Coffee roaster


#1

Hi

I’m new to blender and are interested in Blender because I teach the science of Coffee. I have worked with some protein-import to illustrate for teaching but lately I have been working on a coffee roaster, since I teach coffee roasting and would like to illustrate the coffee roasting process in dynamic 3D using Blender.

I have build a very simple (if not pathetic) roaster (drum, paddles, cabinet and a single coffee bean) and I succeed in rotating the drum. I would like to be able to add (unrealistically) around 20 beans to the roaster and would like to see them being tossed around in the drum by the paddles as it simulates a roast.

I thought, that I could use the game engine and make a kind of ‘bouncing ball’. The being-roasted-coffee-beans playing the role of some balls and the rotating (!) cylinder is just a cylindrical moving ‘table’ that the ‘balls’ are bouncing in. BUT when I added the bean and started the games engine, the bean fell down due to gravity into the bottom of the roasting drum but as soon as the game simulation started, the drum stopped rotating! How can I have all the balls (coffee beans) bouncing inside the rotating drum? I must admit that I’m caught between key framing the drum and the game engine that provides the physics that I would like to operate inside the turning (key framed) drum.

Any suggestions?

I’ve added game logic to your blend to have the drum constantly rotate when you start the game engine. (I assume you are using the latest version of blender)
