Plan and test game mechanics

A mechanic needs an observable rule: an action, a change in state and feedback to the player. Before adding more systems, test whether the first action, win condition and restart work together. The existing guides below provide the starting workflow and debugging checks.

Prepare a game for publishing

Publishing starts with a game that can be tested, understood and maintained. Check the available creator controls, audience settings and safety requirements before a release. Use the publishing guide for the sequence, and the troubleshooting guide for an actual blocked step.

Diagnose an Obstructed Build Control on iPad

After the creation surface has opened on iPad, localize the exact action that cannot be reached: off-view, covered, or visible but unresponsive. Compare the same target under a safe view change and stop once the failure class is clear. If the entry itself is missing, use the separate access guide instead.

Symptom

Creation access is already established on iPad, but a named target cannot be reached or does not respond in the current view.

Immediate action

Fix the project and target in the baseline, then identify a safe single view change or stop if none is available.

Diagnostic branches

The creation entry itself has not been opened.: Use the access guide; this post-entry obstruction test does not establish eligibility.
A safe view change reveals the target previously covered by an identified surface.: Record the covered classification and the exact view transition without inferring a backend cause.
The revealed target still gives no acknowledgement when safely selected.: Keep the resolved visibility issue separate from the remaining response failure.
No safe comparison can be made without losing unfinished work.: Preserve the baseline and mark the alternative view untested.
Only the generated game's controls overlap.: Use the game's mobile-layout diagnosis with a marked view of the overlap.

Least-destructive change

Change only an ordinary safe view condition while retaining the project and unfinished input; do not send a new generation to diagnose the interface.

Retest

The same target and project appear on both sides of the comparison.
The record distinguishes a revealed target from a responsive target.
Only the actually changed view condition is credited in the result.
Untested or unsafe comparisons stay explicitly untested.

Escalation

Provide official assistance the redacted initial view, single view change and resulting classification, including any remaining response failure. The packet should identify a reproducible boundary without claiming its technical cause.

Working notes

Freeze the project, target and intended action in the baseline. Record the current view arrangement and what covers or surrounds the target. Do not rotate, resize, change input method and send a request together: if the result changes, that mixed experiment would not isolate the useful observation.

Choose a non-destructive comparison that the real interface offers, such as dismissing an on-screen keyboard through its ordinary control without losing the draft. Record the same target afterward. If no safe view comparison exists, stop and keep the initial screenshot rather than discarding work for a reproduction.

Classify the result from visible evidence. Covered means an identified surface overlaps the target; off-view means its location is outside the currently shown area; visible-but-unresponsive means the target can be seen and selected but no expected acknowledgement is observed. Do not infer the internal layout or event-handling cause from these classifications.

Produce the reproduction packet only after the comparison. State the initial view, the single view change, target visibility before and after, and response if safely checked. Keep untested input methods and orientations explicitly untested. If the affected target belongs to the generated game rather than the creation interface, hand off that packet to the mobile-game-layout guide.

Examples

Worked hypothetical: the project and text draft stay unchanged; the on-screen keyboard overlaps a named action; ordinary keyboard dismissal reveals that same action. Classification = covered in the initial state. Next output = the view-change reproduction packet, not a new account-eligibility test or a generated layout repair.
Different result from the same safe comparison: the target is revealed but selecting it produces no acknowledgement. The occlusion was real, yet it does not explain the remaining response failure. Record both stages and investigate the opening/submission action separately without sending duplicates.
No-safe-test outcome: dismissing or leaving the current surface may discard unfinished input. Preserve the baseline and mark the alternate view untested. A reproduction packet can be useful without pretending every condition was exercised.
