New page

{{LuaApi|group=Hotbar}}
Asks the server to place a morale ability in a morale bar slot, or to clear the slot.

<pre>
SetMoraleBarData(moraleLevel, abilityId)
</pre>

== Arguments ==
;moraleLevel : <code>number</code> – Morale slot, 1 to <code>GameData.NUM_MORALE_LEVELS</code> (4). It is converted to an 8-bit integer.
;abilityId : <code>number</code> – Id of the morale ability, or 0 to clear the slot. It is converted to a 16-bit integer.

== Returns ==
Nothing.

== Details ==
* The client only sends the request; it does not change its own copy of the morale bar here.
* Nothing is sent if the connection is not ready.
* For a slot outside 1 to 4 the error below is logged (not raised as a Lua error) and nothing is sent.
* The function needs at least two arguments and only reads the last two.

== Errors ==
* <code>Error in function call 'SetMoraleBarData': moraleSlotId must be 1 to GameData.NUM_MORALE_LEVELS.</code> (logged)
* The generic ''Invalid Parameters'' message when an argument is not a number.

== Example ==
From <code>ea_moralewindow/source/moralewindow.lua</code>:
<pre>
SetMoraleBarData (self.m_MoraleLevel, Cursor.Data.ObjectId)
</pre>

Clearing a slot, from the same file:
<pre>
SetMoraleBarData (self.m_MoraleLevel, 0)
</pre>
