[NEED HELP] Coding: I want to make a character gradually lose health if it is at full sanity, and also to make the character spawning with half of its max sanity

[DeadlyFox]

I had been trying to find code lines that i could use as reference and trying to actually make the code myself but with no success for almost a week, if anyone could help me out i would be realy greatful.

Add this component to your player and let me know how it works. I made the threshold lower than 100% to fit visual ques, but you can tweak it to 1 again if you want.

Spoiler

STRINGS.NAMES.SHADOWBOUND_COMPONENT = "sanity" -- cause of death string

local function OnSanityDelta(inst, data)
	local self = inst.components.shadowbound
	self:CheckSanity(data.newpercent)
end

local function OnTimerDone(inst, data)
	local self = inst.components.shadowbound
    if data.name == "shadowbound" then
    	if not self.health then return end
		self.health:DoDelta(self.healthtick, nil, "shadowbound_component", false, nil, true)
		-- Rechecking sanity here would be redundant because OnSanityDelta is constant
    end
end

local ShadowBound = Class(function(self, inst)
	self.inst = inst
	self.inst:AddTag"shadowbound"
	self.threshold = 0.727 -- % sanity needed to activate decay (i picked this because thats when the brain shrivels but you can make it higher if you want
	self.healthtick = -1 -- health lost
	self.tick = 1 -- seconds to lose health
	if not inst.components.sanity then
		inst:AddComponent("sanity")
	end
	self.sanity = self.inst.components.sanity
	if not inst.components.timer then
		inst:AddComponent("timer")
	end
	self.timer = self.inst.components.timer
	if not inst.components.health then
		inst:AddComponent("health")
	end
	self.health = self.inst.components.health
	inst:ListenForEvent("timerdone", OnTimerDone)
	inst:ListenForEvent("sanitydelta", OnSanityDelta)
	inst:DoTaskInTime(0, function()
		self:CheckIfFirstTime()
		self:CheckSanity()
	end)
end)

function ShadowBound:CheckIfFirstTime()
	if not self.sanity or self.first then return end
	self.sanity:SetPercent(0.5, false)
	self.first = true
end

function ShadowBound:CheckSanity(percent)
	if not self.sanity then return end
	local percent = percent or self.sanity:GetPercent()
	if percent >= self.threshold then
		self:HealthDecayTask()
	end
end

function ShadowBound:HealthDecayTask()
	if not self.timer:TimerExists"shadowbound" then
		self.timer:StartTimer("shadowbound", self.tick)
	end
end

-- Basic saving/loading
function ShadowBound:Reset()
    self.first = nil
end

function ShadowBound:OnSave()
    return
	{
		first = self.first
	}
end

function ShadowBound:OnLoad(data)
	self.first = data.first or nil
end

return ShadowBound

 

If you want tips on what code to reference, I would recommend opening the command prompt and navigate to scripts and looking for things you want to add to components from there using grep or findstr. Scripts are bundled with your gamefiles. If you find a component command you want to use but are still stuck, it's useful to see commands used in action.

For this I had to look at the sanity, oldager, and health component for what I wanted.

I dont know if i am doing something wrong but now the game crashes wen i try to load the mod with the custom charcter now.

[oregu]

What's the error? Look at your Documents\Klei\DoNotStarveTogether in client_log.txt or master_server_log.txt and do ctrl + F "LUA ERROR" if the game closes

and also here is a screenshot in game if it helps

[oregu]

<eof> is do or then
The way you add components to put 
inst:AddComponent("componentname") in your player function (im guessing master_postinit for this one)
your component file must also be located in a file in scripts/components/componentname.lua in your mod folder so it can be found automatically. (so what i sent is its own file) if you are having trouble with STRINGS still or want to move them somewhere else you might need to do GLOBAL.STRINGS.

[oregu]

it's scripts/components/shadowbound.lua and AddComponent("shadowbound") for the component i sent you. 

if you want to rename a component it's best to replace every instance of the component name with your .lua file name and change AddComponent(name) to your component name.
the reason it throws an error is because i made the component name out of scope. line 5 would have to be local self = inst.components.componentname (i dont think you want a component named componentname though)
