How would I script an oxygen bar by reading terrain voxels?

Here’s the output I don’t see anything regarding the oxygen script

#23

It says there was an error on line 23 of a server script, that is also unrelated right?

#24

I realized I had an error in the server script, can you recopy and paste that code and see if it works now?

This is the result that I got:

Maybe just replace the local script code with this?

local player = game.Players.LocalPlayer

local background = script.Parent
local Bar = background:WaitForChild("Bar")
local OxygenText = background:WaitForChild("OxygenText")

OxygenText.Size = UDim2.new(1,0,1,0)

local oxyValue = player:WaitForChild("OxygenValue")

while wait(0.3) do
	Bar:TweenSize(UDim2.new(player.OxygenValue.Value/1000,0,1,0), "Out", "Quad", 0.3)
	OxygenText.Text = "Oxygen "..player.OxygenValue.Value.."/1000"
end

I get this error message for the server script

#26

Try replacing the server script with this:

game.Players.PlayerAdded:Connect(function(player)
	local oxygen = Instance.new("IntValue", player)
    oxygen.Value = 1000
    oxygen.Name = "OxygenValue"
	local increaseRate = 3 --how fast it increases
	local decreseRate = 2 --how fast it decreases
    local maxOxygen = 1000 --change accordingly

	while wait() do
		local char = player.Character or player.CharacterAdded:Wait()
		local castRay = Ray.new(char.Head.Position, Vector3.new(0,-10,0))
		local whiteList = {char}
		local hit, hitposition = workspace:FindPartOnRayWithIgnoreList(castRay, whiteList)
		local underwater = false
		if not hit then
			local castRay2 = Ray.new(char.Head.Position + Vector3.new(0,1000,0), Vector3.new(0,-1000,0))
			local hit2, hit2position = workspace:FindPartOnRayWithIgnoreList(castRay2, whiteList)
			if hit2 then
				underwater = true
			end
		end
		if underwater == false then
			oxygen.Value = math.clamp(oxygen.Value + increaseRate, 0, maxOxygen)
		else
			oxygen.Value = math.clamp(oxygen.Value - decreseRate, 0, maxOxygen)
		end
		print(oxygen)
	end
end)

this happens but the oxygen bar doesnt do anything
also the oxygen level doesnt go down either

#28

If you change the print to,

print(oxygen.Value)

Does the value change?

No it just prints the value of the oxygen

#30

Weird, it works for me. So this is in ServerScriptService?

yea its in server script service

#32

if its in a game try sending the link to the game and I can get the model from there

#33

This is the last thing I can think of that you could try for the server script. I am really confused though because it works for me. Are you using terrain water?


game.Players.PlayerAdded:Connect(function(player)
	local increaseRate = 3
	local decreseRate = 2
	local oxygen = Instance.new("IntValue", player)
	oxygen.Value = 1000
	oxygen.Name = "OxygenValue"
	wait(3)
		while wait() do
		local char = player.Character or player.CharacterAdded:Wait()
		local castRay = Ray.new(char.Head.Position, Vector3.new(0,-10,0))
		local whiteList = {char}
		local hit, hitposition = workspace:FindPartOnRayWithIgnoreList(castRay, whiteList)
		local underwater = false
		if not hit or not hit:IsA("Terrain") then
			local castRay2 = Ray.new(char.Head.Position + Vector3.new(0,1000,0), Vector3.new(0,-1000,0))
			local hit2, hit2position = workspace:FindPartOnRayWithIgnoreList(castRay2, whiteList)
			if hit2 and hit2:IsA("Terrain") then
				underwater = true
			end
		end
		if underwater == false then
			oxygen.Value = math.clamp(oxygen.Value + increaseRate, 0, 1000)
		else
			oxygen.Value = math.clamp(oxygen.Value - decreseRate, 0, 1000)
		end
	end
end)
