Raycast using button
Hi.
I'm trying to make an Android FPS Game.
I'm know how to use Raycasting. But When I'm trying to cast using a Button(Made on the Canvas), it doesn't seems to work.
I'm making a script that opens when I press a button.
I'm sure that nothing is wrong, but dunno why it doesn't work.
Here is the script.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class OpenDoor : MonoBehaviour {
public Camera cam;
public Animator door;
bool isOpened;
// Use this for initialization
void Start ()
{
isOpened = false;
}
// Update is called once per frame
public void OnClick ()
{
if (isOpened = false) {
Ray ray = new Ray (cam.transform.position, cam.transform.forward);
RaycastHit hit;
if (Physics.Raycast (ray, out hit, 5.0f))
{
if (hit.collider.CompareTag ("WarehouseDoor"))
{
door.SetBool ("Open", true);
isOpened = true;
}
}
}
}
}
Have you tried to put simple Debug.Log and Debug.DrawRay inside your various conditions to check where is the exact problem?
Yep. It doesn't raycast. Should I use void Update and onbuttondown ins$$anonymous$$d of public void OnClick? I'm adding a photo. 
Are you sure the click is detected? Does the following code outputs something when you click on the button?
public void OnClick ()
{
Debug.Log( isOpened ) ;
if (isOpened == false)
{
// ....
}
}
I've just tested your script, works fine here. ($$anonymous$$ake sure your door is close enough to your camera, otherwise, the Ray won't hit)
The problem may come from here:
if (isOpened = false)
Should be :
if (isOpened == false)
Or
if (!isOpened)
Nope. Doesn't work. I already checked for all of my Animators and Cameras. Any Idea?
This is the correct source of the problem. Single equation character means the if will always fail.
if(isOpened = false) // always fails if(isOpened == false) // Fails only when isOpened is true
