API:SetHotbarData

UI Lua API · Hotbar functions
Version: WAR 1.4.8

Puts an action into a hotbar slot, or clears the slot.

SetHotbarData(slot, actionType, actionId)

Arguments

slot: number – Hotbar slot, 1 to 132 (GameData.HOTBAR_TOTAL_SLOT_COUNT). A value of 0 or less places the action in the first empty slot; the stock UI uses -1.
actionType: number – Type of the action, a GameData.PlayerActions value. 0 together with actionId 0 clears the slot.
actionId: number – Id of the action (ability id, item id, macro slot, …).

Nothing.

Before writing, the client checks the slot and the ability against the player's hotbar state and does nothing if the check fails.
If the slot already holds the same action, nothing changes.
When the slot changes, the client sends the change to the server for slots that the server stores, and notifies the UI for every hotbar slot that shows this entry.
If no slot is empty when slot is 0 or less, nothing is stored.
For a slot above 132 the error below is logged (not raised as a Lua error) and nothing changes.

Error in function call 'SetHotbarData': slot must be less than GameData.HOTBAR_TOTAL_SLOT_COUNT. (logged)
The generic Invalid Parameters message when an argument is not a number.
