[How to modify the damage of assasin class when its get critical?]

In additional, this snippet

 

if((sd->class_&MAPID_UPPERMASK) == MAPID_ASSASSIN)

 

will cause a fatal error an.d bring the map server down because when critical event cause by a monster a sd pointer will given a null and server will be crashed with pagefault

 

to prevent this we have to check that if sd is null or not first

 

if(sd && (sd->class_&MAPID_UPPERMASK) == MAPID_ASSASSIN)

 

and this line should works well

Thank you poporing. It works

[How to modify the damage of assasin class when its get critical?]

I found something in battle_calc_base_damage funciton in file battle.c

static int battle_calc_base_damage(struct status_data *status, struct weapon_atk *wa, struct status_change *sc, unsigned short t_size, struct map_session_data *sd, int flag)

 

and this snippet

 

//Weapon Damage calculation

if (!(flag&1))

damage = (atkmax>atkmin? rand()%(atkmax-atkmin):0)+atkmin;

else 

damage = atkmax;

 

This snippet is seperate a critical hit and non-critical hit damage and i want to modify it, when assasin class (assasin, assasin cross, baby assasin) make critical damage. It will be multiple with 1.5 or 2.

 

 

But i didn't know how to get the character class to check if condition is met. Im not sure that map_session_data contains any properties that refer to the class of damage dealer (Maybe sd->class_  ??) and if what i think is correct how do i compare to the 3 class that i mention above.

 

Please help, and sorry for my english mistake i am not a native speaker.
