Using This Base Code

Before you dive into the code, it helps to understand the overall structure of this repository.

• Files you should read and/or edit:
  • main.cpp creates the game window and contains the main loop. You should read through this file to understand what it's doing, but you shouldn't need to change things (other than window title and size).
  • Game.*pp declaration+definition for the Game struct. These files will contain the bulk of your code changes.
  • meshes/export-meshes.py exports meshes from a .blend file into a format usable by our game runtime. You will need to edit this file to add vertex color export code.
  • Jamfile responsible for telling FTJam how to build the project. If you add any additional .cpp files or want to change the name of your runtime executable you will need to modify this.
  • .gitignore ignores the objs/ directory and the generated executable file. You will need to change it if your executable name changes. (If you find yourself changing it to ignore, e.g., your editor's swap files you should probably, instead be investigating making this change in the global git configuration.)
• Files you probably don't need to read or edit:
  • GL.hpp includes OpenGL prototypes without the namespace pollution of (e.g.) SDL's OpenGL header. It makes use of glcorearb.h and gl_shims.*pp to make this happen.
  • make-gl-shims.py does what it says on the tin. Included in case you are curious. You won't need to run it.
  • read_chunk.hpp contains a function that reads a vector of structures prefixed by a magic number. It's surprising how many simple file formats you can create that only require such a function to access.
  • data_path.*pp contains a helper function that allows you to specify paths relative to the executable (instead of the current working directory). Very useful when loading assets.

Changes from Base0

• export-meshes.py now supports exporting various subsets of points, normals, colors, textures, and edge lines (based on export filename).
• export-meshes.py now exports just the referenced meshes (by mesh name).
• export-scene.py is a new export script which writes the transform hierarchy (by object name) and mesh references for each object (by mesh name).

Asset Build Instructions

In order to generate the dist/crates.pnc file, tell blender to execute the meshes/export-meshes.py script:

blender --background --python meshes/export-meshes.py -- meshes/crates.blend dist/crates.pnc

In order to generate the dist/crates.scene file, tell blender to execute the meshes/export-scene.py script:

blender --background --python meshes/export-scene.py -- meshes/crates.blend dist/crates.scene

There is a Makefile in the meshes directory that will do this for you.

Runtime Build Instructions

The runtime code has been set up to be built with FT Jam.

Getting Jam

For more information on Jam, see the Jam Documentation page at Perforce, which includes both reference documentation and a getting started guide.

On unixish OSs, Jam is available from your package manager:

	brew install ftjam #on OSX
	apt get ftjam #on Debian-ish Linux

On Windows, you can get a binary from sourceforge, and put it somewhere in your %PATH%. (Possibly: also set the JAM_TOOLSET variable to VISUALC.)

Libraries

This code uses the libSDL library to create an OpenGL context, and the glm library for OpenGL-friendly matrix/vector types. On MacOS and Linux, the code should work out-of-the-box if if you have these installed through your package manager.

If you are compiling on Windows or don't want to install these libraries globally there are pre-built library packages available in the kit-libs-linux, kit-libs-osx, and kit-libs-win repositories. Simply clone into a subfolder and the build should work.

Building

Open a terminal (or x64 Native Tools Command Prompt for VS 2017 on Windows), change to the directory containing this code, and type:

jam

That's it. You can use jam -jN to run N parallel jobs if you'd like; jam -q to instruct jam to quit after the first error; jam -dx to show commands being executed; or jam main.o to build a specific file (in this case, main.cpp). jam -h will print help on additional options.
