WebGL · Technical Producer · IAP Purchase Recovery guide
Use a browser-playable WebGL 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 an interrupted 60 Koin unlock reconciled after reload without charging or granting twice. The technical producer reviews pending state, transaction reconciliation, restore, and support evidence 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 Recovery 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 WebGL games.
WebGL rendering and commerce state need separate failure testing.
Show one item that remains optional, its preview, precise Koin price, available Koin balance, and ownership rule in a layout suited to WebGL games.
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. 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 recovery prototype should make every player action and result the player can inspect easy to evaluate. Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Map preview, confirmation, a player cancellation, not enough Koin, pending, success, delivery, owned, and reload. Give every failure a safe next action. Open and close the interface during GPU-heavy scenes, then monitor input, frame pacing, and canvas recovery. A commerce overlay should not leave the game loop paused or controls captured unexpectedly.
Make the selected item and outcome visible in both interface and gameplay context. Handle focus loss, pointer lock, fullscreen transitions, and a resized canvas around confirmation and return.
Simulate refresh, background suspension, and a lost rendering context. The player-facing purchase result should reconcile separately from graphics recovery and must never duplicate an item.
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.
If delivery is interrupted, explain whether the result is pending, safe to retry, or already complete. Do not show both failure and success. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Repeated clicks and reloads should resolve to one purchase result. The player must never receive duplicate items or lose Koin twice. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Cancelling the action, an insufficient balance, and recoverable errors should preserve progress and offer a clear return or retry action. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Choose the input and screen behavior for WebGL games. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Describe the player action and visible response at each point.
Result: A clear purchase recovery 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 GPU-accelerated browser canvas for a technical producer. Focus the IAP prototype on handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. 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: WebGL rendering and commerce state need separate failure testing.
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 pending state, transaction reconciliation, restore, and support evidence, 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.
