Prototype the journey before Blueprints
For a technical producer, this purchase confirmation prototype should make every player action and result the player can inspect easy to evaluate. Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Map preview, confirmation, a player cancellation, not enough Koin, pending, success, delivery, owned, and reload. Give every failure a safe next action. Use the browser build to settle the offer moment, information order, and recovery behavior before assigning Unreal UI, gameplay state, service, and platform-commerce work.
Separate concept from provider setup
List ownership, persistence, online services, native commerce providers, refunds, security, and certification as independent tasks. This page does not configure an Unreal purchasing integration.
Create engine expected scenarios
Carry the exact player-visible paths into later Unreal testing: decline, insufficient Koin, pending, interrupted delivery, owned state, and reopen. Verify one result across UI and gameplay state.
Name every state and owner
Separate preview, confirmation, pending, success, delivery, owned, insufficient Koin, cancel, interrupted, and reopened states. Assign later production work for identity, persistence, native billing, security, refunds, policy, and monitoring.
Define idempotent recovery
Repeated confirmation, a slow response, navigation during delivery, and reopening must resolve to one result. Record which state is authoritative and how the player can safely retry without another grant or Koin deduction.
Turn the prototype into tickets
Capture the visible behavior first, then create implementation tasks with expected examples for each transition and platform boundary. Do not translate a working browser interaction into an unsupported claim that backend commerce is complete.
Repeat the complete choice
The confirmation should repeat the selected item, exact Koin amount, visible Koin balance, remaining balance, and ownership rule without introducing a different offer. Test that behavior using Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers from this page.
Separate confirm from cancel
Use distinct actions with clear labels and enough spacing for the target input method. Returning to the game should never spend Koin. Test that behavior using Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers from this page.
Prevent repeated confirmation
After confirmation, show a pending state and disable repeated input until the result is known. A slow response should not create duplicate grants. Test that behavior using Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers from this page.
