STD file

the std file structure(std file is the file that controls 3d bkg)

file header:
word data_count
word (the count of that statements whose second parameter is 0x1c(28))
dword address_moredata
dword address_script
dword unknown
string anm

data address(begin from 90):
dword data_address_01
dword data_address_02
......

data(which is the objects in std)(create object using "script" number in anm):
[data 0]
word std_object_id(usually same as data number)
word anm_script_id
float x
float y
float z
float width
float height
float depth
(the following statements follows the upper statements directly, and may repeat many times)
word 0(0 means a quad, 0xffff means the end  WHATISTHIS.jpg)
word 1Ch
word anm_script_id
float x
float y
float z(x y z are the position of the upper-left corner)
float width
float height(if not 0, this data will cover the width and height in anm, otherwise the program will use datas in anm)
......
word FFFF
[data 1]
......

more data(put objects that are set up in data to somewhere in the space):
[more data]
word std_object_id
word 100h
float x
float y
float z
......

script(script zone):
......
FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF

std scripts
name	number	parameters	usage
setCamForward	0600 1400	float x, float y, float z	set the camera's direction(usually(0.0f,1.0f,0.0f))
setCamFOV	0700 0C00	float angle	set the camera field
setFog	0800 1400	[byte R, byte G, byte B], byte alpha, float start_z, float end_z	create fogs with specified color and alpha in the field start_z~end_z
changeFog	0900 1C00	dword time, dword mode, [byte R, byte G, byte B], byte alpha, float start_z, float end_z	change "setFog"'s parameter by time
setCamPos	0200 1400	float x, float y, float z	set the camera's position
moveCamPos	0300 1C00	dword time, dword mode, float x, float y, float z	change "setCamPos"'s parameter by time
setCamTarget	0400 1400	float x, float y, float z	set the camera's facing target position
moveCamTarget	0500 1C00	dword time, dword mode, float x, float y, float z	change "setCamTarget"'s parameter by time
jump	0100 1000	dword bytes, dword time	jump to given bytes' address within given time pos
setFlag	0C00 0C00	dword flag	give the bkg some effect by given flag. following is in HSiFS: 1:the camera position jump left and right; 2:bkg rotates counterclockwise from 0.0f(HSiFS stage6); 3:the camera position floats up and down, facing floats left and right;
 4:bkg rotates clockwise
UNKNOWN	0D00 0C00	dword unknown	unknown
unset	1000 0C00	dword a	cooperate with ins_630 in ecl(630 in th14, 527 in th12, 441 in th10). when ins_630 is called, std will jump to ins_16(1000 0C00)(int a)
UNKNOWN	0E00 1400	dword unknown_00, dword unknown_01, dword unknown_02( dword unknown_00, dword unknown_01 in MoF)	unknown
UNKNOWN	1300 0C00	dword unknown	unknown
moveCamForward	1200 1C00	dword time, dword mode, float x, float y, float z	change "setCamForward"'s parameter by time
UNKNOWN	1100 0C00	dword unknown	used in HSiFS stage1, the parameter is 1, in which the lower half bkg twists
