아이템 조합 스크립트입니다.(별도로 데모는 첨부하지 않겠습니다.  SDK버전은 Near Fantastica의 SDK Test Bed에 들어있고, 스크립트 작동예시도 거기서 볼 수 있습니다)

  사용할 조합 레시피는
class Game_Temp
  def get_recipe_list
      ingredients = [33, 34] #조합에 사용할 아이템 ID
      ingredient_types = [0, 0] #조합에 사용할 아이템 타입(0:일반, 1:방어구, 2: 무기)
      quantities = [4, 1] #조합에 사용할 아이템 수량
      result = 4 #조합된 아이템 ID
      result_type = 2 #조합된 아이템 타입
      @recipe_list.push(Game_Recipe.new(ingredients,ingredient_types,quantities,result,result_type)) #조합메뉴에 나타날 조합 레시피
    ..........
  end
......
식으로 정의하면 됩니다.  이벤트로 레시피를 익히게 하려면
$game_party.learn_recipe([아이템ID,아이템타입])

메뉴나 맵에서 불러내려면
$scene=Scene_Craft.new
를 사용하면 됩니다.(기본적으로는 나갔을 때 메뉴로 돌아감)
