AndreyNazarov: /* Command 111 */ makes hotspot not drawable

{{Myst}}
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:

{| class="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.

==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 18==
*'''Variable:''' No
*'''Arguments:''' ''u0''

*''u0'' is always 4, 5, or 6.

==Command 19: enable hotspots==
*'''Variable:''' No
*'''Arguments:''' ''count'' ''u0''[''count'']

==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|command 19]], can also be -1, which seems to disable the invoking hotspot.

Myst scripts

2008-09-19T13:15:22Z

AndreyNazarov: /* Command 103 */ makes hotspot drawable in it's second form

{{Myst}}
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:

{| class="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.

==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

*''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|command 19]], can also be -1, which seems to disable the invoking hotspot.

==Command 21==

Myst RLST resources

2008-09-19T12:50:16Z

AndreyNazarov: Updated info on hotspot flags, minor fixes.

{{Myst}}

These contain Myst's hotspot descriptions.

The data is a list of records, each record describing one of the hotspots:
{| class="structure"
|short||record_count
|-
|variable||records
|}

The record length is variable, depending on the hotspot type. The record structure is:
{| class="structure"
|unsigned short||type
|-
|unsigned short||flags
|-
|short||left
|-
|short||top
|-
|short||right
|-
|short||bottom
|-
|unsigned short||destination
|-
|variable||additional data
|}
*''type'' seems to specify the hotspot action in a wide sense. Every value between 0 and 14 except for 9 has been observed. See below for the meaning.
*''flags'' seems to be a bit field. Observed values are 0, 1, 2, 3, 4, 5, 8 and 10 (4 variable bits). The value seems related to when the hotspot actions should be executed. For example, regular clickable hotspots usually have bit 1 set while hotspots that run background movies (e.g. the Channelwood windmill) have ''flags'' = 0. Bit 0 seems to indicate whether hotspot subimages are to be drawn (at least for type 8 hotspots). Hotspots with bit 2 set usually don't have any other bits set (except bit 0, encountered only twice). Bit 3 is suspected to flag Zip Mode hotspots.
*The following 4 fields define the hotspot rectangle. Note that "weird" rectangles are found, like (-32000, -32000, 32000, 32000).
*''destination'' contains a destination card ID for hotspots that change card, or zero.
*Additional data follows when ''type'' > 4 (complex hotspots), clearly representing lists of actions to perform. We have yet to figure out how to calculate the length of those complex records.

==Hotspot types==
Types from 0 to 4 are associated with "simple" hotspots that usually just change card. In these cases, ''type'' indicates the movement direction: forward, left, right, down and up respectively. There is no additional data in the hotspot record for these simple cases.

Type 5 hotspots have a script attached to them. See the [[Myst_scripts|page about scripts]] for the structure of scripts.

Type 6 hotspots play a video when activated. The record starts with a full type 5 record. Then comes a zero-terminated string (C string) which defines the path to the video file without extension. Note that after the string is read, input stream position should be padded to the next 2-byte boundary. Finally come 7 shorts whose purpose is still unknown.

Type 7 record serves as some kind of switch statement, executing one of several action lists (or cases) indexed by the value of a variable:

(var_index) {num_cases} [record_type <record_data>]

Each case itself begins with a record type, followed by additional record contents (without common prefix). Only type 5 and 6 records used in a switch statement have been observed.

Type 8 record is like type 7, but additionally it specifies a list of subimages to draw over main WDIB. The particular subimage is chosen depending on the value of variable. This record includes the type 7 record at start.

<type_7_record> (var_index) {num_subs} [wdib_id <rectangle>]

Here, each subimage record defines a source WDIB ID and a source rectangle inside this WDIB. Rectangle is defined in the usual (''left'', ''top'', ''right'', ''bottom'') format, with one exception: empty rectangle is defined as the single short -1. This is probably the case when source rectangle equals destination rectangle. Also, ''wdib_id'' itself can be -1, this probably means original WDIB for this card should be used as source WDIB.

The remaining types are being investigated.

==Case studies==
Note: these are simply the data in little-endian shorts and line-broken where patterns are found. <l t b r> is the hotspot rect. count [entry]... are guesses at when there are lists of entries. The number in parentheses before the data is the card number (not the resource number).

The following hotspots replace part of the image (in this case <417 260 544 333>) with part of another image (in this case 3004 <0 0 127 73>) based on a variable (103 2 plays in here somewhere):

==== Intro Case Study ====
(INTRO 1) 1
0 2 <-32000 -32000 32000 32000> 5

INTRO 1 is supposed to be the card which shows the opening movies and then switches to card 2.

(INTRO 2) 1
5 2 <245 202 304 253> 4 2 [37 0 0] [34 0 2 {3 11}]

INTRO 2 is the first interactive part of the game, the part where you can pick up the Myst book. The rect correctly corresponds to where the book is on screen. But, look at the "destination" -- 4. There is no VIEW/RLST 4! However, there is a WDIB 4 and it is the open book with the water. Where this ''should'' go is to card 3 and show the Myst book cover before showing image 4 and then playing the video. And, there is a 3 in this chunk, but I'm not sure if that's the purpose. I have no idea what commands 37/34 could be. There is a WDIB 11, but it's of D'ni, so I doubt it's that. ;)

(INTRO 3) 2
0 2 <-32000 -32000 32000 32000> 5
6 0 <312 70 441 159> 0 0 "\qtw\intro\intro2" 0x2848 0x2756 0 1 0 0 0

Note that this one has a string for the video (null-terminated). This obviously calls that video which is the Myst fly-by for the linking book. And, that rect perfectly matches where the video should be displayed on screen. However, this also clearly breaks the format specified above for "type 2 hotspots".

WDIB 3 is the cover of the Myst linking book. But, this doesn't match up with the video mentioned here which should be for WDIB 4 (or 10, they are identical)(the open linking book with the water image) and eventually ending at WDIB 12 (the open linking book with the dock image). The 5 after the very large numbers is the target card for the open linking book which seems correct. 0x2848 is 10,312 and 0x2756 is 10,070. The rate of the audio is 11,025. Not sure if this has any correlation.

Myst MJMP resources

2008-09-13T11:59:02Z

AndreyNazarov: Added description of MJMP resources

MJMP resources (Msnd JuMPs) define aliases for identical sounds in Myst Masterpiece Edition, which were previously packaged as separate MSND resources, wasting disk space. Each resource of type MJMP contains a single little-endian short referencing real MSND ID.

AndreyNazarov: /* Command 40: travel between ages */ oops, clarification

{{Myst}}
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. Specifics on the format itself can be found at [[Myst RLST resources]]. 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.

AndreyNazarov: /* Command 3 */ seems to change cursor

{{Myst}}
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. Specifics on the format itself can be found at [[Myst RLST resources]]. 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.

AndreyNazarov: Values for some commands strongly appear to be sound IDs. Command 118 actually appears 3 times, not 2.

{{Myst}}
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. Specifics on the format itself can be found at [[Myst RLST resources]]. 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.
