如果我按下某个键,我怎么才能在相机之间切换?
问题描述:
好了,所以我有2个摄像头设置在我的层次在Unity:如果我按下某个键,我怎么才能在相机之间切换?
我想知道,当在游戏中,我怎么能这两款相机之间切换,当某个键被按下?我知道我可能需要为此做一个脚本,只是不知道我该怎么做。

您可以添加多台摄像机
using UnityEngine;
using System.Collections;
public class CameraController : MonoBehaviour {
// Use this for initialization
public Camera[] cameras;
private int currentCameraIndex;
// Use this for initialization
void Start() {
currentCameraIndex = 0;
//Turn all cameras off, except the first default one
for (int i=1; i<cameras.Length; i++)
{
cameras[i].gameObject.SetActive(false);
}
//If any cameras were added to the controller, enable the first one
if (cameras.Length>0)
{
cameras [0].gameObject.SetActive (true);
Debug.Log ("Camera with name: " + cameras [0].GetComponent<Camera>().name + ", is now enabled");
}
}
// Update is called once per frame
void Update() {
//If the c button is pressed, switch to the next camera
//Set the camera at the current index to inactive, and set the next one in the array to active
//When we reach the end of the camera array, move back to the beginning or the array.
}
public void Change()
{
currentCameraIndex ++;
Debug.Log ("C button has been pressed. Switching to the next camera");
if (currentCameraIndex < cameras.Length)
{
cameras[currentCameraIndex-1].gameObject.SetActive(false);
cameras[currentCameraIndex].gameObject.SetActive(true);
Debug.Log ("Camera with name: " + cameras [currentCameraIndex].GetComponent<Camera>().name + ", is now enabled");
}
else
{
cameras[currentCameraIndex-1].gameObject.SetActive(false);
currentCameraIndex = 0;
cameras[currentCameraIndex].gameObject.SetActive(true);
Debug.Log ("Camera with name: " + cameras [currentCameraIndex].GetComponent<Camera>().name + ", is now enabled");
}
}
}

非常基本的问题,你应该去一些C#教程。
无论如何,这是可以做到的。把这个更新方法:
if (Input.GetKeyDown("space"))
{
//don't forget to set one as active either in the Start() method
//or deactivate 1 camera in the Editor before playing
if (Camera1.active == true)
{
Camera1.SetActive(false);
Camera2.SetActive(true);
}
else
{
Camera1.SetActive(true);
Camera2.SetActive(false);
}
}

通过简单地等待某人为您写脚本,您不会学到任何东西。你需要有一些东西。至少,一个简单的if语句从键盘读取,然后用另一个简单的代码行来改变主摄像机。只是谷歌“统一改变主摄像头” – Programmer
