Simple Game Engine in C++ to create Retro games.

About

WHYCPP is a simple, fantacy-console inspired, library to create pixel-art games. The main idea behind WHYCPP is to have fun by coding entire game, without all these fancy features a typical framework offers.

Featues

You can:

• create games in C++, C, JavaScript;
• draw EACH pixel on the screen manually;
• draw primitive shapes;
• load and draw png textures;
• play wav sounds;
• handle keyboard and mouse;
• compile game into Web Page using emscripten.

Requirements

Windows

On Windows you can only develop using MSYS2 and MinGW.

When you have MSYS2 installed, run these commands to install necessary tools:

pacman -S mingw-w64-x86_64-make mingw-w64-x86_64-cmake mingw-w64-x86_64-gcc mingw-w64-x86_64-pkg-config mingw-w64-x86_64-SDL2 mingw-w64-x86_64-SDL2_mixer

Linux

For Debian-based Linux run these commands:

sudo apt install cmake make g++ libsdl2-dev libsdl2-mixer-dev

Mac OS

I suppose you have Homebrew installed.

Run these commands:

brew install sdl2 sdl2_mixer

You may need to activate developer tools: xcode-select --install

How to create game?

For C++

1. Fork template project WHY_CPP_template
2. Write your code in src dir.
3. Just run make in the terminal to compile and run. Template is preconfigured to automatically download the latest release of WHYCPP.

Or

1. Fork this repository.
2. Create a new dir, for example game, with content like we have for example
3. Add line to the CMakeLists.txt: add_subdirectory(game).
4. If you need, you can add to the Makefile new tasks like example-compile and example-run

why_cpp's Issues

std::cout not working on windows SDL2 App

• Create a function facade which uses SDL2 log functions.
• Replace all std::cout, cerr calls to this new log function

Texture import

Importing texture from a PNG file without color-pallete constrains.

Python scripting API

As we have in https://github.com/senior-sigan/JVCR-ECM-01/ we need a python/lua scripting API.

Should be implemented as a python interpereter, not as a library, so we could compile it into JS and run python inside. Like in tic-80.

Reduce CPU usage in game loop

Take a look at http://sdl.beuc.net/sdl.wiki/SDL_DisplayFormat

Rendering optimisation, timing. Maybe delays somewhere?

Add circle shape to draw

We have lines, points, rectangles. But where is a circle??? Or elipse?

Fonts rendering

Add functions to draw some text in the screen.

API:

• text position (x,y)
• text size
• text color
• bacground color
• ? import another fonts (add another resource file)

Text input.

I want to do leaderboard. Now to text input I must use 30 or more ifs. Could you add possibility to normal text input.
