WorldGuard

SmartSpawner maps each spawner action to a WorldGuard region flag.

Action	Flag
Open menu	interact
Stack	block-place
Break	block-break

The check uses WorldGuard's build test, so region members are always allowed. For non-members (for example a public or global region) you must enable the flags explicitly.

Allow spawner use in a region

/rg flag <region> interact allow
/rg flag <region> block-place allow
/rg flag <region> block-break allow

Block spawner use for everyone

Setting a flag to deny blocks it even for members:

/rg flag <region> interact deny

To apply the rule to a whole world, set the flags on the __global__ region.

Bypass

Operators and players with worldguard.region.bypass ignore these flags.
