MaterialPropertyBlock.SetColor

パラメーター

説明

color 型のプロパティーを設定します

プロパティーブロックを追加します。すでに同じ名前の color 型のプロパティーがある場合、上書きされます。

using UnityEngine;

// Draws 3 meshes with the same material but with different colors.
public class ExampleClass : MonoBehaviour
{
    public Mesh mesh;
    public Material material;
    private MaterialPropertyBlock block;

    void Start()
    {
        block = new MaterialPropertyBlock();
    }
    void Update()
    {
        // red mesh
        block.SetColor("_Color", Color.red);
        Graphics.DrawMesh(mesh, new Vector3(0, 0, 0), Quaternion.identity, material, 0, null, 0, block);

        // green mesh
        block.SetColor("_Color", Color.green);
        Graphics.DrawMesh(mesh, new Vector3(5, 0, 0), Quaternion.identity, material, 0, null, 0, block);

        // blue mesh
        block.SetColor("_Color", Color.blue);
        Graphics.DrawMesh(mesh, new Vector3(-5, 0, 0), Quaternion.identity, material, 0, null, 0, block);
    }
}

Function variant that takes nameID is faster. If you are changing properties with the same name repeatedly, use Shader.PropertyToID to get unique identifier for the name, and pass the identifier to SetColor.

using UnityEngine;

// Draws 3 meshes with the same material but with different colors.
public class ExampleClass : MonoBehaviour
{
    public Mesh mesh;
    public Material material;
    private MaterialPropertyBlock block;
    private int colorID;

    void Start()
    {
        block = new MaterialPropertyBlock();
        colorID = Shader.PropertyToID("_Color");
    }
    
    void Update()
    {
        // red mesh
        block.SetColor(colorID, Color.red);
        Graphics.DrawMesh(mesh, new Vector3(0, 0, 0), Quaternion.identity, material, 0, null, 0, block);

        // green mesh
        block.SetColor(colorID, Color.green);
        Graphics.DrawMesh(mesh, new Vector3(5, 0, 0), Quaternion.identity, material, 0, null, 0, block);

        // blue mesh
        block.SetColor(colorID, Color.blue);
        Graphics.DrawMesh(mesh, new Vector3(-5, 0, 0), Quaternion.identity, material, 0, null, 0, block);
    }
}
