설명

Represents a Gradient used for animating colors.

Gradients allow animating or interpolating colors by having several "color keys" and "alpha keys". Color keys and alpha keys are separate, and each key has a time specified for it, ranging from 0.0 (0%) to 1.0 (100%). Note that the alpha and colors keys will be automatically sorted by time value and that it is ensured to always have a minimum of 2 color keys and 2 alpha keys.

How the colors are interpolated between the keys is controlled by GradientMode.

Public Gradient variables used in scripts automatically display the gradient editor in the inspector window. GradientUsageAttribute allows specifying whether the gradient colors should be high dynamic range for editing.

using UnityEngine;

public class ExampleScript : MonoBehaviour { void Start() { var gradient = new Gradient();

// Blend color from red at 0% to blue at 100% var colors = new GradientColorKey[2]; colors[0] = new GradientColorKey(Color.red, 0.0f); colors[1] = new GradientColorKey(Color.blue, 1.0f);

// Blend alpha from opaque at 0% to transparent at 100% var alphas = new GradientAlphaKey[2]; alphas[0] = new GradientAlphaKey(1.0f, 0.0f); alphas[1] = new GradientAlphaKey(0.0f, 1.0f);

gradient.SetKeys(colors, alphas);

// What's the color at the relative time 0.25 (25%) ? Debug.Log(gradient.Evaluate(0.25f)); } }
