 Values in between represent varying degrees of health for the wall.
 === Examples ===
-Spawn walls under this unit based on its cell width and cell height. Repair these walls every 10 seconds, effectively making them Crazonium (invincible) walls.
+This script will check if there is any single wall piece under the CRPL core this script is attached to. If there is, it will trace 1 (TRUE), if not, it will trace 0 (FALSE).
