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 Access Changed

When Build remains visible but an action or requirement changes, record the exact old and new state before treating it as lost access. A new usage notice, an account requirement and a removed control are different problems. Investigate the changed boundary rather than restarting every eligibility check.

Symptom

Build remains visible, but a formerly usable action now has a different requirement, notice or control state.

Immediate action

Identify the specific action and compare its earlier result with the current blocking state.

Diagnostic branches

The entry itself is now absent.: Use the disappeared-tab regression guide instead of this visible-access transition.
A usage message now blocks a creation request.: Use the allowance guidance and inspect current controls without making a diagnostic purchase.
A verification or eligibility requirement is explicitly shown.: Follow that legitimate requirement and retain the transition record.
A control is missing or changed with no explanation.: Document the actual surface and seek current official workflow clarification.

Least-destructive change

Investigate the changed boundary without undoing unrelated account or project settings.

Retest

The comparison names the same action on both sides.
Still-usable actions remain recorded rather than summarized as total access loss.
A usage condition is not relabelled as a region or age restriction.

Escalation

Send official assistance the exact transition, known intervening actions and redacted notice when no documented path explains it. A changed interface alone does not establish a penalty or entitlement removal.

Working notes

Name the action you could previously complete. Editing a prompt, opening a project and entering a published game are not equivalent access tests. A report saying only that access changed leaves the useful distinction unresolved.

Copy the notice or control state that now blocks the same action. If the message concerns usage, route it to allowance or purchase-control guidance without assuming the account lost creator eligibility. If it concerns age verification, preserve that requirement rather than diagnosing a generated-game defect.

Separate a removed control from a relocated or newly obscured one. Record the current surface and what is visible; do not invent a replacement location. If the old control cannot be found, keep that as an observation until a current official path explains the change.

Do not reverse every recent account or project change in search of a cause. The safer output is a transition record with known intervening actions and the new boundary. It can support a targeted next step without discarding the current working version.

Examples

Transition: prompt field still accepts text, but sending now displays a daily-usage notice. Creation-entry visibility is unchanged; the next question concerns usage, not disappearance of the feature.
Different transition: a previously usable entry now opens a verification requirement. Preserve the requirement and earlier confirmed state rather than repeatedly sending a game prompt.
Control-change note: previous action label and context / current surface / exact notice or missing control / actions still usable / known intervening event. This does not assert why Roblox changed the state.
