How do I implement the wavelength into this?
minVal = 5.0 -- (the wave will never go below this value)
maxVal = 30.0 -- (the wave will never go above this value)
clearlistener()
delete objects
-- /* -- -- -- BOUNCE (w/ Options) -- -- --*/
for i = 0 to 100 do
(
waveLength = (units.decodevalue "10.0cm")
variable = sin(i as float/.1)
range = maxVal-minVal
val = (if variable > 0 then variable else variable*(-1))*range
val += minVal
obj = box pos:[i*2,0,(val)] width:2 height:2 length:2 wirecolor:red
)
EDIT: My desired goal is to have the distance between each sin wave be controlled/equal to the supplied wavelength.
EDIT: Nothing to see here completely got lost while trying to figure out the issue.
Ignore my previous post. You want the width of the sine wave equal to the wavelength?

Eric,
Yeah that is exactly what I’m after.
I want the length between each wave to be equal to the supplied wavelength.
Often I completely misunderstand people’s questions. But I can’t see how this time. I hope this is what you need:
minVal = 5.0 -- (the wave will never go below this value)
maxVal = 30.0 -- (the wave will never go above this value)
waveLength = units.decodeValue "32cm"
count = wavelength*2
ratio = (360./count)
clearlistener()
delete objects
-- /* -- -- -- BOUNCE (w/ Options) -- -- --*/
for i = 0 to count do
(
degs = (i*2*ratio)
variable = sin(degs)
range = maxVal-minVal
val = (if variable > 0 then variable else variable*(-1))*range
val += minVal
obj = box pos:[i*2,0,(val)] width:2 height:2 length:2 wirecolor:(if mod degs 90 == 0 then green else red)
)
Regards,
Eugenio

is it what you are looking for?
Yeah that is exactly what I’m after. Thanks guys for the quick help and responses.
I couldn’t wrap my head around why the wavelength was not working the way i thought it would.
Thanks
How do I adjust the decrease or increase in the given wave using DenisT code? Do I adjust the steping? So the wave decreased in amplitude and length over time.
See code for example.
-- /* -- -- -- SINE Simple (w/ Increase) -- -- --*/
for i = 1 to 600 do
(
val = (sin(i)*cos(i))*i*freq
obj = box pos:[i*2,0,(val)] width:2 height:2 length:2 wirecolor:red
)
there are actually two parameters who change the X-distribution: waveLength and num (number of point on the wave).
if you change the number of points it will change the step (distance between points along X axis)
Incrementally adjust them.
So over time the waves in general decrease or increase. *like the stock market
I got it going upward!..no wavelength decay yet.
