42484156 (BHAV)

This resource contains the SimAntics subroutines.

Format

64 bytes
File name (null terminated)
12 bytes
(see Header Format below)
for each entry
variable
(see Entry Format below)

Header Format

WORD
Signature (0x8000 through 0x8009)
WORD
Number of instructions in subroutine
Byte
tree type (deprecated)
Byte
Number of parameters passed to the subroutine
Byte
Number of local variables used in the subroutine
Byte
Header flag (depreciated)
DWORD
Tree version number (signed integer)

Entry Format

The signature defines the structure of the each instruction.

WORD
Function/OpCode
WORD
Goto on true
WORD
Goto on false

Notes

The 1-byte Goto statements in 8001-8006 appear to use the same codes as was used in The Sims 1: *0xFD as Error

  • 0xFE as True
  • 0xFF as False.

The 2-byte Goto statements in 8007-8009 use these Goto codes:

  • 0xFFFC as Error
  • 0xFFFD as True
  • 0xFFFE as False.

The 8007-8009 formats can contain more than 256 seperate instructions, thus the use of 2-byte Goto statements.

Notes

Number of each signature type (0x8000 - 0x8007) contained in (original) objects.package:

  • 0x8000 - 1
  • 0x8001 - 2
  • 0x8002 - 25
  • 0x8003 - 75
  • 0x8004 - 4
  • 0x8005 - 285
  • 0x8006 - 1,357
  • 0x8007 - 15,507
  • 0x8008 & 0x8009 introduced later
