This is Hacker Public Radio Episode 3,729 for Thursday the 17th of November 2022.
|
|
Today's show is entitled, Contributing to Super Tux-Cart.
|
|
It is hosted by Celeste and is about 15 minutes long.
|
|
It carries an explicit flag.
|
|
The summary is, Explaining the Warplow to Contribute to this FOSS game with Media Assets.
|
|
Okay.
|
|
Hello everyone.
|
|
This is a bit of an experiment of recording experiment.
|
|
As I usually tend to make way too long audio messages while I drive,
|
|
I put the phone in recording mode to a friend of mine,
|
|
and when I stop the car, I stop the recording and my friend does that too.
|
|
So, we exchange these long messages.
|
|
So I thought, hey, let's make a car rumbling podcast while I drive,
|
|
and I will stop the recording when I reach the destination.
|
|
So, about 15 minutes, I guess.
|
|
Right now, as a traffic light.
|
|
So, today's topic is about how to contribute to Super Tux-Cart.
|
|
A game which, from now on, I will call Super Tux-Cart,
|
|
because, you know, I'm Italian and saying the U-A is so strange.
|
|
It sounds so bad to me.
|
|
I will name the Penguin Tux, not DAX.
|
|
So, Super Tux-Cart.
|
|
For those who don't know it, it's a 3D racing game, mainly for Gnolidux,
|
|
under a free end-up in source license, and not only the engine is free end-up in source,
|
|
but also all the assets.
|
|
So, I think it's a great opportunity for those of you who are interested in 3D graphics or audio production,
|
|
or they are 2D artists, even, to join making some improvements to the game.
|
|
Obviously, you can also contribute to each programmer in C++.
|
|
But, you know, you expect that a software needs programmer,
|
|
but a video game also needs artists from every possible spectrum, every possible subject,
|
|
from graphics to 3D graphics to audio.
|
|
Animation to animation is a really difficult part for artists.
|
|
So, if you know that, or you're studying animation,
|
|
it's a great contribution you can give to the project.
|
|
So, about this stuff, I want to say that you will have to release your work under
|
|
a creative commos, share like, or similar, one of the creative commos licenses.
|
|
So, that first, the artwork can be incorporated into the main game, or in the Adon's website.
|
|
And secondly, you will probably, you're encouraged to share not only the end result,
|
|
but also the project files.
|
|
I'll try to explain it.
|
|
When you build some assets, being that audio, or a picture, you have two files.
|
|
One project file, for audio, it would be an art or maybe audacity project.
|
|
While for 2D drawing, it may be a CRETA project, or GIMP, Inkscape, or 3D Blender.
|
|
So, the original source file, so that others can make changes and adapt it.
|
|
On the other hand, you don't include the Blender file in the game.
|
|
You will include only an exported model in a specific format that the game wants.
|
|
Same for the textures, you won't include the CRETA file in the...
|
|
Sorry, a friend calling me with the old Nokia tune, and that's part of the show, I guess.
|
|
I will cut it.
|
|
Okay, the call is finished.
|
|
What I was saying, yes.
|
|
So, you don't include the CRETA project or Inkscape file into the main game.
|
|
You will include probably a PNG, probably scaled, because you won't include a 4K resolution PNG into the...
|
|
into...
|
|
into a small texture that it's used in a little part of the model.
|
|
It's a completely waste of resources, and it will slow the game, or it will make it
|
|
load so much stuff in the RAM that it won't run on lower devices.
|
|
So, you will have the source files at full resolution with the license that others can...
|
|
so that others can edit it and change it, and the production file.
|
|
So, to guide you, there are two repositories.
|
|
One for the code, it's called SDK code on GitHub, and one on the SVN.
|
|
Yeah, it uses SVN, which is called the media label, which only has every possible source file of the tracks, of the tracks, of the car, of the arenas.
|
|
Everything is there, and you want that.
|
|
Why don't you load the entire media label with the source file?
|
|
The answer is that, if you are creating a track,
|
|
you will be able to import or readymade props or readymade trees, benches, houses, maybe some skydome.
