# SDL2::Raw [](https://travis-ci.org/timo/SDL2_raw-p6) [](https://ci.appveyor.com/project/timo/SDL2_raw-p6/branch/master) A low-sugar binding to SDL2. ## Synopsis ```perl6 use SDL2::Raw; die "couldn't initialize SDL2: { SDL_GetError }" if SDL_Init(VIDEO) != 0; my $window = SDL_CreateWindow( "Hello, world!", SDL_WINDOWPOS_CENTERED_MASK, SDL_WINDOWPOS_CENTERED_MASK, 800, 600, OPENGL ); my $render = SDL_CreateRenderer($window, -1, ACCELERATED +| PRESENTVSYNC); my $event = SDL_Event.new; main: loop { SDL_SetRenderDrawColor($render, 0, 0, 0, 0); SDL_RenderClear($render); while SDL_PollEvent($event) { if $event.type == QUIT { last main; } } SDL_SetRenderDrawColor($render, 255, 255, 255, 255); SDL_RenderFillRect($render, SDL_Rect.new( 2 * min(now * 300 % 800, -now * 300 % 800), 2 * min(now * 470 % 600, -now * 470 % 600), sin(3 * now) * 50 + 80, cos(4 * now) * 50 + 60)); SDL_RenderPresent($render); } SDL_Quit; ``` ## Status There's a bunch of functions and structs already covered, but there's also a whole bunch of things I haven't touched at all. If you need any specific part of the API covered, feel free to open a ticket on github or even a pull request! ## Installation |Platform|Installation| |-|-| |Ubuntu 14.04 and above|`sudo apt install libsdl2-dev`| |Fedora 25 and above|`yum install SDL2-devel`| |Arch Linux|`pacman -S sdl2`| |Gentoo|`emerge -av libsdl2`| |macOS|`brew install sdl2 pkg-config`| |Windows|https://libsdl.org/download-2.0.php| ## Examples ### Snake  A simple Snake game. Control it with the arrow keys, guide your snake to eat the red circles, and avoid running into your tail. This code uses `Cairo` to create the images for the snake's body and tail. ### Particles  A very simple particle system that spews white pixels from a central point that get pulled down by gravity and bounce on the floor. ### Shooter  A more complicated game. Control it with the arrow keys and hold the spacebar to fire. The code also uses `Cairo` to render the player's spaceship and the enemy spaceships. In generating the starfields it shows how to render to a texture with `SDL2`. ### White Noise Just draws random white and black pixels to a texture and displays it.
