[Sugar-devel] SugarGames, GTK3 and fonts ?

[Alan Jhonn Aguiar Schwyn]

SugarGames is a "bit" deprecated but works. There are a lot of activities that uses it.In my case, all my activities (except one) uses SugarGames library.
To do a toolbar, only add a few lines in activity.py like the patch attached.I test on sugar-build and works good!
You can use PyGame directly, but when activity loads, it open another window andyou not have the sugar toolbars.
And yes.. Pygame is the better python game library!

I've applied the patch : but, as Gonzalo Odiard made me notice, perhaps I'd better not rely on deprecated sugargame library any more : right ?So I think I have to use plain gtk3 fonts and canvas (is there one ? I did not find any note on the official python GTK3 tutorial : http://python-gtk-3-tutorial.readthedocs.org/en/latest/), and also make an activity class for the integration with the olpc (toolbar).

Or can I use Pygames without the sugargame layer ? Because PyGame make animations coding easier : I remember that in GTK2 I had some pains for using threads : because in PyGTK2 there was a kind of restriction (though I can't remember which) with threads coding.

Thank you very much : I'll apply those changes today.

Copy the patch to your GIT folder and do:
git apply 0001-....
After, if you like the changes, can commit them.
In Pygame, when you do:


font = pygame.font.Font(None, 30)
It selects the default font of the system (I don't know the name).
If you want to see all fonts:


all_fonts = pygame.font.get_fonts()
Or load a specific font:
font = pygame.font.Font("path/to/the/font/my_font.ttf", 30)
Regards!

Thanks for your patch Alan : how must I apply them ? (I have not used patch before).
Yes, I am very happy that you purpose me to develop the GTK2 version :)I have tried to do my best to code in respect with pep8 (using autopep8 program) and pyflakes.



What are the default fonts in Sugar ? (Sorry, I did not look for standards)

I have this patchs for you.One to evite track .pyc and other extensions that no have sense add to git.
The second, it's a few of changes for that you code works with Sugargames


library.You must make another few of changes. I use the default font, for example.
If you want, you can do the GTK3 version and I translate to GTK2 :-)
Regards!

No problem.In fact, tusmath is a c game, and that is a problem,because is not multiplatform.Go ahead, but look at it to see what they do.

Oups sorry
I did not notice that there was a similar game.
In fact, I am lacking ideas.

If you add a mode similar to tuxmath,may be we can kill that game finally......
While the pedagogy of tuxmath is not the best,every deployment ask for it

Thank you.
So I think I'll try to develop for both GTK2 and GTK3.



It's a game, and I have nearly finished it for OLPC 0.100 : https://git.sugarlabs.org/hittheballs/hittheballs

It's a very simple game where balls with operations goes across a screen area, and user must choose good one(s).

My case:
- I use Ubuntu with sugar-emulator 0.96 to test GTK2 activities. Only with a link of my GIT folderto ~/Activities and I'm ready to test it!







- For latest: I download the sugar-build and works. But in certain moment, it begin with a grade of complexthat I don't like. Now with the broot system, it's a bit complicated. But "is what you get".







To make a GTK2 and GTK3 activity you need make 2 codes, and maybe, two differentactivities. There are ways in python to check wich version of gtk you have in the systemand run a gtk2 or gtk3 activity. But that needs extra work to update both "branchs".







>So what do you advice me ? (developping in GTK2, GTK3, and/or web activity)
I don't know wich type of activity you want to do. It's a game?

Hello
In fact I am developping against GTK3 because I have the latest sugar-build, which holds the 0.100 version.
Otherwise, I can download the 0.94 or some versions under in SugarOnAStick format, or in a VirtualBox format : but this way I have difficulties for transferring easily the project from my host system to the guest sugar one. I tried, in VirtualBox, to use the guest additions in order to share a folder between the host and guest systems (some years ago), but I did not manage.








Also, I don't know how to develop the application so that it supports both gtk2 and gtk3.
And I was also planning to port the activity to a web acitvity, instead of a gtk one, but it may not be available to many OLPC that way. And I don't know where to start.








So what do you advice me ? (developping in GTK2, GTK3, and/or web activity)
Regards.

Hi,
You only will make a GTK3 version?The latest sugar (0.100) is not used in any deployment:in all countries we have Sugar 0.94 or less.
Would be good have a GTK2 version of that activity.








Regards!

Thank you very much.








I'll try with Python/Cairo/Gtk3.

2013/9/24 Gonzalo Odiard <gonzalo at laptop.org>

If you are not porting a existing olpcgames application,I suggest you use something else.
You can use any of the html5 frameworks, or plain python/cairo stuff.sugargames de not have to much development, 
and pygame/gtk do not work really well together.

Hello everyone,
As I am developping my game HitTheBalls for sugar 0.100 (I have, I think, the latest sugar-build), I am planning to switch it from OLPCGames 1.6 to sugargames.











But the sugargames tells that pango font is not supported. So, what is the best way to get started with fonts in SugarGames ? Do you have some links ? I searched over the web, and I found tutorials for Gtk3 and PangoCairo, but I don't know if these can work with SugarGames.
