How to Add Properties to Stacksmith
There are 3 steps involved in adding a new persistent property to an existing object in Stacksmith (usually implemented as an object that is a subclass of
CConcreteObject or one of its subclasses):
- Find the CConcreteObject-conforming C++ class that implements the object to which you want to add a property.
- Define a C++ instance variable on the object to hold the data at runtime. Write a setter for it that calls IncrementChangeCount() to make sure any change to that property gets saved. Find the
LoadPropertiesFromElement()method and add code to load the property from the file, and add code to write the property back out again to the
- Add code that makes the property accessible to scripts to
SetValueForPropertyNamed(), keying off the (case-insensitive!) property name for scripts. You will also want to add code to log the property’s value to
DumpProperties()as an aid when debugging.
