Umm... that doesn't answer my question (perhaps I asked it badly?). Food items do show up in inventory. What I'm wanting to do is to give the player a choice to give a (generic) food item to a NPC.

Obviously, the option should only come up in dialog if someone in the party actually has a food item. But I don't care WHAT particular food item (fish, bread, steak, whatever) it might be.

So... do I have to check for each food item the party MIGHT have individually (until I find one or work through every possible food item), or is there an easy way?

Is there an easy way to check if the party has any food items and take one away? Without checking for each individual type of food item, that is.

There are probably some optimizations that can be made to this (I'm an Avernumscript noob), but it should be pretty safe and generic. Enjoy!

At the risk of making a pest of myself, I'd like to know why this doesn't work. I decided to code around the problem with damage_near_loc passing through walls, and came up with this:

beginstate 3; // attacking	...stuff here that's ok...			// time to spit more poison?	if (tick_difference(last_abil_time, get_current_tick()) > 1) {		// don't use damage_near_loc, because it damages where it shouldn't		i = 0;		while (i < 4) {			distance = char_dist_to_loc(i, my_loc_x(), my_loc_y());			if (distance == 1) {	// character is adjacent				print_named_str(ME, "spits poison!");				play_sound(42); // acid hiss				damage_char(i, get_ran(3, 1, 3), 2);			}			i = i + 1;		}	}		do_attack();break;

EDIT: DOH! It's always the simple gotchas. Adding last_abil_time = get_current_tick(); before the last curly bracket makes it work as expected. Sorry 'bout dat!

You wouldn't need AoE spells to have what (to me) would be correct behavior for this call. Seems to me it would just be a check with the pathfinding algorithm to see if the path from the damager's current loc to the loc in question is range squares or less. Sure, my spider COULD go out the door, around the building and into the shop in question, but not in 'range' moves. So it shouldn't do damage there.

Of course, not knowing the particulars of the implementation, such a call to the pathfinding algorithm might be prohibitively expensive. In that case, current behavior would be correct (not to say optimal ).

-spyderbytes

OK... I decided my spiders still weren't quite challenging enough, so I decided to have them spit poison every couple of turns to soften up the melee types standing adjacent to them and hacking at them. damage_near_loc seemed the perfect candidate for that, and works perfectly EXCEPT... a shopkeeper on the other side of a stone wall from the spiders also gets poisoned.

It's a simple enough matter to move the shopkeeper far enough away from the wall to not get poisoned. I just expected intervening impassible terrain to block the damage, so I'm wondering if the current behavior is intended or a bug.

-spyderbytes

Hmmm... good point, so I changed it. Thanks for the tip!

-spyderbytes

I'm not sure I understand why that would be safer, at least as long as I'm sure (and I am) there's no chance of other hostiles nearby in this particular town. Am I missing something?

-spyderbytes

Actually, my jug-guardian spiders already have a custom script for some custom targeting AI, so that part isn't a problem. What was originally holding me up was trying to figure out how to give the special item when the last spider died, and not for each one (and that's why I wanted to place it in a nearby container, as I would a normal item).

But then I discovered friends_nearby, and now all's well with the world. I've changed it so I'm granting the special item when friends_nearby returns 0 (meaning all the others are already dead when this one dies). So, problem solved.

Thanks for the help!

Ah... no wonder I couldn't tell any difference switching a lone hostile creature back and forth between Type A and Type B.

I hadn't even gotten around to thinking about factions yet, but nice to know it's covered, at least in a basic fashion.

-spyderbytes

The docs for special items seem pretty skimpy (to say the least). Is it possible for the party to find a special item in, say, a crate (after killing the monster guarding it)? Or does it have to be granted programmatically?

If the former will work, how? I can't figure out how to place anything but regular items in the editor.

I can't find anything on this in the docs... what's the difference between Hostile, Type A and Hostile, Type B?

-spyderbytes

I've only managed to skim the first seven(!) pages, so forgive me if this has been mentioned... but what I most want GF3 to be is "Blades of Geneforge". That is, give us an editor and let us write our own scenarios set in the GF mythos.
