In Dimension of The Past (2016) a strange bug occurs: when the player is on any surface to a higher level of water (like the bridge in entrance) his weapon "float" as it if it were under the water.

Resolved by: sudo apt-get install libgles2-mesa-dev.

/src/qurp/WinQuake/platform.pi.c:6:10: fatal error: bcm_host.h: No such file or directory #include <bcm_host.h> ^~~~~~~~~~~~
Not yet resolved properly. Many more follow afterwards. The include path(s) seem to be set correctly, bcm_host.h is indeed found in one of those paths, but somehow the compiler does not find it.

I will continue to investigate how to properly fix these.

It looks like the raspberry pi supports this opengl es extension. it would mean we get away sending half the amount of vertex data we currently do and could potentially improve performance. Providing we aren't cpu bound or converting the float data on the fly makes us so.

Current version has no support for the mouse.

Hello welford,
I built the qurp project on my raspberry pi 1 (Model B) and was running into some issues. The entire building process worked fine without any errors, but when I try and launch the game, it freaks out and doesn't render the world properly. It's really hard to explain stuff like this through text, so I uploaded this unlisted video to YouTube to show what I mean:

https://youtu.be/zcCcejf1Ib8

I hope you can do something with this information, because I'd love to use your sourceport on the pi :)

Hi, welford! And thanks for this Rpi-optimized port of the best Quake game in history! (IMHO) 👍

Could you please add OGG/MP3 music support, please? As you may know, one of Quake's strenght was the music by Trent Reznor, it gave SO much atmosphere to the game!
Efen WAV/FLAC would be right. Whatever music format is better for you.

Thanks!

Hi,
on my RPi 3 Qurp does not save any option 'cause of missing config.txt.
Even if I create new config.txt file in ID1 folder, still Qurp does not save settings.
Also a lot of console commands are not recognized and it seems there is no way to save the display mode selected with "-width" and "-height" options in CLI.
Thanks

Pre-requisites to add to the readme:
libgegl-dev
libgles2-mesa-dev

Though I notice we're compiling for armv6, perhaps the code could detect when we're using a Pi 3 and compile for armv7 ?

I get an error stating that recipe for target 'debugarm/bin/glquake' failed
***[debugarm/bin/glquake] Error 1
Any help? I tried using both options to build.

does not happen in the debug build

I have Raspberry Pi 1 B (first rpi)
For some reason, when compiling at the very end, it gives an error:
platform.pi.c EGL_DISPMANX_WINDOW_T unknown type name

currently nothing plays

Are there instructions for compiling this on Debian on an x86 processor?

I have a possible fix for the keyboard events propagating to the shell
ioctl (pState->kb_input0, EVIOCGRAB, (void*)1);
see https://github.com/kramble/qurp/blob/master/WinQuake/platform.pi.c#L244

Not quite sure of the calling convention, some examples pass a pointer to an int vis
int grab = 1;
ioctl (pState->kb_input0, EVIOCGRAB, &grab);
Which sort-of makes sense, but the one I've used does work.
... ah, just looked at the linux driver evdev.c - it just uses the arg pointer as a flag, so ignore this, I was right the first time.

Unfortunately this breaks Control-C (SIGINT) handling (it just does nothing). Sigh.

Hello,

I would like to ask if it would work without having to use the OPENGL library, and actually a bit like retropie does (retroarch lib).

Would you think that dev could go a bit in this direction? Likely all directions, dev, go on superbe graphics, shadows, superbe magic effects,... but won't work on perfs. of a pi.

SIncerely / best regards,
