Godot · Game Designer · IAP Catalog Design guide
Use a browser-playable Godot context to produce an annotated player-flow specification. Own screen hierarchy, offer timing, readable choices, and visible feedback; 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 three-item catalog with one cosmetic, one bounded consumable, and one optional content pack. The game designer reviews item scope, price ladder, free baseline, and catalog overlap and delivers an annotated player-flow specification. Acceptance means a player can preview the offer, decline it, recover from low balance, and explain the delivered result without coaching.
Use the focused IAP Catalog Design 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.
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.
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 non-required item, its preview, specific Koin amount, current Koin balance, and ownership rule in a layout suited to Godot prototype teams.
Write how to define item identity, value, Koin price, preview, and ownership before checkout. Keep each change visible to the player rather than hiding it in technical state.
Make cancellation, not enough Koin, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use the prototype to resolve player-facing questions before creating platform integration tasks.
For a game designer, this catalog design prototype should make every player action and result shown in the game easy to evaluate. Write how to define item identity, value, Koin price, preview, and ownership before checkout. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. 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.
Run the game without opening the purchase choice, then run it with the item. Compare pacing, motivation, difficulty, and recovery so the offer supports play instead of repairing frustration that was added deliberately.
Describe what changes on screen, how long it lasts, where it appears, and what remains available without it. Replace value labels such as better or premium with rules a player can observe.
Check what the player was doing immediately before the offer and where cancel returns them. The item should arrive after enough context to understand it, but never during a time-critical or emotionally pressured action.
Use the same fields for every offer: preview, benefit, ownership or duration, full price in Koin, and owned state. Consistent cards make differences easier to understand. Test that behavior using Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
Start with one to three clearly different items. A large grid makes it harder to find unclear value, duplicated promises, and missing delivery states. Test that behavior using Godot prototype teams. A browser prototype does not install Godot billing plugins or export store-ready binaries.
A catalog also needs sold, owned, equipped, and unavailable presentations. Do not leave a purchased item looking buyable after reload. 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 define item identity, value, Koin price, preview, and ownership before checkout. Describe the player action and visible response at each point.
Result: A clear catalog design sequence
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership.
Result: Game designer focus
Play cancellation and a full session without purchase. Check timing, value, competitive impact, and whether the item matches the delivered result. Repeat the test after interruption and reload.
Result: A stable prototype
Create a portable purchase-state design brief for a game designer. Focus the IAP prototype on define item identity, value, Koin price, preview, and ownership before checkout. Use a direct Koin item transaction with preview, exact price, confirmation, cancel, insufficient balance, success, delivery, and reload behavior. The game designer must be able to connect the offer to the core loop and player motivation. 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 specific Koin amount, current Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
Own screen hierarchy, offer timing, readable choices, and visible feedback. Coordinate adjacent work, but keep the page's acceptance artifact specific to this role.
Deliver an annotated player-flow specification that records item scope, price ladder, free baseline, and catalog overlap, 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.
