How do I shorten sine waves

Help and Feedback Scripting Support
#1

So I have this very simple script, which just moves a part up and down in a linear pattern, kinda like hovering. My problem however, is that it goes too far up and too far down (as shown in the video). I am wanting to make it move about half or less than half as far as it is currently, but I don’t understand math very well, and can’t figure out how to shorten the sine waves. I have searched all over the forums for solutions but couldn’t find anything, so anything helps.

Here is my code:

local part = script.Parent
local startpos = part.Position

while (true) do
	wait()
	part.Position = startpos + Vector3.new(0,math.sin(tick()),0)
end

try Vector3.new(0,math.sin(tick())/2,0)
Dividing the result of math.sin will result in a shorter distance traveled

To add onto the above reply:

  • dividing the result of math.sin() by a number >1 will lower the distance travelled
  • multiplying it by a number >1 will increase the distance travelled

Similarly

  • dividing the tick() by >1 will make the wave go slower
  • multiplying it by >1 will make it go faster

You can experiment with it on desmos by adjusting the m and n sliders: Graphing Calculator
(see what happens when you change n from 1 to 2, like the previous reply suggested)

Thank you for the explanation! This helped me understand it better
