Using UnityEvent<bool> in the inspector?

I've used UnityEvents to create one of those nice little inspector interfaces , into which you can drag objects and choose methods, and so on. And in the UI components (e.g. Toggle), there are variants which can take bools or floats as parameters.

Combining the two has been fruitless so far. Having this in my code:

Code (csharp):

1.  
2.     public UnityEvent<bool> onChangeState;
3.  

...does not make anything appear in the inspector, unlike its non-generic, parameterless cousin.

How can I make that show up?

 

Try something like this.

You can't use the Generic UnityEvents directly.

Code (CSharp):

1. class MyEvent : UnityEvent<bool> {}
2. public MyEvent MyEvent;

 

Tried that. It compiles, but still nothing in the inspector.

 

Make your event class serializable using the [System.Serializable] attribute.
