Perlin noise help

Help and Feedback Scripting Support
#1

i was planning on making a remake of terraria, i was researching Perlin noise and came across this, i am confused about where it says
If you leave arguments out, they will be interpreted as zero, so math.noise(1.158) is equivalent to math.noise(1.158, 0, 0) and math.noise(1.158, 5.723) is equivalent to math.noise(1.158, 5.723, 0)

does this mean that you can change -1 and 1 to -5 and 5, to change the terraain generation to what you want, also, has anyone got anthing on cutting a slice out of the Noise map to make a 2D generated terrain?

Well this is saying that if you don’t specify the other arguments then…
math.noise(1.158) == math.noise(1.158, 0, 0)
Notice how 0, 0 wasn’t specified on the left side, but will still “be there” even if you didn’t specify.

so it just automatically fills in the blanks with a sort of template?

You can think about it that way. It’s more of a “default value” thing.

okay, how would you make it so you can get a slice out of it, to get a 2d side on terrain?
