NPC that runs away from nearest player

Hi!
I wanna make an NPC that runs away from a nearest player.
So my code isn’t working, cause I don’t know how to make that

Current Code:

function checkTorso()
	local torso
	for _,v in pairs(workspace:GetChildren()) do
		if v:FindFirstChild("Humanoid") and v.Name ~= script.Parent.Name then
			local temp = v:FindFirstChild("Torso")
			if (script.Parent.Torso.Position - temp.Position).Magnitude < 30 then
				torso = temp
			end
		end
	end
	return torso
end

while wait() do
	local torso = checkTorso()
	if torso then
		script.Parent.Humanoid:MoveTo(Vector3.new(torso.CFrame.LookVector * -25, 0, torso.CFrame.LookVector * -25))
	end
end

I’d recommend just looping through GetPlayers instead of having to find the players.

You’ll also need to use HumanoidRootPart instead, as R15 has UpperTorso but both R6 and R15 have a HRP.

function checkHRP()
    local closest 
    local closestMagnitude = 30
    for _, player in pairs(game:GetService("Players"):GetPlayers()) do
        if player.Character then
            local hrp = player.Character:FindFirstChild("HumanoidRootPart")
            local hrpMagnitude = hrp and (script.Parent.Torso.Position - hrp.Position).Magnitude or math.huge
            if closestMagnitude >= hrpMagnitude then
                closestMagnitude = hrpMagnitude
                closest = hrp
            end
        end
    end
    return closest
end

--now you can loop and run away if it finds one

Okay, now how do I get the NPC to run away from closest

that will find the closest, you just need to call the function

local runAwayDistance = 10

function checkHRP()
    local closest 
    local closestMagnitude = 30
    for _, player in pairs(game.Players:GetPlayers()) do
        if player.Character then
            local hrp = player.Character.LowerTorso
            local hrpMagnitude = hrp and (script.Parent.LowerTorso.Position - hrp.Position).Magnitude or math.huge
            if closestMagnitude >= hrpMagnitude then
                closestMagnitude = hrpMagnitude
                closest = hrp
            end
        end
    end
    return closest
end

while wait() do
	local torso = checkHRP()
	if torso then
		script.Parent.Humanoid:MoveTo((CFrame.new(script.Parent.LowerTorso.Position,torso.Position) * CFrame.new(0,0,runAwayDistance)).p)
	end
end

it’s not running from the nearest player because it only runs away from the player that is 30 studs away, so it doesn’t detect anything that’s over that.

Then just change the checkdistance, or just remove it completely. He wanted it to run away if a player was close, as you can see in his original code.

Aight, so other people have helped you clean up your code, but here’s the run down of what you need to do:

You need to have code that gets every player model in the game. After this, it loops through the list of player models, getting the distance from each player to the NPC. Now you know the closest player, so simply have it run away from their lookvector.

Code sample:

local ClosestPlayer
for i,v in pairs(PlayerList) do
    local Distance = (NPC.HumanoidRootPart.Position-v.HumanoidRootPart.Position).magnitude
    if ClosestPlayer then
          if (ClosestPlayer.HumanoidRootPart.Position-v.HumanoidRootPart.Position).magnitude > Distance then
               ClosestPlayer = v
          end
    else
          ClosestPlayer = v
    end
end

yeah, i just copied the scripts and changed the MoveTo line. because he was saying the MoveTo line didnt work.

#13

That’s what he said, the nearest player, not a player in the desired radius. Well, maybe it’s worded a bit wrong and I’m wrong.

#14

I get the confusion, but if you look at the script he provided as “Current Code”, it clearly says that if the player is closer than 30 units, then return that players torso.
