What is Flexi?

Flexi is an ability system framework for Unity.

The basic concept is:

• Flexi has done some general low-level logic.
• Programmers can directly jump into extend with Flexi, and create your gameplay ability system.
• Then designers can use the graph view editor to create/edit ability.
• At runtime, load these abilities and run with built-in runner.

P.S. Flexi is inspired from Unreal GAS (Gameplay Ability System), but not the same concept.

Features

• Customizable: Flexi only do low-level things. So you have space to implement your own gameplay.
• Stat & Modifier: With stat refresh process, modify unit stats with abilities.
• Built-in ability runners: Start from easy and not make your hands dirty.
• Node-based ability editor: Built with GraphView and UIToolkit.
• OOP approach: Not rely on Unity. Not singleton approach.
• ~~Macro: Reuse your partial graphs~~ (Failed to find GC free approach. Suspend until main feature finished.)
