Help on how to make a swimming system

[CVLM250 (tewg)]

Greetings developers! I have recently decided to start a project involving fishing, however, I have come across a problem.

I am currently trying to achieve a swimming system like minecraft’s swimming system, where you can float and if you press Ctrl you can swim with custom animations.
(Quick note: I am not using Roblox’s Water, I am using a part that represents the water.)

I have tried scripting on my own, it did not work, so I began searching though the forums, and the only good system that I was able to find was this one, and it would be a perfect fit, unfortunately, the creator has been terminated including his creations.

Any possible help would be great.

Have you considered making custom underwater movement using LinearVelocity?

[CVLM250 (tewg)]

I have never used LinearVelocity before, but I’ll give it a shot.

My only question is how would i control where the character is going?

[CVLM250 (tewg)]

Nope, couldn’t figure it out, I used VectorForce instead of LinearVelocity, and the character kept flying away when i tried to do so.

(edit)
Here’s my current code:

local runService = game:GetService("RunService")

local waterFolder = workspace.WaterInstances

local plr = game.Players.LocalPlayer
local char = plr.Character

local swimming = false

repeat
	task.wait(.1)
until plr and char

char.PrimaryPart = char:FindFirstChild("HumanoidRootPart")

local function checkWater()
	for i, v in pairs(workspace:GetPartsInPart(char.PrimaryPart)) do
		if v.Parent == waterFolder then
			return true, v
		end
	end
	return false, nil
end

runService.Heartbeat:Connect(function()
	local check, water = checkWater()
	if check == true then
		swimming = true
	--	print(check, water)
	end
	if swimming == true then
		
		if not char.PrimaryPart:FindFirstChild("VectorForce") then
			local attach = Instance.new("Attachment")
			attach.Parent = char.PrimaryPart
			local vectorForce = Instance.new("VectorForce")
			vectorForce.Attachment0 = attach
			vectorForce.Parent = char.PrimaryPart
		end
		--Character Keeps flying away when facing the camera
		char.PrimaryPart.CFrame *= CFrame.lookAt(workspace.Camera.CFrame.Position, char.PrimaryPart.Position)
	end
end)

Nevermind, i was able to figure it out myself.
