Pikmin area generator file/File format

This page describes the format of the object generator files in Pikmin. These files have the file ending .gen. Generators handle the spawning of objects, such as pellets or enemies, in the levels. Each such object is spawned by a generator.

File header

Offset	Type	Description
0x0	char[4]	a 4 byte string saying v1.0, presumably the version of the format or the version of the file
0x4	float	unknown[unsure]
0x8	float	unknown[unsure]
0xC	float	unknown[unsure]
0x10	float	unknown[unsure]
0x14	uint32	an unsigned integer specifying the amount of generators in the file

Directly after the integer specifying the amount of generators follow the generators themselves. The format of each generator is explained in the following table.

Generator format

Offset	Type	Description
0x0	char[4]	Four spaces, presumably the name of the generator base that is used in all object types
0x4	char[4]	version string, usually v0.0
0x8	uint32	unknown[unsure]
0xC	uint32	unknown[unsure]
0x10	uint8[32]	32 bytes of data. unknown[unsure]
0x30	float[3]	XYZ position of object
0x3C	float[3]	unknown[unsure]
0x48	char[4]	4 byte string specifying the type of the object. Type name is reversed
0x4C	char[4]	version string
0x50	uint8[...]	Variable amount of data depending on type of object

Object types

Object name	Description
piki	Pikmin
debg	Debug object unknown[unsure]
item	Item
pelt	Pellet
work	Work object unknown[unsure]
plnt	Plant
mpar	Map Parts
teki	Enemies
boss	Boss
mobj	Map object
navi	unknown[unsure]
actr	Actor unknown[unsure]

Data formats for each object type. Offsets are relative to the end of the general generator data, see above for the generator format.

"item" format

Offset	Type	Description
0x00	uint32	String length (in the following offsets the string length will be "n")
0x04	string	Name of object
0x04+n	uint8[32]	32 bytes of data
0x24+n	uint8[32]	32 bytes of data

Todo: Parameters, other objects
