Instructions
- Add to XCode: Add SPM (Swift Package Manager) dependency
- Add Rust dependency
- Setup Plugin
1. Add to XCode
-
Add
StoreKit
framework: -
Go to
File
->Add Package Dependencies
and pastehttps://github.com/rustunit/bevy_ios_iap.git
into the search bar on the top right: -
Don't forget to configure your purchases like for any other iOS app, this guide will not focus on that, as it is the same no matter what engine you use. this guide focuses on setting things up in a bevy project.
Note:
The rust crate used must be exactly the same version as the Swift Package (for binary compatibility reasons).
I suggest using a specific version (like 0.2.0
in the screenshot) to make sure to always use binary matching versions!
2. Add Rust dependency
cargo add bevy_ios_iap
or
# always pin to the same exact version you also of the Swift package
bevy_ios_iap = { version = "=0.2.1" }
3. Setup Plugin
Initialize Bevy Plugin:
// request initialisation right on startup
app.add_plugins(IosIapPlugin::new(true));
fn bevy_system() {
// If you set the plugin to manual init, this will register the
// TranscactionObserver to listen to updates to any Transactions and trigger
// `IosIapEvents::Transaction` accordingly.
// Note: this will require the user to be logged in into their apple-id and popup a login dialog if not
bevy_ios_iap::init();
// request product details, product IDs have to be explicitly provided
// this will lead to a response: `IosIapEvents::Products`
bevy_ios_iap::get_products(vec!["com.rustunit.zoolitaire.levelunlock".into()]);
// trigger a product purchase for a specific product ID
// this will lead to a response: `IosIapEvents::Purchase`
bevy_ios_iap::purchase("com.rustunit.zoolitaire.levelunlock".into());
// request to restore active subscriptions and non-consumables
// this will lead to a response: `IosIapEvents::CurrentEntitlements`
bevy_ios_iap::current_entitlements();
// marks a transaction as finished after the product was provided to the customer.
// if this is not called a transaction will keep being triggered automatically on
// app start as iOS wants us to be sure we granted the user the purchased good.
// this will lead to a response: `IosIapEvents::TransactionFinished`
bevy_ios_iap::finish_transaction(42);
}
Process Response Events from iOS back to us in Rust:
fn process_iap_events(
mut events: EventReader<IosIapEvents>,
) {
for e in events.read() {
match e {
IosIapEvents::Products(_) => todo!(),
IosIapEvents::Purchase(_) => todo!(),
IosIapEvents::Transaction(_) => todo!(),
IosIapEvents::TransactionFinished(_) => todo!(),
IosIapEvents::AllTransactions(_) => todo!(),
IosIapEvents::CurrentEntitlements(_) => todo!(),
}
}
}
