説明

OnMouseDrag はマウスを押している間、毎フレーム呼び出されます。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Renderer rend;

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

    void OnMouseDrag()
    {
        rend.material.color -= Color.white * Time.deltaTime;
    }
}

この関数はレイヤーが「 Ignore Raycast 」のゲームオブジェクトでは呼び出されません。

This function is called on Colliders marked as Trigger if and only if Physics.queriesHitTriggers is true.

OnMouseDrag can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider.
