Unity DOTween Float - C#

Introduction

Unity DOTween is an extension that allows you to animate values in Unity. This extension comes with a lot of features that make it easy for developers to animate values without having to write a lot of code. One of the features is the ability to animate float values.

This guide will introduce the basics of animating float values in Unity using DOTween.

Prerequisites

• Basic knowledge of Unity.
• Basic knowledge of C#.

Using DOTween

DOTween is available as a Unity asset package, which can be installed from the Unity Asset Store. After installing the package, you can import it to your project.

To animate float values, we first need to create a DOTween Tween object. A Tween object represents a single animation. The following code snippet creates a Tween object that animates a float value from 0 to 1 over a duration of 1 second.

using DG.Tweening;

public class MyAnimation : MonoBehaviour
{
    private void Start()
    {
        float startValue = 0f;
        float endValue = 1f;
        float duration = 1f;

        // Create a Tween object
        Tween myTween = DOTween.To(() => startValue, x => startValue = x, endValue, duration);

        // Start the animation
        myTween.Play();
    }
}

In the above code snippet, we first define the start value, end value, and duration of the animation. We then create a Tween object by calling the DOTween.To() method. The first argument is a lambda function that returns the start value. The second argument is a lambda function that updates the start value during the animation. The third argument is the end value, and the fourth argument is the duration of the animation.

Finally, we call the Play() method of the Tween object to start the animation.

This code defines a simple Tween object that animates a float value. However, DOTween provides a lot more features that can be used to customize the animation.

Conclusion

In this guide, we introduced the basics of animating float values in Unity using DOTween. We created a Tween object and started the animation by calling the Play() method. DOTween provides a lot of features that make it easy to customize the animation, which can be explored in the DOTween documentation.
