A Simple Rough-like game (MSU CG course, A1 variant)

This is an implementation of a simple rough-like game with software rendering.

Installing dependencies

Number of dependencies is minimized, so the only required libs are xcb-shm and xcb. They can be installed:

• On Debian derivatives (e.g. Debian/Ubuntu/Mint): apt update && apt install libx11-xcb-dev libxcb-shm0-dev
• On Arch Linux (and derivatives): pacman -S libxcb
• On Void Linux: xbps-install -S libxcb-devel

It also requires GNU or BSD make, GCC compiler and pkg-config Blending code requires SSE4.1

Building and running

This program can be run with

make run -j$(nproc)

To compile a program you just need to

make -j$(nproc)

Gameplay

• w -- move forward
• a -- move left
• s -- move backward
• d -- move right
• DEL -- reset game
• ESC -- exit game
• +/= -- zoom-in
• - -- zoom-out
• SPACE -- action (open exit)

Your goal is to find the way though 10 randonly generated levels. (If there's a file named data/map_N.txt then it is loaded as a map instead of generating a random one) Levels contains traps (spikes) that damages you. Traps are activated randomly, but have a very short invactive period after activation.

There are also 4 types of poison placed around the level:

• Big healing poisons -- gives you extra live
• Small healing poison -- gives you a half of a live
• Small invincibility poison -- makes you invulnurable for 1 second (every posion adds one second)
• Big invincibility posion -- same, but gives you two seconds

Taken damage shortens invincibility duration.

Exits from level can be closed, in this case there's a key randomly placed in level. When you have a key you can open a door with a space button.

Map is initially hidden until player sees it. Visibility is implemented via ray casting on tile map.
