Features

• Provided as a Plugin to easily share code between projects
• Blueprint Friendly, no need to dive into the cpp side, you can implement Abilities right away
• C++ Friendly too! You can easily extend from the provided C++ class or modify the plugin source.
  • GAS Companion aims to be a general base for GAS powered projects without making any game design choices. The system is intended to be subclassed and customized per project needs.
• Not Game specific The plugin doesn't make assumptions about your game design and decisions, and was built to be generic enough to be used in any kind of game.
