How to activate children in heirachry from a script not attached to that gameobject?

Hello,

I have tried this code....

child.GameObject.setActive (true);

or something like it. But I know whatever it was is correct for usual circumstances.

I have just removed the code as it doesn't work for the circumstance I wish it to work for. It just creates compiler errors (I apologise for not uploading them but I didn't see the point as I first need to adjust this code to somehow access hierarchy components when not attached to them through a pre-existing script). I am trying to activate a child named "Button1" in a gameobject called "GameObject2". How can I do this from a script which IS NOT attached to either of these items as it is attached to another button that will run when clicked?

Thanks - Any help would be much appreciated!

 

gameObject

Spelling is important.

 

@zombiegorilla can you help? like I mean respond with code please.

 

Like I said, gameObject not GameObject.

 

This is a very simple thing, and @zombiegorilla it's not that, do you even understand what he needs ?

So you want to activate the child of some object, but from a script that is attached to a whole diffrent object which is neither of theese two...

This can't be more simple, here's a C#:

public GameObject theTargetChild;


And then add this code to activate it:

theTargetChild.setActive(True);


EDIT:
Sorry, and then back at unity screen, take a look at your script, and you should see a new value added called "The Target Child". Now drag and drop your child object into that value, and you should be good to go.

EDIT 2: If you're not using C#, this won't work... And really can't help you if you're scripting in javascript, i haven't used that in a long time and i'm not really sure there.


Aaand, if you need a full code, a whole piece of code then tell me what you exactly want to happen, maybe a button press will activate that child or something idk, but i think this should help,



EDIT 3: Maaybe this could work in javascript, i'm not sure, you can try it:

var theTargetChild: GameObject;

And then to activate it:

theTargetChild.setActive(True);


And then back at unity do the same i said before

 

Yes, because he has already been given the answer, this is a double post.

"child" is a Transform, the result of a looping through an array of Transform. GameObject is a class, gameObject is a member of Transform that returns the GameObject the Transform is attached to. .SetActive is a method of GameObject.
So:
child.gameObject.SetActive(bool) sets the active state of the GameObject "child" is attached to.
child.GameObject.SetActive(bool) is gibberish and will throw an error.

 

I did as you instructed @RickyX but I got the following error.



Here is my code

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4. public class CheckAnsL1 : MonoBehaviour
5. {
6.    
7.     public InputField iField;
8.     string myName;
9.     string myText;
10.     public int score = 0;
11.  
12.     public GameObject theTargetChild;
13.    
14.     GameObject myTextgameObject; // gameObject in Hierarchy
15.     Text ourComponent;           // Our refference to text component
16.    
17.     void Start()
18.     {
19.         if (PlayerPrefs.HasKey("Score") == true)
20.         {
21.             score = PlayerPrefs.GetInt("Score");
22.         }
23.        
24.         // Find gameObject with name "MyText"
25.         myTextgameObject = GameObject.Find("MyText");
26.         // Get component Text from that gameObject
27.         ourComponent = myTextgameObject.GetComponent<Text>();
28.     }
29.    
30.     public void MyFunction()
31.     {
32.         Debug.Log(iField.text);
33.         myName = iField.text;
34.         if (myName == "city")
35.         {
36.             score++;
37.             Debug.Log("Correct! The word 'city' is correct!");
38.             Debug.Log("Your score is now:");
39.             Debug.Log(score);
40.             PlayerPrefs.SetInt("Score", score);
41.         }
42.         else
43.         {
44.             score--;
45.             Debug.Log("Incorrect! The answer was 'city'.");
46.             Debug.Log("Your score is now:");
47.             Debug.Log(score);
48.             PlayerPrefs.SetInt("Score", score);
49.         }
50.  
51.         theTargetChild.setActive(True);
52.     }
53.    
54.     void Update () {
55.         ourComponent.text = score.ToString();
56.     }
57. }

And here is a screenshot of the hierarchy...



Please tell me what I am doing wrong

 

@zombiegorilla Can you find the issue in the post above by me? I have provided the code, an image of my hierarchy and even the compiler errors.

 

@zombiegorilla & @RickyX thanks for your help! I fixed all the errors myself! So proud! I thank you for your help so far and will contact you if needed in the future! Thanks again!

 

Sorry pal' I wasn't around, i'd help. Glad you fixed it though !

 

Sorry didn't know about that post...

 

Hello,

I have the code below which works perfectly. I would like to somehow (in a new scene) pull the score variable from the previous code and display it in a UI text. I would also like the new script in the new scene to run automatically without any triggers?

Any help would be much appreciated!

Here is my code...

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4. public class CheckAnsL8 : MonoBehaviour
5. {
6.    
7.     public InputField iField;
8.     string myName;
9.     string myText;
10.     public int score = 0;
11.    
12.     public Text Status;
13.    
14.     GameObject myTextgameObject; // gameObject in Hierarchy
15.     Text ourComponent;           // Our refference to text component
16.    
17.     void Start()
18.     {
19.         if (PlayerPrefs.HasKey("Score") == true)
20.         {
21.             score = PlayerPrefs.GetInt("Score");
22.         }
23.        
24.         // Find gameObject with name "MyText"
25.         myTextgameObject = GameObject.Find("MyText");
26.         // Get component Text from that gameObject
27.         ourComponent = myTextgameObject.GetComponent<Text>();
28.     }
29.    
30.     public void MyFunction()
31.     {
32.         Debug.Log(iField.text);
33.         myName = iField.text;
34.         if (myName == "castle")
35.         {
36.             score++;
37.             Debug.Log("Correct! The word 'castle' is correct!");
38.             Debug.Log("Your score is now:");
39.             Debug.Log(score);
40.             PlayerPrefs.SetInt("Score", score);
41.             Status.text = "Correct!";
42.             Status.color = Color.green;
43.         }
44.         else
45.         {
46.             score--;
47.             Debug.Log("Incorrect! The answer was 'castle'.");
48.             Debug.Log("Your score is now:");
49.             Debug.Log(score);
50.             PlayerPrefs.SetInt("Score", score);
51.             Status.text = "Incorrect!";
52.             Status.color = Color.red;
53.         }
54.        
55.         GameObject theTargetChild = GameObject.Find("theTargetChild");
56.         foreach (Transform child in theTargetChild.transform)
57.         {
58.             child.gameObject.SetActive(true);
59.         }
60.     }
61.    
62.     void Update () {
63.         ourComponent.text = score.ToString();
64.     }
65. }

 

FIXED IT! YAY
