❓ What is it?

Tired of animator parameter headaches? This tiny Unity package eliminates you from:

• 🚫 Manually defining string constants for Animator parameters;
• 🚫 Manual caching hashes with Animator.StringToHash();
• 🚫 Remembering names of Get/Set methods for Animator's parameters;

Instead, enjoy the 3-simple-steps:

• Define a strongly-typed parameter from the package;
• Pass its string name (must match Animator parameter name);
• Use .Value to get/set values instantly;

It effectively hashes & caches parameter name and reuses it automatically to get/set values with maximum performance possible. For you it will be as simple as the following:

_isMoving = new BooleanParameter("is_moving", _animator);  
_isMoving.Value = true; // Done! 🎉

💾 Installation

• Open Unity Package Manager (Window > Package Manager) OR (Window > Package Management > Package Manager) in Unity 6;
• Click "+" → "Add package from git URL";
• Paste this repo's URL;
• Hit Install;

🚀 Getting started

Step 1: Define Parameters

Add the namespace and declare your parameters:

using MadeYellow.AnimatorParameter;

private BooleanParameter _isMoving;
private FloatParameter _velocity;
private TriggerParameter _onLand;

The package support those types of parameters:

• BooleanParameter for Bool parameters;
• IntegerParameter for Int parameters;
• FloatParameter for Float parameters;
• TriggerParameter for triggers (best suited for events, like 'fall', etc.);

Basically, it's the same types that are supported by Unity's Animator.

Step 2: Instantiate Parameters

Initialize them in Awake() or Start() with name & Animator reference:

private void Awake()
{
    _animator = GetComponent<Animator>();

    // Create instances of parameters like this
    _isMoving = new BooleanParameter("is_moving", _animator);
    _velocity = new FloatParameter("velocity", _animator);
    _onLand = new TriggerParameter("on_land", _animator);
}

There are just two arguments among ANY of the AnimatorParameter:

• codename It's just a string. It MUST be have same name that you've defined inside Animator controller in Unity Editor. No need to define constant, just pass a string right into the constructor. Parameter will do the rest for you.;
• animator Well, this is the Animator that you want to pass values into;

Step 3: Use Parameters Effortlessly

Now you might GET or SET values by just calling .Value property of your parameter!

private void HowToSetValues()
{
    // This is how you SET values in the Animator
    _isMoving.Value = true; // Pass your BOOL value here
    _velocity.Value = 10f; // Pass your FLOAT value here

    // When you need to activate trigger - you may easily access it
    _onLand.Trigger();
}

private void HowToGetValues()
{
    // This is how GET values from the Animator
    var isCurrentlyMoving = _isMoving.Value;
}

🎯 Full Usage Example

using MadeYellow.AnimatorParameter;
using UnityEngine;

public class AnimatorParameterExample : MonoBehaviour
{
    private Animator _animator;

    // STEP 1. Define all the parameters you need once
    private BooleanParameter _isMoving;
    private FloatParameter _velocity;
    private TriggerParameter _onLand;

    private void Awake()
    {
        // STEP 2. Cache Animator
        _animator = GetComponent<Animator>();

        // STEP 3. Create instances of parameters (define names right in the constructor, no need to cache them) and pass that animator into them
        _isMoving = new BooleanParameter("is_moving", _animator);
        _velocity = new FloatParameter("velocity", _animator);
        _onLand = new TriggerParameter("on_land", _animator);
    }

    private void SomeSetMethod()
    {
        // Now somewhere in your script you may use those parameters to update their values
        _isMoving.Value = true; // Pass your value
        _velocity.Value = 10f; // Pass your value

        // When you need to activate trigger - you may easily access it
        _onLand.Trigger();
    }
}

Also you may fetch current value of parameter FROM Animator by getting value of .Value property of your parameter:

private void SomeGetMethod()
{
    // That will fetch a value of "is_moving" parameter from the animator
    var isCurrentlyMoving = _isMoving.Value;
}

⚡ Why You’ll Love It

• 🧠 Zero name caching – Define names once in constructors;
• ⚡ Auto-hashing – Package uses Animator.StringToHash() under the hood;
• 💎 Clean syntax – .Value for get/set, .Trigger() for events;
• 🚀 Performance optimized – Future plans for value-diff checks;
• 📦 Tiny & dependency-free – Minimal footprint;

🗺️ Roadmap

Planned features

• Add a way to smoothly change Value of FloatParameter in Animator;

Want me to add something OR found a bug?

Please add an issue and describe your feature request or bug. I will add a feature if consider it usefull, and for sure will fix bugs, 'cause I'm using that package myself in my games.
