Mangos Coding

[adriann54]

I started to learn C++ and I know a little bit.

Is there any kind of tutorial on how to code this thing?

For Example :

if (!caster || caster->GetTypeId() != TYPEID_PLAYER)
return;

What of these things are doing?

( if isn't any caster or caster is not a player then return ? )

[VladimirMangos]

Exactly. Posible you look in some spell effect code that can be casted only by player caster

[caeruleaus]

first it's checking to make sure caster exists (not null because the next check would crash, or it would crash later) and then second it's making sure the thing casting the spell is a player or not. If the caster doesnt exist or the spell is being cast by something other than a player, the function ends and doesn't continue.

Ok, thank you...I'll try to learn these syntaxes

Edit:

Where Can I find all of those syntaxes ?

[Schmoozerd]

version 1) Copy and paste from examples, and if you don't understand something, do

www.google.com # C++ <NotUnderstoodClass>

version 2)

Buy a book

version 3)

www.google.com # C++ Introduction

Thanks for your friendly reply.

Even if didn't help me

I figured out by myself where I can find them

No tutoriel except this forum and some comment on the code.

Like you see knowing some language like C++ is not enought to fast understaind large project like Mangos. But with some reading and testing you/we/i can understaind more everyday

This is a pretty good site: http://www.cprogramming.com/tutorial.html

For example, you would learn about the ! operator here http://www.cprogramming.com/tutorial/lesson2.html functions here http://www.cprogramming.com/tutorial/lesson4.html and structs and the -> operator here http://www.cprogramming.com/tutorial/lesson7.html

i wonder why nobody did this on code:

if (Player* pCaster = dynamic_cast<Player*>(pUnit))
..

use C++ RTTI instead of custom type field?

[zergtmn]

dynamic_cast is slower than static_cast + typeid check.

[TheLuda]

Stackoverflow also has this one. Nice read if you are getting started.

[VladimirMangos]

In mangos we have special case also when typeid data required by client so we already have in any case typeid for object ready for checks

I tried to disable PvP in Dalaran ( which I think is a Sanctuary Area ), but I couldn't manage to disable it.

Original Player.cpp:

if(zone->flags & AREA_FLAG_SANCTUARY)                   // in sanctuary
   {
       SetByteFlag(UNIT_FIELD_BYTES_2, 1, UNIT_BYTE2_FLAG_SANCTUARY);
       if(sWorld.IsFFAPvPRealm())
           SetFFAPvP(false);
   }

Edited Player.cpp

if(zone->flags & AREA_FLAG_SANCTUARY)                   // in sanctuary
   {
       SetByteFlag(UNIT_FIELD_BYTES_2, 1, UNIT_BYTE2_FLAG_SANCTUARY);
       if(sWorld.IsFFAPvPRealm())
           SetFFAPvP(false);
       pvpInfo.endTimer = time(0);
   }

I also added : UpdatePvP(false);

Mangos uses vmaps for correct detection of areas. You have to enable vmaps in config.

[adriann54]

Upsiieee...my bad....I think I have forgotton to edit that in config files.

My vamps where extracted and assembled =D

I am sorry.

adriann54: cplusplus is a good website too... it has good tutorials and explains alot of stuff easy.
