# 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: ```lua 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.
