COMBAT LOG EVENT

Fires for Combat Log events such as a player casting a spell or an NPC taking damage.

• COMBAT_LOG_EVENT only reflects the filtered events in the combat log window
• COMBAT_LOG_EVENT_UNFILTERED (CLEU) is unfiltered, making it preferred for use by addons.

Both events have identical parameters. The event payload is returned from, or from if selected using.

• subevent: - The combat log event, for example.
• hideCaster: - Returns true if the source unit is hidden (an empty string).
• guid: - Globally unique identifier for units (NPCs, players, pets, etc), for example.
• name: - Name of the unit.
• flags: - Contains the flag bits for a unit's type, controller, reaction and affiliation. For example : Unit is the current target, is an NPC, the controller is an NPC, reaction is hostile and affiliation is outsider.
• raidFlags: - Contains the raid flag bits for a unit's raid target icon. For example : Unit is marked with.

Combat log messages may be written to the file for external parsing purposes. This feature can be enabled with or toggled with the /combatlog slash command. Combat logging was added on patch 1.7.0

This log line is added when combat logging starts.

There can be up to 39 parameters, in order:

• 9 base params (subevent, source and dest unit)
• 0 to 3 prefix params (spell/environmental)
• 17 advanced params
• 0 to 10 suffix params

Advanced parameters require CVar advancedCombatLogging Default: Whether we want advanced combat log data sent from the server (added in 5.4.2) to be enabled for meaningful values.
