Is it possible to create a global variable, i.e a game's attribute in a library? Just because the library will be simpler to use.
Thanks,
Thierry

for quest, Attributes are its global VARIABLES (as long as the Object that holds/contains the Attribute, exists / still exists, of course)

Attributes must be inside of an Element (Object, Verb, Function, Turnscript, Object Type, etc):

// 'mygame.aslx' Game File:

<asl version="550">
  <include ref="mylib.aslx" />
</attr>

// 'mylib.aslx' Library File:

<library>
  <attr name="strength" type="int">100</attr>
</library>

// ERROR!

VS

// 'mygame.aslx' Game File:

<asl version="550">
  <include ref="mylib.aslx" />
  <object name="room">
  </object>
</attr>

// 'mylib.aslx' Library File:

<library>
  <object name="HK">
    <attr name="parent" type="object">room</attr>
    <attr name="strength" type="int">100</attr>
  </object>
</library>

// NO error

oh... you mean actually with the 'game' Game Object's Attributes?

I don't think so... well... maybe you can have the 'game' Game Object, be in a library... depends how the quest initialization process/order works... no idea if you can or can't...

it would look like this:

// 'mygame.aslx' Game File:

<asl version="550">
  <include ref="mylib.aslx">
</asl>

// 'mylib.aslx' Library File:

<library>
  <game name="xxx">
    <attr name="state" type="int">0</attr>
  </game>
</library>

// but, I don't know how the initialization works, in whether you can have the 'game' Game Object (and thus its Attributes inside of it), initialized from a library file, or whether your 'game' Game Object MUST be in your game file.

// Quest requires: the 'game' Game Object' and a Player Object to be inside of a Room Object

Quest does not support global variables as such. Instead, create an object in the library, and set its attributes.
