Asks the server to add an item from a backpack to a crafting session (talisman making, apothecary or cultivation).<br />
<br />
<pre><br />
AddCraftingItem(tradeSkill, craftingSlot, backpackSlot, backpackType)<br />
</pre><br />
<br />
== Arguments ==<br />
;tradeSkill : <code>number</code> – A <code>GameData.TradeSkills</code> value: <code>CULTIVATION</code> (3), <code>APOTHECARY</code> (4) or <code>TALISMAN</code> (5).<br />
;craftingSlot : <code>number</code> – For cultivation, the plot number (starting at 1). For apothecary and talisman making the client does not send it.<br />
;backpackSlot : <code>number</code> – Slot of the item inside the backpack, starting at 1.<br />
;backpackType : <code>number</code> – Which backpack the item is in, as an <code>EA_Window_Backpack.TYPE_*</code> value (2 = inventory, 3 = currency, 4 = crafting).<br />
<br />
== Returns ==<br />
Nothing.<br />
<br />
== Details ==<br />
* <code>backpackSlot</code> and <code>backpackType</code> are converted to an absolute inventory slot.<br />
* With trade skill 3 the request is a cultivation request for the given plot. With 4 or 5 it is a crafting "add ingredient" request for that skill. With any other value the client sends the same message type without a crafting command.<br />
* If a certain player state flag is set, the client adds a fixed message to the <code>Chat</code> text log instead of sending the request.<br />
* The client does not check that the item fits the crafting slot. The stock crafting windows check the item type themselves and track which crafting slot holds which item.<br />
* The function needs at least four arguments and only reads the last four.<br />
<br />
== Errors ==<br />
None besides the generic ''Invalid Parameters'' message when an argument is not a number.<br />
<br />
== Example ==<br />
From <code>default/ea_craftingwindow/source/apothecarywindow.lua</code>:<br />
<pre><br />
if( slotNum == ApothecaryWindow.SLOT_CONTAINER)<br />
then<br />
AddCraftingContainer( GameData.TradeSkills.APOTHECARY, backpackSlot, backpackType )<br />
else<br />
AddCraftingItem( GameData.TradeSkills.APOTHECARY, slotNum, backpackSlot, backpackType )<br />
end<br />
</pre><br />
<br />
Planting in a cultivation plot, from <code>default/ea_cultivationwindow/source/cultivationwindow.lua</code>:<br />
<pre><br />
