描述

这是 MoveDirection 的 Up 状态。分配向上移动的功能。

使用 Up 状态,以可轻松识别的方式向上移动游戏对象 (0 , 1 , 0)。这种状态无需任何预定义功能。使用此状态之前,您应该先在代码中定义游戏对象要执行的操作。

//Attach this script to a GameObject with a Rigidbody component. Press the "Move Up" button in Game view to see it in action.

using UnityEngine; using UnityEngine.EventSystems;

public class Example : MonoBehaviour { Vector3 m_StartPosition, m_StartForce; Rigidbody m_Rigidbody; //Use Enum for easy switching between direction states MoveDirection m_MoveDirection;

//Use these Vectors for moving Rigidbody components Vector3 m_ResetVector; Vector3 m_UpVector; const float speed = 10.0f;

void Start() { //You get the Rigidbody component attached to the GameObject m_Rigidbody = GetComponent<Rigidbody>(); //This starts with the Rigidbody not moving in any direction at all m_MoveDirection = MoveDirection.None;

//These are the GameObject’s starting position and Rigidbody position m_StartPosition = transform.position; m_StartForce = m_Rigidbody.transform.position;

//This Vector is set to 1 in the y axis (for moving upwards) m_UpVector = Vector3.up; //This Vector is zeroed out for when the Rigidbody should not move m_ResetVector = Vector3.zero; }

void Update() { //This switches the direction depending on button presses switch (m_MoveDirection) { //The starting state which resets the object case MoveDirection.None: //Reset to the starting position of the GameObject and Rigidbody transform.position = m_StartPosition; m_Rigidbody.transform.position = m_StartForce; //This resets the velocity of the Rigidbody m_Rigidbody.velocity = m_ResetVector; break;

//This is for moving in an upwards direction case MoveDirection.Up: //Change the velocity so that the Rigidbody travels upwards m_Rigidbody.velocity = m_UpVector * speed; break; } }

void OnGUI() { //Press the reset Button to switch to no mode if (GUI.Button(new Rect(100, 0, 150, 30), "Reset")) { //Switch to start/reset case m_MoveDirection = MoveDirection.None; }

//Press the Up button to switch the Rigidbody direction to upwards if (GUI.Button(new Rect(100, 60, 150, 30), "Move Up")) { //Switch to Up Direction m_MoveDirection = MoveDirection.Up; } } }
