Man thanks for the response, i was able to figure out what you did and apply it to mine and its working great, like i said im pretty new to c4d and was always kind of wondering what the custom shader was for in the effectors. Makes perfect sense now. Thanks again.

Koby.
I was just curious as to the purpose of the “1-Math.cos”..doesnt that basically leave you with a Math.sin?
-
you could also try this..
Math.abs(Math.sin(time)*100)

Im not sure how to alter your code to work but if its taking too much time to figure out i would just keyframe the fade up and back down over 3 seconds then “loopOut(“cycle”)” to get them to loop continuously.

It also looks to me like your just defining variables without actually executing them for anything, Your saying what startVal and end equals but not putting them to use, and actually giving the same variable different values. Im not an expression pro at all or anything so this could be a method im not aware of but thats the main problem i can see with the code.

Man i tried the connect but i didnt make them editable first. Thats what i was lookin for though thanks.

Well you could write an if/else statement with a checkbox…but an easier and just as effective way would be to just expression pickwhip your values to an expression slider…then just keyframe the slider.
if you dont know slider is under. “effect”,”expression controls” “Slider Control”. Then highlight your “340” and whip it to the slider value.

i actually had to ask that question myself a while back and played with some really complex scripts on a stroke to get it to work…but then came to find out its as simple as using the “Beam” effect. Just expression pickwhip your end points of the beam to the position of your objects and your set.

That sounds like it would help in the future, only problem i can see with it now without testing it out is since for ex. my sine wave now is divided by an exp curve…if i set the time to turn on a few seconds down the timeline my sine wave could be almost completely decayed (depending on how fast i set it to decay) by the time it turns on, thats why i was wondering if there was a way to make it look at the time it turns on and subtract that amount of frames so its as if it started at 0.
My other concern is since this is my first time using xPresso, and i didnt really follow tutorials just sort of experimented, my nodes are a mess and im not sure how id implement your technique in with this pipeline without changing the results because i have it animate exactly how i want, ill add a pic of it.
…basically i have the word “Battle” (i couldnt use mograph type cause its a custom font so each letter is its own extruded object) So the “movement Y” on the end of the pipeline is the extrusion height, and i have it start with the “B” and sequentially animate up in sort of a “wave” look…a lot of those math nodes are mostly multiplying and/or dividing the freq and amp of the sine waves and exp curve, so they may look redundant but as i said this was kind of an experiment.
Sorry for the Novel but after all that if you know how i could implement your idea with my flow that would be great thanks!.

ahhh the beam effect, ive actually attempted this before and ive spent hours tweaking linear scale to position ratios and rotation to position..blah blah etc etc and always ended up with a crude version of what im trying to do…and was constantly thinking “if only i had 2 anchor points on this shape layer”….beam effect never even crossed my mind! thanks, little annoyed of how easy of a fix that was though lol.
