This page explains how the game stores and parses weapon data. This is an advanced guide for mod developers.

==Raw data==
 
−
Weapon sprites are in <tt>TileSheets\Weapons.xnb</tt>, and weapon data (parsed by the <tt>MeleeWeapon</tt> constructor) is in <tt>Data\Weapons.xnb</tt>. The files can be [[Modding:Editing XNB files#unpacking|unpacked for editing]]. Here's the raw data as of {{version|1.4}} for reference:

Weapons have a hardcoded category of -98 (<tt>Object.weaponCategory</tt>).

===Slingshot===
 
−
The [[slingshot]] has initial ID 32 in the weapon data, which increases by one for each upgrade level (up to 34 in the weapon data, though only 32 and 33 are obtainable without mods). All [[#Melee weapons|weapon fields]] must be specified in the weapon data to avoid errors, but only these are actually used for slingshots:

Slingshot damage is [[Slingshot#Ammunition|calculated dynamically]] regardless of the weapon data.

==Mine container drops==
 
−
When the player breaks a container in [[The Mines|the mines]], there's a chance it will drop a weapon. Here's how the weapon to drop is chosen<ref>See <tt>Utility.getUncommonItemForThisMineLevel</tt> in the game code.</ref>:
 
−
 
 
−
<ol>
 
−
<li>Match weapons whose minimum mine level ([[#Format|field 10]]) is less than the current mine level.</li>
 
−
<li>From that list, match weapons with a probability check based on the gap between the base mine level ([[#Format|field 9]]) and current mine level. The probability is a bell curve centered on the base mine level:

−
The difference applies in both directions; for example, two weapons whose base levels are 5 below and 5 above the current level both have a 92% chance. (The probability is calculated with a [[wikipedia:Gaussian function|Gaussian function]] <code>e<sup>-(current mine level - base mine level)<sup>2</sup> / (2 * 12<sup>2</sup>)</sup></code>.)</li>
 
−
<li>Find the weapon with the smallest gap between the current and base mine levels, and add it to the list. (If the item was also selected in step 2, it has two chances to drop.)</li>
 
−
<li>From the remaining list of weapons, randomly choose one to drop.</li>
