Trying to get a script's function to be called from dynamically instantiated objects.

I have a "Hype.cs" script that controls a text label on the screen, and a "Blip.cs" that controls the behavior of the instances of a certain prefab called Blip.

Blip.cs has this:

Code (csharp):

1.  
2.     void OnTriggerStay(Collider other)
3.     {
4.             if (Input.GetButtonDown("Fire1"))
5.             {
6.                 //Tell Hype.cs to fire function addHype(1)
7.             }
8.     }
9.  

My problem is that I can't simply give Blip.cs a Hype object and drag the text object into the Blip object's script through the editor, as every instance of the Blip object is instantiated dynamically from a prefab. So I simply don't know what to do. I was looking for some ideas from Global Variables (and couldn't understand how to use Singletons or the Toolbox for that at all) to Events and EventSystem (And got the feeling that it isn't what I want)

 

If I understand you correctly....

Code (csharp):

1. class Hype {
2.     void Fire(GameObject other) {
3.     }
4. }
5.  
6. class randomObject {
7.     void OnTriggerStay(Collider other) {
8.         if (Input.GetButtonDown("Fire1")) {
9.             //Tell Hype.cs to fire function addHype(1)
10.             GameObject myText = GetComponent<Text>();
11.             Hype.Fire(myText );   /// Not sure how to call the function, but the point is that you pass your relevant GameObject to it
12.         }
13.     }
14. }
15.  

That should be the gist of it.

 

If there's only one Hype object, you could mark it as a singleton. The cheap version is simply:

Code (csharp):

1. public class Hype() : MonoBehaviour {
2.     public static Hype instance;
3.  
4.     void Awake() {
5.         instance = this;
6.     }
7. }

And then in Blip, you do:

Code (csharp):

1. void OnTriggerStay(Collider other) {
2.         if (Input.GetButtonDown("Fire1")) {
3.            Hype.instance.addHype(1);
4.         }
5. }

There are other ways to do this, and arguably better ways to do this, but this will work for sure.

 

If you're instantiating the Blips from a prefab, you can simply get the Blip component from your new object:

Code (csharp):

1.  
2. GameObject newBlipObject = Instantiate(blipPrefab);
3. Blip newBlip = newBlipObject.GetComponent<Blip>();
4.  

Then, just assign to members of newBlip or call methods on it.
