Nope, you're a little wrong.
By using those functions you currently only check if creature is you itself, your target or creature that you follow.
He had in mind something like $self, $target, $attacked, $followed in neobot. Those variables was returning creature pointers.
Also I want to know if there will be some variable or loop like in neobot that would be returning all creatures (players/monsters/npc's) from screen (all floors)?
