Project X/Scheme file

(Up to Project X)

A scheme file has scheme flags affecting general game behavior and contains one or more weapon tables. After this, attached files and scripts follow. A list of libraries can be found before the attached scheme file.

The data types are in C# notation.

Header

The header provides general information about the scheme file details.

Offset	Size	Type	Description	Default value	Remarks
0	12	raw string	Identification	"SCHM OF WAPX"	This string is not prefixed with an integer and also does not contain a terminating postfix.
12	4	int	Version	0x0000000A

Scheme Flags

Scheme flags affect the general game behavior and are set as a group of 1-byte booleans.

Offset	Size	Type	Description	Default value	Remarks
16	1	bool	Cyclic Maps	0x00
17	1	bool	Underwater Jetpack	0x00
18	1	bool	Underwater Rope	0x00
19	1	bool	Unused	0x00
20	1	bool	Unused	0x00
21	1	bool	Unused	0x00
22	1	bool	Unused	0x00
23	1	bool	Unused	0x00
24	1	bool	Unused	0x00
25	1	bool	Unused	0x00
26	1	bool	Unused	0x00
27	1	bool	Shoot doesn't end turn	0x00
28	1	bool	No loss of control	0x00
29	1	bool	Firing pauses timer	0x01
30	1	bool	Allow WA scheme to tweak power	0x01

Weapon Tables

A scheme must contain at least 1 weapon table. Theoretically, up to 2^16 tables are possible. Each weapon table consists of 71 weapon entries (of which several are utilites and not literally "weapons"). The header tells how many weapon tables are available in the file, following one after another. Information on about how to parse a single weapon can be found here.

Offset	Size	Type	Description	Default value	Remarks
31	4	int	Table Count	0x01	Cannot be zero.
35 (first)	diff.	Weapon	Weapon of table		Repeated 71 times for each table.

Placeholder

The meaning of the following integer is most possibly a counter for a type of structure not implemented in the most recent Project X version. Thus, it is always zero.

Offset	Size	Type	Description	Default value	Remarks
diff.	4	int	Unknown Structure Count	0x00000000	Always zero.

Files

Attached files follow. Again, an integer specifies how many files are attached.

Offset	Size	Type	Description	Default value	Remarks
diff.	4	int	File Count

A single attached file is described with the following structure, which of course repeats for the number of files in the scheme:

Offset	Size	Type	Description	Default value	Remarks
diff.	diff.	string	Name
diff.	4	int	Length		The length of the file data in bytes following without this describing structure.
diff.	s. Length	int	Data		The raw bytes of the attached file.

Scripts

Scripts are attached to the scheme as strings with an additional name. As you might have guessed, an integer reveals how many of the scripts are found.

Offset	Size	Type	Description	Default value	Remarks
diff.	4	int	Script Count

For each script, the following structure follows:

Offset	Size	Type	Description	Default value	Remarks
diff.	diff.	string	Name
diff.	diff.	string	Script contents		The source code of the script.

Libraries

Libraries can be "attached" to a scheme. However, the library file contents are of course not copied into the scheme file, but referenced with the library file name, and so only the library file names are listed. Surprisingly, we have an integer giving the number of attached libraries (or, to say, the number of library file name strings following).

Offset	Size	Type	Description	Default value	Remarks
diff.	4	int	Library Count

Repeated the times Library Count gave you:

Offset	Size	Type	Description	Default value	Remarks
diff.	diff.	string	Library File Name		This is the file name including the extension ".pxl".

Scheme

Optionally, a typical WSC scheme can be included in the Project X scheme. A 1-byte boolean tells you if this is the case.

Offset	Size	Type	Description	Default value	Remarks
diff.	1	byte	Scheme attached flag		If true, the following details about the scheme file exist.
diff.	4	int	Length		Length of data in bytes without this descriptive header
diff.	s. Length	byte[]	Data
diff.	diff.	string	Name		Original file name of the scheme including the .wsc extension.
