First playable scene

Prerequisites: a working Rustic installation, a writable project opened from Project Manager and a desktop graphics session. This Lua example needs no optional external language toolchain.

1. In Project → Scene → + Add, add a primitive and select it. Rename it Player in Inspector.
2. Set Anchored so gravity does not move it during this logging-only exercise.
3. Add a Camera, then use Align to editor view and enable Active so the primitive is visible in Play.
4. Select Player and choose Programming → Object Component Script → Lua 5.4. Open the created source in the external editor and replace it with:

return {
  Start = function()
    rustic.log("info", "Player started")
  end,
}

5. Save the source and scene. Check Gameplay scripts in Inspector to confirm the attachment is enabled.
6. Press Play. Expect the primitive in the game-camera view and Player started in Console.
7. Pause, use Frame, resume, and stop. Discard runtime changes for this exercise.

Diagnose the result

No message: check the selected entity's attachment and Enabled state, syntax and callback spelling. A blank game view: check Active camera, its position and orientation. A startup error: inspect Console and verify the runtime executable is installed.

This exercise validates attachment and startup, not movement or HTML layout. Continue with the Lua keyboard controller and Playtesting. Use Editor overview for panel navigation.
