Editing WoW:API UseAction

{{wowapi}}
{{protectedapi|2.0.1|For alternatives, try [[API SecureTemplates|SecureTemplates]] or the new [[Conditional slash commands]].}}

Perform the specified action. 

 UseAction(slot[, checkCursor[, onSelf]])

== Parameters ==
=== Arguments ===
:;slot
:: Numeric - The action [[ActionSlot|slot]] to use.
:;checkCursor
:: Flag <small>''(optional)''</small> - Can be 0, 1, or nil. Appears to indicate whether the action button was clicked (1) or used via hotkey (0); probably involved in placing skills/items in the action bar after they've been picked up. I can confirm this. If you pass 0 for checkCursor, it will use the action regardless of whether another item/skill is on the cursor. If you pass 1 for checkCursor, it will replace the spell/action on the slot with the new one.
:;onSelf
:: Flag <small>''(optional)''</small> - Can be 0, 1, or nil. If present and 1, then the action is performed on the player, not the target. If "true" is passed instead of 1, Blizzard produces a Lua error.

=== Returns ===

:''none''

== Example ==

 action = 18 -- Change this to the slot number you want to activate
 UseAction(action, 0, 1)

=== Result ===

 -- Causes action bar slot #18 to be cast on the player, regardless
 -- of whether the cursor is currently "holding" an item or ability.

== Details ==

See the [[actionSlot]] API Type for more information on slot numbers and example code for listing available slots.
