[Guide] Adding custom Random Options

Introduction:

In this guide I will introduce you how to implement custom Random Options.

I will use as an example the bonus "bAddEff".

--------------------------------------------------------------------

- Server-Side -

First of all we will add our custom option to item_randomopt_db (db\import\item_randomopt_db.txt)

When opening this file will appear:

// Items Random Option Database    
//
// Structure of Database:
// ID,{ Bonus Script }

So we add this:

RDMOPT_WEAPON_FREEZE,{ bonus2 bAddEff,Eff_Freeze,getrandomoptinfo(ROA_VALUE)*100; }

In this case getrandomoptinfo(ROA_VALUE) is multiplied by 100, because 100 means 1% in bAddEff.

Also, we need to add the constant, opening db\const.txt.

Find:

"//RDMOPT_ATTR_TOLERACE_ALL    193"

And add below:

RDMOPT_WEAPON_FREEZE	194

Server side is finished~

--------------------------------------------------------------------

- Client-Side -

For display our custom options we must adding to enumvar.lub and addrandomoptionnametable.lub, located in (luafiles514\lua files\datainfo\)

Editing enumvar.lub:

Find:

ATTR_TOLERACE_ALL = { 193, 10 },

And add:

WEAPON_FREEZE = {194, 0},

*The first number must be same that added in const.txt*

 

Editing addrandomoptionnametable.lub:

Find:

[EnumVAR.MDAMAGE_SIZE_LARGE_USER[1]] = "Magical resistance Large size monster +%d%%",

And add:

[EnumVAR.WEAPON_FREEZE[1]] = "Freeze an enemy when attacking +%d%%",

%d% is equal to ROA_VALUE.

--------------------------------------------------------------------

After completing all of the above your Random Option is ready to use.

Remember that there is documentation of how to add random options to items and a sample npc.

If you have doubts, write on the comments.

cons = 

RDMOPT_CLASS_CHANGE     206

 

item_randomopt_db =

RDMOPT_CLASS_CHANGE,{ bonus bClassChange,getrandomoptinfo(ROA_VALUE)*100; }
