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.

Next Level Does Not Load in Build

When the next level does not load, first confirm that the current level ended and that a real next destination was designed. Trace its transition action, acknowledgement and destination state. A decorative Continue button is not proof that another level exists, and a working end state should not be rewritten to diagnose navigation.

Symptom

A recognized level outcome does not lead to the intended usable next destination.

Immediate action

Identify the completed state and verify that the promised destination is actually part of the design.

Diagnostic branches

The current level has not recognized an outcome.: Investigate the end condition before its downstream transition.
No next destination has been implemented.: Correct the next-action promise to the actual finish or replay flow.
The transition acknowledges but never reaches the expected scene.: Record the last visible transition state without repeated activation.
The destination appears but cannot be played.: Request its proper starting position and control state while preserving prior completion.

Least-destructive change

Repair the real destination transition without rewriting the completed level or duplicating its rewards.

Retest

The next-action label matches an implemented destination.
The destination reaches its declared usable start state.
The earlier outcome stays recorded without another grant caused by transition retries.

Escalation

Retain the completion-to-destination trace and any exact notice if the transition remains unresolved. This page does not certify external links, audience eligibility or a particular level-loading API.

Working notes

Record the completed level and the destination the game actually promises. Is the next step another area in the same prototype, a new round of the same scene or an external game destination? Keep the expected transition specific without inventing a platform teleport or loading feature.

Observe the next-action control only if it is a harmless intended play action. Separate no acknowledgement, a visible loading state, a new scene that appears empty and a return to the old scene. If the current level never reaches completion, use the earlier end-state diagnosis first.

Check the destination's required starting state. A scene that opens without the intended player position or controls has loaded something but has not reached a usable level start. Record that partial arrival rather than repeating the transition or resetting the whole project.

If no next level has been implemented, correct the promise: offer the actual retry or finish flow the prototype contains. Do not ask for an elaborate new level merely to make an accidental Continue label true. Preserve the completed result and avoid sending players to unverified links or paid content as a workaround.

Examples

Transition trace: completed outcome visible → Continue acknowledged → next scene appears → player controls inactive. The missing boundary is a usable destination start, not necessarily completion of the old level.
Proposed repair: After the existing completion action, open the implemented next area with its intended starting position and active controls. Preserve the completed result and do not rerun the previous level's reward grant.
Prototype boundary: the game contains only the current level. Replace a misleading promise of a next level with the actual defined finish or replay choice, rather than treating a nonexistent destination as a loader fault.
