Modding:Coding An Item

Now, you have made a mesh for a certain race. We are going to add it to the game.

First, we add the mesh we created to the We now open our meshes.lsx which we created in.

Note that this is a circlet, so it doesn't need to hide any part of the body. But if it had that code, it would go here. Example:

<node id="VertexColorMaskSlots">
<attribute id="Object" type="FixedString" value="feet" />
</node>

And this code would stop the body's feet from loading in and clipping, ideal for boot items. See here for a full list of Vertex Mask Slots for the body.

Now, let's see how this links up to the localisation. You can generate a handle by ticking the Handle box next to 'GENERATE' on the Multitool. It is much like an UUID but it starts with an H.

<?xml version="1.0" encoding="utf-8"?><contentList>
<content contentuid="HANDLE1" version="1">Circlet</content> 
<content contentuid="HANDLE2" version="1">My circlet is cool.</content>
</contentList>

Meanwhile in your Armor.txt, they link up like this: You can look at the games own armor.txt for ideas of what to put here. You can delete a lot of this, all you really need is the entry, the type, what slot it uses and the RootTemplate.

Armor.txt
new entry "MY_COOL_NEW_CIRCLET"
type "Armor"
data "ValueOverride" "4000" (It's a very cool circlet and we want it to cost a lot!)
data "Weight" "0.01"
using "_Head_Magic_Circlet" (This tells it what slot to equip in. Ideally this should match up with the ParentTemplate you set up.)
data "RootTemplate" "0000000000000000000000000002" Matches up to the rootemplate Mapkey.
data "Rarity" "Rare" This effects what colour it is in your inventory, rarer things get a different colour outline. Note that if you set things as common they may spawn in generic containers, which is not optimal for clean uninstalling.
data "Boosts" "UnlockSpell(Target_MAG_HealingWord);UnlockSpell(Shout_MAG_HealingWord_Mass)" This forces it to give us these spells. Note that the character needs spell slots in able to use them! If you want it for everyone you may be better off setting it up as a custom passive.
data "PassivesOnEquip" "MAG_Radiant_Radiating_Helmet_Passive;CUSTOMPASSIVEIMADE" (The ; seperates passives.)
data "Unique" "1" 
data "MinAmount" "1"
data "MaxAmount" "1" (These may cause you a headache if you put it multiple places, as they won't spawn for people who overlooked the first one. So I don't recommend using these!)

If adding a custom passive, your Passive.txt will look like this.

The example passive code is borrowed from Isobel's armor.

new entry "CUSTOMPASSIVEIMADE"
type "PassiveData"
data "DisplayName" "PASSIVEHANDLE1;1" (Generate a handle for this in your .loca file.)
data "Description" "PASSIVEHANDLE2;1" Generate a handle for this in your .loca file.)
data "Icon" "CUSTOMPASSIVEICON" (we can set this up in the same way an item icon is set up)
data "DescriptionParams" "DealDamage(1d4, Radiant)"
data "StatsFunctorContext" "OnAttacked"
data "StatsFunctors" "IF(context.HasContextFlag(StatsFunctorContext.OnAttacked) and HasStatus('MAGE_ARMOR') and IsLastConditionRollSuccess(ConditionRollType.ConditionSavingThrow) and not Self() and IsSavingThrow()):DealDamage(SWAP, 1d4, Radiant,Magical)"

Now, you need to put it in the treasuretable. Your treasuretable should look like this:

new treasuretable "TUT_Chest_Potions"
CanMerge 1
new subtable "1,1"
object category "I_MY_COOL_NEW_CIRCLET",1,0,0,0,0,0,0,0 (Do not forget the I_ prefix!)

This will make it spawn in the tutorial chest.
