Asks the server to buy a career advance (ability, mastery point, renown or tome reward) from the trainer the player is talking to.<br />
<br />
<pre><br />
BuyCareerPackage(tier, category, packageId)<br />
</pre><br />
<br />
== Arguments ==<br />
;tier : <code>number</code> – Tier of the advance (the <code>tier</code> field of the advance data).<br />
;category : <code>number</code> – Category of the advance, a <code>GameData.CareerCategory</code> value (the <code>category</code> field of the advance data).<br />
;packageId : <code>number</code> – ID of the advance (the <code>packageId</code> field of the advance data).<br />
<br />
== Returns ==<br />
Nothing.<br />
<br />
== Details ==<br />
* Sends a purchase request with the three values and a value identifying the player's current NPC interaction. <code>tier</code> and <code>category</code> are cut to 8 bits, <code>packageId</code> to 16 bits.<br />
* The client does not check that the player can afford the advance or meets its requirements. The server decides; the stock training windows assume the purchase worked.<br />
* Nothing is sent if the connection is not ready.<br />
* The function needs at least three arguments and only reads the last three.<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_interactionwindow/source/interactioncoretraining.lua</code>:<br />
<pre><br />
local packageID = EA_Window_InteractionCoreTraining.advanceData[dataIndex].packageId<br />
local tier = EA_Window_InteractionCoreTraining.advanceData[dataIndex].tier<br />
local category = EA_Window_InteractionCoreTraining.advanceData[dataIndex].category<br />
BuyCareerPackage( tier, category, packageID )<br />
</pre><br />
