The script doesn't to space being pressed anymore, AND, can't manage alpha of canvas.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3.  
4.  
5. class CameraFollow : MonoBehaviour {
6.     private Vector3 currentPosition;
7.     public GameObject Player;
8.     public Transform ZoomOutTo;
9.     // public GUIManager GUIToggler;
10.     float zDistance;
11.  
12.     public float speed = 1.0f;
13.  
14.     public Canvas THECanvas;
15.  
16.     private float zoomOutStartTime;
17.     private float ABDistance;
18.  
19.     public float zoomedIn = 1.73f;
20.     public float zoomedOut = 4.5f;
21.  
22.     public bool zoomed = false;
23.    
24.     void Start() {
25.         currentPosition = transform.position;
26.         zDistance = currentPosition.z - Player.transform.position.z;
27.  
28.         ABDistance = Vector3.Distance(transform.position, ZoomOutTo.position);
29.  
30.         camera.orthographic = true;
31.     }
32.    
33.     void Update() {
34.         Vector3 toPosition = new Vector3(Player.transform.position.x, Player.transform.position.y, Player.transform.position.z + zDistance);
35.         transform.position = toPosition;
36.  
37.         if (Input.GetKeyDown(KeyCode.Space)) { zoomed = !zoomed; }
38.  
39.         if (zoomed) {
40.             THECanvas.GetComponent<UnityEngine.UI.Image>().CrossFadeAlpha(0f, 1f, false);
41.             camera.orthographicSize = Mathf.Lerp(camera.orthographicSize, 4.5f, Time.deltaTime);
42.             if (camera.orthographicSize >= 4) { Time.timeScale = 0.0001f; }
43.         }
44.         else {
45.             THECanvas.GetComponent<UnityEngine.UI.Text>().CrossFadeAlpha(1f, 1f, false);
46.             camera.orthographicSize = Mathf.Lerp(camera.orthographicSize, 1.73f, Time.deltaTime);
47.             Time.timeScale = 1;
48.         }
49.     }
50. }

Pressing Space doesn't give any effect, while it did before. AND, I can't manage Canvas to disappear because of these two errors.

Same error on line 40.

 

Have you dragged the object you want into the Canvas field in the editor ? Either do that or Find the object and set the reference in code in your Start function.

 

Did I do it wrong? Sure "Zoom Out To", is also empty. But it's not line the Unity is referring to, Unity is referring to lines where I use THECanvas as an object, he can't handle it. Except "THECanvas" script is dependant right?

 

If the Canvas is set there, then it must be the GetComponent.

I haven't used the new unity gui yet but it looks like the elements you are referencing will be children of the canvas.

Either use GetComponentInChildren<>() or more sensibly store a reference to your image and text game objects and access them using that. If you have more than one image or text child in your GUI (which is likely) you will want to be able to reference them all individually.

 

So it becomes:

THECanvas.GetComponentsInChildren<UnityEngine.UI.Image>().CrossFadeColor(Color.black, 2.0f, false);

 

That should work, but only if you have one Image on your canvas. Not ideal.

It's better if you store a reference to your image like you do with the canvas.

Then reference the image directly.

 

THECanvas.GetComponentsInChildren<UnityEngine.UI.Image>().CrossFadeColor(Color.black, 2.0f, false);
That should work, but only if you have one Image on your canvas. Not ideal.

The "CrossFadeColor" is red, that means an error. I colored the text as my editor shows me. It wasn't solution I came up with.

Error being:
Assets/Scripts/HPThing.cs(17,60): error CS1061: Type `UnityEngine.UI.Image[]' does not contain a definition for `CrossFadeAlpha' and no extension method `CrossFadeAlpha' of type `UnityEngine.UI.Image[]' could be found (are you missing a using directive or an assembly reference?)

I also changed from: using UnityEditor.UI; to using UnityEngine.UI;

 

ok your using GetComponents plural, that returns an array, I didnt spot that.

http://docs.unity3d.com/ScriptReference/Component.GetComponentsInChildren.html

 

This is exactly what I had, I just copied the line from link you provided, changed it to my use, but it´s exactly same code that is now in commented chain.

 

Look at the documentation for the two different functions, the one I suggested

http://docs.unity3d.com/ScriptReference/Component.GetComponentInChildren.html

and the one you are using that I linked you above.

The one you are using is returning an array, which means you have to loop through the returned objects.

How do I even get data from a

THECanvas.GetComponentsInChildren<Image>().CrossFadeColor(Color.black, 2.0f, false);

This isn't a variable, this is calling a function. How do I get array from "Execute this".?
