The best way to call a function on one directive from another directive

[Garey Mills]

I have a directive that models and displays a game board. When a piece is captured on the board, I want that to be recorded and displayed in another widget, which will probably have to be a directive) on the same page as the board directive. I cannot see the way to call a function on the recording directive. I have read the developer's guide for directives carefully, but it seems to be very complex for what seems a simple action. How do you, from a directive, call a function on another directive that increments or decrements a variable on the called directive?

Any help would be appreciated.

Hey,

The idea is fine but this is done via a service or a store or a global state. Both the main page and the directive would be listening to events, data changes in the service...

Hope this helps

Thanks. I'll look at services. Part of the problem is the recorder has to show the number of pieces captured, and be available for a drag and drop of the pieces back on to the board.

The brain is not where you think.

I don't see how to use services, and I don't have any information about stores or global states. If possible, would you point me to any information?
