need help with rotation x,y math

[arfa]

Experiment with changing the angle increment [smaller is smoother] and the time factor [ditto] set to add it.

Keep in mind that x/y is being calculated on the fly and the more frequently this is done the more resources required. I couldn't say exactly how much but it can add up when set alongside the rest of your project.

Well, my use for it would be used for something similar to an interactive bar that can rotate objects for a certain angle.

For instance, I want all objects to rotate around the object to 30 degrees. After that, it would stop. I do hope, however, that this will not consume too many resources. A project I have in mind (haven't really started it yet) is going to play with a ton of things....I just hope I'm up for it.

Ausomeman, just change the timed angle-increment line to a user input.

Here is my final rendering. I have learnt a lot doing this and can implement some of it directly in a current work.
