Re: Is the Code for My Age Available?

Whoopsy--guess I shouldn't have skimmed the details there, thanks for catching me. Ah, and instructions right in your tutorial too. Perfecto!
First, a prp file is basically a large array of objects. PyPRP can assemble and disassemble these lists.
PyPRP also has a large number of classes for each object in a prp file.
These classes share the same behaviour for a large part:
Code: Select all
### PSEUDOCODE ###
class plClassName:
def __init__(self,name,type=0x0006): # the 0x0006 is an example object type nr, these are different for each object
#initializes the object by inserting default variables
def read(self,stream):
# Read in the object-specific data into variables
def write(self,stream):
# Write out the variables into object-specific data
def export_obj(self,obj): # form can vary
# Reads in blender data from the blender object (the obj variable) and fills in the prp objectg fields based on that data
def import_obj(self,obj): # form can vary
# Reads in the prp-specific variables, and uses them to set the correct settings on the blender objects
Note, that this is only basic structure, not all classes have export/import functions, as sometimes variables are set or read externally.
Pyprp has a resource manager that manages creation of each object, and makes them findable. That one also handles storage and reading.
Another function of pyprp's resource manager is to handle basic blender interpretation. From the code in the export function in the resource manager, the objects are made, or object creation is delegated.
It basically follows a list of all blender objects, and created prp objects according to different settings on the blender objects.
Hope this helps...
I'll certainly have a use for some of this information in my explanation of the files underlying the Age, although some of it is over my head at the moment I'm afraid. Heh, I'd ask you to explain, but I have a feeling that it might result in a kind of recursive effect where I have more and more questions the more you expand my limited knowledge. And I wouldn't want to pester you too much with questions when I haven't even looked for the answers myself. 
Thanks for posting that tutorial. 
. And with regards to the PRP documentation, Cyan asked us a long time ago to stop posting that information out in the public, so although the COBBS docs are horribly outdated (and in some cases, horribly wrong/incomplete/unhelpful/etc), all of our newer stuff is held private among the major tool devs right now.
