Are there any curves in Roblox Studio?

[young agate]

I need a curve in Roblox Studio that I will use position parts based on it.If there is no curve instance in Roblox Studio, is there a way to do this mathematically?
So let me explain:
-I need something that allows me to position parts using a script, those parts following the curve
-This thing will be a prototype for something(it is a secret)
-I also want to adjust the curve's length using a script
-It can also be mathematical if there isn't something like this already in the studio(I think trigonometric functions might help, but aren't those for triangles?)

I think u can just use sin and cos to make a curve and calculate x and y of each point in the curve using a for loop and use the points to position your parts

Yaay, thanks I will try that

Tho it may not work first try
