How would I go about making a aimlock script?

Help and Feedback Scripting Support
#1

So i’m adding a abilities to my game and i’m trying to add aimlock. I want it to be a function where I can activate it (locally) kinda like this:

function ActivateAimlock (duration <length that aimlock is activated>)
    while wait(duration) do
        for i,v in pairs(game.Players) do
            if v.Character.Magnitude <= 10 then -- I want it closest to mouse cursor
                Aimlock(v.Character.HumanoidRootPart)
            end
        end
    end
end

I tried but failed so i’m asking here. I’m just looking for a way to make the player Camera look at a object (through a function) to simulate aimlock.

Confused on how it initially activates, does it active when your mouse is over the target or when a key is pressed?

#3

Basically when right click is held down.

#4

Ah gotcha, when I made an lock on script which I’d say is the say is the same thing I used when E was pressed to activate it.

#5

I would do something like this:

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

function AimLock()
    local target
    local lastmagnitude = math.huge --just for the start
    for i,v in pairs(game.Players:GetPlayers()) do
        if v ~= player then
            if v.Character then
                local charpos = v.Character.PrimaryPart.CFrame.Position
                local playerpos = player.Character.PrimaryPart.CFrame.Position
                if (charpos - playerpos).Magnitude < lastmagnitude then
                    lastmagnitude = (charpos - playerpos).Magnitude
                    target = v
                end
            end
        end
    end
    if target and target.Character then
        local charpos = target.Character.PrimaryPart.CFrame.Position
        local cam = workspace.CurrentCamera
        local pos = cam.CFrame.Position
        workspace.CurrentCamera.CFrame = CFrame.new(pos, charpos) --I changed the CFrame right here.
    end
end
mouse.Button2Down:Connect(function()
    Aiming = true
    while Aiming do
        AimLock()
        wait()
    end
end)

mouse.Button2Down:Conenct(function()
    Aiming = false
end)

So to summarize it, set the position of the camera as the position of the camera (to not glitch it) and the rotation to where the enemies player’s position is (I added it so it would locate the closest enemy). If you need to understand better, I will mark where I changed the CFrame of the camera.

EDIT: I started writing this before I saw @sniper74will 's reply.

It’s possible, but would not necessarily consider this trivial.

First, you must set the Camera.CameraType to "Scriptable". Once you do this, you have complete control over the Camera, which means you must now code the behavior of the Camera manually. You can change it back to "Custom" once you are done with your lock mode.

Next, you must figure out your subject. Who do you want to target? You want to get their Player.Character model and then from there, save a reference to one of their body parts so you can use below. Looks like you want the player closest to your Mouse. You can use Mouse.Target.p to get the position of the Mouse in 3D space, then do some math to get the closest one to your Mouse.

BTW, you can get the mouse using game.Players.LocalPlayer:GetMouse().

Next, you have to do some CFrame math. You want to set the Camera.CFrame to the Position of your character, rotate the camera in the correct direction, then cframe again to offset the camera to where it’s above and behind your head. All of this should be done in a while loop or, more preferably, a RunService.RenderStepped event.

Can you tell me how to make it lock on by closest to mouse cursor and not distance?

#8

That would be a little glitchy, but I can do that.

Here is the revised script:

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

function AimLock()
    local target
    local lastmagnitude = math.huge --just for the start
    for i,v in pairs(game.Players:GetPlayers()) do
        if v ~= player then
            if v.Character then
                local charpos = v.Character.PrimaryPart.CFrame.Position
                local mousepos = mouse.Hit.p
                if (charpos - mousepos).Magnitude < lastmagnitude then
                    lastmagnitude = (charpos - mousepos).Magnitude
                    target = v
                end
            end
        end
    end
    if target and target.Character then
        local charpos = target.Character.PrimaryPart.CFrame.Position
        local cam = workspace.CurrentCamera
        local pos = cam.CFrame.Position
        workspace.CurrentCamera.CFrame = CFrame.new(pos, charpos) --I changed the CFrame right here.
    end
end
mouse.Button2Down:Connect(function()
    Aiming = true
    while Aiming do
        AimLock()
        wait()
    end
end)

mouse.Button2Down:Conenct(function()
    Aiming = false
end)

This SHOULD work, but I’m not sure.
