阻止相机移动通过物体 [英] Stop camera from moving through objects

问题描述

关于这个主题有很多问题，但是我找不到适合我的问题.

There is a lot of questions on this theme but i couldn't find one that is fitting me.

我有一个如下所示的摄像机移动脚本:

I have camera movement script which looks like this:

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

[AddComponentMenu("Camera-Control/Smooth Mouse Look")]
public class SmoothMouseLook : NetworkBehaviour
{
    [Header("Character camera.")]
    private Camera myCamera;
    [Header("Location where camera will always be looking at.")]
    public Transform characterHead;

    [Header("How fast will camera zoom work")]
    public float cameraScrollSensitivity = 2f;

    [Header("Default position of camera")]
    public Vector3 cameraPos = new Vector3(0, 2, 0);

    public Vector3 minPos = new Vector3(-4, -4, -5);
    public Vector3 maxPos = new Vector3(4, 4, -1);

    [Header("How fast will camera move on Y axis")]
    public float cameraSensitivityY = 0.8f;
    [Header("How fast will camera move on X axis")]
    public float cameraSensitivityX = 0.8f;

    public enum InvertX { False = 0, True = 1 }
    public enum InvertY { False = 0, True = 1 }

    public InvertX invertX = InvertX.False;
    public InvertY invertY = InvertY.False;

    void Start()
    {
        if (!isLocalPlayer)
            return;

        Camera.main.gameObject.transform.parent = this.transform;
        Camera.main.gameObject.transform.localPosition = cameraPos;
        myCamera = Camera.main;

        myCamera.transform.LookAt(characterHead);

    }
    void Update()
    {
        if (!isLocalPlayer)
            return;

        Vector3 currPos = myCamera.transform.localPosition;

        currPos.z += Input.GetAxis("Mouse ScrollWheel") * cameraScrollSensitivity;
        if (currPos.z > maxPos.z)
            currPos.z = maxPos.z;
        if (currPos.z < minPos.z)
            currPos.z = minPos.z;

        if (Input.GetMouseButton(2))
        {

            if(invertY == 0)
                currPos.y -= Input.GetAxis("Mouse Y") * cameraSensitivityY / 10;
            else
                currPos.y += Input.GetAxis("Mouse Y") * cameraSensitivityY / 10;


            if (invertX == 0)
                currPos.x += Input.GetAxis("Mouse X") * cameraSensitivityX / 10;
            else
                currPos.x -= Input.GetAxis("Mouse X") * cameraSensitivityX / 10;


            if (currPos.y > maxPos.y)
                currPos.y = maxPos.y;
            if (currPos.y < minPos.y)
                currPos.y = minPos.y;
            if (currPos.x > maxPos.x)
                currPos.x = maxPos.x;
            if (currPos.x < minPos.x)
                currPos.x = minPos.x;
        }

        myCamera.transform.localPosition = currPos;

        myCamera.transform.LookAt(characterHead);
    }
}

此脚本附加在角色上，相机是孩子.

This script is attached to character and camera is it's child.

正如标题所述，问题在于相机可以穿过网格(物体和地形).

Just as title says, problem is that camera can go through mesh (objects and terrain).

我尝试将剔除蒙版"设置为0.01和1(默认值为0.3)，但没有任何反应.

I tried setting Culling mask to 0.01 and 1 (default is 0.3) but nothing happens.

我尝试添加对撞机，当我将摄像机推到它撞到的地面时，它可以工作，但不会让摄像机掉下来，但是会抬起角色:/

I tried adding collider which works BUT when i push camera to the ground it collides, doesn't let camera down but it lift character up :/

我唯一的想法是使用raycast对其进行编码，但是由于我不熟悉这一切，因此我想检查是否还有其他方法(例如使用对撞机但不抬起字符)，因为这会花费很多时间我用raycast弄清楚了.

Only idea i have is coding it with raycast but since i am new to all this i wanted to check if there is any other way of doing it (like with collider but do not lift character) because it will take a lot of my time figuring it out with raycast.

推荐答案

您可以尝试执行此操作吗?如果您不希望像虚幻引擎中的相机那样穿过网格，则可以这样做

Could you try doing this things . If you mean not pass through meshes like the camera in Unreal Engine you can do it something like this

1. 选择相机，进入检查器并将近裁剪平面设置为0.1
2. 创建一个空的游戏对象.给一个空的盒子对撞机，并将其设置为相机的确切位置.最后，将空对象设置为Camera的父对象.现在，当您将其移为空时，它将移动相机，并且不会穿过墙壁.
