Hello,
I am trying to code the behavior of an object moving a certain distance from its present location along the X axis. The distance the object will travel is a geometric random variable with a mean of 15. How can I generate this number using MEL math and random number generators?

hi there,
could it be something like this?
your object.translateX=rand(1,15);

Unfortunately that would give a equal likelihood of any number between 1 and 15. A geometric distribution needs to center around a mean of 15 with 15 being the most likely. However, this is not a gaussian equation. Thank you for replying thought.
