Here's an introductory blend scene for those wishing to learn about rigid bodies!

After opening the file, hit P on the keyboard to run a simulation. Try adjusting the mass, location, and size of the "destructor" cube to learn how these settings affect the simulation.

You can also create completely new structures from the building blocks, just make sure to hold CTRL when moving them to keep them side by side. The only limit is your computer's RAM!

To save your simulation, make sure you're in the game engine and click "Game" and "Record Animation."

It took me a while to learn to use bullet physics properly, so I hope this will be of help to some and save them a bit of frustration.

Important Tips! To make your structures more stable, increase the Physics substeps to 5 (max). This will increase computational time.

Additionally, still in the Game Engine, go to the material panel and increase Friction. Default is 0.5, I usually stick it to 5 or 10. This will keep your objects from sliding around too easily. Max is 100.

To preview what some different settings do, you can view this video.

    Thanks for this , really helps me out , look forward to Version 2 :). is there anyway you could make a structure with 99 elements ( components) , i am hoping to get this into a game and 100 elements is its max .

    Thanks again

    What kind of structure is it that you need? It's really not that hard to generate them yourself, but if you'd like me to make you something simple I would be happy to.

    I have read your tutorial and watched the video in a more wide awake Mode , seems you are right it is very easy using this base to crop and change things to give multiple results . Thanks a bunch loving this stuff. I am just trying to create an inner structure for some Highrise Buildins , i will Hide the outer skin on impact then kick in the Keyframe result thats outputted via your system, ill post a Video of an alpha ASAP
