Is there a guide for setting up the client side part of local and push notifications for Lumberyard? The part that actually calls the Android and iOS apis?
The InAppPurchases gem is a good example of how to make calls from Lumberyard -> iOS or Android and back. Once you have that part sorted out, it’s a matter of doing the platform implementation (registering for PNs and so on) yourself. That’s true of anything platform specific, be it contacts / push notifs / iap / whatever. All you need to do is figure out how to make the “jump” from your C/C++ gem and into Obj-C and/or Java, and the rest is up to you.
(FWIW, that’s exactly what we did – looked at how the IAP gem interacted with the platform and then built out push notifs, auth, etc)
