坦克大战中摄像机的设置

效果图：

 

 

设置如下：

摄像机设置：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraFllow : MonoBehaviour {
    public GameObject tank1;
    public GameObject tank2;
    Vector3 offset;
    // Use this for initialization
    void Start () {
      offset=transform.position- (tank1.transform.position +tank2.transform.position)/2;//相机默认偏移量(相机看向坦克中心的向量)
    }
    
    // Update is called once per frame
    void Update () {

        if (tank1==null||tank2==null)
        {
            return;
        }
        transform.position = (tank1.transform.position + tank2.transform.position) / 2 + offset;//相机时刻跟踪中心位置

        float dis = Vector3.Distance(tank1.transform.position,tank2.transform.position);//两个坦克距离
        GetComponent<Camera>().orthographicSize = dis * 0.4f;//坦克距离有正交摄像机的Size成比例
        
    }
}
