Changing Alchemist Marine Sphere Behavior

[Sylfeyn]

I'm trying to make the summoned Marine Sphere immediately cast Self Destruction upon spawning. What's the simplest way to achieve this, without affecting naturally spawned Marine Spheres?

Okay the simplest form was to create a separate mob based on Marine Sphere and edit the relevant source files to use its mob id instead of the original marine sphere, then configure the skill in mob_skill_db.txt with condition onspawn

which source files to edit to use different mob id?

I created a mob with id 30000 and AegieName G_MARINE_SPHERE in db/import/mob_db.yml all other stats copied from the original
Then I added this to db/import/mob_avail.yml to assign it a sprite:
 

Body:
  - Mob: G_MARINE_SPHERE
    Sprite: MARINE_SPHERE

In db/import/mob_skill_db.txt I added:
30000,Marine Sphere@NPC_SELFDESTRUCTION,idle,173,1,10000,3500,0,yes,self,onspawn,,,,,,,,

In skill.cpp:
 

case AM_SPHEREMINE:
case AM_CANNIBALIZE:
	{
		int32 summons[5] = { MOBID_G_MANDRAGORA, MOBID_G_HYDRA, MOBID_G_FLORA, MOBID_G_PARASITE, MOBID_G_GEOGRAPHER };
		int32 class_ = skill_id==AM_SPHEREMINE?MOBID_MARINE_SPHERE:summons[skill_lv-1];
		enum mob_ai ai = (skill_id == AM_SPHEREMINE) ? AI_SPHERE : AI_FLORA;
		struct mob_data *md;

I changed MOBID_MARINE_SPHERE to MOBID_G_MARINE_SPHERE.

Finally in mob.hpp:
 

enum MOBID {
	MOBID_PORING			= 1002,
	MOBID_RED_PLANT			= 1078,
	MOBID_BLUE_PLANT,
	MOBID_GREEN_PLANT,
	MOBID_YELLOW_PLANT,
	MOBID_WHITE_PLANT,
	MOBID_SHINING_PLANT,
	MOBID_BLACK_MUSHROOM	= 1084,
	MOBID_MARINE_SPHERE		= 1142,
	MOBID_EMPERIUM			= 1288,
	MOBID_G_PARASITE		= 1555,
	MOBID_G_FLORA			= 1575,
	MOBID_G_HYDRA			= 1579,
	MOBID_G_MANDRAGORA		= 1589,
	MOBID_G_GEOGRAPHER		= 1590,	
	MOBID_GUARDIAN_STONE1	= 1907,
	MOBID_GUARDIAN_STONE2,
	MOBID_SILVERSNIPER		= 2042,
	MOBID_MAGICDECOY_FIRE,
	MOBID_MAGICDECOY_WATER,
	MOBID_MAGICDECOY_EARTH,
	MOBID_MAGICDECOY_WIND,
	MOBID_ZANZOU			= 2308,
	MOBID_S_HORNET			= 2158,
	MOBID_S_GIANT_HORNET,
	MOBID_S_LUCIOLA_VESPA,
	MOBID_GUILD_SKILL_FLAG	= 20269,
	MOBID_ABR_BATTLE_WARIOR = 20834,
	MOBID_ABR_DUAL_CANNON,
	MOBID_ABR_MOTHER_NET,
	MOBID_ABR_INFINITY,
	MOBID_BIONIC_WOODENWARRIOR = 20848,
	MOBID_BIONIC_WOODEN_FAIRY,
	MOBID_BIONIC_CREEPER,
	MOBID_BIONIC_HELLTREE,
};

I added MOBID_G_MARINE_SPHERE    = 30000, into this enum

I think that's it.

ahh no wonder i got error. i didn't modify the mob.hpp file. thanks mate. but, 1 problem is, onspawn seems not working. when i spawned, it didn't cast the self destruction immediately. when i hit then only it will cast the skill. did yours working?

[Sylfeyn]

Yeah, mine is working.
Check your db/import/mob_skill_db.txt though and make sure you have a blank newline after the 30000,Marine Sphere@NPC_SELFDESTRUCTION,idle,173,1,10000,3500,0,yes,self,onspawn,,,,,,,, line
I remember the first time I saw an error in one of the servers when loading that file because it didn't count the correct number of arguments. Adding a new line made it work correctly.

yup, i did create a blank newline in the mob_skill_db.txt. no errors in the emulator. but somehow, i managed to make it work after recompile it again. weird, but got mine working now. thanks mate for the guide ^_^
