This page is a part of the Lua and UI Reference (Civ5).


Function.png This function is a member of Fractal.

This is a static method, invoke it with a dot.
Used to create a 2D-array of random values using [Fractal] (insert wikipedia link here) math.


Usage

Fractal Fractal.Create(int width, int height, int grain, table fractalFlags, int xExponent, int yExponent)


Returned Value

Returns an instance of Fractal.

Parameters

width: The width of the 2D array to create.
height: The height of the 2D array to create.
grain: Amount of grain to add to fractal. 0 is no grain (smooth), 7 is lots of grain (jagged).
fractalFlags: A table that holds certain additional options used in creating the fractal. See below.
xExponent: Amount of blurring to apply along X axis. 0 is no blur. 7 is high blur. Negative values sharpen?
yExponent: Amount of blurring to apply along Y axis. 0 is no blur. 7 is high blur. Negative values sharpen?


Fractal Flags

boolean FRAC_WRAP_X: Whether or not the fractal should wrap around the X axis.
boolean FRAC_POLAR: ???
