Question regarding the "produce" script command

[Bahmut]

Hello,

when using the produce script command there is a chance that it fails and no item is produced, but what is the exact success chance or how is it calculated?

There is no documentation on this. Atleast I found none. From script_commands.txt:

*produce <item level>;

This command will open a crafting window on the client connected to the invoking
character. The 'item level' is a number which determines what kind of a crafting
window will pop-up. You can see the full list of such item levels in
'db/produce_db.txt' which determines what can actually be produced.
The window will not be empty only if the invoking character can actually produce
the items of that type and has the appropriate raw materials in their inventory.

Valid item levels are:
1   - Level 1 Weapons
2   - Level 2 Weapons
3   - Level 3 Weapons
21  - Blacksmith's Stones and Metals
22  - Alchemist's Potions, Holy Water, Assassin Cross's Deadly Poison
23  - Elemental Converters

I created a new entry with a new item level in the produce_db.txt and so there is no skill to relate to:

7060,50,0,0,29101,1

EDIT:

Found it by searching the source and I have to say the skill_produce_mix function is very ugly. Default it's 50% success rate.

If you want to change it find this block in skill.c:

	   default:
			if (sd->menuskill_id ==	AM_PHARMACY &&
				sd->menuskill_val > 10 && sd->menuskill_val <= 20)
			{	//Assume Cooking Dish
				if (sd->menuskill_val >= 15) //Legendary Cooking Set.
					make_per = 10000; //100% Success
				else
					make_per = 1200 * (sd->menuskill_val - 10)
						+ 20  * (sd->status.base_level + 1)
						+ 20  * (status->dex + 1)
						+ 100 * (rnd()%(30+5*(sd->cook_mastery/400) - (6+sd->cook_mastery/80)) + (6+sd->cook_mastery/80))
						- 400 * (skill_produce_db[idx].itemlv - 11 + 1)
						- 10  * (100 - status->luk + 1)
						- 500 * (num - 1)
						- 100 * (rnd()%4 + 1);
				break;
			}
			make_per = 5000;
			break;

and change the last

make_per = 5000;

to

make_per = 10000;

for 100%

the same formula used by the skill "needed" for the desired item
