Bobbing in Water REDUX REDUX
The expressions I am using..
on positionxAmp = 3; //height of undulations (pixels)
xFreq = .3; //undulations per second
xSpeed = 150; //speed of wave (pixels per second)wl = xSpeed/xFreq; //wavelength (pixels)
phaseOffset = ((position[0]%wl)/wl)*2*Math.PI;
y = xAmp*Math.sin(2*Math.PI*xFreq*time + phaseOffset);//–NEW
swayAmp = 100; //amplitude of sway
swayFreq = .25; //frequency of sway
x = swayAmp * Math.sin(time * swayFreq);//—–
value + [x,y]on rotation
xFreq = .3; //undulations per second
xSpeed = 150; //speed of wave (pixels per second)
damping = 15; //undulation damping factorwl = xSpeed/xFreq; //wavelength (pixels)
phaseOffset = ((position[0]%wl)/wl)*2*Math.PI;
theta = Math.atan(Math.cos(2*Math.PI*xFreq*time + phaseOffset));
radiansToDegrees(theta)/damping;Is there any way to make the upward motion be faster than the downward motion? Say 50% faster?
Any help is much appreciated.

try changing swayFrq to:
swayFreq = xFreq * 2;
that should link the timing of your vertical movement to your horizontal movement, but make the hozizontal undulation frequency 2x as long…

Thanks Kevin, but what I am trying to do is have the downward motion of the object take twice as long as the upward motion.
I need my object to siiiiiink down and then POP upwards as well as rotate and sway as it is now. -
sorry, i misunderstood (or misread)…
replace swayFreq with this:
swayFreq = xFreq / 2;

scrap that.
i totally misread your post… i understand what you are looking for now. let me think about this for while…
