Pacing
Check dialog order, title-card timing, waits, choices, and the feel of a scene.
Preview & Output
Preview is the fast feedback loop. Output is the place to look when that loop cannot continue.
Together, they help you catch missing connections, missing assets, invalid variables, and unreachable paths before you test the installed runtime.
What preview is for
Section titled “What preview is for”Presentation
Check backgrounds, overlays, sprites, effects, audio changes, portraits, and scroll sounds.
Branches
Try each choice path and condition path before the route becomes large.
Quick fixes
Use Properties warnings and Output messages to repair the current path.
Start preview
Section titled “Start preview”- Resolve required Properties warnings on the scene or route you want to test.
- Compile the project.
- Choose Preview > Start Preview.
- Use Step Forward to advance manually.
- Use Play / Pause when you want automatic preview playback.
You can also start from a selected node with Preview From Here. This is useful when a scene is long and you only need to test a late branch.
Preview controls
Section titled “Preview controls”| Control | Use it for |
|---|---|
| Start Preview | Start from the selected preview start scene. |
| Preview From Here | Start from a selected node in the current scene. |
| Set as Preview Start | Make a scene or chapter the default preview start. |
| Step Backward | Rewind one preview action. |
| Step Forward | Advance or redo one preview action. |
| Play / Pause | Toggle automatic preview playback. |
| Preview Render Size | Switch between 720p and 1080p logical preview sizes. |
What Output tells you
Section titled “What Output tells you”Output reports missing required links, missing assets, unsupported field values, and story structure problems found during compile.
Output and the status bar report actions such as asset imports, project saves, runtime installs, and preview start changes.
Warnings are not decoration. They tell you which field is likely to stop a route from behaving the way you expect.
Preview limits
Section titled “Preview limits”Preview can simulate many story choices, timers, text input, sprite activation, and world triggers. It cannot prove everything that happens in a Roblox play session.
Use Testing Runtime for saves, settings, text filtering, player movement, teleport destinations, click/touch triggers, and custom runtime behavior.
When preview and Output agree, you have a good authoring signal. When the installed runtime also behaves correctly, you have a route you can build on.
