Unity · Game Designer · IAP Inventory Delivery guide
Use a browser-playable Unity 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 delivered item that moves from pending to owned exactly once and appears in the correct inventory slot. The game designer reviews idempotent delivery, quantity, ownership, and visible inventory state 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 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.
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 Unity prototype teams.

Show one item that remains optional, its preview, clearly stated Koin cost, available Koin balance, and ownership rule in a layout suited to Unity 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 a cancelled choice, a Koin shortage, 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 inventory delivery prototype should make every player action and player-visible outcome easy to evaluate. Write how to connect successful purchase to a visible owned or quantity state. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Validate item value, wording, state order, and player recovery in the browser before translating behavior into Unity scenes, prefabs, services, and platform-specific implementation tasks.
Identify UI states, game-state ownership, durable entitlements, native billing adapters, security, refunds, and test environments. The playable page does not configure Unity IAP or produce a store build.
When a Unity version exists, replay the same cancel, insufficient Koin, interruption, success, delivery, and reopen scenarios. Match player outcomes rather than copying browser code or assuming parity.
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.
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 Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Use owned, equipped, unlocked, or remaining quantity as appropriate. The state should match the promise made on the offer card. Test that behavior using Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Reload the prototype and return to inventory. The item should remain visible without subtracting Koin or granting a second copy. Test that behavior using Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Choose the input and screen behavior for Unity 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
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 design reference for a later Unity implementation for a game designer. 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 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: SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Keep the item optional. Show its clearly stated Koin cost, available 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 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.
