sdl_nyan
Tiny SDL2-based library and demo application for rendering animated nyan cats. Rainbows not included, cats only!
Requirements and building
Requires CMake>=3.14, SDL2 and a c11/c++17 capable compiler.
git clone https://github.com/oxmox42/sdl_nyan
mkdir sdl_nyan/build && cd sdl_nyan/build/
cmake .. && make
./sdl_nyan_demo
Usage
Only internal use in the demo application tested so far. Needs more CMake-foo to be installable as "proper" library.
The nyan sprites have been converted to c code and are included in the library,
so there's no need to keep the .png files around.
Create a SDL_Renderer and call make_nyan_sprite_sheet_from_mem(). This
creates a texture containing all 12 rightward-facing nyan sprites.
Use nyan_sprite_rect() to get the SDL_Rect for a specific sprite. This can
be used as the sourceRect for SDL_RenderCopy or SDL_RenderCopyEx.
See the demo on how to make circly, spinny nyans.
Meow!
