In a couple of places recently (Vidal Tripsa and Crap Mariner come to mind, but darned if I can find the actual postings depite long milliseconds of searching) I’ve seen references to causing builds to blow up by setting them physical and temporary, and then delinking them.
The other evening amazing small-stuff maker PatriciaAnne (see her Lilliton for instance) IMd me asking for a script to make something explode, and I jumped at the chance to say “sure” and thus commit myself to figuring out the details and writing a script to do that myself.
I eventually wrote it, and gave it to PatriciaAnne, and also to the world on the Second Life wiki. And now we have a demo!
Here is the thing to be blown up: a popular freebie house, rezzed on a nice seacliff somewhere in Shengri La:
We insert the script, utter the magic words, and ka-boom:
Debris flying everywhere!
And here is the result:
(Some number of seconds later the debris all vanishes automatically; no need for cleanup work…)
