02 / Timing preview
Markers show straight-down motion. This is a timing preview: no collisions, combat, path following or enemy AI. Map IDs to your own scenes in Godot.
From JSON to a running Godot scene
The optional example project includes the scheduler, three editable wave files, geometric placeholder scenes and installation notes. Connect spawn_requested to your own scenes; pause, cancel and restart are included.
Get the Godot source project — $5. The browser editor and JSON export remain free.
