Material.Lerp

Description

在两个材质之间对属性进行插值。

Makes all color and float values of a material be interpolated from start to end, based on t.
When t is 0, all values are taken from start.
When t is 1, all values are taken from end.

通常希望在其间进行插值的材质除了颜色 和浮点值之外都相同（使用相同着色器和纹理）。随后可使用 Lerp 在它们之间进行混合。

public class Example : MonoBehaviour
{
    // Blends between two materials

    Material material1;
    Material material2;
    float duration = 2.0f;
    Renderer rend;

    void Start()
    {
        rend = GetComponent<Renderer> ();

        // At start, use the first material
        rend.material = material1;
    }

    void Update()
    {
        // ping-pong between the materials over the duration
        float lerp = Mathf.PingPong(Time.time, duration) / duration;
        rend.material.Lerp(material1, material2, lerp);
    }
