LayerMask for RayCast
I have no idea why this isn't working.... if anyone can help me, I really appreciate it!
my script attached to my camera:
using UnityEngine;
using System.Collections;
public class placingObjectScript : MonoBehaviour
{
public bool treeSelected = true;
public GameObject[] tree;
void Update ()
{
if(Input.GetMouseButtonDown(0))
{
Ray ray;
RaycastHit hit;
ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if(Physics.Raycast(ray, out hit, 1 << 3))
{
if(treeSelected && hit.collider.tag == "placableGround")
{
Instantiate(tree[Random.Range (0, tree.Length)], hit.point, Quaternion.identity);
}
}
}
}
}
I have assigned everything to the default layer, and then the camera to Ingore Raycast. The camera has a collider, and without using layers, the trees will spawn on the camera's collider.
At the moment, when you click, nothing happens. It works when I get rid of the camera collider and the layer mask bit, but I really need a camera collider...

It seems there are no overloaded methods for Physics.Raycast(Ray, out hit, Layer$$anonymous$$ask) so I think your raycast have a lenght of 8 ^^
You're putting the layerMask value where maxDistance is supposed to go. It's also way easier to use a LayerMask popup to set the value in the inspector. And CompareTag is faster than comparing strings directly. See if this helps:
using UnityEngine;
using System.Collections;
public class placingObjectScript : MonoBehaviour
{
public LayerMask mask = -1;
public bool treeSelected = true;
public GameObject[] tree;
void Update ()
{
if(Input.GetMouseButtonDown(0))
{
Ray ray;
RaycastHit hit;
ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if(Physics.Raycast(ray, out hit, Mathf.Infinity, mask.value))
{
if(treeSelected && hit.collider.CompareTag("placableGround"))
{
Instantiate(tree[Random.Range (0, tree.Length)], hit.point, Quaternion.identity);
}
}
}
}
}
