OID

A graphics library that is designed from the ground up to use Entity based architecture (entitas.cr). Still a work in progress.

Installation

1. Add the dependency to your shard.yml:

dependencies:
  oid:
    github: spoved/oid.cr

2. Run shards install

Usage

To generate an app shell, use the oid-cli to generate the base system and controllers.

From the root of your project:

cd ./lib/oid
./bin/oid-cli gen <project_name> ../../src

Then simply require the generated main.cr into your entrypoint. Check the TODOs in each of the generated files for places to add your code and examples.

Development

Required tools/libs:

• llvm >= 8
• cmake >= 3.14
• raylib ~> 3.4.0

Mac OSX

or run ./build.sh

Linux

Will add instructions in the future
