On Android SDL_RWFromFile cleverly reads from the APK archive's assets folder via the JNI. This is great, but for streaming music it's a problem because it's not thread-safe. This shouldn't surprise anyone: streaming data from a zip file, through java, the JNI, SDL, SDL_mixer... it's a recipe for disaster. As a result I'm exporting the files I want to stream to the sdcard first, then streaming them (safely) from there. At least that's the idea. Trouble is Mixer_LoadMUS itself calls upon SDL_RWFromFile, hence Mixer_LoadMUS("/sdcard/data/music.ogg") calls SDL_RWFromFile("/sdcard/data/music.ogg") which, unless I've very much mis-read the situation, goes looking for "/sdcard/data/music.ogg" in the assets folder of the APP (?). The code that does this trick is *line 448 of SDL_rwops.c **#if defined(ANDROID) rwops = SDL_AllocRW(); if (!rwops) return NULL; /* SDL_SetError already setup by SDL_AllocR</pre> William Dyce 2012-05-25T23:12:02 http://permalink.gmane.org/gmane.comp.lib.sdl/56442 <pre>Hello !

However, you could just use glColor4f(r, g, b, a); prior to calling the write_left_aligned function. The color will be as set without needing to reload the textures.

I have a minor tweak that I think is an improvement. If you pass some RGB values to void Text_ure::write(float x, float y, float lh, float r,float g,float b), then you can dynamically change the color of the font without having to reload it. Just make sure you pass a white color to TTF_RenderText_Blended when the glyph images are being created initially. And you can pass RGB values to write_left_aligned so it in turn can pass them to Text_ure::write. That leaves you with: Code: void write_left_aligned( // write Text_ure *Lettercase[], // with letter case const char* s, // input C string float top, float left, // upper left corner float fontsize, // size float lineheight, // line height factor - 1 is normal float kerning, // letter spacing factor - 1 is normal float width, // column width, float r,float g,float b) //Font color And that o</pre> Trev 2012-05-25T21:15:26 http://permalink.gmane.org/gmane.comp.lib.sdl/56438 <pre>Gabriel convinced me to file this patch in bugzilla, so I did: 1505. I noted this as critical as it's necessary for iOS. Other bugs of note in SDL 2.0, if we are keeping a list: 1174, 1320. Both have people assigned to them.

They were in the mailing list, not bugzilla, as we were putting up dualing patches. For reference, here's mine: http://www.klinksoftware.com/download/SDL_iOS_event_patch.diff It fixes on thing in rendering that would make the messages come at bad times, and then creates a new callback mechanism for events. If you register it, then all events happen in callbacks (and you can tell it to put them on the queue, if you wish.) dim3 does this, it only responds to the iOS messages and puts the rest back on the queue. It also creates a number of must-do-in-callbacks for iOS events (active/deactive/in background/in foreground/memory low/halt.) Other fixes will need to be done for game center (somebody already discussed this.) It would be trivial to put in the android messages in this framework.

Preloading the glyphs from a font to a texture set and assembling on the fly instead seems to work alright for me. The relevant parts I've mashed into the example program below (c++/sdl2). But this approach is only for game text. It's not great for regular applications where the standard OS widgets are familiar, complete and comfortable for people. So, for the text areas and things, you might want to be using a GUI library such as GTK+... but if you do choose to render letters as individual textures, feel free to have at the code here (note the paths to fonts at lines 102-105). http://codepad.org/QS26ciMD On Thu, May 24, 2012 at 10:56 PM, Trev &lt;trevor&lt; at &gt;lackeyccg.com&gt; wrote: _______________________________________________ SDL mailing list SDL&lt; at &gt;lists.libsdl.org http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org </pre> Chris Bush 2012-05-25T17:26:59 http://permalink.gmane.org/gmane.comp.lib.sdl/56435 <pre>Sorry for the off topic statement, but I would be interested in getting Multitouch working on Windows 7 (it doesn't seem implemented yet) if you might be able to provide some guidance.

From README.iOS: ============================================================================== Notes -- Keyboard ============================================================================== SDL for iPhone contains several additional functions related to keyboard visibility. These functions are not part of the SDL standard API, but are necessary for revealing and hiding the iPhone's virtual onscreen keyboard. You can use them in your own applications by including a copy of the SDL_uikitkeyboard.h header (located in src/video/uikit) in your project. int SDL_iPhoneKeyboardShow(SDL_Window * window) -- reveals the onscreen keyboard. Returns 0 on success and -1 on error. int SDL_iPhoneKeyboardHide(SDL_Window * window) -- hides the onscreen keyboard. Returns 0 on success and -1 on error.

I generally render the text to a software surface, copy it to a texture and render it using SDL, I don't think there's a way around it because SDL_ttf is fundamentally CPU centered and rendering GPU centered, and you have to bridge those eventually...if there's a lot of text or it is constantly changing, maybe you can do the glyphs thing (uploading all symbols to a texture and render them "by hand"), but it really depends on the application you are developing. You could, in theory, render fonts using only geometry or shaders, but it seems the technology is not there yet: http://stackoverflow.com/questions/5262951/what-is-state-of-the-art-for-text-rendering-in-opengl-as-of-version-4-1 </pre> Gabriel Jacobo 2012-05-25T13:47:18 http://permalink.gmane.org/gmane.comp.lib.sdl/56427 <pre>I personally am torn, because on the one hand, this project deserves full time attention, but on the other hand I need to get contract work to make sure there's food on the table. :) If somebody does want to step up and manage SDL, I'll be happy to go over in detail what that means and if they still can and want to, we can start training and transition. :) See ya!

For instance, the iOS patch stuff -- there's something like 3 competing patches, and unless we want to have some kind of vote system, nobody but a project leader can solve these problems. This isn't an ego problem, there are multiple ways to do this patch, and each has pros and cons. The next hurdle is who could do this? Nobody is asking me, and I'd turn them down because I have my own projects (and the big one is another project with a community that needs it!), and the very reason I'm using SDL is to make it easier on me. I suspect we are all like that. As I said before, Sam gave us a lot and owes us nothing. Same with Ryan. Nobody should be demanding anything. So, this might seem defeatist, but right now I'd more vote for just finding a way to get in the patches that'll make SDL 2 useable and worry about the future later.
