digitalmars.D.announce - Basic D Game For New D Gamedevs (glfw 3.3 + openal soft 1.1 + opengl

I have created a basic, and I mean basic, game/engine. I realized 
this would be great for people who are interesting in making 
games in D from the ground up but have no idea where to start.

The elements that are glued together in v1.0.0 are:

- GLFW 3.3
- OpenAL Soft 1.1
- OpenGL 4.1 with GLSL 410

Here is the repository, it is very bare bones: 
https://github.com/jordan4ibanez/d_glfw_test/tree/v1.0.0

I was using this as a learning experience for making games with 
the raw materials and gluing them together as I went, so 
hopefully this can jump start someone's hobby in creating cool 
games while greatly improving on aspects that exist in this 
game/engine. This is translated from a LWJGL tutorial while 
taking a lot of the Java-ness out of it as much as I could and 
replacing it with D's strengths.

I hope you find this useful, and if you end up utilizing this to 
start your game dev journey, I hope you have fun.

Nice work. I get a crash on Windows though.

I am currently installing Windows 10 onto my laptop with an AMD 
Ryzen 5500U so I will be able to fix this for version v1.0.1 :) 
Thank you for letting me know about this, I greatly appreciate it

Another program of yours, 
[Crafter](https://github.com/jordan4ibanez/Crafter), also crashes 
and Windows immediately after being run, and I don't think it's 
because of any of the dependencies.

I appreciate your input! This was actually an oversight in the 
GLFW window context creation order of operations! I have fixed 
this in a new release that should run properly on all the major 
operating systems. Windows seems to be a lot pickier in how you 
go about things. :) Here is the release branch 
https://github.com/jordan4ibanez/d_glfw_test/tree/v1.0.1

Also for Crafter. Well that is what this bare engine was 
originally built for, it will not compile as of the time I am 
writing this, because it originally was utilizing Schveiguy's 
awesome version of Raylib to do all talking to 
drivers/hardware/etc. It is currently taking the first step into 
using the new bare bones engine because I like to get really into 
building the engine and see how it works and what works, it's fun 
for me. The dub.json, imports, logic loop are all horrifically 
incorrect, haha. When the time is right, I will make a new 
announcement about it, but for now, or until you see a commit 
like "get this piece of junk working", it is extremely unusable 
and uncompileable.

I just wanted to ensure that this was solved in the basis so that 
everything is correct and no one will have problems working from 
it, for creating whatever they want. :D

I am doing many tests on this engine's bare bones state, even 
though it may not look like it. I might update this later with a 
~mysterious~ thing I am testing.

Here is the new branch: 
https://github.com/jordan4ibanez/d_glfw_test/releases/tag/v1.0.2

I think I'm done with it now, that should be a good baseline.

I was very wrong, I found a HUGE oversight in the Z_NEAR and 
Z_FAR for the camera.
This is https://github.com/jordan4ibanez/d_glfw_test/tree/v1.0.3

The Z_NEAR was way too small.
The Z_FAR was way too big.

This was a side effect of prototyping. Causes: GL float 
calculation errors! Z fighting literally everywhere. It is fixed 
in 1.0.3.

I suppose I'll keep updating this if I find anything else, but 
now it seems to be functioning as expected. It would be much 
easier if I could edit the main forum post as I would not be 
bumping this back to the top of the forum.
