lib3ddevil1
|
||||||
|
A C library for handling Devil May Cry 1 HD Collection PC file formats.
|
||||||
|
These formats are little endian.
|
||||||
|
|
||||||
|
Design/Restrictions
|
||||||
|
Library functions do not:
|
||||||
|
- allocate memory on the heap
|
||||||
|
- operate on files
|
||||||
|
- convert endianness
|
||||||
|
|
||||||
|
Pseudo-Namespaces
|
||||||
|
Library functions are callable through a struct of function pointers.
|
||||||
|
For example:
|
||||||
|
// Print header of a .pld file.
|
||||||
|
DEVIL1PLD.printheader(...);
|
||||||
|
|
||||||
|
// Print header of a texture pack.
|
||||||
|
DEVIL1TEX.printheader(...);
|
||||||
|
|
||||||
|
// Print header of a mesh pack.
|
||||||
|
DEVIL1GEO.printheader(...);

devil1pld.h / devil1pld.c
|
||||||
|
Handles .pld files.
|
||||||
|
|
||||||
|
File Format
|
||||||
|
PLDs are simple packages of different files, and do not contain a table
|
||||||
|
of contents. The header consists only of the number of files packaged
|
||||||
|
and the offsets from the beginning of the .pld that marks the starting
|
||||||
|
location of the file.
|
||||||
|
|
||||||
|
Functions
|
||||||
|
All functions are static but exposed by a function pointer in a constant
|
||||||
|
struct called DEVIL1PLD. For example, clients call functions using
|
||||||
|
DEVIL1PLD.getheader(..., ...);
|
||||||
|
|
||||||
|
bool getheader(struct PldHeader*, const char*);
|
||||||
|
Places file header into the struct pointed at by the first parameter
|
||||||
|
from the information given in by the second parameter.
|
||||||
|
|
||||||
|
inputs: pointer to a struct, pointer to file data
|
||||||
|
Neither parameter should be NULL.
|
||||||
|
|
||||||
|
output: true or false, whether or not operation succeeds or fails.
|
||||||
|
Will return false if one or both of the parameters are NULL
|
||||||
|
pointers.
|
||||||
|
Will return false if the attribute numOffset is less than 0-
|
||||||
|
i.e file is not valid.
|
||||||
|
|
||||||
|
int sizeofsector(struct PldHeader*, unsigned int i, unsigned int max);
|
||||||
|
Returns the size of the i-th file packed in the pld.
|
||||||
|
|
||||||
|
inputs: pointer to a struct, i-th element in pld, file size
|
||||||
|
|
||||||
|
output: (-1), [0, maximum value of int)
|
||||||
|
-1 indicates an invalid input.
|
||||||
|
|
||||||
|
void printheader(struct PldHeader*);
|
||||||
|
Shows contents of a PLD header in standard output.
|
||||||
|
|
||||||
|
inputs: pointer of a struct
|
||||||
|
|
||||||
|
Example logic to iterate through a .pld
|
||||||
|
{
|
||||||
|
...
|
||||||
|
// Get information about the file
|
||||||
|
struct PldHeader h;

lib3ddevil1/bindings
|
||||||
|
Python interface to C library functions of lib3ddevil1.
|
||||||
|
|
||||||
|
This component uses ctypes thus it must access a compiled .so file (internally
|
||||||
|
a .dll for Windows). The .so may be located in the top level of the library
|
||||||
|
directory or any directory in the environment variable's path.
|
||||||
|
|
||||||
|
Note that there are two categories of objects in each python interface. One is
|
||||||
|
derived from ctypes.Structure, and the other is a pythonic object. The former
|
||||||
|
is for internal use and requires knowledge of both python, C, and ctypes. The
|
||||||
|
latter is to be used by python users.
|

unsigned int);
|
||||||
|
Retrieves i-th instance of a TextureBatch from a buffer.
|
||||||
|
|
||||||
|
input:
|
||||||
|
Pointer to a pointer of TextureBatch.
|
||||||
|
This is pass by reference of a pointer to the function.
|
||||||
|
The pointer to a TextureBatch can be NULL and will be set to
|
||||||
|
point to a region in the const char*.
|
||||||
|
|
||||||
|
unsigned int, the i-th instance of a TextureBatch in the
|
||||||
|
const char*.
|
||||||
|
|
||||||
|
const char*, the buffer containing the whole texture pack file.
|
||||||
|
|
||||||
|
unsigned int, the size of the buffer.
|
||||||
|
|
||||||
|
output:
|
||||||
|
true on success.
|
||||||
|
|
||||||
|
false when failing checks against segmentation faults.
|
||||||
|
When const char* is NULL.
|
||||||
|
|
||||||
|
When the location of the Texture Batch will exceed the size
|
||||||
|
of the buffer.

bool gettextures(struct Texture*,

|

|
Retrieves textures of the i-th batch from a buffer.
|

|
|

|
input:
|

Pointer to Texture. This can be an array of Textures.
|

|
This parameter can not be NULL.
|

unsigned int, the i-th instance the TextureBatch containing

the files.

const char*, the buffer containing the whole texture pack file.

unsigned int, size of the buffer.

output:

true on success.

false when failing checks against segmentation faults.

Example logic to interact with all textures:

// Need to know how many batches are in the package.
|
||||||
|
struct TexturePack *p = (struct TexturePack*)filedata;
|
||||||
|
|
||||||

// Need to know about each batch in the package.
|
||||||
|
struct TextureBatchDescriptor *d = NULL;

||||||
|
|
||||||
|
struct Texture *t = NULL;
|
||||||
|
|
||||||
|
unsigned int i;
|
||||||
|
for (i = 0; i < p -> batchNumber; i++) {
|
||||||
|
DEVIL1TEX.getbatchdesc(&d, i, filedata, filesize);
|
||||||
|
|
||||||
|
// Batch descriptor tells how many textures are in the batch.
|
||||||
|
t = (struct Texture*)
|
||||||
|
malloc(sizeof(struct Texture) * (d -> texNumber));
|
||||||
|
DEVIL1TEX.gettextures(t, i, filedata, filesize);
|
||||||
|
|
||||||
|
// There are now textures in 't'.
|
||||||
|
for (j = 0; j < d -> texNumber; j++) {
|
||||||
|
// Do whatever you want with however many textures there are.
|
||||||
|
}
|
||||||
|
free(t);
