A dipscript, or "diplomat script", is what controls the behavior of visiting diplomats when they meet with your nobles. Dipscripts were originally used to trigger special events at specific points in the lifetime of one's fortress (such as undead invasions), but much of this was stripped out by the time the first version of Dwarf Fortress was actually released.
Only 5 different dipscripts are ever executed during gameplay, and they are defined in records 13-17 of the game's "index" file: ELVES_FIRSTCONTACT, HUMAN_STANDARD, DWARF_LIAISON, HUMAN_TRADE, and ELVES_STANDARD. The dipscript files themselves are compressed - with the proper tools, editing them is fairly straightforward.
Script Tokens
| Token
|
Meaning
|
| INITIAL_LOAD
|
Presumably indicates that the dipscript should be loaded on game startup instead of on-demand. All of the default dipscripts specify this, as the game does not appear to contain logic for dynamic loading.
|
| DIPSCRIPT:name
|
Specifies the script's name. Must be one of the names defined above if you want the game to ever execute it.
|
| VAR:type:name
|
Declares a variable. Type can either be UNIT or LONG.
|
| SETVAR:dest_class:dest_name:src_class:src_name
|
Sets one variable to another. See below for more information.
|
| IF:class1:name1:comparison:class2:name2
|
Compares the two specified variables and performs the following script steps if the condition is true.
|
| ELSE
|
Performs the following script steps if the above IF condition was false.
|
| ENDIF
|
Ends the above IF statement
|
| TEXTVIEWER:filename:varname
|
Opens a text viewer using the specified filename (located within data/dipscripts/text). Second parameter is optional - if specified, indicates a LONG script variable which will be set based on the hyperlink selected.
|
| CONSTRUCTTOPICLIST
|
Builds a list of appropriate discussion topics (discuss current agreement, request peace treaty, propose tree quota, establish export agreement, establish import agreement, make liaison request, or make small talk), based on the type of civilization the diplomat came from.
|
| TOPICDISCUSSION
|
Discuss all topics selected via CONSTRUCTTOPICLIST.
|
| DISCUSS:length
|
Inserts a delay into the meeting. Valid lengths are SHORT (500-1000 steps, about a half a day) and LONG (2-4 days).
|
| HISTORY_DIPEV:type
|
Records a historical event once the diplomat leaves your fortress. The only valid event type is FIRSTCONTACT, used by the Elves to control whether or not they will send their diplomat to propose logging quotas.
|
| ACTION:type:subtype
|
Performs a simple action. Only valid action is DREAM:UNDEAD_ARMY, which causes one of your dwarves to have "a terrifying nightmare about an army of the dead".
|
| DIPEVENT:parm1:parm2:parm3:parm4:parm5
|
Has no effect. Most likely, pre-release versions used this to perform special actions.
|
| INVASION:parm
|
Has no effect. Most likely, pre-release versions used this to trigger invasions of specific types.
|
Variables
Dipscripts (and their text screens) can make use of any number of special variables. Each variable has a class, name, and type.
