    "id": 0
},
"size": 4194304,

Blade

Silly question but can you even see map info? Like, is there a way to see it?

You can only see the map info in the editor (file menu > map details)

I must have missed that

4:19PM

Nope, it's not there for me

try save as -> map details

Ah, yes, it was moved in DDNet client

brainased robsti

In Teeworlds client it's in the save dialog

ddnet maximalist

Seems to always be empty for me, on all the maps I test. Which admittedly weren't many

yeah, probably not used very much if it's not shown anywhere in the client

Mhh, oh well
