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 Will Not Open

If the Build entry is visible but selecting it seems to do nothing, record whether the action is acknowledged and whether another surface or notice appears. This is different from a missing entry. Avoid repeated taps or unrelated account changes while the result of the original action is unclear.

Symptom

A visible Build entry can be selected but no usable opening result is observed.

Immediate action

Observe the selected target, any acknowledgement and the resulting screen before repeating the action.

Diagnostic branches

The intended target is covered by a keyboard, menu or dialog.: Record the obstruction and use safe ordinary dismissal before comparing visibility.
A loading indicator or changed surface appears.: Treat the selection as acknowledged and investigate the later loading state.
An explicit requirement notice appears.: Follow that requirement instead of diagnosing a silent control.
Build opens but a particular project does not.: Use project-opening diagnosis with the exact selected project.
No transition is visible and ordinary navigation still works.: Record the isolated no-response action for official assistance.

Least-destructive change

Inspect the original action's acknowledgement and target visibility without repeated submissions or data removal.

Retest

The intended target is actually visible when selected.
An acknowledged loading transition is not called an unresponsive tap.
The report names whether the failure is entry-level or project-specific.

Escalation

Give official support the redacted action trace, input method and app/device context when the visible control produces no explained result. Do not infer a permission or backend cause from silence alone.

Working notes

Describe the visible control and selected action without inventing how it should respond. Note any pressed state, loading indication, changed heading or requirement notice. Even an incomplete transition helps distinguish an input problem from a later loading problem.

Check whether another visible surface covers the intended target. A keyboard, menu or dialog can change where an action lands. Record the obstruction rather than assuming it caused the failure, and only dismiss it through its ordinary control when doing so will not discard work.

Keep entry opening separate from project opening. If Build itself opens and only a particular project fails, preserve that project identity and use the project-specific guide. Repeating a whole-account eligibility checklist would miss the narrower boundary already established.

Do not manufacture a response by selecting several controls in quick succession. That can make it unclear which action produced a later result. A useful report names the original target, a bounded observation and the actual state reached.

Examples

Action trace: entry visible → selected once → no changed heading, notice or progress state observed → ordinary navigation still responds. This is a no-observed-transition report, not proof that the account lacks eligibility.
Acknowledged action: selection produces a loading indicator. Continue with the loading guide rather than describing the control as never responding.
Target distinction: Build navigation opens normally, but selecting an existing project does not. Carry the project name and exact result into project-opening diagnosis.
