Fix windows build error
Add Esc and Alt-Enter keyboard shortcuts
Make mouse be grabbed and hidden
Do keypress handling in SDL eventloop
Updated README to include SDL
Use reference for cur_ticks
Remove redeclaration of SwapBuffers
Compile in release mode

@Srinivasa314 this compiles and runs with no problems, however:

input delay / strange input behaviour
the window doesnt open on the main monitor but at 0,0 coordinate and cant really be readjusted

input delay / strange input behaviour

I am not entirely sure. This is what I think.
The player continues to move for a while after input is stopped because it takes some time for friction to stop it. If you increase the friction value then the player stops immediately after input is stopped.

the window doesnt open on the main monitor but at 0,0 coordinate and cant really be readjusted

Fixed it. Now window is centered.

Centering works great now!

Initial input has a good 9 seconds delay though, but if this doesn't happen on your end it may just be my environment.

@Srinivasa314 LGTM! 👍

@HackerPoet

You should consider merging this PR! :)

I found that compiling on mac I had to change the -lGL flag to -framework OpenGl. Even then though it compiled fine but I got segmentation fault when running it. Compiling on Arch linux worked fine, the only thing is that I could not move my mouse and walk at the same time.

I do not have a mac. Can you show the stacktrace?

I think it is because in some desktop environments you cannot use the keyboard and the mouse at the same time. If it is because of that then you can change that setting.

hamdav · 2021-03-14T08:10:17Z

No trace, just segmentation fault (core dumped) I think...

Srinivasa314 · 2021-03-14T08:35:00Z

You can use lldb or any other debugger to get the stack trace. Add -g to CXXFLAGS in the Makefile before compiling so that more information will be available to the debugger.

I also have to add -std=c++11 for it to compile btw, it complains about a bunch of stuff otherwise and gives an error that

Srinivasa314 · 2021-03-17T12:54:48Z

I think I fixed it. Check if it works now.

asukaminato0721 · 2021-11-06T11:27:24Z

NonEuclidean/Makefile

+	rm ${OBJS}
+
+${EXE}: ${OBJS}
+	${LINK} ${LINKFLAGS} $^ -o ${EXE}


After lone debug, In my ubuntu20, I found that L38 change to this could work.

${LINK} $^ ${LINKFLAGS} -o ${EXE}

Hello, where can I get the code that compiles and works on mac please? Thank you.

Fix fractional scaling and sluggish mouse movement

rsmath · 2022-09-11T05:19:50Z

@Srinivasa314 @Srikanth-M-02 could you please tell me how to get the code that will run on Mac?

Srinivasa314 · 2022-09-11T05:42:19Z

Download xcode command line tools
install glew and sdl2 (you can use brew install)
git clone https://github.com/Srinivasa314/NonEuclidean then cd NonEuclidean/NonEuclidean
export CPATH="/opt/homebrew/Cellar/glew/2.2.0_1/include/:/opt/homebrew/Cellar/sdl2/2.24.0/include/"
export LIBRARY_PATH="/opt/homebrew/Cellar/sdl2/2.24.0/lib:/opt/homebrew/Cellar/glew/2.2.0_1/lib"
change the above command depending on where glew and sdl2 were installed
run make all
./NonEuclidean
As of now scenes 4 and 7 dont work properly on my mac

Srinivasa314 · 2022-09-11T05:45:35Z

Is it working @ramanshsharma2806 ?

Srinivasa314 · 2022-09-11T07:12:12Z

Btw scene 4 works if I replace the bunny.obj and suzanne.obj with other obj files
and scene 7 works if I disable GL_LINEAR_MIPMAP_NEAREST and glGenerateMipmap

Sussy-OS · 2022-09-12T12:25:13Z

Would PR #26 work with this? Currently, if you were to put glew-2.1.0 in the directory with the .exe, it would fail to build. #26 fixes this. It would be handy, (with permission) to merge that PR into this one.

ehx-v1 · 2022-11-07T06:38:51Z

@Sussy-OS They're PRs for the same repo anyway, so the permission should already be implicitly there. Would definitely be great if this worked.
