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 Character Generation

Characters are included in the generation scope described by Creator Hub. Define the figure's role and observable behavior as well as its appearance, then inspect the relevant input response and interaction boundaries; a convincing character model alone is not a working character system.

Objective

Separate character appearance from role, interaction and reset requirements.

Before you start

Name the figure's gameplay role.
List which actions belong to the player and which belong to the figure.
Use an original visual concept and a small inspectable behavior scope.

Steps

Write separate appearance and behavior briefs.
Identify the trigger that starts or changes the character's response.
Inspect contact and movement against visible boundaries.
Check what the character does after completion, failure and retry.
Revise the failed responsibility while preserving working ones.

Verification

The figure's role is clear without relying on costume alone.
The visible interaction region matches the observed contact outcome.
A visual edit does not silently change the movement or response contract.
Retry returns both the player and relevant non-player figures to their intended state.

Limitations

A generated figure does not establish platform-avatar editing or persistent companion functionality.
Specific rigging, animation or AI behavior needs its own evidence and inspection.
The sample role cards describe intended behavior, not a feature certification.

Working notes

The word character can hide several different requests. A player-controlled courier needs readable movement and contact behavior. A stationary guide needs an identifiable location and useful feedback. An opponent needs a predictable relationship to the player, including what happens after defeat or restart. Do not treat these roles as interchangeable because they share a visual theme.

Write appearance and behavior in separate parts of the brief. Appearance covers silhouette, contrast and recognizability. Behavior covers triggers, movement constraints, responses and reset. If only the costume needs changing, explicitly preserve the inspected interaction rather than asking for a vaguely improved character.

Inspect the relationship between the visible figure and its effective interaction area. A character that appears to avoid an obstacle but still collides with it produces a different defect from a figure whose motion is delayed. Record where the discrepancy occurs and whether it depends on direction, proximity or another nearby object.

Keep identity and ownership boundaries clear. An original in-game figure is not evidence of a custom platform avatar, a reusable rig, account-level ownership or a persistent companion. Avoid recognizable protected characters, and investigate any advanced character workflow separately instead of inferring it from the general generation description.

Examples

Role card for an original lantern guide: remains beside the starting path, changes its message after the parcel is collected, and does not block the route. Visual brief: an easily distinguished silhouette and readable cue. These are proposed responsibilities, not confirmed built-in controls.
Opponent inspection note: approach before contact, after contact and after retry. Record the figure's location, the player's state and the feedback at each point. A convincing chase animation does not answer whether damage or failure is applied correctly.
Bounded appearance request: 'Change the courier's coat to a bright raincoat so it stands out from the street. Preserve movement speed, parcel interaction and the existing retry behavior.' Verify those preserved behaviors after the visual revision.
