Oxygen bar

[lusty garnet]

I'm having trouble figuring out how to tell when a players head is above the water. Currently the way my script works is just by detecting if the player is swimming. The player can't swim to the surface for air though with this system. Any suggestions on what I could try?

if you know the height of the water, you can track if the player's head is close enough

local bar = script.Parent.BarBG.Bar
local oxygenLabel = script.Parent.BarBG.OxygenAmount

local maxOxygen = 100
local currentOxygen = maxOxygen

local timePerLoss = 0.3
local timeToWait = 1

local isSwimming = false

local char = game.Players.LocalPlayer.Character
local hum = char:WaitForChild("Humanoid")
local head = char:WaitForChild("Head")


while wait(timeToWait) do
    if head.Position.Y < 255 then

        isSwimming = true
        print("swimming set to true")
    else
        isSwimming = false
        print("swimming set to false")
    end
end

while wait(timePerLoss) do
    print("second while started")

    if isSwimming == true then

        currentOxygen = math.clamp(currentOxygen - 1, 0, maxOxygen)

    else
        currentOxygen = math.clamp(currentOxygen + 1, 0, maxOxygen)
    end


    if currentOxygen < 1 then

        hum.Health = 0
    end


    local barScale = currentOxygen / maxOxygen
    bar:TweenSize(UDim2.new(barScale, 0, 1, 0), "InOut", "Linear", timePerLoss)

    oxygenLabel.Text = currentOxygen .. " / " .. maxOxygen
    print("level set")
end

if you want to make it even more realistic you can offset the place of the head your tracking

for some reason, the second while statement doesnt run at all

[rustic panther]

i.e closer to the nose for exmaple

[rustic panther]

cause the first while statement is running 😅

oop im a noob

[rustic panther]

remember scripts are one lane 🙂

[lusty garnet]

so essentially one while per script?

[rustic panther]

they execute logic in order

nope you can do stuff to have multiple loops per script

like using task.spawn to create a new pseudo thread

task.spawn(function()
  while task.wait() do

  end
end)

print("this will print")

  while task.wait() do

  end

print("this will NOT print")
