Preview simulates progress and scenarios without loading a real scene. Use it to inspect the presentation, then verify integration in Play Mode and on the target player.
Preview controls#
| Control | Use |
|---|---|
| Restart simulation / Pause | Replay or pause simulated time. |
| Progress / Reduced motion | Inspect a visual state or accessibility fallback. |
| Signal Game Ready | Simulate the ready visual state. |
| Simulate failure / Recover to ready | Inspect failure and recovery presentation. |
| Safe menu outcome | Simulate without actually loading a menu. |
| Authoring references passed | Source-data checks passed; no scene load or build profiling occurred. |
Try Fast and Slow for entry/exit and hint readability. Then try Failure, Unknown Progress and Missing Media. Long-text stress does not rewrite the design's authored copy.
Scenario fields#
The scenario is saved in the design. Screenshot timings are examples.
| Field | Meaning |
|---|---|
| Load Duration = 8 | Simulated work duration. |
| Fail At = -1 | No scheduled time-based failure in this example. |
| Checkpoint Delay = 0.5 | Simulated ready-checkpoint delay after load. |
| Signal Timeout = 10 | Simulated signal wait limit. |
| Long Text | Stress wrapping and bounds. |
| Missing Media | Inspect fallback appearance. |
| Reduced Motion | Static/lower-motion presentation. |
| Unknown Progress | Simulate an unavailable fraction. |
| Export issue report | Write a source-data authoring report. |
What to verify in a player#
A clean report is useful evidence, but cannot prove native video decoding, scene activation, physical-device layout or performance. Real destination timing is independent of the Preview duration. Test an actual API/trigger request and profile representative target hardware.
