controlling a propeller's rotation speed?
hi. this have been asked many times, but i just don't seem to get the right answer.
here's the deal:
I have a circle spline that works as my control object. it has an attribute holder with custom attributes on it, a spinner, that will control my propeller's rotation speed.
then i have a point helper, positioned in the rotation axis, wich is this point helper's zero euler Z axis. then my rotor blade objects attached to the point helper, wich doesnt matter right now.
what i'm trying to achieve, is to make my propeller rotate whenever i set the spinner to something different than 0, if its like 1, it starts rotating, its -1 it rotates backwards. it doesnt really have to rotate backwards, but i believe thats the way it works. the only thing i need to have is the option to keyframe spinner values, meaning that rotation speed can be changed in realtime. so if anyone knows how to help me to achieve this, i'd be really glad.
thanks in advance :)
