Third Party Photon: How to get all health from players in master client?

I have a game where the master client is a player that controls all other players, so when the players select their ammo, the master client needs to know what ammo has been selected for all other players.

What call would do that for me?

 

You could use an RPC to send the MasterClient the selected ammo value.

Or you could make the selected ammo value a custom property and then all clients will be updated when the value changes. Also it will have the added benefit that should the MasterClient change the new MasterClient will already have the correct information.
