Classroom Lab · Technical Producer · IAP Purchase Confirmation guide
Use a browser-playable Classroom Lab context to produce a state-machine and implementation handoff. Own transaction IDs, duplicate-submit guards, delivery ownership, reconciliation, persistence, and rollback evidence; treat the result as a workflow prototype, not proof that native billing is connected.
Create this game flow
Focused keyword and player case
Prototype a confirmation panel that keeps the item, exact Koin price, balance, Confirm, and Cancel visible together. The technical producer reviews consent, duplicate input, low balance, and safe cancellation and delivers a state-machine and implementation handoff. Acceptance means every transition has an owner, an observable receipt, an idempotent retry rule, and a safe recovery path after interruption.
Use the focused IAP Purchase Confirmation hub for an authentic screenshot, direct playable result, and the complete purchase-state checklist. Gameplay evidence supports placement testing; it does not prove a live transaction.
Turn the purchase into named states and transitions. Separate the player-facing prototype from identity, persistence, native billing, security, and refund work.
Design for the input, layout, interruption, and return behavior players expect from classroom game labs.
Use simulated Koin values and instructor review; do not collect student payment data.
Show one voluntary game item, its preview, full price in Koin, visible Koin balance, and ownership rule in a layout suited to classroom game labs.
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.
Make a player cancellation, too little Koin, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Map preview, confirmation, a cancelled choice, a Koin shortage, 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.
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. Treat Koin as a classroom game variable and do not request payment details, account credentials, or personal student information. The exercise is about interface states and responsible design.
Ask students to explain the item promise, free path, cancel behavior, failure recovery, and production boundary. Grade reasoning and playtest evidence rather than purchase completion.
Run the prototype on shared devices with accessible controls and privacy-safe displays. Native billing, identity, durable storage, refunds, platform approval, and real transactions remain outside the lab.
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.
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.
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.
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 classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
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 classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
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 classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
Choose the input and screen behavior for classroom game labs. State the platform limit beside the prototype brief.
Result: An honest scope
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
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
Map preview, confirmation, a player cancellation, too little Koin, pending, success, delivery, owned, and reload. Give every failure a safe next action.
Result: Technical producer focus
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
Create a non-production demonstration of purchase states 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: Use simulated Koin values and instructor review; do not collect student payment data.
Keep the item optional. Show its full price in Koin, visible Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
Own transaction IDs, duplicate-submit guards, delivery ownership, reconciliation, persistence, and rollback evidence. Coordinate adjacent work, but keep the page's acceptance artifact specific to this role.
Deliver a state-machine and implementation handoff that records consent, duplicate input, low balance, and safe cancellation, named owners, failure states, and the next production verification step.
No. Production release still requires authenticated records, security, refunds, platform compliance, monitoring, and support procedures.
