Blip on low health

[Not_Wilson]

I'm trying to make a certain character blink red over and over ntil his health is brought up above a certain threshold. However, with the code I have, it'll only blink once and only when the health updates.

local function OnHealthDelta(inst, data)
    if data.newpercent <= .25 then 
--Blip for 1/5 of a second
	inst.AnimState:SetMultColour(1,.5,.5,1)
	inst:DoTaskInTime((1 *.5), function(inst) inst.AnimState:SetMultColour(1,1,1,1) end)
   
	elseif data.newpercent >= .25 then
	inst.AnimState:SetMultColour(1,1,1,1)
        end
    end
    
inst:ListenForEvent("healthdelta", OnHealthDelta) --This goes in master_postinit

Is there away to make a stategraph, by chance?

Got it.

If you want the code, here you go in case if you wanna make it obvious that a character is low on health. Thank you @Neutral_Steve for the help.

Slap this in above common_postinit

local function DoPain(inst)
						--   R G B A
inst.AnimState:SetMultColour(1,.25,0,1)
    inst:DoTaskInTime((1/2 *.5), function(inst) inst.AnimState:SetMultColour(1,1,1,1) end)
end

local function OnHealthDelta(inst, data)
    local health = inst.components.health:GetPercent()
    if health <= .25 and not inst:HasTag("hascurrentpain") then 

    inst.task = inst:DoPeriodicTask(1/2, DoPain)
    inst:AddTag("hascurrentpain")

    elseif health >= .25 then
    if inst.task ~= nil then
        inst.task:Cancel()
    end
    inst:RemoveTag("hascurrentpain")
    inst.AnimState:SetMultColour(1,1,1,1)
        end
end

Put this in onbecamehuman(inst) and master_postinit

	inst:ListenForEvent("healthdelta", OnHealthDelta)

and onbecameghost(inst)

   inst:RemoveEventCallback("healthdelta", OnHealthDelta)
