Running

The program does not take any commandline arguments and must be run from the root project directroy. For example, when building on Linux to the out directory the run command is ./out/A5.

Building

This project is built with cmake. It depends on SDL2, glm, and glew.

Windows

• Download and extract the latest versions of SLD2, glm, and glew
• For each of the libraries, add a cmake conifg file setting the paths to the libraries and header files (SDL2_INCLUDE_DIRS, SDL2_LIBRARIES, etc.)
• Open the project folder in Visual Studio
• Add or modify the variables in CMakeSettings.json (SDL2_DIR, GLM_DIR, and GLEW_DIR) to point to where the libraries are installed
• Before running, ensure SDL2.dll is on the system path

Linux (Ubuntu)

Install the dependencies:

• sudo apt install libsdl2.0-dev
• sudo apt install libglm-dev
• sudo apt install libglew-dev

For the glm headers to be recognized you need to copy FindGLM.cmake from https://github.com/Groovounet/glm-deprecated/blob/master/util/FindGLM.cmake to ~/.local/lib/cmake/FindGLM.cmake

Configure cmake and build

• cmake -DCMAKE_BUILD_TYPE="Debug" -Bout
• make -C out

Assets

I created all the assets that I used myself.

Textures

I generated the font texture using the Codehead’s Bitmap Font Generator tool found at http://www.codehead.co.uk/cbfg/. I generated the other textures using a combination of GIMP and Clip Studio Paint.

Sounds

I created the fail and pass sounds in LMMS and recorded the collision sound with Audacity.

Models

I generated the .obj and .mtl files using Blender. For the models that did not come from .obj files (the tombstone and tree) I generated the vertex buffer data in code.

Objectives

1. UI with keyboard shortcuts to control in game time.
2. Perlin noise to generate terrain heightfield.
3. Bump Mapping using heightfield.
4. Shadow mapping.
5. Reflection using stencil buffer.
6. Transparency with alpha blending.
7. Simulate smoke with a particle system.
8. Skybox.
9. Depth of field.
10. Synchronize sound effects with game events.
