Unity - 限制相机移动

Question

我有一个 2D 项目，我希望能够通过触摸向右和向后移动相机...我找到了一个教程，通过滑动移动相机所以它工作正常但我如何设置最大移动距离相机？

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TouchController : MonoBehaviour
{
float touchStart = 0f;
Vector3 cameraDestination;
public float cameraSpeed = 0.1f;
Camera m_MainCamera;
// Use this for initialization
void Start()
{
    cameraDestination = Camera.main.transform.position;
}
// Update is called once per frame
void Update()
{
    if (Input.GetMouseButtonDown(0))
    {
        touchStart = Input.mousePosition.x;
    }
    if (Input.GetMouseButtonUp(0))
    {
        float delta = Input.mousePosition.x - touchStart;
        if (delta < -50f)
        {
            cameraDestination = new Vector3(Camera.main.transform.position.x + 500,
                Camera.main.transform.position.y, Camera.main.transform.position.z);
            // move the camera right
        }
        else if (delta > 50f){
            cameraDestination = new Vector3(Camera.main.transform.position.x - 500,
                Camera.main.transform.position.y, Camera.main.transform.position.z);
            // move the camera left
        }
    }
    if (Vector3.Distance(Camera.main.transform.position, cameraDestination) > 0.1f)
    {
        if (Camera.main.transform.position.x > cameraDestination.x)
        {
            Camera.main.transform.position = new Vector3(Camera.main.transform.position.x - cameraSpeed,
                Camera.main.transform.position.y, Camera.main.transform.position.z);
        }
        else
        {
            Camera.main.transform.position = new Vector3(Camera.main.transform.position.x + cameraSpeed,
                Camera.main.transform.position.y, Camera.main.transform.position.z);
        }
    }
}

}

Answer 1

你的问题不清楚，但我假设你想为相机的位置设置一个限制。为此，您需要 2 个点 - 最小点（x = 相机允许的最小 X 值，y = 相机允许的最小 Y 值）和最大点（同上但代表上界）

Vector2 minPosition, maxPosition;

然后，每次移动相机时，请检查以下条件，然后再移动它：

if (cameraDestination.x < maxPosition.x && cameraDestination.x > minPosition.x) //Ensures the camera's X value is within the allowed range
if (cameraDestination.y < maxPosition.y && cameraDestination.y > minPosition.y) //Ensures the camera's Y value is within the allowed range
