Unit Info related events

This event is fired whenever the player's focus target (/focus) is changed, including when the focus target is lost or cleared.

This event is fired whenever the player's target is changed, including when the target is lost.

The arg1--arg9 values are undefined; they will be whatever they were in the previous event, i.e. if you click a unit portrait to change target, arg1 will be "LeftButton" - if you click a macro button, it will be the macro script, etc.

There used to be an old notice here about UnitName() et al not returning correct info immediately after a target change, but as even FrameXML itself depends on it doing so, I assume that's outdated and/or inaccurate information.

UnitName("target") returns the correct name, but UnitName("targettarget") does not.

New in 1.11. Fired when a raid target icon is changed or removed. Also fired when player join or leave a party or raid. arg1 is who gets updated.

Note: Does not get triggered if a mob wearing a raid target icon dies (the icon is removed from that mob, however.)

Question/Correction: I can not pick up arg1 at all from this event. Change in 1.12? Please clarify if possible. Question/Correction: You are correct. The only arg is 1, which is the event name itself. --Robinson 02:34, 15 January 2007 (CDT)

Fired when a units attack is affected (such as the weapon being swung). First argument returned appears to be which unit this even applies to (for example, 'player').

Fired when a unit's attack power changes.

Fired when your attack speed is being listed or affected

Fired when a buff, debuff, status, or item bonus was gained by or faded from a player, pet, NPC, or mob.

1-28-06: This event IS NOT fired when changing targets any longer.

Seems like the same as UNIT_AURA above (including arguments) but only for short buffs. As a Paladin, it was triggered each time I gained a 30 second buff (Paladin Seals), lost/canceled it, or switched targets from another player to myself. Needs more testing with other classes etc.

Same as UNIT_MANA, except for certain classes. Hunter used to use focus, but now they use mana. But it is still used when a pets energy changes.

Fired when the Pet Happiness changes. Used in PetFrame.lua to decide when to update the happiness display.

Fired whenever a units health is affected.

This event may be sent more than once to represent the same change if the affected entity can be accessed through multiple UnitIDs. For example, two UNIT_HEALTH events will be sent for raid party members who are also in your party group.

UNIT_HEALTH events are sent for raid and party members regardless of their distance from the character of the host. This makes UNIT_HEALTH extremely valuable to monitor party and raid members.

arg1 

the UnitID of the unit whose health is affected

Seen unit names:

• player, pet, target, mouseover, party1..4, partypet1..4, raid1..40

Fired when the player equips or unequips an item. This can also be called if your target, mouseover or party member changes equipment (untested for hostile targets).

This event is also raised when a new item is placed in the player's containers, taking up a new slot. If the new item(s) are placed onto an existing stack or when two stacks already in the containers are merged, the event is not raised. When an item is moved inside the container or to the bank, the event is not raised. The event is raised when an existing stack is split inside the player's containers.

If multiple slots are equipped/unequipped at once it only fires once now. However it still fires many times (potentially hundreds) while zoning or logging in.
