Moisture to Speed ratio help. (perk)

[AudioFox]

I am currently making a character, and one of the attributes that I want is so that they slow down gradually with increased wetness. Here are some scripts that I have tried but don't seem to work. (I am looking for something that I can easily insert into the code)

	--local function GetSpeed(inst) --Moves slower the higher is wet, and slightly slower when raining.
	--local speed = (inst.wetness > 79 and -0.5) or
	--	   (inst.wetness > 39 and -0.5) or
	--	   (inst.wetness > 19 and -0.5) or
	--	   (inst.wetness > 4 and -0.5) or
	--	   0
	--	   
    --return inst.currentRain and speed - 0.5 or speed
--end

--local dapperness_onrain = -50 -- You can also use (-TUNING.SANITY_SMALL), or a custom value
--	local function rain_start()
--	inst.components.sanity.dapperness = dapperness_onrain
--	inst.components.locomotor:SetExternalSpeedMultiplier(inst, "character_speed_mod", 0.1)
--end
--	GetWorld():ListenForEvent("rainstart", rain_start)
--	local function rain_stop()
--	inst.components.sanity.dapperness = 0
--	inst.components.locomotor:SetExternalSpeedMultiplier(inst, "character_speed_mod", 1)	
--end
--	GetWorld():ListenForEvent("rainstop", rain_stop)

The code as a whole: 

local MakePlayerCharacter = require "prefabs/player_common"


local assets = {
    Asset("SCRIPT", "scripts/prefabs/player_common.lua"),
}
local prefabs = {}

-- Custom starting items
local start_inv = {"featherpencil"
}

-- When the character is revived from human
local function onbecamehuman(inst)
	-- Set speed when reviving from ghost (optional)
	inst.components.locomotor:SetExternalSpeedMultiplier(inst, "character_speed_mod", 1)
end

local function onbecameghost(inst)
	-- Remove speed modifier when becoming a ghost
   inst.components.locomotor:RemoveExternalSpeedMultiplier(inst, "character_speed_mod")
end

-- When loading or spawning the character
local function onload(inst)
    inst:ListenForEvent("ms_respawnedfromghost", onbecamehuman)
    inst:ListenForEvent("ms_becameghost", onbecameghost)

    if inst:HasTag("playerghost") then
        onbecameghost(inst)
    else
        onbecamehuman(inst)
    end
end

-- This initializes for both the server and client. Tags can be added here.
local common_postinit = function(inst) 
	-- Minimap icon
	inst.MiniMapEntity:SetIcon( "character.tex" )
end

-- Code Below, I added
local function runner(inst)
	if TheWorld.state.phase == "day" then
		inst.components.combat.damagemultiplier = 1
		inst.components.locomotor.walkspeed = (TUNING.WILSON_WALK_SPEED * 1.2)
	    inst.components.locomotor.runspeed = (TUNING.WILSON_RUN_SPEED * 1.3)
		inst.Light:Enable(false)
	elseif TheWorld.state.phase == "dusk" then
		inst.components.combat.damagemultiplier = 1.2
		inst.components.locomotor.walkspeed = (TUNING.WILSON_WALK_SPEED * 1.5)
	    inst.components.locomotor.runspeed = (TUNING.WILSON_RUN_SPEED * 1.6)
		inst.Light:Enable(false)
	elseif TheWorld.state.phase == "night" then
		inst.components.combat.damagemultiplier = 1.1
		inst.components.locomotor.walkspeed = (TUNING.WILSON_WALK_SPEED * 1.4)
	    inst.components.locomotor.runspeed = (TUNING.WILSON_RUN_SPEED * 1.5)
		inst.Light:Enable(true)
		inst.Light:SetRadius(6)
		inst.Light:SetFalloff(0.75)
		inst.Light:SetIntensity(.5)
		inst.Light:SetColour(70/255,230/255,14/170)
		end
	end
	
	--local function GetSpeed(inst) --Moves slower the higher is wet, and slightly slower when raining.
	--local speed = (inst.wetness > 79 and -0.5) or
	--	   (inst.wetness > 39 and -0.5) or
	--	   (inst.wetness > 19 and -0.5) or
	--	   (inst.wetness > 4 and -0.5) or
	--	   0
	--	   
    --return inst.currentRain and speed - 0.5 or speed
--end
	
	function SanityToWetness(inst)
	return (inst.wetness > 79 and -4 ) or -- -4 sanity per second while at 80 wetness or higher.
			(inst.wetness < 6 and -0.5) or -- -.5 sanity per second when at 5 wetness or below
			(inst.wetness < 21 and -1) or -- -1 sanity per second when at 20 wetness or below (but still above 5)
			 -2 -- -2 sanity per second when between 20 and 80 wetness.
end

Also thanks for taking your time to reply

Added Full code to character, Include (perk in title) (to help people that might want to help me) (added a lil comment at end)

[RedHairedHero]

The problem seems to be you have nothing calling/triggering your GetSpeed function.

 

 

[AudioFox]

Yeah, I figured that out. But I don't know what to trigger it with exactly.

[AudioFox]

Still would like to know how....

[. . .]

You can trigger you function like this in master_postinit

inst:DoPeriodicTask(1, GetSpeed)
