"Invalid TARG ... xt retn subr normal {@}subv ov02 10 doif ov10 = -1 re ... " Thanks CLohse's Norns at the Creatures Repository   Malkin Manager     7/30/2013 Per the example of this thread, maybe the code only knows that it errors when it gets to that point, it can't definitively tell you that that exact line is the culprit. What's happening before the subroutine? Can you follow along with what the agent is TARGing? My TCR Norns   Mad Scientist clohse     7/30/2013 This is for a critter and the error occurs after it has eaten food and is going back to wandering around. During the eat subroutine it TARG's the food, moves over to it, kills it and increases energy. My feeling is that I am forgetting what happens when the agent that is TARG'ed is killed. Is the TARG automatically set back to ownr or do I need to put it in there. I tried both ways and it didn't matter. CLohse's Norns at the Creatures Repository   Malkin Manager     7/30/2013 Are you following along from Ghosthande's Hungry Critter Tutorial? Have you tried instead getting the critter to trigger the food's eat script? My TCR Norns   Mad Scientist clohse     7/30/2013 yes, I was and no I haven't. I will give that a try tonight after I tuck in my own baby norn. Thanks for the ideas. EDIT: I made the change in the eat from kill to mesg writ. It seems to run a little smoother while eating, but the same error still pops up. Here is the entire timer script.

The snotrock cos file, which Ghosthande based her tutorial hunt script on, after the ESEE, checks the RELY (relative height) of the target foodstuff, then checks the RELX of the target foodstuff, then, if it's 'within reach', sets va02 as targ. The snotrock has ov16 as its' 'food target'. Maybe after the target agent (the food) is killed, the TARG becomes null, which freaks the critter out? * search for food close by rnge 200 setv va00 10000 seta va02 null inst esee 2 11 8 * only check tuba that can be eaten doif ov05 eq 1 * only check food roughly on the same height setv va01 rely ownr targ doif va01 lt 0 negv va01 endi doif va01 lt 100 setv va01 relx ownr targ doif va01 lt 0 negv va01 endi doif va01 lt va00 setv va00 va01 seta va02 targ endi endi endi next * if found some change mission to approach food doif va02 ne null seta ov16 va02 setv ov00 3 * otherwise walk in a straight line searching else gsub walk endi endi *approaching food doif ov00 eq 3 inst targ ov16 doif targ ne null setv va00 posx else targ ownr setv ov00 2 endi targ ownr slow * if you're facing the wrong way turn around doif posx gt va00 and ov10 gt 0 call 1000 0 0 elif posx lt va00 and ov10 lt 0 call 1000 0 0 endi gsub walk inst doif ov16 ne null doif touc ownr ov16 eq 1 gsub eat endi else setv ov00 2 endi slow endi My TCR Norns   Mad Scientist clohse     7/31/2013 yay!

My TCR Norns   Mad Scientist clohse     7/31/2013  1 I had too many gsub normal statements. I just took them out. CLohse's Norns at the Creatures Repository
