ScriptFile Asset

The scriptfile asset is used on both Modern Warfare 3 and Ghosts. It is Infinity Ward's attempt at protecting their game scripts from being modified. Compared to Treyarch's scriptparsetree, the scriptfile gives away less information on identifying which game script file it originated from. All unnecessary strings have been removed and file names have even been renamed as number id's.

struct ScriptFile
{
  const char *name;
  int deflatedLen;
  int inflatedLen;
  int codeLen;
  char *data;
  char *code;
};

Data Section

The data section is a zlib compressed section that contains data used by the code section. It's compressed size is equal to deflatedSize and it's uncompressed size is equal to inflatedSize.

Code Section

The code section is the actual compiled game script code.
