References

Introduction

References are how we expose fields in MonoBehaviour scripts that allow us to assign a variable ScriptableObject. They're wrapped in a separate class because you can also choose not to use a ScriptableObject at all, and instead write a constant value in the inspector.

This is the default view, which allows us to assign a Variable.

You can click on the icon to the left of the field to change state.

"Use Constant" allows us to assign a value directly.

Script Reference

To create a Reference field in your MonoBehaviour script, simply declare it like you would any other field

public BoolReference boolValue;

Or use the [SerializeField] attribute if it's not public

[SerializeField]
private BoolReference boolValue;

You don't have to care whether the Reference is using a constant or a variable, simply reference the Value property

T Value { get; set; }
