# Gameplay Ability System for Unity Gameplay Ability System for Unity (or GAS for short) is a Unity framework for creating games which contain any kind of abilities (e.g. DotA, Skyrim). The framework helps to simplify the interaction between components in a unified manner.
The approach for this is taken from that used by Unreal's Gameplay Ability System, but implemented in Unity using the Data-Oriented Technology Stack (DOTS) where possible.
- Head over to Releases and download the latest version.
- Import package into your Unity project
The demo uses the Unity 3d Game Kit, and showcases an implementation of the attribute system for tracking health, mana, etc. The conversion is not complete, so expect it to be buggy.
To understand how everything ties together, go through the code in the MyGamelpayAbilitySystem folder. Raise an issue if you need help.
More detailed documentation/code layout will be added in a later release.
The following functionality will be implemented in GAS:
Attribute System [Done]Attribute modifiers [Done]- Gameplay Tags [WIP]
- Gameplay Effects [WIP]
- Interaction between Gameplay Effects and Gameplay Tags (e.g. for "dispel" spells) [WIP]
- Abilities
- Interaction between Abilities and Gameplay Effects
- Visual display of abilities (e.g. an "ability bar")
- Visual display of cooldowns (e.g. on an "ability bar")
- Visual display of active gameplay effects
- Sample code showing how to restrict which gameplay effects are displayed (e.g. on a "status bar")
- Targetting system (e.g. single-target, multi-target, intelligent target selection, targettability feedback)
- Customised definition of Ability pre-casting checks
- Ability Combos (e.g. providing some method of defining ability sequences and then executing abilities based on some condition)
- Nicer/more designer-friendly way of defining abilities and effects
- Nicer/more designer-friendly way of defining character stats
- Networking capability (prediction, replication, synching)
