T4 Modules Howto Guide/Resolvers
Entities work with resolvers. Basically, every time you need a given entity to be different from other entities created from the same table. For instance, this allows every orc to have a slightly different equipment - by using an equip resolver.
Resolvers can have a _resolve_last flag set, this means they only get resolved on the last pass in entity creation (after all egos are applied).
Entities can also have an instant_resolve flag, which is especially useful for appending to names and/or egos.
Resolvers basically are there to let you postpone some stuff in entities. You *could* write a field like that in an entity:foo = rng.range(1,10)
But the call to rng.range would happen when the entity files is loaded and thus set the value in stone for all entities cloned from it. If instead you usedfoo = resolvers.rngrange(1, 10)
Then it would take its value only when the entity has been cloned, making sure every clone has its own random value.
