Hero SDL2

Hero SDL2 provides components and systems to use SDL2 in combination with Hero. Currently, it can do very simple 2D rendering and keyboard input.

Prerequisites

Hero SDL2 needs to have up to date versions of the C libraries SDL2, SDL2_gfx, and SDL2_image. Then, it can be added as a build dependency like other libraries.

Run examples

Hero SDL2 has a few examples within the examples folder.

The rotating-shapes examples shows how to render rectangle shapes and how to rotate / move shapes.

cabal run rotating-shapes

The image-rendering example shows simple image loading / rendering.

cabal run image-rendering

The move-shape example shows how to get keyboard input and lets you move a circle with the arrow keys.

cabal run move-shape
