Smooth change of light range

[e-x]

Hello!
How to make , when you press the J key, smoothly changed range

if (Input.GetKeyDown(KeyCode.J))
{
lightT.range = Mathf.Lerp(startRange, endRange, speedRange);
}

in my case, everything happens instantly, you can example?
Thanks

Unity - Manual: Coroutines

Unity - Scripting API: Mathf.Lerp

Here’s all the documentation you need to do it.

I wouldn’t touch coroutines for this because it’s just unnecessary complexity, especially if you plan to possibly interrupt or reverse the transition.

Instead:

Fading, simple and easy:

How can I fade in/out a canvas group alpha color with duration time ?

Don't use Mathf.Lerp(). Use Mathf.MoveTowards(). And definitely DO NOT USE COROUTINES (see my post above). make some member variables: private float desiredAlpha; private float currentAlpha; The work: void Update() { currentAlpha = Mathf.MoveTowards( currentAlpha, desiredAlpha, 2.0f * Time.deltaTime); } Now, wherever you need to set fadedness of any object, use currentAlpha. colorProperty.a = currentAlpha; When you want to change fadedness, only set desiredAlpha equal to 0 or 1…

Smoothing movement between any two particular values:

Beginner - need help with SmoothDamp

The problem is the choice of integer values for lanes. They can only either be lane 0, 1 or 2. They can't be in between round numbers. It needs to be a floating point value so that it can be between lanes. This type of question comes up so universally I have finally just made a sample package to demonstrate the basic concept. Read my first post above and see if you can correlate each part of the code to the steps indicated. Code located here: https://gist.github.com/kurtdekker/fb3c33ec6911a1…

You have currentQuantity and desiredQuantity.

• only set desiredQuantity
• the code always moves currentQuantity towards desiredQuantity
• read currentQuantity for the smoothed value

Works for floats, Vectors, Colors, Quaternions, anything continuous or lerp-able.
