Hello fellow gamers

I've been trying to make a custom character that can generate an invuln shield like thulecite crown with a chance on being hit, below is my code

local function OnAttacked(inst, data)
    if math.random(1,100)<=30 then
        local fx = SpawnPrefab("forcefieldfx")
        fx.entity:SetParent(inst.entity)
        fx.Transform:SetPosition(0, 0.2, 0)
        local fx_hitanim = function()
            fx.AnimState:PlayAnimation("hit")
            fx.AnimState:PushAnimation("idle_loop")
        end
        fx:ListenForEvent("blocked", fx_hitanim, inst)

        if not inst.components.health:IsDead() then
        inst.components.health:SetInvincible(true)
        end

        inst.active = true

        inst:DoTaskInTime(--[[Duration]] TUNING.ARMOR_RUINSHAT_DURATION, function()
            fx:RemoveEventCallback("blocked", fx_hitanim, inst)
            fx.kill_fx(fx)
        inst.components.health:SetInvincible(false)
            if inst:IsValid() then
                inst.active=false
            end
        end)
    end
end

This currently doens't work in game based on my tests, can any modders figure out what is wrong?

Share your entire file for that but maybe you didn't call for it in the fn?
