counting npcs

[Vindicate]

Trying to count how many npcs in a room

foes = GameObj.npcs.size {|npc| npc.noun =~ /kobold/}

The problem: foes = total amount of npcs, not just the kobolds

Thanks in advance

foes = GameObj.npcs.find { |n| n.noun =~ /kobold/ }

as far as I can see that doesn't give the quantity of the creatures (in this case kobolds) in the room.

check out census or pc-census on the repo. Not exactly what you want, it categorizes critters (or people) by status. But you can probably easily edit it.

foes = GameObj.npcs.find { |n| n.noun =~ /kobold/ }

Returns an array of NPC GameObj's. Like any Array, you can .size it to determine the number of elements.

;e foes = GameObj.npcs.find { |n| n.noun == 'kobold' }; echo foes.size

Or, I think you can use the new GameObj that Tillmen did (new, as in, when I still played). Assuming I remember correctly:

;e echo GameObj[/kobold/].size

trying to size this array

Exception: undefined method `size' for #<GameObj:0xb615228>

[pabstblueribbon]

foes = GameObj.npcs.find { |n| n.noun =~ /kobold/ }

if foes.length > 3
if foes.length = 3
etc.

.find returns one, .find_all returns an array that you can get the size of.

Oh yah, that. I shouldn't be trying to give Ruby help when I haven't touched it in a long time.

Ditto.

Your idea was sound, always thought .find created an array as well.

And that is what was screwing me up.
