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 Tab Crashes

If the app closes when you enter Build, preserve the last visible action and distinguish an app exit from a frozen or loading screen. Do not repeatedly trigger the crash or clear data to test a guess. A crash report should identify the failing boundary without inventing its technical cause.

Symptom

Selecting Build or a related creation action causes an apparent app or surface exit.

Immediate action

Record the last visible action and what closed, without deliberately repeating a potentially destructive failure.

Diagnostic branches

The entire app exits to the device screen.: Prepare an app-exit report with the last action, device/app context and any notice.
Only the game or Build surface closes while ordinary navigation remains.: Describe the narrower surface exit and selected project.
The screen remains open but stops responding.: Use frozen/loading-state diagnosis rather than claiming an exit.
A charge and absent result are also independently observed.: Preserve those records and use the dedicated charge-without-output path without repurchasing.

Least-destructive change

Use existing observations, preserve project identifiers and avoid repeated crash reproduction or data clearing.

Retest

Any repeated occurrence is labelled observed, not assumed.
App exit and game-view exit are distinguished.
A crash is not converted into a claim that projects, credits or account access were lost.

Escalation

Send official support the redacted crash packet and clarify whether active work was in progress. Supply additional diagnostics only through legitimate assistance and after checking them for private information.

Working notes

Record what actually closed. The whole Roblox app exiting, a Build surface returning to ordinary navigation, and a generated game ending are different events. Include the last visible screen and any message so the word crash does not hide the distinction.

Use an already observed reproduction when possible. You do not need to repeat a failure that could interrupt generation or risk unfinished work just to make a report sound stronger. Mark a single observed event as such and distinguish it from a safely confirmed repeat.

Keep device and app context without assigning a diagnosis. A crash on a particular model does not establish insufficient memory, an unsupported chipset or a server outage. Official help may request additional information, but this guide does not invent error-code meanings or collect full diagnostic logs containing private data.

Preserve project identity and purchase context if relevant. An exit during generation does not by itself prove that output was lost or that a charge should be refunded. If a completed charge and missing output are separately observed, use the dedicated billing/output guide rather than reopening the app to buy another attempt.

Examples

Crash packet: app was open → Build entry selected → last visible label → app exited to the device screen → no error text observed. This is an app-exit observation, not a claim about memory or service health.
Different event: the game view ends and ordinary Roblox navigation remains usable. Record the game-view exit separately from a whole-app crash.
Preservation choice: the failure occurred during an active generation. Keep the request time and project identity; do not repeatedly reproduce it or assume the result was deleted.
