How would I use magnitude to check if a player is near a tree for an axe script

Hello! I wanted to make a survival type game and I decided to start with making axes and trees and such. I’ve never used magnitude before and I wanted to know how I would use it to detect if a player is near a tree they clicked to chop it down with the equipped axe. If anybody could help me out of that or teach me how magnitude works that’ll be great! I’ve already checked the wiki and it kind of didn’t make sense to me, that is why I am asking. Thanks!

Magnitude is obtained when 2 Vector3 values subtract each other. So:

local result = (Vector3.new(5,8,192) - Vector3.new(9,7,5)).Magnitude

I see, so whatever is returned, is that a vector3 value, or studs, or something different?

It will return a number, defining the distance between 2 Vector3 values, in studs.

Alright cool, sorry if I am asking too many questions, but I am bad at math, how do you get a studs value?

Uh, what do your mean by this?

Give your Tree Model a PrimaryPart

local MagnitudeInStuds = (Tree.PrimaryPart.Position - Player.Character.HumanoidRootPart.Position).Magnitude -- Distance between player and the tree's primary part in studs

Basically Subtract 2 Vector3 Values aka Positions with each other in brackets, and put a .Magnitude behind to get the distance between both points.

Okay I’ll try that out, give me a second.

Try AxeTip part instead so it’s like more accurate.

put a local script inside the axe and write the following code :

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

mouse.Button1Up:Connect(function()
    if mouse.Target.Name == "Log" then --change log to what should mouse be on to be activated
        local distancebetweenpos = (player.Character.HumanoidRootPart.Position - mouse.Target.Position).Magnitude
        local distance = 10 --change 10 to required distance to cut
        if distancebetweenpos <= distance then
            local target = mouse.Target.Parent
            game.ReplicatedStorage.CutTree:FireServer(target)
        end
    end
end)

Now a script inside the serverscriptservice

game.ReplicatedStorage.CutTree.OnServerEvent:Connect(function(player, target)
    -- do stuff
end)

I think that’s all

This is not a good way to scrip it, exploiters can already exploit it.

Ok so then make a anti exploit

Thanks for that, but that seems really easy to exploit it. I think I know of a way to make it somewhat exploit resistant, so I need to script it. It will take a bit.

What are you talking about? This category is not for asking full scripts. Please note that that’s a rule on devforum.

Oh sorry i think i forgot the rules ill read them again

Extra tip: use a RunService.Heartbeat event on the server to constantly check the distance between each player and the tree so the script will make sure whoever is the near the tree will have the permission to chop the tree.

Won’t be really efficient since I’m going to put a bunch of trees. I’m just going to check the distance from the player to the tree they clicked. And that will be checked on the server so hopefully exploiters cant mess with it.

That will result in inefficiency, instead just check the distance in client and server when they Fire the Chopping Event, and not a Heartbeat Connection.

No no no, it’s an alternative of while true loop.
