[Crash] World Editor Crashes on hash tables

[Saito]

Hey.
I try to add a region handle into my hashtable. But when I want to save handle of the region trough GUI(Hashtable - Save region), application stops responding and crashes. The same thing goes with unit groups.
Any ideas what is the cause of this?

There is no solution to this, they are simply broken.
I hear you have to downgrade your patch to make them work, because I think I read that they used to work. But that's not a solution in my world.

It's quite possible that it works in jass though.

You the custom script action in GUI and use these JASS functions:

native SaveRegionHandle takes hashtable table, integer parentKey, integer childKey, region whichRegion returns boolean

native LoadRegionHandle takes hashtable table, integer parentKey, integer childKey returns region

There are some things incorrectly implemented for the hashtable. The same thing happens with ability handle.
My guess is that it is supposed to take in a region (jass region), not the rectangular region you're writing about (called rect in jass).

Edit:
Just got back from testing to see people answered earlier than I did.

You the custom script action in GUI and use these JASS functions:

native SaveRegionHandle takes hashtable table, integer parentKey, integer childKey, region whichRegion returns boolean

native LoadRegionHandle takes hashtable table, integer parentKey, integer childKey returns region

That is incorrect. Jass region != GUI region. Instead, Jass rect == GUI region.

But yeah, Emm-A basically got it right. It does work if you use jass script.
Check the attached test map to see how it's done.

Sry, but also in GUI trigger editor, a region is a region and a rect is a rect. There is a SaveRectBJ and a SaveRegionBJ ...

If you use the SaveRectBJ in GUI, it does not crash the WE in contrast to SaveRegionBJ. Thats why the 2 natives I posted, are the correct solution for his problem, and you should not mix up definitions for the sake of clarity.

There may have been slight misunderstanding. What I meant as GUI region was everything region-related in GUI (e.g. move region, set point at region, region palette, etc.), just now, after reading your post I checked and saw that there is actually an action in the hashtable list for also saving a rect.

So if you meant that GUI region == Jass region in the hashtable menu, then you are correct. If not, you are incorrect and I can easily prove that to you.

It is a bug from when they introduced hashtables. They thought that the "ability type" and "region" JASS types were the same as their corresponding GUI types, which they are not. In GUI an "ability type" is actually an integer while a "region" is a rect. The crash occurs because it tries to access a type which does not exist in the GUI editor and such a case is not handled gracefully.

The solution, and recommendation, is to move to pure JASS since frankly the WE GUI editor is terrible.
