Best Way to Search for Humanoids?

[spartacraze (sparta)]

Hey so, I’ve made a hit detection system that uses Raycast, as you can probably assume by the title, When the cast hits a character, I get the exact part I hit (e.g. RightHand, RightLowerLeg, etc)

I know way to get the Humanoid from this while removing duplicate Humanoid’s but mine is kind of lengthy and janky lol.
(just a bunch of array sorting)

I’m wondering if there’s a known “best/efficient way” to filter the Humanoids out of the Raycast!

Thanks in advance for the ideas!

What I like to do is setting FilterDescendantInstances of the parameters to {Character}. This is the easiest way to exclude all character’s parts from raycasting as far as I know.

AFAIK each raycast can only hit 1 part, so I guess you’re asking how to find unique humanoids for a bunch of raycasts?

You can use a dictionary (hash map) to efficiently find unique values in a table:

function unique(t)
    local found = {}
    local unique = {}
    for _, v in pairs(t) do
        if found[t] then continue end
        found[t] = true
        table.insert(unique, v)
    end
    return unique
end

function findHumanoidsHitByRayCasts(rayCasts: {RaycastResult}): {Humanoid}
    local humanoids = {}
    for _, rayCast in rayCasts do
        local hit = rayCast.Instance
        local humanoid = hit.Parent:FindFirstChild("Humanoid")
        if humanoid then table.insert(humanoids, humanoid)
    end

    return unique(humanoids)
end

Wouldn’t this just filter out the everything the Raycast can hit though?

Yeah I’m just asking for the best way to get the humanoid from a bunch of random character parts after a bunch of raycasts!

This solution seems good, looks exactly like what I’ve been doing lol, glad to know I’m not just using some arbitrary way, thanks!

My bad, misunderstood the topic Glad that you found a solution though!
