This function is PROTECTED, and can only be called from Blizzard code. It has been protected since patch 2.0.1. For alternatives, try Secure Templates or the new Conditional slash commands.

Perform the specified action.

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

Parameters Edit

Arguments Edit

slot 

Numeric - The action slot to use.

checkCursor 

Flag (optional) - 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 (optional) - 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 Edit

none

Example Edit

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

Result Edit

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