The way scripts are stored, they each contain a command number, a variable number, and any number of arguments. When a variable number is not given, a "0" is used. So when the key below says that the variable is "optional", that means that it has been found both with and without a variable being passed in. In some cases, the syntax of the arguments depends on whether a variable was passed in. In this case, the variable/arguments header is repeated for each form of the command.

Myst
Mohawk Overview
CLRC EXIT HINT INIT
MJMP MSND PICT RLST
VIEW WDIB HELP RSFL
Scripts Variables

This page contains, or will contain, a list of all known commands in Myst, as used in record types 5, 6, 7, 8, 10, 11, and 12. The script format always starts with an unsigned short representing the command count, and then per command has this structure:

unsigned short opcode
unsigned short var
unsigned short num_values
unsigned short values[num_values]

The way scripts are stored, they each contain a command number, a variable number, and any number of arguments. When a variable number is not given, a "0" is used. So when the key below says that the variable is "optional", that means that it has been found both with and without a variable being passed in. In some cases, the syntax of the arguments depends on whether a variable was passed in. In this case, the variable/arguments header is repeated for each form of the command.

Commands 0-99

These are suspected to be general-purpose commands.

Command 0

  • Variable: Optional
  • Arguments: None

Seems to toggle a variable between 0 and 1. For example, see the marker switches on MYST island.

Command 1

  • Variable: Optional
  • Arguments: u0

Could mean "set variable to u0". u0 takes on any number between 0 and 7 (maybe a bit field?)

Command 2: alternative destination

  • Variable: Yes
  • Arguments: dest

This command goes to dest instead of the regular destination if var is a certain (unknown) value. (Only used for SELEN 1240 and CHANNEL 3359)

Command 3: change cursor

  • Variable: Yes
  • Arguments: clrc_id
  • clrc_id is always 800, 801, or 802. (Only 5 different cases). These are the "animated" cursors of dropping the white, red, and blue pages, respectively.

This command seems to change cursor to clrc_id if var is a certain (unknown) value.

Command 4

  • Variable: Optional
  • Arguments: None

Command 6

  • Variable: Optional
  • Arguments: None

Command 7

  • Variable: Optional
  • Arguments: None

Command 8

  • Variable: Optional
  • Arguments: None

Command 9

  • Variable: No
  • Arguments: [u0]
  • u0 is always either FFFF or omitted.

Command 12

  • Variable: Optional
  • Arguments: u0

Related to command 13.

  • u0 appears to be a nearby card.

This may have similar function to command 2.

Command 13

  • Variable: Optional
  • Arguments: u0

Related to command 12.

  • u0 appears to be a nearby card.

This may have similar function to command 2.

Command 14

  • Variable: Optional
  • Arguments: u0
  • u0 is always 0, 1, or 2.

Command 15

  • Variable: Yes
  • Arguments: [u0]
  • u0 is always 0 or omitted.

Command 16

  • Variable: No
  • Arguments: u0 u1
  • u0 appears to be a nearby card.
  • u1 is always 0.

Command 17

  • Variable: No
  • Arguments: u0 u1
  • u0 appears to be a nearby card.
  • u1 is always 4, 5, or 6.

Command 18

  • Variable: No
  • Arguments: u0
  • u0 is always 4, 5, or 6.

Command 19: enable hotspots

  • Variable: No
  • Arguments: count u0[count]

This seems to enable a list of hotspots. All of the u0 numbers are small (0-13, 21).

Command 20: disable hotspots

  • Variable: No
  • Arguments: count u0[count]

This seems to disable a list of hotspots. All of the u0 numbers are small (0-13, 21). These, unlike command 19, can also be -1, which seems to disable the invoking hotspot.

Command 21

  • Variable: No
  • Arguments: u0 u1 u2 u3 u4 u5

There are this command is used 6 times.

  • u0 is always 0, 74, 76, 117, or 198.
  • u1 is always 0, 48, 213, or 226.
  • u2 is always 327, 406, 429, 459, or 544.
  • u3 is always 257, 332, or 333.
  • u4 is always 0, 1, 5, 6, or 11.
  • u5 is always 5 or 25.

Command 22

  • Variable: No
  • Arguments: None

Command 23

  • Variable: No
  • Arguments: count u0[count]
  • The u0 numbers are all 0, 4, or 5.

Command 24

  • Variable: No
  • Arguments: u0
  • u0 appears to be a sound ID.

Command 26

  • Variable: No
  • Arguments: None

Command 27

  • Variable: No
  • Arguments: u0
  • u0 appears to be a sound ID.

  • Variable: No
  • Arguments: pict_id <l t r b> u0 u1
  • pict_id appears to be a picture ID.
  • <l t r b> often corresponds with the intended location of one of the sub-images in the VIEW resources.
  • u0 appears to be a variable number (it is sometimes 0).
  • u1 may also be a variable number (it is sometimes 0, 1, or -1).

This command seems to copy picture pict_id over the hotspot, using <l t r b> as the source rect. Additional data is unknown.

Command 30

  • Variable: No
  • Arguments: <msnd_id flags> [...]
  • msnd_id looks like background sound ID to play.
