You can make multiple of these for whatever maps and they persist for each map.

Put spawnprotect in the console while aiming at a position for the first corner and spawnprotect again for the second corner opposite the first and the shield will be made and saved to a file. This creates a box around the where ever you were aiming that collides with everything except players and if anything with physics movement gets into it, it is deleted.

Use spawnprotect_clear to clear the map of spawn shields.

Only super admins can use these commands.
