I was wondering how I could approach something like the topic I have created. I am planning on making this very advanced, adding certain commands that a specific user can do such as attacking a specific user, protecting a specific user, wedging on the user etc. I really have no idea how to go about this and I was wondering if anybody could give me some help. Any and all help is appreciated, thank you in advance! :smile:

P.S. you can ask questions below and I’d be happy to answer them.

For protecting a certain user from other players you could do a loop and make it detect players by using magnitude which could look something like this

local function getPlayerInRadius(player) --player would be the owner of the npc
    local radius = 5 --5 anyone within 5 studs
    local playerHrp = player.Character and player.Character.PrimaryPart

    if not playerHrp then
        return nil --no hrp exist so return nil
    end

    for i, targetPlayer in game.Players:GetPlayers() do
        local hrp = targetPlayer.Character and targetPlayer.Character.PrimaryPart

        if hrp then
            local distance = (playerHrp.Position-hrp.Position).Magnitude --gets the distance

            if distance <= radius then -- checks if the distance is within the radius and if it is returns the target player
                return targetPlayer
            end
        end
    end
end

This would return a player within 5 studs if you want it to return multiple players you could use a table and add players to that and return the table

Now for selecting a user to attack/protect, you could put a click detector in all players’ HumanoidRootPart, and when it’s pressed that becomes the target.

For moving the NPC you could use Pathfinding Service

For attacking a user, this depends on whether the NPC would have a weapon or not so I cannot currently help you on this without knowing more
Hope this helps sorry if anything is explained poorly

Thank you, I’ll have to look into this, I’m not too familiar with path finding service.
