Simple Camera Switch Using C#
Hello, I'm new to the land of Unity and I'm trying to muddle my way through. I'm probably having issues due to inexperience using Unity and C#.
In very simple scene, I'm trying to make 2 camera's switch when a key is pressed on the board (C). Is there a simple method to achieve this using enabled = true?
Other notes that could be of use:
I have followed other vid tuts without success. :-( I have nested 2 camera's in a a Empty Game Object... do I need to do this?
I'm a newb.
Thanks for you help.
The End Script - -
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class CameraSwitch : $$anonymous$$onoBehaviour {
public Camera camera1;
public Camera camera2;
private void Awake ()
{
camera2.enabled = false;
}
public void SwitchCam ()
{
camera1.enabled = !camera1.enabled;
camera2.enabled = !camera2.enabled;
}
void Update()
{
if (Input.Get$$anonymous$$eyDown ($$anonymous$$eyCode.C))
{
Debug.Log ("C key was pressed");
SwitchCam ();
}
}
}
You can group your cameras, but don't have to.
Regarding the switch, you want to make sure you activate one and not the other. Something in the like :
public Camera camOne;
public Camera camTwo;
private void Awake ()
{
camTwo.enabled = false;
}
public void SwitchCam ()
{
camOne.enabled = !camOne.enabled;
camTwo.enabled = !camTwo.enabled;
}
This is one of many ways to do it.
Thanks UnityCoach. How would I go about making this work on a keybaord press? For example if I pressed "C" ?
if (Input.Get$$anonymous$$eyDown("C"))
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class CameraSwitch : $$anonymous$$onoBehaviour {
public Camera camera1;
public Camera camera2;
private void Awake ()
{
camera2.enabled = false;
}
public void SwitchCam ()
{
camera1.enabled = !camera1.enabled;
camera2.enabled = !camera2.enabled;
}
}
Et voilà !
void Update ()
{
if (Input.Get$$anonymous$$eyDown("C"))
SwitchCam ();
}
Thanks UC... although it has spat back this error...
"ArgumentException: Input $$anonymous$$ey named: C is unknown UnityEngine.Input.Get$$anonymous$$eyDown (System.String name) (at /Users/builduser/buildslave/unity/build/artifacts/generated/common/runtime/InputBindings.gen.cs:425) CameraSwitch.Update () (at Assets/CameraSwitch.cs:24)"
Is there something that I have failed to add in the editor?
Thanks!
Morning... Managed to stop it spitting back errors but the camera transitions doesn't work. Another thing to note is that the object in my scene is flash/blinking rapidly. Any clues?
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class CameraSwitch : MonoBehaviour {
public Camera camera1;
public Camera camera2;
private void Awake ()
{
camera2.enabled = false;
}
public void SwitchCam ()
{
camera1.enabled = !camera1.enabled;
camera2.enabled = !camera2.enabled;
}
void Update() {
if (Input.GetKeyDown(KeyCode.C))
print("C key was pressed");
SwitchCam ();
}
}
Thanks,
Ah, if you want to add more than one line of code to an if statement, you need opening and closing brackets.
void Update()
{
if (Input.Get$$anonymous$$eyDown ($$anonymous$$eyCode.C))
{
Debug.Log ("C key was pressed");
SwitchCam ();
}
}
Hello Unity Coach, thank you for your help! I have also tested this on my mac and it works. I might add some comments to this at some stage. Cheers Thank you!

Well I tried this code as I wish for more than one camera in my game I want lots as I want to be able to see from both friendlies and enemies but all I keep getting when I run this code is this
