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; } }
使用给定的 x、y 分量创建新向量,并将 z
设置为零。
