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.

Roblox Build Not Working on iPhone

For an iPhone problem, first distinguish the Roblox app from a browser page or a game link. Then identify whether the missing response is the Build entry, its account requirement or an interaction inside an opened project. Old claims that all iOS access is unavailable are not a substitute for the current checklist.

Symptom

Build seems unavailable or an intended creation action fails on iPhone.

Immediate action

Name the actual surface and whether the issue occurs before or after the creation interface opens.

Diagnostic branches

The observation comes from a browser article or published-game link.: Check the documented mobile-app creation entry separately.
The app entry is absent or displays a requirement.: Use the relevant access or requirement guide rather than input troubleshooting.
The interface opens but the keyboard changes what can be seen.: Record the field and action visibility before treating the submission as failed.
A request may already have been sent.: Inspect its acknowledgement, notice or result before sending another message.

Least-destructive change

Clarify the app/browser and input-state boundaries while preserving the existing project and request history.

Retest

The comparison uses the creation surface rather than only a playable-game link.
Text entry and confirmed submission remain distinct events.
The report records any keyboard-related occlusion rather than assuming an account restriction.

Escalation

If the actual app workflow still fails, send official support the surface, device/app context and precise input or access state. Do not install unofficial Build profiles or share credentials with a purported unlock service.

Working notes

Record the surface you are actually using. A browser article describing Build or a link to a published game does not show the account's creation navigation. Follow the documented mobile-app entry path before concluding that the creation tab is absent.

When an input field is visible, note what happens before and after the keyboard appears. The field accepting text, the action remaining visible and the submission producing a response are separate observations. A control temporarily outside the visible area is not necessarily a failed request.

Do not send the same prompt again while its state is unclear. First check whether a request was acknowledged, a usage notice appeared or a result is already present. A duplicate request can make the record harder to interpret without resolving the original display question.

Treat a failure in a published game's controls as a different problem from creation access. Keep the destination and project version in the report. Opening another game's link cannot demonstrate that your account's Build editing workflow is available.

Examples

Surface correction: the reader sees a Build article in a browser but no creation navigation. The next observation belongs in the official Roblox app, not in a search for hidden controls on the article page.
Input trace: field selected → keyboard appears → text entered → action visibility recorded → request outcome observed or unknown. Preserve that sequence before repeating a submission.
Context split: a published game opens on the phone, while the creator's Build entry is absent. Record player access and creation access separately instead of treating either result as proof of the other.
