== Learn Basic lsl Secondlife Scripting in 2 hours ==


I created these videos (Hosted on YouTube) with the purpose of explaining to a newcomer to lsl in a very basic way how to ''compile'' a [[script]] and why it looks and reads the way it does. They are not meant to taken as a definitive guide and so far only cover a few very simple basics. For those with no previous programming experience but a desire to create ''living'' objects in Second Life, take a look at these to get a first grasp on the basic structure of a script and some of its components.
I will be continuing the series as time goes on. My apologies for the poor quality and extraordinary dullness of my voice. Feel free to comment on the discussion page.
'''[[Getting_started_with_LSL|This internal wiki page is a good ''written'' place to start too]]''' (I didn't know it existed until two days after making the first of these videos. Grumble grumble)
'''[http://www.youtube.com/user/EddyFragment#play/user/A1B5507CA136EA91 This is the whole 2 hour playlist hosted on YouTube URL]'''
'''The individual parts hosted on YouTube are as follows'''
