Enum reference

arcdps’ combat-event enums are not defined in the API README — like cbtevent itself, they live in the separate EVTC combat-log format documentation (https://www.deltaconnected.com/arcdps/evtc/README.txt), which this page is sourced from. Field names below match the C source exactly; the arcdps API README calls the on-ev discriminant field is_statechange, and the EVTC docs name the enum backing it cbtstatechange — the two refer to the same thing.

Every enum here is 0-indexed and sequential (each enumerator’s value is the previous value + 1) unless otherwise noted — n_customskill is the one exception, explicitly starting at 23275.

cbtstatechange (the is_statechange field)

This is the event-type discriminant on cbtevent — its value determines how every other field on the struct (besides time) is interpreted. The “Meaning” column below is the enum’s own inline comment; the full per-field payload mapping for every event type, including each type’s evtc/realtime availability, is on the statechange payloads page. Entries suffixed _DEFUNC are explicitly marked retired in the source and should not be relied on for current arcdps builds.

n_customskill (synthetic skill ids)

Synthetic skillid values arcdps emits for events that aren’t a real game skill (e.g. dodges, weapon swaps). Unlike the enums above, this one does not start at 0 — CSK_DODGE is explicitly assigned 23275, and every subsequent enumerator increments sequentially from there.

Value	Name	Meaning
23275	CSK_DODGE	undocumented — no inline comment given
23276	CSK_DEFIANCEDAMAGE	undocumented — no inline comment given

23308	CSK_PICKUP	item id given in the paired CBTS_ANIMATIONSTART event
23309	CSK_GENERICFALLDOWN	undocumented — no inline comment given

gwlanguage (text language)

Backs the CBTS_LANGUAGE statechange’s src_agent payload. Note the gap: there is no value 1.

Value	Name	Language
0	GWL_ENG	English
2	GWL_FRE	French
3	GWL_GEM	German
4	GWL_SPA	Spanish
5	GWL_CN	Chinese

The Unofficial Extras Language enum uses identical values.

n_contentlocal (content types)

Backs the overstack_value of CBTS_IDTOGUID events — the type of content whose id-to-GUID association is being reported. Sequential from 0.

Value	Name	Notes (from the source’s inline comments)
0	CONTENTLOCAL_EFFECT	src_instid: content type; (float*)&buff_dmg is the default duration, if available (when the effect event has no duration or agent set)
1	CONTENTLOCAL_MARKER	src_instid: is in commander-tag defs
2	CONTENTLOCAL_SKILL	no extra data — see CBTS_SKILLINFO/CBTS_BUFFINFO events
3	CONTENTLOCAL_SPECIES_NOT_GADGET	no extra data
4	CONTENTLOCAL_EMOTE	no extra data
5	CONTENTLOCAL_TRANSFORMATION	no extra data

The source also defines two enums marked “(debug only, subject to change)” — n_animationstart and n_animationstop — which are not reproduced here because the source itself flags them as unstable.

Profession ids (community)

The EVTC docs don’t enumerate profession ids; the values below are community knowledge (used identically by the Rust bindings and matching the game’s code values from the official GW2 web API’s /v2/professions endpoint). They back ag.prof for players, evtc_agent.prof, and the value field of CBTS_ENTERCOMBAT/CBTS_EXITCOMBAT.

Value	Profession
0	unknown
1	Guardian
2	Warrior
3	Engineer
4	Ranger
5	Thief
6	Elementalist
7	Mesmer
8	Necromancer
9	Revenant

This ordering is corroborated by the arcdps binary itself: its icon strings run 001–009 and its profession list appears in exactly this order (“guardian, warrior, engineer, ranger, thief, elementalist, mesmer, necromancer, revenant”) in the settings UI strings. Elite specialization ids (ag.elite / evtc_agent.is_elite) are the game’s specialization ids from /v2/specializations — a larger, game-managed id space not enumerated here (0xFFFFFFFF marks a non-player agent; see the EVTC agent classification rules).
