Hunger system

[vehuel]

I am investigating on how to create a hunger system where players need to eat constantly and increase the amount of food required while leveling up, it occurred to me to create a passive skill that is the "hungry" state, this will make the HP decrease until it is at 1 and the sp at 0, in addition to adding negative states; To counteract this ability I would like to create an active skill that lasts a certain amount of time disabling the hungry state, this skill must be activated with a consumable item. I would like you to help me and explain what I should do to build this system ... I already read the guide to add skill in the rathena wiki and I did not understand

I've been reading about states, so I think you can create 2 states, 1 hungry and one satisfied. does anyone have a guide?

Help! I have tried everything I see and I only manage to implement the system in an npc, when I implement it in a state, it activates the stone curse.
