# Basic Usage

Example Scenes:\
Assets/GAS/Mirror-Integration/ExampleSceneMirrorGAS.unity (multiplayer)\
Assets/GAS/Example/ExampleSceneGAS.unity (singleplayer)

## Define your Abilities, Effects, Tags and Attributes\*

Create their Scriptable Objects:

Right click a folder in your editor -> Create -> GAS.\
Create an **ability** GameplayAbilitySO (**GA** SO).\
Create an **effect** GameplayEffectSO (**GE** SO).\
Populate the **effect** with tags and modifiers.\
*(Use ADD MODIFIER button on the bottom of the **GE** SO)*\
Drag the **effect** into the created **ability**'s **effectsSO** field.

*\*Tags, Attributes and GameplayCues SOs must be in the same folder as their library (AttributeNameLibrary, GameplayTagLibrary, GameplayCueLibrary)*

## Attach the Ability to an AbilitySystemComponent (ASC) 

Drag your **ability** into a pre-existent **GroupASC** at Assets/GAS/Resources/DataGroups **OR;**\
Alternatively, create your own **GroupASC**[Data Groups](/gasify/data-groups.md) and drag it there. 

Drag the **GroupASC** into the PrefabPlayer (*GAS/Example/*) **OR;**\
Alternatively, drag the **GroupASC** into a new AbilitySystemComponent.
