-- Deals poison damage.

end

local function onattackother(inst, data)
if data.target and data.target.components.health and not data.target.components.health:IsDead() then

-- No target players.
if not data.target:HasTag("player") then

-- Can't already be poisoned.
if data.target.poisontask == nil then

-- If conditions met; deal DoPoisonDamage value 3 times per second.
data.target.poisontask = data.target:DoPeriodicTask(1/3, DoPoisonDamage)

-- End poison damage @ 30 seconds. Deals 90 damage total.
data.target.poisonwearofftask = data.target:DoTaskInTime(30, function(inst) inst.poisontask:Cancel() inst.poisontask = nil end)

        end
    end
end

Okay, so this simply is some poison code I've been testing thanks to a friend. It's not strong initially but can cause the player to deal over a hundred damage with their bare fists over time, plus weapons increase the initial damage. My main issue, however, is that you can't see that damage is being dealt. Is there any way to either make an enemy flash a pink-purple when they take a damage from this or make an enemy turn pink-purple shaded until the effect is over? Either one works, I just want to know that they're still taking damage. Is there any way that is somewhat easy to do this? I couldn't think of any and figured the forums would be a bit more help than trying to study it myself.

Thanks! Peace out.

Calling on @DarkXero if he knows the answer, or @Mobbstar since you guys are generally the most helpful. I just need a way to make the poison change their color; would there be a way, perhaps, to set a light on them with no radius or brightness, so that they just turn purple without glowing? If not, what do you guys recommend?

You could try this, each time it should do a tick of damage:

	data.target.AnimState:SetMultColour(1,0,1,1)
	data.target:DoTaskInTime(.3, function(inst) inst.AnimState:SetMultColour(1,1,1,1) end)

That should make the afflicted target blip purple for .3 seconds.

Could also look into using AnimState:SetAddColour in combination and changing the values around to get the exact color you want.

@Squids Where would I put that? I kinda understand code but I don't want to put it in the wrong place.

[Squids]

In your DoPoisonDamage function, so I suppose it would go like this:

local function DoPoisonDamage(inst)
	inst.components.health:DoDelta(-1, true, "poison")
	inst.AnimState:SetMultColour(1,0,1,1)
	inst:DoTaskInTime(.3, function(inst) inst.AnimState:SetMultColour(1,1,1,1) end)
end

That's working! Thank you very much! I did have to tweak it to 1/9 instead of .3 cuz it wasn't flashing consistently. It's perfect now! Muchos gracias.

[Squids]

No problem. Yeah I noticed after posting that your poison ticks every .33 and realized it would almost look permanent flashing at .3. Glad it's working though.
