This page covers implementing the GCS data model for characters, various item types (traits, skills, equipment, etc.) and other related utility functions in GGA. The functionality of GGA differs from that of GCS, so some adjustment will be necessary, but the data should be able to be converted without any data loss or difficulty.

Actors for now consist only of Characters. This corresponds to the Entity structure defined in GCS' model/gurps/entity.go

The below table shows the GCS data model fields as well as suggested corresponding field names and types for GGA.

GCS Key	GCS JSON Key	GCS Type	GGA Key	GGA Type	Description
Version	version	int	version	NumberField	GCS file version field. Used for compatibility checking
ID	id	tid.TID	tid	StringField / TidField	ID used within GCS. Can be used for validation
TotalPoints	total_points	fxp.Int	totalPoints	NumberField	Character point total. May be deprecated in GCS? (to check)
PointsRecord	points_record	[]*PointsRecord	pointsRecord	ArrayField	Record of point changes with timestamps and notes.
Profile	profile	Profile	profile	SchemaField	Record of description info (height, weight, SM, TL, etc.)
SheetSettings	settings	*SheetSettings	settings	SchemaField	Various display settings as well as hit location table and attributes setup. Ideal structure may vary from GCS', see CharacterSettingsSchema below.
Attributes	attributes	*Attributes	attributes	AttributesField	Set of current attribute values. See AttributesField below.
Traits	traits	[]*Trait	traits	accessor () => subset of actor.items	List of character advantages/disadvantages (hierarchical)
Skills	skills	[]*Skill	skills	accessor () => subset of actor.items	List of character skills/techniques (hierarchical)
Spells	spells	[]*Spell	spells	accessor () => subset of actor.items	List of character spells (hierarchical)
CarriedEquipment	equipment	[]*Equipment	carriedEquipment	accessor () => subset of actor.items	List of carried character equipment (hierarchical)
OtherEquipment	other_equipment	[]*Equipment	otherEquipment	accessor () => subset of actor.items	List of non-carried character equipment (hierarchical)
Notes	notes	[]*Note	notes	ArrayField (needs discussion)	List of character notes (hierarchical)
CreatedOn	created_date	jio.Time	createdDate	StringField / TimeField (needs discussion)	Date on which character was created
ModifiedOn	modified_date	jio.Time	modifiedDate	StringField / TimeField (needs discussion)	Date on which character was last modified
ThirdParty	third_party	map[string]any	Special1	Special1	Used by GCS for non-GCS data

The GCS Entity struct also makes use of properties which are not written to the file but rather exist only in the initialised Entity. These, alongside their proposed GGA equivalents, are as follows:

GCS Key	GCS Type	GGA Key	GGA Type	Description
LiftingStrengthBonus	fxp.Int	#cache.liftingStrengthBonus	number	Cached lifting strength bonus
StrikingStrengthBonus	fxp.Int	#cache.strikingStrengthBonus	number	Cached striking strength bonus
ThrowingStrengthBonus	fxp.Int	#cache.throwingStrengthBonus	number	Cached throwing strength bonus
DodgeBonus	fxp.Int	#cache.dodgeBonus	number	Cached dodge bonus
ParryBonus	fxp.Int	#cache.parryBonus	number	Cached all-weapon parry bonus
BlockBonus	fxp.Int	#cache.blockBonus	number	Cached all-weapon block bonus
ParryBonusTooltip	string	#cache.parryBonusTooltip	string	Cached all-weapon parry bonus tooltip text
BlockBonusTooltip	string	#cache.blockBonusTooltip	string	Cached all-weapon block bonus tooltip text
