TWIGZ Inventory File ("default.inv"):
When the TWIGZ Engine is loaded the "default.inv" (Default Inventory file) is loaded into memory. Below is the structure of the "default.inv" file:

3 "Stick" "Rock" "Key" 40 1 19 0 0 0 0 0 0 207 205 0 0 0 0 0 0 0 0 0 0

The first number is the Total Number of Inventory Items, the next three items are the Names for the items, following that are the Pixel Maps for all the inventory items.

How can I create my own default inventory file?:
All you need is a ".gif" file placed in the "TWIGZ SDK\Gif" folder (Note: The ".gif" file must adhere to the GLOBAL PALETTE). Below is a sample default inventory file:

Once you have placed you image file in the "TWIGZ SDK\Gif" folder simply run the "Inventory.exe" file found in your TWIGZ SDK folder and follow the on-screen instructions.

TWIGZ Inventory Verb Files (".ivb"):
Whenever an inventory object is selected to use on an object, with an object, or just to be interacted with, the Inventory Verb file for that room is accessed. Inventory Verb files are near identical to regular Verb files with the addition of one variable. Below is an example of a simple Inventory Verb file:

"Give" 3 4001,4002,0,0,"How am i going to do that?",0 4002,3001,0,0,"He probably doesn't want a rock.",0 0,0,0,0,"No!",0 "Open" 1 0,0,0,0,"I can't open that",0 "Close" 1 0,0,0,0,"I can't close that",0 "Pick Up" 2 4001,4001,0,0,"That's a nice stick I picked up.",0 0,0,0,0,"I can't pick that up",0 "Look At" 1 0,0,0,0,"That's a nice thing",0 "Talk To" 1 0,0,0,0,"I really don't want to talk right now",0 "Use" 2 4001,5,0,0,"Put the stick in there?~Yeah, you'd want~to see that!",0 0,0,0,0,"I don't think I should",0 "Push" 1 0,0,0,0,"Not right now",0 "Pull" 1 0,0,0,0,"No pulling for me right now",0

The ".ivb" file is separated into verbs. Each verb name in quotation marks represents the start of the data for that verb. After each verb name is the total number of statements for that verb. Following that is the list of all the text that will be said by the ego (we call these lines "statements"). Any statement that starts with all zeros, like the one below, is the Default Statement for that verb.

Below is an example of a Default Statement:

0,0,0,0,"No pulling for me right now",0

What do all those numbers mean?:
Each "statement" is preceded by three (4) numbers and then followed by another. A verb statement looks like this:

ID1, ID2, Bin Variable, Bin Var Required Status, "Text", Script Number

ID1 represents the Inventory Object ID, ID2 represents the other object that the inventory object is to be used with (this number can be from 1 to 5000, it can be an object, an actor or another inventory item). The Bin Variable, Bin Var Required Status, and Script Number work the same as for a regular verb file.

Note There is no Conversation Number added on for "Talk To" statements, YOU CANNOT START A CONVERSATION WITH YOU INVENTORY! Also note ther are NO "Walk To" statements at the end of this file.

If all criteria are not met then the Ego simply says the default statement.

Note: Two unique IDs can only be used when dealing with the verbs: Give & Use. If you want to make the actor say something when he, for example, tries to open inventory object 4001 then you must make ID1 and ID2 both 4001.

How do I create an Inventory Verb File?
All inventory verb files can be written in your favorite, simple, MS-DOS text editor (Windows Notepad works fine). Just make sure there are no extra spaces (unless they are in between quotation marks) between the commas separating the different parts of a statement or at the end of a statement. When you are finished save this as a ".ivb" file in your "TWIGZ SDK\IVerbs" (thats "I VERBS," its hard to see) folder. You can do this from notepad by going to File, Save As, Choosing "All Files" from the "Save as type" drop-down menu. And naming the file "roomnumber.vrb" so if your room is room number 5, then save the file as "5.ivb"
