Custom spell/another class spell trainer

[RYUchan]

Hello WoW professionals!

Again I'm stuck attempting to customize my server.

Question

I want to add custom spells to trainer. Or use existing but from another class. So for instance Paladin class player could learn summon Imp. Ofcourse simple adding it to trainer NPC wouldn't show it in the list because it is Warlock spell. I looked through dbc files and through mangos db files but didn't figure out how to bypass this class restriction.

So can any customizing specialist advise me how to do it. Maybe there is another way to learn spell not through trainers?

I'm using Mangos 7808 + YTDB

Optional question

is there a working Mangos to Ascent db converter for 3.0.9? I really like mangos but there is alot more info on customizing for Ascent

Anyway this question is optional I really want to know the answer for the main one.

Thank you for your help in advance

That's only bypassable if you compile your own core. If you do, open NPCHandler.cpp (located in /src/game/ folder in source code) with notepad or any text editor and find (ctrl + F) this:

if(!_player->IsSpellFitByClassAndRace(tSpell->learnedSpell))
      continue;

Delete or outcomment those two lines and recompile. I don't know how the wow client will react on this but it should work fine.

I really like mangos but there is alot more info on customizing for Ascent

There is not much mangos info on this site, but you should take a look at the UDB Wiki, it has all information needed for DB customising.

Thank you for the answers.

I outcommented this lines but after recompilation nothing changed. Thats realy strange. Maybe there is another check somewhere :confused:

I added spells to the NPC trainer but there are visible to the corresponding class only.

[Dythzer]

I don't think there are more checks for this, not what I saw. It is possible that it's a client limitation.

[RYUchan]

I presume there are no ways to bypass client restriction? Or is it in the dbc files?

Also I was trying to add lockpicking to other classes and found this checks in Player.cpp

            if(_spell_idx->second->learnOnGetSkill == ABILITY_LEARNED_ON_GET_RACE_OR_CLASS_SKILL ||
                // lockpicking/runeforging special case, not have ABILITY_LEARNED_ON_GET_RACE_OR_CLASS_SKILL
                (pSkill->id==SKILL_LOCKPICKING || pSkill->id==SKILL_RUNEFORGING) && _spell_idx->second->max_value==0 )
            {

and

            if(_spell_idx->second->learnOnGetSkill == ABILITY_LEARNED_ON_GET_RACE_OR_CLASS_SKILL ||
                // lockpicking/runeforging special case, not have ABILITY_LEARNED_ON_GET_RACE_OR_CLASS_SKILL
                (pSkill->id==SKILL_LOCKPICKING || pSkill->id==SKILL_RUNEFORGING) && _spell_idx->second->max_value==0 )

I outcommented the lockpicking part and again nothing changed. I mean it is learned as a spell but not as an ability. And also again you can't see it from a custom trainer if you are not a rouge. Is it because there are another checks or is it client side restriction?

And again is it possible to bypass client side restriction?

[Dythzer]

outcommenting those checks will not make it work, they are used for other things.

If you do ".lookup skill lockpicking" after you have learned the pick lock spell you will see that the skill is learned ([known] tag), it's just not displayed in the skills window. For rogues it's added under the "Class skills" category in the skills window and skills under that category are most likely restricted to a specific class in the wow client. So basically the lockpicking skill grows server-side but not client-side.

And no you can't bypass client restrictions :/ Ofc server-side workarounds are always possible, but you can't make it show up in the skills window.

Lockpicking will still work though, so if you don't care about skills leveling you can set it to max for all players.

Yes I found out that learning lockpicking means learning spell 1804 and skill 633 but didn't really understand that it is client class restricted. So thanks for the explanation Oh well I'll give up with Lockpicking.

Also I was thinking about walkarounds for spells...
Is it possible to make a quest where you can give money and NPC will teach you a warlock summoning skill(for example) as a reward. If it is possible could you give some tips on it. I looked through quest_template but didn't understand how to make this idea working. The main problem is making money as an objective item.

Some time ago I was trying to break quest log max restriction and after digging through the core find something in QuestDef.h but again after recompiling it became a little buggy. WoW is really heavy client side restricted

[Dythzer]

I looked through quest_template but didn't understand how to make this idea working. The main problem is making money as an objective item.

Everything is explained here: Quest template - UDB, click on a field for info about it. Also, Quice makes quest editing in mangos much easier so you should try that

For money requirement use a negative value in the 'RewOrReqMoney' column (eg. '-5000' for a 5g requirement), and for spell learning you need to use the RewSpell column, the spell will be casted at quest completion so make sure to use a learn spell for this (they are tagged as [learn] when you do .lookup spell).

[RYUchan]

Yep thanks alot I figured out about money "- reward" but didn't get what was the learning spell part about. So thank you Dythzer I'll try this out.

Solved everything, just hacked into spell.dbc and create my own learning spells.
Again big thanks to Dythzer

Sorry to bother, but what exactly did you change to allow the other classes to use the spells?

[RYUchan]

@Shadowrun56
I didn't change anything in Trainers. Just made a walkaround - instead of trainers you got quests where you need to pay money to learn skill of you choice. The problem is that it is only possibble if a spell is a learning spell as Dythzer stated above, so you need to create your own learning spells.
