About

This is a combination of game, visual novel, simulation, and mathematics study.

Compiling

You need Make and GCC. Navigate to project root and execute

make

The executable is ada in project root. To play run

./ada

Game Center

This is a collection of simple games.

Slide puzzle

Status: broken.

2048

Status: broken.

Design

• Don't track cursor position.
• Only get cursor position when mouse clicked.
• Write TODO as the last part in a comment.

Game Testing

What to test?

• No way to procedurally test visuals. So we won't test any render function.
• Test only init and update functions, for now.
• We programmatically click mouse, press key, move cursor, and resize window.

How to test module m?

• Create m_test/ dir inside src/.

• Create m_test.c, include game.h, m.h, and another deps.

• Create m_test_run() in m_test.c where we run all test suite and then report.

• Create helpers key_press() and key_release() to simulate pressing (releasing) key.

• Copy main.c and game.c to m_test/ dir.

• Remove unnecesary stuff in game_init() in game.c.

• Add glfwWindowHint( GLFW_VISIBLE, GLFW_FALSE ) to hide the window. We don't need window.

• Remove game loop from main.c and forward declare m_test_run() from m_test.c

• Call m_test_run() in main().

• Create new Makefile and manually write necessary stuff for linking with our new main.c and game.c.

• Since each module testing has different pattern, we better hard code the Makefile.

• Place the executable in project root because of relative path.
