Hi.

I was able to make this crash happen by calling DestroyItem() in a script ran from an item's EquipScript. Is this what you are doing? If so, why are you trying to destroy the item when the user is equipping it? Doesn't really make much sense to me.

Thank Kevin. It can be truth, I'll check it.

Because I have some item and they have to lose the durability when they to equipping.
But when it happen, I return 0 from equip script.

Code: Select all

var time:=GetObjProperty(item,"#timed");
if (!time)time:=0;endif
if (time>5)
	CheckToolWear (who, item,4,10); //this function subtract HP of item or destroy it
endif
					
if (item)
	SetObjProperty(item,"#timed",time+1);
	return 1;
else
	return 0;
endif
Have I to do it in equiptest script?

But!!!
Item 0x705A5555 doesn't use this block.
When item is using, another script try destroy it. At this time somebody try equips this item. And when the core try destroy the item, the item have not equipped and have not exist in world

And I think whatever I will do in scripts, it doesn't have to crash the core isn't it?

Nothing done in scripts should crash the Core. You are correct but I think Kevin asked the question to gather information about how this occurred to try to find the cause. They are working hard on finding the solution and more information can be very useful.

I would tell you a UDP joke but you might not get it.

It's alright. I don't know your primary language but I promise you that you speak better English than I would be able to speak your language :)
