This may be an obvious question, but I just can't seem to wrap my mind around it. Besides using a formula node, is it possible to initialize a variable in a while/for loop so that you can increment/decrement it to whatever you like. So far, I have simply wired the iteration variable (i) but because it is always initialized to 0 and it only increments, I do not believe I can use it. What I would like the variable to do is to increment to a max number and once it reaches it, to start decrementing to a min number and then increment again and so forth, basically I want the variable to oscillate between the two max and min values.
Thank,
