Thank you

I just wanna say thank you for creating and realizing this project. This is pretty amazing!!

Does not build today - missing package?

I get this: Unhandled SB-KERNEL:SIMPLE-PACKAGE-ERROR in thread #<SB-THREAD:THREAD "main thread" RUNNING {10005E05B3}>: Error finding package for symbol "OBJECT": The name "STRUCT-TO-CLOS" does not designate any package.

Physics system plans

I see that the physics system is not super extensible at the moment. Leaning in to generic functions and CLOS could make it easier to deal with as long as it wouldn't be too slow, though that could be premature optimization talking.
I did some light refactoring purely for my own benefit here (not change reccomendations)
https://github.com/Drainful/sucle/blob/physics-refactor/src/sucle/physics%2B%2B.lisp

I'm curious about your plans/goals for the physics system, and I'm interested in helping out if you're open to it.

Dirt blocks

Is it intended, that dirt block have height 1/2 now?

Plans for future development

Are you planning to add other minecraftish features, like char models, ui and all other stuff?

Should include detailed d/l instructions

As this isn’t registered in the ql library, you should explain in the installation instructions where to d/l it to, and how to ql load it locally.

GLSL issue

When I try to start sucle, I always get this error for some reason:

Any idea what the issue could be?

Suppose one is a lisp newbie... (like me)

What CL implementation are you using?

Improved config and build instructions wouldn't hurt.

Fix installation process

Does not build today - duplicate definition

I get this fatal build warning today:

; caught WARNING:

Does not starts on OSX 10.11.6 and SBCL 1.4.11

sucle:start crashes on Windows 10 64-bit

I installed sucle per the instructions on my Windows 10 x64 box, and everything works up until (sucle:start), when I get this message:

* (ql:quickload :sucle)

glfw is unfriendly to non-FHS complient systems (e.g. Nix, Guix)

On Guix, trying to quickload sucle, I get this error:

Unable to load foreign library (LIBGLFW.SO.BODGED-586).

This is because Guix (like Nix) does not follow the FHS and the libraries are stored in /gnu/store, with symlinks created to ~/.guix-profile/ if the user installs them.

I can hard-patch the libraries, but this is not ideal.
Any other way?

More generally, why do we need to rely on binary libraries here, why not glfw as provided by the system?

I'm also uncomfortable running a random untrusted binary distributed over the Internet, this is a huge security issue. What do you think?

OpenGL 2.1

Any plans on supporting PCs with OpenGL 2.1? Aforementioned Minecraft supports it and its widespread across old PCs like mine.

Don't know what mInEcRAft is.

plz help.

Cross-platform testing grid

Non standard source formatting often reduces readability

Compare the following 2 screenshots:

Current formatting. Without counting parentheses (or using delimiter coloration) it's unclear how many arguments are being passed to sucle-mp:submit.

Formatted with slime. Indentation makes it clear that it has been called with 1 standard argument and 2 keyword arguments

There seem to be many cases resembling the above. If this is how you prefer to indent your code then feel free to ignore/close, but otherwise I'd be happy to tweak the formatting as I read through.

apt-get install libglfw3-dev

Hi! Just a nitpick, but on Ubuntu 16.04, I needed apt-get install libglfw3-dev (instead of libglfw3 as described in current INSTALL.md) to compile.

Trying to quickload sucle

I think you'll need to put the .asd files in the root of the project to this works, probably.

Help Wanted in refactoring to use vertex arrays

Hello! I am a Lisp beginner, and this project looks like a fun way to tinker with an existing codebase.

However, I have the same issue as #9 , where textures do not appear. glxinfo | grep -i opengl confirms I am using OpenGL version 3.2, which no longer supports display lists. (For other OpenGL newbies like me, I found these online class notes helpful for understanding the difference between display lists and vertex arrays.)

I can confirm my local development setup (using lem) is working, as I can make some changes to things like the sky-color here and re-evaluate it and see my changes.

My current understanding is that the code change will need to be in application/subsystems/sandbox/change-world.lisp, where at the top of the file you find a draw-world function that iterates over all the data in the *g/chunk-call-list* and uses gl:call-list to execute the display list. The equivalent for vertex arrays seems to be something like gl:draw-elements, which i see in use in the draw-vertex-array function in src/opengl/glhelp.lisp.

So it looks like this functionality is (partly) implemented? But I'm not sure how to plug this into the existing code. I'm thinking i'll need to initialize a vao object, and then change set-chunk-display-list to update this vao object, and then call draw-vertex-array in the draw-world function.

I see some code that looks apropos in dump.lisp under the 'drawing' heading, but my first attempts at cargo-culting what i saw there were unsuccessful, so i figured I'd try opening an issue as the INSTALL.md suggested. Any pointers would be greatly appreciated!

Thank you for releasing this! I'm hoping i can see it for myself soon 🙂

I even deleted all the directories to make quicklisp load me a new one.

Should tabs be 1, 2, 4, or 8 wide? Or should spaces be used?
What editor and plugins are recommended?
