MonoBehaviour.Update()

説明

Update は MonoBehaviour が有効の場合に、毎フレーム呼び出されます

Update is the most commonly used function to implement any kind of game script. Not every MonoBehaviour script needs Update.

// Moves the object forward 1 meter a second

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Update()
    {
        transform.Translate(0, 0, Time.deltaTime * 1);
    }
}

In order to get the elapsed time since last call to Update, use Time.deltaTime. This function is only called if the Behaviour is enabled. Override this function in order to provide your component's functionality.
