How to actually remove item from container?

I asked this in an other thread, but because that was about a completely different subject, I started this thread.

I want something removed from a container. Say I have a matchbox, I open it and find a match inside. with Take match, i pick it out of the container and place it in my inventory.

But how can I make sure that the match is actually out of the box, so that when I open it another time it won't show the: there is a match inside, but rather: there is nothing inside

Hope someone can help me.


The container should state that it contains a match when examined . If the match is removed, then that message will disappear. The match will appear in your inventory. The program will handle all this automatically.


Can you state this in the program itself, in the object options? Or do you have to code this yourself?
I can not find it


The tutorial covers this:

Thanks! Followed that one but did not work. Now I realize that I had also a print to show when it was opened. I forgot to remove that one, so that's why I thought it did not work because the print contained (almost) the same text :)

And I completely looked over 'List children when object is looked at or opened' That was what I needed


containment/child-parent (think of folders on your computer) heirarchy:

grandfather
-> father
->-> son
->->-> grandson

root (main) parent: grandfather

grandfather's direct child: father
grandfather's indirect child: son and grandson

father's direct parent: grandfather
father's direct child: son
father's indirect child: grandson

son's indirect parent: grandfather
son's direct parent: father
son's direct child: grandson

grandson's indirect parent: grandfather and father
grandson's direct parent: son

HK
-> pants
->-> wallet
->->-> $1
->->-> $5
-> shirt
-> shoes
Joe
-> shorts
-> t-shirt

c:\ (drive)
-> Programs (Folder)
->-> Quest 5 (Folder)
->->-> quest's various sub folders (Folder)
->->->-> quet's various files (Files)

quest is containment/child-parent heirarchy:

the root (main) parent (container):

(this is your GAME OBJECT, your game, your game's content/code)

<asl version="550">
</asl>

everything must be inside (directly or indirectly) of the 'asl' code tag block:

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="example_object">
    <object name="example_2_object">
    </object>
  </object>
  <type name="example_type">
  </type>
  <verb name="example_verb">
  </verb>
  <command name="example_command">
  </command>
  <function name="example_command">
  </function>
  <turnscript name="example_turnscript">
  </turnscript>
  <timer name="example_timer">
  </timer>
</asl>

every 'Object' Element (not sure about other Elements) directly inside of the root (main) parent (): has 'null' Value for it's built-in 'parent' Object Attribute (though the default is to not show the 'parent' Object Attribute when its Value is 'null' and/or via nesting an 'Object' Element within another 'Object' Element):

room.parent = null

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
    // not shown 'parent' Object Attribute (because it's Value is: null): room.parent = null
    <object name="player">
     // not shown 'parent' Object Attribute (because it's code-nested-directly into the 'room' Object): player.parent = room
    </object>
  </object>
</asl>

// --------------

this is the exact same containment heirarchy as above:

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
    // not shown 'parent' Object Attribute (because it's Value is: null): room.parent = null
    <attr name="parent" type="object">null</attr>
  </object>
  <object name="player">
     <attr name="parent" type="object">room</attr>
  </object>
</asl>

so, you can see that the built-in 'parent' Object Attribute is what actually controls the containment heirarchy. The helper Function 'MoveObject (MOVING_OBJECT, DESTINATION_OBJECT)', is just doing this for you: MOVING_OBJECT.parent = DESTINATION_OBJECT

the 'RemoveObject (NAME_OF_OBJECT)' helper Function does this for you: NAME_OF_OBJECT.parent = null


also, there's this to understand as well:

(note that I'm just using the 'player' Object as an example, but do NOT set the 'player' Object's 'parent' to 'null', as this will cause an error, as quest engine/underlying-code requires that there is a designiated Player Object and that it is to be nested inside of a Room Object at all times)

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
    <object name="player">
    </object>
  </object>
</asl>

then if you do this in scripting: player.parent = null, or this: RemoveObject (player), it produces this effect (or effective new code):

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
  </object>
  <object name="player">
  </object>
</asl>

// -----------

and for this as well:

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
  </object>
  <object name="player">
    <attr name="parent" type="object">room</attr>
  </object>
</asl>

then if you do this in scripting: player.parent = null, or this: RemoveObject (player), it produces this effect (or effective new code):

<asl version="550">
  <include ref="English.aslx" />
  <include ref="Core.aslx" />
  <game name="example_game">
  </game>
  <object name="room">
  </object>
  <object name="player">
    <attr name="parent" type="object">null</attr>
  </object>
</asl>

Thank you hegemonkhan, I will dive into it
