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 · Godot Prototype Teams · Koin purchase UX
Use a browser-based playable build to work through purchase confirmation for Godot prototype teams. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
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 that remains optional, its preview, clearly stated Koin cost, available Koin balance, and ownership rule in a layout suited to Godot prototype teams.
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 cancelled choice, a Koin shortage, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Map preview, confirmation, cancellation, not enough 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 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. 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.
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 Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
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 Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
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 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 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 cancelled choice, a Koin shortage, 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 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: A browser prototype does not install Godot billing plugins or export store-ready binaries.
Keep the item optional. Show its clearly stated Koin cost, available Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
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.
No. The player spends Koin directly on one named item or unlock.
Return to the same game state without spending Koin or delivering the item.
Explain the shortage, preserve progress, and do not deliver the item.
No. It covers the player-facing purchase experience, not financial reporting.
No. A browser prototype does not install Godot billing plugins or export store-ready binaries.
