1.4 LSL Key

 

Getting a Key

There are several ways to acquire the key of something:

1) Having someone supply it to you;

2) Using a native LSL function such as llGetKey, etc.

3) In your inventory, right-clicking over something and choosing "Copy Asset UUID." Note this will only work on items that you have full permissions to.

 

1.5 LSL List

 

Adding an Element to a list

There are several ways used to add an element to an existing list via prepending/appending:

myList = [new_item] + myList; Best method for Mono-LSL

myList = myList + [new_item];

myList += [new_item];

myList = (myList=[]) + myList + [new_item];

myList = myList + new_item;

myList += new_item;

myList = (myList=[]) + myList + new_item; Best method for LSO-LSL
