# 3d Thingy

This is my experiment with creating a 3d game using SDL 2.

I do all the 3d-ness myself, and I use SDL2 only for drawing points on a window.

![here it is running](screenshot.png)

You can use arrow keys to move around, or fly and land with `w` and `s` keys.

## Compiling

    $ sudo apt install git gcc make pkg-config libsdl2-dev

    $ git clone https://github.com/Akuli/3dthingy

    $ cd 3dthingy

    $ make

    $ ./3dthingy

I have no idea what you need to do if you don't have apt.

## Running IWYU

**You don't need to do this to run the program.**

This is for developing program.

IWYU checks whether the source code files have the correct includes.

1. Install cmake

        $ sudo apt install cmake

2. Add LLVM 8 stuff to your `sources.list` from https://apt.llvm.org and

   install the stuff:

        $ sudo nano /etc/apt/sources.list

        $ sudo apt update

        $ sudo apt install llvm-8-dev libclang-8-dev clang-8

    Again, I have no idea what you should do if you don't have apt. Sorry.

3. Clone IWYU and compile it

        $ git clone https://github.com/include-what-you-use/include-what-you-use ~/iwyu

        $ cd ~/iwyu

        $ mkdir build

        $ cd build

        $ cmake ../include-what-you-use -DCMAKE_PREFIX_PATH=/usr/lib/llvm-8

    **If you get a CMake error**, look for `llvm-something` in the error

    message. If the `something` part is NOT `8`, then the build is using

    the wrong LLVM version, and you need to make sure that the `-D` part

    of the `cmake` command ends with 8. The same command is in IWYU's

    README with 7 instead of 8.

4. Compile the IWYU

        $ make -j2

    This takes a long time and about a gigabyte of RAM because IWYU is

    written in C++. I don't like C++.

5. Run the IWYU

        $ cd ~/path/to/3dthingy

        $ export IWYU=~/iwyu/build/bin/include-what-you-use

        $ make iwyu

    If you get an error about IWYU not finding `` or some

    other include file, try this instead:

        $ export IWYU='~/iwyu/build/bin/include-what-you-use -I/usr/include/clang/8/include'

        $ make iwyu

    With this, sometimes IWYU suggest `"stdbool.h"` instead of

    `` to me, but at least it's better than nothing. Adding

    `#include ` instead of copy/pasting IWYU's suggestion

    works, too.
