Technical producer focus
Turn the purchase into named states and transitions. Separate the player-facing prototype from identity, persistence, native billing, security, and refund work.

Technical Producer Guide to Koin Purchase Confirmation for Unreal Prototype Teams
Use a playable browser prototype to work through purchase confirmation for Unreal prototype teams. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
Define the Unreal prototype teams scope
Platform context
Design for the input, layout, interruption, and return behavior players expect from Unreal prototype teams.
Prototype boundary
SEELE does not claim to configure native Unreal commerce providers from this page.
Purchase Confirmation in practice
Starting state
Show one item the player may decline, its preview, precise Koin price, balance before spending, and ownership rule in a layout suited to Unreal prototype teams.
Main task
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Keep each change visible to the player rather than hiding it in technical state.
Recovery
Make cancelling the action, an insufficient balance, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Role decision
Map preview, confirmation, a player cancellation, too little Koin, pending, success, delivery, owned, and reload. Give every failure a safe next action. Use the prototype to resolve player-facing questions before creating platform integration tasks.
Solve the purchase confirmation details
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, Koin balance now, 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.
Prototype the player journey
1. Set the platform context
Choose the input and screen behavior for Unreal prototype teams. State the platform limit beside the prototype brief.
Result: An honest scope
2. Map purchase confirmation
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Describe the player action and visible response at each point.
Result: A clear purchase confirmation sequence
3. Add the Koin choice
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
4. Apply the technical producer lens
Map preview, confirmation, cancelling the action, an insufficient balance, pending, success, delivery, owned, and reload. Give every failure a safe next action.
Result: Technical producer focus
5. Test return and recovery
Interrupt delivery, repeat the input, and reload. The prototype should never grant twice or leave the player in an unexplained state. Repeat the test after interruption and reload.
Result: A stable prototype
Generate the Unreal prototype teams prototype
Prompt 1
Create a browser-playable commerce-flow reference for a technical producer. Focus the IAP prototype on show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Use a direct Koin item transaction with preview, exact price, confirmation, cancel, insufficient balance, success, delivery, and reload behavior. The technical producer must be able to name every state, owner, failure path, and expected check. Do not add subscriptions, payment-provider UI, revenue analytics, or native platform claims. State this boundary: SEELE does not claim to configure native Unreal commerce providers from this page.
Prompt 2
Keep the item optional. Show its precise Koin price, balance before spending, confirm, cancel, low-balance, success, visible delivery, and reload states.
Technical Producer test checklist
- The purchase confirmation sequence feels natural for Unreal prototype teams.
- The technical producer can make the intended decision from the playable result.
- The item, Koin price, and balance appear ahead of confirmation.
- Cancel, an insufficient balance, pending, success, and reload have different outcomes.
- The page states this boundary: SEELE does not claim to configure native Unreal commerce providers from this page.
- Interrupt delivery, repeat the input, and reload. The prototype should never grant twice or leave the player in an unexplained state.
Limits for Unreal prototype teams
- SEELE does not claim to configure native Unreal commerce providers from this page.
- This guide uses a direct Koin transaction for one optional game item. It does not create a subscription or recurring charge.
- The result is a playable browser prototype. Native billing, identity, durable entitlements, security, refunds, and store approval need separate implementation.
- SEELE does not provide payment analytics, tax tools, payout reports, or guaranteed revenue through this flow.
Frequently asked questions
What does purchase confirmation mean here?
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. The result is shown as a playable Koin flow.
Is this a subscription?
No. The player spends Koin directly on one named item or unlock.
What happens if the player cancels?
Return to the same game state without spending Koin or delivering the item.
What if the Koin balance is too low?
Explain the shortage, preserve progress, and do not deliver the item.
Does this include payment or revenue reports?
No. It covers the player-facing purchase experience, not financial reporting.
Is the prototype ready for a native store?
No. SEELE does not claim to configure native Unreal commerce providers from this page.
