Python 3 library for modifying and creating Halo content based on the Supyr_Struct Library.

Reclaimer

What is this repository for?

• Reclaimer is a library of supyr_struct structure descriptors and tag definitions for creating and modifying data files for video games utilizing the Blam engine. These descriptors and definitions are currently limited to Halo 1(xbox, custom edition, and the community made "open sauce" variant) with some support for Stubbs the Zombie. There are plans to branch into Halo 2, though for now the "he2k" sub-module is just a placeholder. Some of the tag definitions have an accompanying object class with methods for manipulating the tag(recalculating inertial matrices in physics tags for example).

Installing

First install any version of Python 3(The newest version is recommended).

There are two ways to install reclaimer from this point:

• Open a command prompt and execute pip install reclaimer

or

• Extract a copy of the repository into a directory titled "reclaimer".
• Move the file "setup.py" into the directory containing "reclaimer".
• Open a command prompt, navigate to the directory containing setup.py, and execute:python setup.py install
• During install, python should try to download and install supyr_struct. If it fails to, you must install that as well.

Once the install finishes, reclaimer should be ready to use.

There are currently no test cases, but you should be able to directly import any tag definition from the python interpreter, build it, give it a filepath, and serialize it as shown below:

>>> from reclaimer.hek.defs.pphy import pphy_def
>>> asdf = pphy_def.build()
>>> print(asdf)
