      (([ballSpeed v]) * (1.1))
      ```
    - **Every hat block script must end** with a final `end` on its own line.
+   - **Indent nested blocks by 4 spaces under their parent (`forever`, `if`, etc.).This is a critical requirement.**
 3. **Opcode Lists**: include relevant Scratch opcodes grouped under `motion`, `control`, `operator`, `sensing`, `looks`, `sounds`, `events`, and `data`. List only the non-empty categories. Use exact opcodes.
 4. Few Example of content of logics inside for a specific plan as scratch pseudo-code:
