Vector3Constructor

描述

使用给定的 x、y、z 分量创建新向量。

//Attach this script to a GameObject.
//Attach a Rigidbody component to the GameObject (Click Add Component button in the Inspector window and go to Physics<Rigidbody)
//This script moves a GameObject upwards using a Vector3
using UnityEngine;

public class Vector3CtorExample : MonoBehaviour
{
    Vector3 myVector;
    Rigidbody m_Rigidbody;
    float m_Speed = 2.0f;

    void Start()
    {
        //Set the vector, which you use to move the RigidBody upwards straight away
        myVector = new Vector3(0.0f, 1.0f, 0.0f);
        //Fetch the RigidBody you attach to the GameObject
        m_Rigidbody = GetComponent<Rigidbody>();
    }

    void Update()
    {
        //Move the RigidBody upwards at the speed you define
        m_Rigidbody.velocity = myVector * m_Speed;
    }
}

描述

使用给定的 x、y 分量创建新向量，并将 z 设置为零。
