unit:toughness¶
Read the observed toughness label and number, or nil.
Signature¶
Contract and usage¶
unit:toughness()¶
Returns two values: a toughness label and its numeric value. Returns nil when
no recognized toughness value is available.
Unit Identity And Lifetime¶
Every GosUnit state-reading method raises stale_unit after its world
generation expires. unit:handle() is the exception and remains available so
the unit can be reacquired with a fresh world:resolve(handle).
Within one world, repeated lookups of the same unit compare equal with ==.
Values from different generations compare unequal even when their handles
match.
