Sanity based on proximity to other players

[FurryEskimo]

I have a character that excels at winter hunting, but is afraid to be alone, ensuring that the character doesn't wander off from the group.  I think I've managed to tag entities as "bestfriend" and generate a positive sanity aura based on time since a friend was nearby, but am having trouble testing it..  A lot of my conditional stats aren't activating, and the same goes for this one.  I think this code activates for all pig mobs, but I want it to tag followers and players.  I might rework it, to relate to players with low sanity, but I have no idea how to check for that.

local function FindFriend(inst)
    local x, y, z = inst.Transform:GetWorldPosition()
    local ents = TheSim:FindEntities(x, y, z, 3, {"pig"}, {"player","werepig","guard","bestfriend"})
    for k, v in pairs(ents) do
        if not v:IsAsleep() and not v.components.sleeper:IsAsleep() then
            if inst.components.leader:CountFollowers() >= 1 then return end
            if v.components.health and not v.components.health:IsDead() then
                inst:PushEvent("makefriend")
                inst.components.leader:AddFollower(v)
                v.components.follower:AddLoyaltyTime(240)
                v:AddTag("bestfriend")
                v:DoTaskInTime(480,function()
                    v:RemoveTag("bestfriend")
                    end)
            end
        end
    end
end

The post explains how to use the tags. If you don't want it to target pigs, why the pig-tag, then?

Parts of this code is pulled and edited from another mod.  That character made others sane when in proximity, but I want to make my own character's sanity influenced by proximity to players/followers.
