Link an Animator parameter to a Variable

NOTE: This script is included in AC v1.74.0 and later.

This script allows you to sync up an Animator parameter's value with an AC component variable. To use it:

1. Attach a Variables component to the Animator, and define a Bool, Integer, or Float parameter that matches the name of the Animator parameter you want to sync with.
2. Set its Link to field to Custom Script
3. Place the script below into a C# file named AnimatorParameterLink.cs
4. Add the component Animator Parameter Variable Link to your Animator component
5. In the component's Inspector, enter the name of the variable/parameter into the "Shared Variable Name" field. If the parameter is only intended to be read - and not set via the variable's value - check "Download Only".

AnimatorParameterLink.cs:

using UnityEngine;
using AC;

public class AnimatorParameterLink : MonoBehaviour
{

	public string sharedVariableName;
	public bool downloadOnly;
	private Variables variables;
	private Animator _animator;


	private void OnEnable()
	{
		variables = GetComponent <Variables>();
		_animator = GetComponent <Animator>();

		EventManager.OnDownloadVariable += OnDownload;
		EventManager.OnUploadVariable += OnUpload;
	}


	private void OnDisable()
	{
		EventManager.OnDownloadVariable -= OnDownload;
		EventManager.OnUploadVariable -= OnUpload;
	}


	private void OnDownload (GVar variable, Variables variables)
	{
		if (_animator == null || variables == null || string.IsNullOrEmpty (sharedVariableName))
		{
			return;
		}

		if (this.variables == variables && variable.label == sharedVariableName)
		{
			switch (variable.type)
			{
				case VariableType.Boolean:
					variable.BooleanValue = _animator.GetBool (sharedVariableName);
					break;

				case VariableType.Integer:
					variable.IntegerValue = _animator.GetInteger (sharedVariableName);
					break;

				case VariableType.Float:
					variable.FloatValue = _animator.GetFloat (sharedVariableName);
					break;

				default:
					break;
			}
		}
	}


	private void OnUpload (GVar variable, Variables variables)
	{
		if (_animator == null || variables == null || string.IsNullOrEmpty (sharedVariableName) || downloadOnly)
		{
			return;
		}

		if (this.variables == variables && variable.label == sharedVariableName)
		{
			switch (variable.type)
			{
				case VariableType.Boolean:
					_animator.SetBool (sharedVariableName, variable.BooleanValue);
					break;

				case VariableType.Integer:
					_animator.SetInteger (sharedVariableName, variable.IntegerValue);
					break;

				case VariableType.Float:
					_animator.SetFloat (sharedVariableName, variable.FloatValue);
					break;

				default:
					break;
			}

		}

	}
