That was super helpful.
I've been wanting to learn how that works.

Thanks Hannu.

zivko, for cannon you need to have two psystems, first one is the same normal emitter system with "die on hit" enabled and another one is a reactor system.

great tutorial!
what to do if I want to make a reverse Version? I mean,
the Balls should explose after the contact with Susane?!

carlinhos, I haven't tried it yet, but weight painting seems to be possible. http://wiki.blender.org/index.php/Manual/Explode_Modifier

Very nice tutorial, thanks!

It wonder if it is possible to destroy an object only into its unconnected parts.
Great would be a feature which allows demolition only along seams.

Oh man.. I just came back from a small one day trip and what do I see. This news here on BlenderNation and so many nice comments in both here and Blender Artists. What a way to end the long day. Thank you all very much, especially you Alex for publishing this!

Jahka! Glad to hear your word on this (these?) one too. Before I made any of these, I did my best on researching the details I was going to explain. That cache thing was something unexpected while recording and I decided to leave it in the video, since someone else might have the same problem. Sorry about the word "bug" though. :) I'll try to add a correction in the video description as soon as I can, maybe even in to the video itself. I'm very glad to hear that you are still working on the system. Wonderful stuff you've coded there already!

Now I'm off to shower, have a nice weekend you all!

ps. I hope this comment comes through, and only once. I've been having some difficulties with the spam blocker here lately.

Jose Sanchez: This is a a feature, but I do see the need for a "use object center" option and will be adding it soon :) but untill that just set the objects to global origin (0,0,0).

And oh yea, the "possible baking bug" described in the tutorial is not actually a bug. It's just that after the cannonball particles are baked their collisions are not calculated dynamically anymore, so the reactor particles don't know that there are any collisions by the target particles. To get the dynamic collisions (which create the events that reactor particles can react to) you need to re-calculate the target particles too.

A very nice tutorial on all other accounts! :)
