Subscribing to a function/method

Hi there,
I was under the impression I could subscribe to a function on another object script like this....

Code (csharp):

1.  
2. //object a
3. public void do(){}
4.  
5.  
6. //object b
7. objectA.do += do;
8.  
9.  

But I don't seem to be able to. Any ideas?

Thanks

 

You're looking for events and delegates.

Code (csharp):

1. // defines the "pattern" of the event
2. public delegate void SomeCallbackFunction(string parameterTheFunctionExpects);
3. // the event itself
4. public event SomeCallbackFunction myCallback;
5.  
6. //call the event (always null check it)
7. if (myCallback != null) {
8. myCallback("Foo");
9. }
10.  
11.  
12. //subscribe to the event
13. objectA.myCallback += myFunc;
14. void myFunc(string myParam) {
15. Debug.Log(myParam);
16. }
17.  

 

Code (csharp):

1. //object a
2. public Action SomethingHappened;
3. public void do()
4. {
5.     if (SomethingHappened != null) SomethingHappened();
6. }
7.  
8. //object b
9. void Start()
10. {
11.     objectA.SomethingHappened += DoWhenTriggered;
12. }
13.  
14. public void DoWhenTriggered()
15. {
16.  
17. }

 

Sweet!
