Tes4Mod:Mod File Format/INFO

The UESPWiki – Your source for The Elder Scrolls since 1995

An INFO record defines a dialog response. There is a sequence of TRDT, NAM1 and NAM2 subrecords for each response associated with the INFO record. There is a CTDA subrecord for each dialog condition, a TCLT subrecord for each choice, and a NAME subrecord for each add topic.

The INFO records are contained in a Topic group. The INFO records must occur in the order defined by the PNAM subrecords. The first INFO record in the group has a PNAM subrecord containing a form ID of 0. The second INFO record has a PNAM subrecord containing the form ID of the first INFO record. And so forth.

	ubyte[3]	Unknown
	float	Comparison value
	long	Function index. See Functions for a list of function indices.
	formid/long	First parameter. This can be a number or a Form ID depending on the function.
	formid/long	Second parameter. This can be a number of a Form ID depending on the function
	formid/long?	Third parameter?
TCLT	formid	Choice
NAME	formid	Add topic
SCHR	struct	Result script data. See SCHR for more information.
SCDA	struct	Compiled result script. See SCDA for more information.
SCTX	string	Result script source.
SCRO	formid	Global variable reference. There is an SCRO subrecord for each global reference.
CTDT	20 bytes	Seems to be the same structure as the CTDA except missing the last 4 bytes. This may be an 'older' version of the CTDA subrecord which needed to be expanded at some point. New/modified INFOs seem to use CTDA subrecords even if the original record used CTDTs.
