Godot · Technical Producer · IAP Inventory Delivery guide
Use a browser-playable Godot 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 delivered item that moves from pending to owned exactly once and appears in the correct inventory slot. The technical producer reviews idempotent delivery, quantity, ownership, and visible inventory state 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 Inventory Delivery 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 Godot prototype teams.
A browser prototype does not install Godot billing plugins or export store-ready binaries.
Show one item the player may decline, its preview, precise Koin price, balance before spending, and ownership rule in a layout suited to Godot prototype teams.
Write how to connect successful purchase to a visible owned or quantity state. Keep each change visible to the player rather than hiding it in technical state.
Make cancelling the action, an insufficient balance, pending, interrupted delivery, and reload visually distinct, with a safe next action.
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.
For a technical producer, this inventory delivery prototype should make every player action and result shown in the game easy to evaluate. Write how to connect successful purchase to a visible owned or quantity state. Map preview, confirmation, a cancelled choice, a Koin shortage, pending, success, delivery, owned, and reload. Give every failure a safe next action. Describe screens, signals, states, and outcomes without tying the concept to a billing plugin. This lets a Godot team choose architecture after the player journey has been tested.
Browser behavior does not install store plugins, create native entitlements, or export approved binaries. Assign persistence, identity, platform APIs, security, refunds, and export testing separately.
Once implemented, compare the same item definition and recovery paths against the prototype. Check scene changes, saved ownership, repeated input, and return from suspension without double delivery.
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.
A success message is not delivery. Place the cosmetic, consumable, unlock, or upgrade in the screen where the player expects to use it. Test that behavior using Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
Use owned, equipped, unlocked, or remaining quantity as appropriate. The state should match the promise made on the offer card. Test that behavior using Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
Reload the prototype and return to inventory. The item should remain visible without subtracting Koin or granting a second copy. Test that behavior using Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
Choose the input and screen behavior for Godot prototype teams. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to connect successful purchase to a visible owned or quantity state. Describe the player action and visible response at each point.
Result: A clear inventory delivery 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, cancelling the action, an insufficient balance, 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 portable purchase-state design brief for a technical producer. Focus the IAP prototype on connect successful purchase to a visible owned or quantity state. 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: A browser prototype does not install Godot billing plugins or export store-ready binaries.
Keep the item optional. Show its precise Koin price, balance before spending, 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 idempotent delivery, quantity, ownership, and visible inventory state, 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.
