Top down camera lock
i have tried the solution in: http://answers.unity3d.com/questions/473917/how-to-prevent-camera-from-moving-through-meshes.html
my clip camera to the target so far is:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CameraClip : MonoBehaviour
{
[SerializeField]
Transform target;
float yoffset = 20;
float xoffset = -10;
float zoffset = -10;
void LateUpdate()
{
transform.position = new Vector3(target.position.x + xoffset, target.position.y + yoffset, target.position.z + zoffset);
}
}
However, even though i have a collider and this clip on a parent to the main camera...the parent still goes right through collisions...the solution at the bottom of that link did not work. what is i missing to stop the camera from going through walls? I've uploaded a pic to show the problem 
I have figured out a way to lock it myself:
public float lockxmin;
public float lockzmin;
[SerializeField]
float lockxmax;
[SerializeField]
float lockzmax;
if (transform.position.x < lockxmin || transform.position.x > lockxmax)
{
var temp = transform.position;
temp.x = Mathf.Clamp(temp.x, lockxmin, lockxmax);
transform.position = temp;
}
if (transform.position.z < lockzmin || transform.position.z > lockzmax)
{
var temp = transform.position;
temp.z = Mathf.Clamp(temp.z, lockzmin, lockzmax);
transform.position = temp;
}
This would restrict the camera to stay within a region specified by your $$anonymous$$ and max values not actually prevent the clipping issue of camera by it passing through other objects.
Right it essentially defines a map size which is all that's needed for the edges of terrain. The #1 issue is i can't clip terrain so I've been trying to find a way around that issue. That is why i had the question the way it is...Also the other answer only works for a 3rd person camera which is not what I'm doing either. It's top down like the title says. I tried to get it to work with my setup but can't do it. No matter what i do the clipping wouldn't work right.
It is passing through because you are setting the position directly via transform.position which will move the gameobject to that position ignoring the collisions. In Standard Assets there is a script called ProtectCameraFromWallClip to prevent wall clipping of camera which you can use.
Although i found that CS file it is not that good on performance because it uses raycasting. However it is still an answer technically :)
