Both of you, thank you for the advice!
I have decided to check from
Achievement.
For
IsSmithingStyleKnown(styleItemIndex, patternIndex),
I tried specifying
craftingType(CRAFTING_TYPE_BLACKSMITHING / CRAFTING_TYPE_CLOTHIER / CRAFTING_TYPE_WOODWORKING)
but I
gave it up.
The source code is almost completed, so it is under test.
UI design sense is poor, so it's a very simple UI ,,,
