Here, our ``ADD_SIGNAL`` macro can be a single call first taking the
signals name, then having pairs of the type specifying the parameter name and
the value of each parameter we'll send along with this signal.
Here, our ``ADD_SIGNAL`` macro can be a single call with a ``MethodInfo`` argument.
``MethodInfo``'s first parameter will be the signal's name, and its remaining parameters
are ``PropertyInfo`` types which describe the essentials of each of the method's parameters.
``PropertyInfo`` parameters are defined with the data type of the parameter, and then the name
that the parameter will have by default.
So here, we add a signal, with a ``MethodInfo`` which names the signal "position_changed". The
``PropertyInfo`` parameters describe two esential arguments, one of type ``Object``, the other
of type ``Vector2``, respectively named "node" and "new_pos".
Next, we'll need to change our ``_process`` method:
