This example composes EVEngine's UI-neutral editor SDK into a project-specific combat action editor. It uses the canonical eve.action.timeline asset model, native hit testing and drag preview, one-step transactions, undo/redo, and deterministic preview events. The 3D viewport is driven by the same preview cursor as the timeline.

Run on Windows:

make run/win32-debug GAME=examples/combat-action-editor

Controls:

Click Melee 1H Attack Chop to select and replay the authored action.
Play / Pause and Restart control deterministic action preview; Space toggles playback.
Click empty timeline space to seek.
Drag an item body to move it; drag a state edge to resize it.
Edit the selected hitbox start/end in the inspector sliders.
Undo / Redo (or Ctrl+Z / Ctrl+Y) operates on the native timeline transaction history.
Hold the right mouse button over the preview to orbit; use the mouse wheel to zoom.

The preview and timeline headers show the current selection, playback state, edit revision and the last emitted event so every interaction has visible feedback.
