TheSim Entities help

[MF99K]

Hi guys, I'm trying to make a function that calls to the nearest entity with a specific tag on it, but I'm not sure how I need to phrase it. I know that TheSim:FindFirstEntityWithTag will work in some circumstances, but I really need nearest as opposed to first. TheSim:FindNearest and TheSim:FindClosest don't work so I'm wondering how to get this to work.

There has already been a built-in global function in simutil.lua, you can simply use it:

function GetClosestInstWithTag(tag, inst, radius)
    local x, y, z = inst.Transform:GetWorldPosition()
    local ents = TheSim:FindEntities(x, y, z, radius, type(tag) == "string" and { tag } or tag)
    return ents[1] ~= inst and ents[1] or ents[2]
end

    return ents[1] ~= inst and ents[1] or ents[2]
end

so 

TheSim:GetClosestInstWithTag("tag") would work for any prefab instance with that tag and apply to the nearest one? not just the prefab where that line of code is?

Which line of code are you referring to?

If you break down GetClosestEntityWithTag, you see that the only thing it is doing is find you all the entity with a specific tag in a radius around an origin point and return you the entity which is the closest to that origin (excluding the entity "inst" which is the one use to determine the origin point).

So it just looks for the tag and is not doing anything else.

so it would be GetClosestEntity and not GetClosestInst? I think I already tried GetClosestInst

I just made a typo. The function is the one ptr copy/pasted.

You said you tried it and it did not work? Could you post the function you used? What exactly did not work?

[MF99K]

local function RebindChester(inst, chester)
    chester = chester-- or TheSim:GetClosestInstWithTag("chester")--or TheSim:GetClosestEntityWithTag("chester")-- -- or TheSim:FindNearestEntityWithTag("chester")
    if chester ~= nil then
        OpenEye(inst)
        inst:ListenForEvent("death", function() StartRespawn(inst, TUNING.CHESTER_RESPAWN_TIME) end, chester)

        if chester.components.follower.leader ~= inst then
            chester.components.follower:SetLeader(inst)
        end
        return true
    end
end

 

note that all the different --TheSim lines are commented out, I'm only using one at a time when I test them, but none of the ones you see there work

You definitely misunderstood the usage of the function

It should be 

chester = GetClosestInstWithTag("chester", inst, 10000)

or for mods, it would be

chester = GLOBAL.GetClosestInstWithTag("chester", inst, 10000)
