You will need to have the MFM ready to build from source to do this. Follow the instructions at Cloning from Github if you have not done so yet.

This tutorial highlights making a density regulating element which regulates nearby density based on some configurable parameters.

First, copy:

MFMv2/src/elements/include/Element_Template.h

to

MFMv2/src/elements/include/Element_Creg.h

In order for the compiler to be able to create a compiled version of this Element, you will need to create a small C++ file which associates with it. Create the file:

MFMv2/src/elements/src/Element_Creg.h

Add the line:

#include "Element_Creg.h"

to the top. This compiles the header in its entirety.

Many things in the template need to be renamed to reflect the new Element. There are comments throughout the C++ template labeled:

<<TEMPLATE>>
