<div dir="ltr"><div>Yes, LSL makes things difficult. What is the general feeling on compatibility vs. improvements when it comes to scripting? Would having both a "100% compatible" and a completely separate, and completely different, "new scripting model" make sense?</div>
<div> </div>
<div>One thing that a new model could explore are some simple declarative triggers and actions for things like door opening, etc. In it's simplest form, the (possibly external) script would call an API to associate something like an llSetPrimitaveParams argument list with an event like touch. The sim would automatically apply those changes when the event occurs, no further interaction with the script would be needed. Look at how events and animations work in WPF or Silverlight for an example of what I mean.</div>
<div> </div>
<div>One big long term advantage of going down a path like this is improved security. Moving untrusted code execution out of the core simulation process would be a really good thing. Pushing declarative trigger/action pairs back into the secure process is much safer.</div>
