Inventory Verbs and Display Verbs - KVonGit/quest5-stuff GitHub Wiki

Before trying to modify an object's inventory or display verbs list

Always copy the existing list's contents to a new list in place of itself, like this:

object.displayverbs = ListExclude(object.displayverbs,"")

If you don't do that before attempting to modify a default list, you will see this error message:

Error running script: Cannot modify the contents of this list as it is defined by an inherited type. Clone it before attempting to modify.

Once you have done that

You can add to the list with list add or remove with list remove.

To add something to an object's list:

Display Verbs (displayed when object is in your location, but not held)

list add (object.displayverbs, "Foo")

Inventory Verbs (displayed when object is held (this includes objects which are inside of objects you are carrying))

list add (object.inventoryverbs, "Bar")

Removing stuff:

list remove (object.displayverbs, "Foo")

list remove (object.inventoryverbs, "Bar")

Let's say you have a weapon, which can be equipped or unequipped.

In the script for equip:

firsttime{
  this.inventoryverbs = ListExclude(this.inventoryverbs,"")
}
if(not ListContains(this.inventoryverbs, "Unequip")){
  list add(this.inventoryverbs, "Unequip")
}
if(ListContains(this.inventoryverbs,"Equip")){
  list remove(this.inventoryverbs,"Equip")
}

In the script for unequip:

firsttime{
  this.inventoryverbs = ListExclude(this.inventoryverbs,"")
}
if(not ListContains(this.inventoryverbs, "Equip")){
  list add(this.inventoryverbs, "Equip")
}
if(ListContains(this.inventoryverbs,"Unequip")){
  list remove(this.inventoryverbs,"Unequip")
}
