[Mod help] Sanity Perks

[PaladinPlayer]

Hello,

 

Thank you for stumbling upon this thread stranger!

 

I would like to add a sanity perk to my character but I don't know how to write code very we so here goes. The perks work like this;

She will have a small sanity gain when holding a bird and a slightly smaller gain when holding a feather. They are and simple but I do not know how to check for an item in an inventory.

 

Thank you for your help kind stranger!

@PaladinPlayer, I think putting this in the master_postinit for your character should do the trick:

local birds = {"robin", "robin_winter", "crow"}local function sanityfn(inst)	local hasbird = false	local hasfeather = false	for k,v in pairs(birds) do		if inst.components.inventory:Has(v) then			hasbird = true		end		if inst.components.inventory:Has("feather_"..v) then			hasfeather = true		end	end	return hasbird and TUNING.DAPPERNESS_SMALL or (hasfeather and TUNING.DAPPERNESS_TINY or 0)endlocal function master_postinit(inst)    inst.components.sanity.custom_rate_fn = sanityfn

I showed the master_postinit in there because it's better to have the sanityfn outside of it.

 

I made some assumptions about how you wanted this to work, here:

• Having multiple birds does not give you any additional sanity
• Having a bird negates any additional sanity from having feathers

There's probably a more efficient way to do this (something like listening for birds/feathers entering/leaving your inventory), but this should work, at least.

 Hi Rez!

 

Thanks (again) for the code it was very helpful since it worked perfectly!

Also while I look through more Modding Help pages I see your posts are always helpful which is awesome!

Your code worked perfectly up to a point but now it freezes/refuses to load/crashes and I don't know what to do please help this was such a nice feature before. P.S. I will do my best to provide info where it is needed but for now this is the prefab file I am using:   wilda.lua

@PaladinPlayer, Give us the crash log

[PaladinPlayer]

@rezecib

 

First of all I assume the crash log is in documents/klei/donotstarvetogether/log.txt

 

When sanityfn is here:

local birds = {"robin", "robin_winter", "crow"}

local function sanityfn(inst)

    local hasbird = false

    local hasfeather = false

    for k,v in pairs(birds) do

        if inst.components.inventory:Has(v) then

            hasbird = true

        end

        if inst.components.inventory:Has("feather_"..v) then

            hasfeather = true

        end

    end

    return hasbird and TUNING.DAPPERNESS_SMALL or (hasfeather and TUNING.DAPPERNESS_TINY or 0)

end

inst.components.sanity.custom_rate_fn = sanityfn

end

 

I get this crash:

and this log:log.txt

 

But when sanityfn is placed outside of master_postinit:

local birds = {"robin", "robin_winter", "crow"}

local function sanityfn(inst)

    local hasbird = false

    local hasfeather = false

    for k,v in pairs(birds) do

        if inst.components.inventory:Has(v) then

            hasbird = true

        end

        if inst.components.inventory:Has("feather_"..v) then

            hasfeather = true

        end

    end

    return hasbird and TUNING.DAPPERNESS_SMALL or (hasfeather and TUNING.DAPPERNESS_TINY or 0)

end

end

inst.components.sanity.custom_rate_fn = sanityfn

 

It will not load past this screen: 

and the log is:log.txt

 

P.S. Thanks for the help and sorry for the long post

@PaladinPlayer, Change both of the Has() to have ,1) at the end (e.g. Has("feather_"..v, 1) )

@rezecib,

This works well now thank you but the birds now give the same amount of sanity as the feathers.

 

[PaladinPlayer]

@rezecib, also she is a vegetarian but I wanted to add eggs to her diet so how would I go about doing that?

[rezecib]

@PaladinPlayer, Make a foodtype for the eggs and add it to her foodprefs. There are a ton of posts around on how to do that.

 

Hmm... As for birds/feathers, it should be working the way it is, I think, but we can try rewriting the "return" line as a few lines instead:

local delta = 0if hasfeather then delta = TUNING.DAPPERNESS_TINY endif hasbird then delta = TUNING.DAPPERNESS_SMALL end

But it may be working already, with the difference just not noticeable. Try changing the values, e.g. the SMALL to HUGE.

@rezecib,

Thanks again for all of your help! It works really well now and after a bit of food tweaking I think this mod is finished!
