Please help, I dont see anything wrong with it? And it was working earlier

[stoneharry]

When it gets to:

Sagorne:SetFaction(1732)

On line 193 it doesn't know what Sagorne is, because the unit has gone or was never defined. Hence the nil part (nil means nothing).

A solution is to either find out why it's nil (was there a typo or something? Is it spawned in game?) or add in nil checks:

if Sagorne ~= nil then -- If he is there
Sagorne:SetFaction()
end
if X ~= nil...

[weezyC]

Hmm, Idk tried putting that but still didnt work?
Siantsu and Sagorne are spawned and i have the right spawn ids
Ill just take them out

[stoneharry]

They might be too far away... The world doesn't load all the creatures at once, it only loads creatures when a player is close enough to them... So if that creature is too far away it won't have loaded and still will be nil.

[weezyC]

But the thing is the guy right next to him will change and they kill him but then it stops at Siantsu?
Ill probably just delete those for now and after im done go back respawn them and see if i get any luck

Edit:Well im about to give up cuz when i took them out it worked up to one of the last functions, But then i took one of them out that it stopped at and now it is giving me a nil value at one of the first functions. Its like its choosing where it wants to stop?

[weezyC]

Stoneharry, is there a way that i could have the db load all the NPCs in a zone at once if you enter that zone?
Cuz i think you were right when you said it doesnt load all the npcs, cuz after i run around the zone to where they are the script goes fine.
So is there a way i could have it load the zones npc if you enter the zone?

[stoneharry]

Take a look at the 'statistic_spawns' table. These should be spawns that you can see from anywhere on the same map and always stay loaded - but I have never tested it personally.

[weezyC]

Alright, ill give it a try. Thanks for the help
