Dragging physics like Lumber Tycoon 2?

It seems to be a pretty simple system. You've probably noticed the little blue sphere that appears at your mouse click point. From what I can see, it looks like that sphere is welded to whatever part you click on, at that point. The sphere then is given a BodyPosition and BodyGyro, which update to place the part in the correct direction and orientation.

So, we can keep a variable of the sphere and a function to create a unique one:

local dragSphere;

local function CreateDragger()
    if (dragSphere) then dragSphere:Destroy(); end

    dragSphere = Instance.new("Part", workspace); -- If FilteringEnabled is on, this could be a little more complex to implement
    dragSphere.Shape = "Ball";
    dragSphere.Size = Vector3.new(); -- Smallest size possible
    dragSphere.CanCollide = false;

    local bp = Instance.new("BodyPosition", dragSphere);
    bp.MaxForce = Vector3.new(10000, 10000, 10000);

    local bg = Instance.new("BodyGyro", dragSphere);
    bg.MaxTorque = Vector3.new(10000, 10000, 10000);

    return bp, bg;
end

Then, when the moues clicks something, we do something like:

    local distance = (mouse.Hit.p - characterPosition).magnitude;
    local bp, bg = CreateDragger();
    dragSphere.CFrame = CFrame.new(mouse.Hit.p);
    local weld = Instance.new("Weld");
    weld.Part0 = mouse.Target;
    weld.Part1 = dragSphere;
    weld.C0 = mouse.Target.CFrame:inverse() * dragSphere.CFrame;
    weld.Parent = dragSphere;
    local rotOffset = CFrame.new(characterPosition, mouse.Hit.p):inverse() * dragSphere.CFrame;

Once we've attached ourselves, we can do this every frame:

    bp.Position = characterPosition + (mouse.Hit.p - characterPosition).unit*distance;
    bg.CFrame = CFrame.new(characterPosition, mouse.Hit.p) * rotOffset;

Of course, a bit more implementation needs to be done to create a fully working system, but that's the main gist of it I think.

If you wanna see-able for other players w/ keybinding included but you have to make it so it inserts a sphere in

Keybindable Code: local player = game.Players.LocalPlayer local mouse = player:GetMouse() local camera = workspace.CurrentCamera local RunService = game:GetService("RunService") local target local down local Keybind = "E"

game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent) if inputObject.KeyCode == Enum.KeyCode[Keybind] then if mouse.Target.Name == "Grab" then if mouse.Target ~= nil and mouse.Target.Locked == false then target = mouse.Target mouse.TargetFilter = target down = true target.CanCollide = false target.Anchored = false

            local gyro = Instance.new("BodyGyro")
            gyro.Name = "Gyro"
            gyro.Parent = target 
            gyro.MaxTorque = Vector3.new(5000000, 5000000, 5000000)
            local force = Instance.new("BodyPosition") 
            force.Name = "Force" 
            force.Parent = target
            force.MaxForce = Vector3.new(100000000000, 100000000000, 100000000000) 
        end
    end
end

end)

game:GetService("RunService").RenderStepped:Connect(function() if down == true and target ~= nil then target.Gyro.CFrame = target.CFrame target.Force.Position = camera.CFrame.Position + (mouse.UnitRay.Direction * 5) end end)

game:GetService("UserInputService").InputEnded:Connect(function(inputObject, gameProcessedEvent) if inputObject.KeyCode == Enum.KeyCode[Keybind] then if target then if target:FindFirstChild("Gyro") or target:FindFirstChild("Force") then target.Gyro:Destroy() target.Force:Destroy() target.CanCollide = true target.Anchored = false end end down = false mouse.TargetFilter = nil target = nil end end)

NonKeybindable Code: local player = game.Players.LocalPlayer local mouse = player:GetMouse() local camera = workspace.CurrentCamera local RunService = game:GetService("RunService") local target local down

mouse.Button1Down:connect(function() if mouse.Target.Name == "Grab" then if mouse.Target ~= nil and mouse.Target.Locked == false then target = mouse.Target mouse.TargetFilter = target down = true target.CanCollide = false target.Anchored = false

        local gyro = Instance.new("BodyGyro")
        gyro.Name = "Gyro"
        gyro.Parent = target 
        gyro.MaxTorque = Vector3.new(5000000, 5000000, 5000000)
        local force = Instance.new("BodyPosition") 
        force.Name = "Force" 
        force.Parent = target
        force.MaxForce = Vector3.new(100000000000, 100000000000, 100000000000) 
    end
end

end)

game:GetService("RunService").RenderStepped:Connect(function() if down == true and target ~= nil then target.Gyro.CFrame = target.CFrame target.Force.Position = camera.CFrame.Position + (mouse.UnitRay.Direction * 5) end end)

mouse.Button1Up:connect(function() if target then if target:FindFirstChild("Gyro") or target:FindFirstChild("Force") then target.Gyro:Destroy() target.Force:Destroy() target.CanCollide = true target.Anchored = false end end down = false mouse.TargetFilter = nil target = nil end)
