1st necessity of SL

Ever since I noticed that many sims contain 1000's of wonderful objects with fancy effects and 1000's active scripts that use valuable simresources while no-one is around to enjoy it, I wanted to script something simple to offload those resources and give the visitor a better experience.

That's why I made this little script: '1st necessity of SL' that could and should be used in any project that doesn't need to be active all the time.

We are building a better place, together :)

<lsl> // Improve SecondLife's performance! // Start with your own(ned) modifyable scripts/objects. // // This will disable your rootprim's script(s) when no-one is around to use/admire it // thus stop wasting valuable sim-resources // // Measured script time is 0.002 ms on average. // // - don't use it for rental stuff or sorts, not everything is suitable - // // Free to use, please use it. Improvements are welcome. // // Thank you Norton Burns for the testing and feedback :) // // Beer Dailey // // Don't reset this script or take it back in inventory when you're not within the set distance // or you'll get unpredictable results !! // // modify below to suit your needs
