local function fernpick(inst, picker)
    if picker and picker.components.sanity and GetModConfigData("fernsanity") == ("true") then
        picker.components.sanity:DoDelta(TUNING.SANITY_TINY)
    else
        --No Sanity Reward
    end
end

AddPrefabPostInit("cave_fern", fernpick)

Your function in AddPrefabPostInit() is called when the prefab is spawned, and should tell the game how to edit the prefab's behaviour. You want to modify the fern's behaviour when it's picked, so you'll want to change the prefabs pickable component, which is what controls this action.

local function onpickedfn(inst, picker)
	if picker and picker.components.sanity then
		picker.components.sanity:DoDelta(TUNING.SANITY_TINY)
	end
	inst:Remove()
end

local function FernPostInit(inst)
    inst.components.pickable.onpickedfn = onpickedfn
end

AddPrefabPostInit("cave_fern", FernPostInit)

FernPostInit() is called when a fern is spawned into the world (via worldgen, loading or console) and it tells the game to override the onpickedfn function of the pickable component with your new onpickedfn.

Sadly as I tried it didnt change anything, althought thanks for the effort

It's working for me. I'm using the code in my previous post as the modmain.lua, and the code below as the modinfo.lua:

name = "Fern test"
description = ""
author = ""
restart_required = false
forumthread = ""
version = "1"
api_version = 10
dont_starve_compatible = false
reign_of_giants_compatible = false
dst_compatible = true
all_clients_require_mod = false
client_only_mod = false

In any case, do you receive any error message?

No, it only doesnt give any sanity on pickup and by any chance do you know how to check if its daytime? not twilight/night

Sorry, I don't know why that would be. Is the mod activated on the server? Other than that, I'm out of ideas. Maybe post the content of your modmain.lua and modinfo.lua so I (or someone smarter) can take a look at it?

Its enabled but Imma post the whole code anyway

I don't understand the code very well, but why this line is :

     inst.components.pickable.pickfern = pickfern

Shouldn't be :

    inst.components.pickable.onpickedfn = onpickedfn

Or at least

    inst.components.pickable.onpickedfn = pickfern

I was thinking that the "inst.components.pickable.onpickedfn" part is fixed by the game (by the pickable component) and that you can't change the name of it, no ? And if you want to start a custom function, you change the = nameofyourfunction, but not the first part ?
 

(Sorry if i'm wrong, i'm just trying to understand how it works)

Yes you were right, thanks a lot for help!

Heads up, your mod will crash for clients. Add these lines

if not GLOBAL.TheWorld.ismastersim then
	return
end

to the beginning of your fernsets and flowersets functions.
