Forum :: Programming :: Stackable Buffs Turorial! o.o

This here is an attempt to make a tutorial on how to add stackable stat buffs to your server code. Hope you like it. ;o

-First, we need to go to Character.hpp and find:

class Character : public Command_Source

-Put this above it:

struct Character_StatBuff

{

    std::string label;

    int time;

    short str;

    short intl;

    short wis;

    short agi;

    short con;

    short cha;

};

-Now we need to put something in the class. Find this:

class Character : public Command_Source

{

public:

-Put these anywhere under it (I like to keep my variables and prototypes seperate, but it doesn't matter):

std::list<Character_StatBuff *> statbuffs;

void UpdateStats();

bool Buff(std::string statname, int amount, int time, std::string label = "default");

void ClearBuffsLabeled(std::string label = "default");

void RemoveBuff(Character_StatBuff *thebuff);

void ClearBuffs();

-Ok, lets head off to character.cpp and find:

void Character::CalculateStats()

-Replace the entire function (assuming you know what a function is. o.o) with this:

-Now put all this junk above the function we just replaced:

https://tehsausage.com/paste/functions-and-such-ryouken

-Allright, lets go to world.cpp and find:

event = new TimeEvent(world_act_npcs, this, 0.05, Timer::FOREVER);

this->timer.Register(event);

-Put this below it:

event = new TimeEvent(world_timers, this, 1.0, Timer::FOREVER);

    this->timer.Register(event);

-Now for the last part, find:

void world_npc_recover(void *world_void)

-Put this above it:

https://tehsausage.com/paste/the-timer-o-ryouken

Thats all you have to do for the buff part. What you want to activate the buff is entirely up to you.

To activate a buff on a character, you simply put this line on code under whatever activates it:

character->Buff(<name of the stat|stats>, <amount>, <time>, <label string>);

The label is an optional thing you can put on the buff to identify it by incase you want to remove it later using this code:

character->ClearBuffsLabeled(<label string>);

Or if you just want to remove all buffs on the character, use this:

character->ClearBuffs();

The character pointer(character->) name varies depending on what function its in obviously, so it could be: from-> or this-> and sometimes other names.

Anyways, I'm sure this tutorial confused people more than helped them. ;.; But thats why I'm here to answer any questions. Please tell me if this works or not, because I had to remove a lot of stuff that my server uses from here, that way it wouldn't be cluttered. Also I may of missed a few thing. I'm pretty sure I got it all, but just incase. o.o

Very nice tutorial +1

okay i think i understand some of this, im just not sure what else needs to be done. xd

bool buffspell(x);
void clearbuffslabeled(x);
void clearbuffs(x);

x=spell id/buffid

that goes in character->public Command_Source?

(I get that i have to use different x values for each buff etc, just not writing everything out now.)

Hail Satan!

I'm confused, o.o what have you added so far? I'm not sure what you're having trouble with. ;o

I'm not, I dont even have eoserv downloaded, I'm asking you if I'm interpreting everything correctly.
