Since I wont have time to participate in the contest myself feel free to take stuff (or just ideas) from my blend file. See this thread in the game engine forum for more info. Werner

Brilliant stuff!!

Incredible Machine brings back sooo many interesting memories. I loved that game, and was looking for something similar, but never thought of building one with Blender. I'm going to definitely give this one a go.

The .blend files might not work the same on all platforms/Blender builds, but CPU speed shouldn't matter.
Linux, Windows, Mac OS X all might have slightly different optimizations which impact the overall behaviour.
With more experience you can improve the reliability of the movement.

You can bake IPO's or generate a movie if you like, but indeed a .blend or other method to re-create should be provided (including the platform used).

Yes, you can do whatever you like, you can use python, and you can also use multiple scenes.

Good luck!

Hi. I have downloaded an example which Appolonius made and gave link at continousphisics forum. the machine havent worked properly, when sphere should puch domino, sphere dont touch domino.

And this is the problem – machine which works on someones computer, can not work on faster/slowler computer, when next move depends only of touch of other object, this obj can not touch other on other computer.

So how about it? Maybe recording the movement? Of course blends must be send.

How about using python?

Big machines can be build of many dynamic objects, so can machine be done in more then one scene, whcih will change after each part?

This is not a speed issue, the scaling of the objects is way too large: 20 ~ 40 meters/units.

It will be fixed, but the mousetrap/movie is just a quick example to give some direction.
Thanks,
Erwin

@moxab
Also, further into the thread, there are other versions available that address the speed issue.

@moxab
you can go to the Game menu located on the topmost menubar and deselect the "Show Framerate and Profile" option.

This looks like a contest for me! Marty, Those are the coolest videos! Thats definetly good inspiration.

in the .blend file for fobsta's "mousetrap", the ball seems to move way to slow. Is there a way to speed up the engine?

There will be a special section in the Wiki, similar to the previous PSP contest. So contestants can just edit their own entry, until the deadline (1st march) is reached.

This wiki page/registration will be available 'when its done' or 'really soon', and its link will be added here:
http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=775

Don't forget to try out the latest Blender 2.43 preview and physics demos, they might provide a good starting point:

Enjoy and please create some fun machineries!
