Help New Unique Skills (Buyable)

[`iAndre]

So , hello.
As the title says , i would like to know how can i create some new skills.

 

Infos
I want each character to have the right to "buy" 3 unique skills(max) from a custom npc only in level 80 and only in main class.
Ofc, they will have to pay with an item or something else in order to take the skills.

Also i would like to know how i will connect the core side of the skill with the client side.

Restictions

In order to be able to buy a skill , player should be noblesse and hero at least one time.
This skill won't be able to buyed by subclasses.

These skills can be used only from a player to each self (only for buff skills).
Players won't be able to use these skills in olympiad and events.

 

Regards,

`iAndre.

The connection between core and client side is made by ID, the one and only.

 

Let's start...

 

About client, you got 2 files, skillname-e.dat & skillgrp.dat. You create a new id, let's say 500, I like to work with small numbers, 500-600 are not used and you'll avoid database errors.

 

skillname-e.dat

 

500 1 a,Trance\0 a,This is my freaking description.\0 a,none\0 a,none\0

 

500 = id, 1 = level, "This is my freaking description" is obviously, 1st "none" is used for enchantable skills (e.g: +1 Power), or you can use it for another purpose, for example "GM Skill". 2nd "none" is the brother of the first, for example you can write "The power is increased."

 

skillgrp.dat

 

500 1 2 0 -1 0 0.00000000 0 icon.XD 0 0 0 0 -1 -1

level, id, type, mp consume, cast range, cast style, hit time, if it's magic and so on. You better look at the existing ones to understand, it's very easy.

My example is a little empty, because it's a passive, you don't need these options.

p.s. In case you create an active skill, you need to add skill animation too, not only the icon.

Let's move to the other side, xml.

 

 

<skill id="500" levels="1" name="Trance">
<set name="target" val="TARGET_SELF"/>
<set name="skillType" val="BUFF"/>
<set name="operateType" val="OP_PASSIVE"/>
<for>
<mul order="0x30" stat="runSpd" val="2" /> <!-- +100% speed because you're a GM, blah. -->
</for>
</skill>

This is quite easy, you probably have edited at least one skill in your life. This is a passive, if you want it to make ACTIVE, just add reuseDelay, hitTime and effect for buff time, stack order & type. As about debuffs and other, look at other existing skills.

3rd chapter is about your custom request, adding it as "learn skill".

You can take a look at my rebirth manager.

You gotta touch RequestAcquireSkillInfo, RequestAcquireSkill, L2NpcInstance and SkillTreeTable. Also to create a new class for the xml parser, just like my L2RebirthSkillLearn. And of course the xml for it, as my example: rebirth_skills_tree.xml

Sorry to inject into this post. Could you please tell me how to enable "Toggle Skill Animation" for skill icon? The same animation that you can see when turning 'Soul Cry' (ID 1001) skill on. Its icon gets special effect.

 

Does it have to be enabled client or server side?

 

Thanks