|
|
The skydome is a closed area, which represents the sky in video games.
|
|
I don't know how to keep a better idea. It's like a sphere, but seen from the inside, and it acts as a proxy of a sky.
|
|
So, I was saying, you don't include the real source file with the game.
|
|
You will include only the production file.
|
|
Which tools will you need to contribute in some way?
|
|
So, I was saying, one of the benefits about trying to contribute to the assets, maybe with a character.
|
|
You learn the workflow of a real game by doing so.
|
|
You learn that you will have to interact with the already existing style.
|
|
So, if you are an artist, you will be forced to match the style of the rest of the game.
|
|
So, it keeps, it maintains the consistency.
|
|
Also, you will be able to publish your and product, maybe your character with the card, or in the main game,
|
|
or if it's not possible in the main game, you will be able to publish it in the add-on website.
|
|
So, Secret X Cartamont takes these big add-ons website, where everyone cannot start, and it's directly integrated into the game.
|
|
So, from the main screen of the game, there is an add-on section.
|
|
And if you are connected to the internet, you can download what you want from that without the event opening a browser.
|
|
And it's very convenient that people will be able to find out your and even rate your product, your creation.
|
|
So, this is also useful if you are starting as a curriculum as a portfolio of your work to show to an employee or an employer
|
|
to showcase, hey, I can do this, I can do 3D model, I can animate it, I can do textures, I can do...
|
|
I can integrate into a bigger environment with different tasks for every person.
|
|
I'm able to do that, I'm able to do that.
|
|
And I think it can be appreciated because it's also published on the internet and can be verified by the employer.
|
|
I always confuse employee employer, sorry, employer, I would say.
|
|
Okay, so, if you are making 2D or 3D stuff, the process changes a bit.
|
|
It's a lot easier for 2D stuff, so you just have to pick up gym or create if you are hand-drowing something.
|
|
And that's it, you don't need any other software or plugin.
|
|
It's a different story if you are talking about 3D, then you need Blender, you need to read the documentation on the Super Tax Card website.
|
|
They give you the link to a plugin for Blender that acts as a metaware between the Blender file and the Super Tax Card format that will be used in the game.
|
|
So, it adds a new export option and it lets you edit the metadata of your creation.
|
|
For instance, if you are creating a track, you can specify the name, the preview picture and similar stuff.
|
|
You can also specify the checkpoint on the track so that when you fall down the track, you are reset at the checkpoint.
|
|
And, sorry, there's a cross scene.
|
|
Okay, part of the car driving podcast problem.
|
|
Anyway, I forgot what I was saying.
|
|
Okay, I was talking about 3D on Blender.
|
|
So, you can edit all the metadata, you can add the wheels and tell the game that this 3D model is a wheel for a cart.
|
|
This 3D model is the frontal light of the cart, this 3D model and so on and so on.
|
|
You will specify all things that the game needs to know to properly function.
|
|
And then you export the project and you can unload the exported stuff, you can load the exported stuff to the Adon's website.
|
|
This is a general idea of how it works so you can get started.
|
|
If you are starting with 3D, not problem.
|
|
If you are starting with 3D, I highly suggest you to begin by making a character or simply opening the existing source file from the media label.
|
|
And then trying to make the character because it's much easier than a track.
|
|
The track is really more error prone.
|
|
There is so much going on, you need to specify the track, you need to specify the path in order to guide the AI.
|
|
The characters on the track, you need to specify some way, some out the collisions, you need to...
|
|
So, it's much more complex and it's much more difficult to travel shoot too.
|
|
I mean, the developers tried to make a 3D track editor, but they also stayed in the documentation that it's completely broken.
|
|
So, I would say like that, try with Blender, try to make a character, explore the existing projects, explore the existing source file and only after that, maybe try to make a track.
|
|
Anyway, remember to thinkar, we did try and let me know how it goes.
|
|
Maybe we will see new characters from HPR, HPR listeners, who knows.
|
|
It's all from me today and see you next time.
