how do I fix this custom health bar issue?
I got this code sample from an article on Roblox developer:
- https://developer.roblox.com/en-us/articles/Making-a-Unit-Frame
here is the code, I basically copied everything perfectly- other than changing the size and position
local player = game.Players.LocalPlayer
local unitFrame = script.Parent
local healthBar = unitFrame.HealthBarContainer.HealthBar
player.CharacterAdded:Connect(function(character)
local humanoid = character:WaitForChild("Humanoid")
humanoid.HealthChanged:Connect(function(health)
local healthPercentage = health / character.Humanoid.MaxHealth
healthBar.Size = UDim2.new(healthPercentage, 0, 1, 0)
end)
end)
I'm thinking maybe this is outdated? what should I change?

Wouldn't it be local healthPercentage = character.Humanoid.MaxHealth - health Warriorfoox 25 — 5y

no that would be how much health is remaining. If i have 50% of my health left I want 50% of the bar to be filled, which is what divide currentHealth by maxHealth does Spiritlotus 151 — 5y

Use this for reference point to: https://developer.roblox.com/en-us/api-reference/event/Humanoid/HealthChanged I think this will help you. Warriorfoox 25 — 5y

Unsure if I'm 100% correct here but I think the character is being added before the .CharacterAdded event is set up. This might be because GUIs and local scripts put in StarterGui only load after the character is loaded. You could try getting the character directly first and if it isn't nil, use that character.
This is what I did to fix it:
local player = game.Players.LocalPlayer
local unitFrame = script.Parent
local healthBar = unitFrame.HealthBarContainer.HealthBar
local function CheckHealth(character)
local humanoid = character:WaitForChild("Humanoid")
humanoid.HealthChanged:Connect(function(health)
local healthPercentage = health / humanoid.MaxHealth
healthBar.Size = UDim2.new(healthPercentage, 0, 1, 0)
end)
end
if player.Character ~= nil then
CheckHealth(player.Character) -- If the character is found, it runs the function and gives the character.
end
player.CharacterAdded:Connect(CheckHealth) -- If the character is nil or is respawning, this should run the function and give the new character once the character spawns.
Hope this helped! If you have any questions, just comment!

you could also just do:local character = player.Character or player.CharacterAdded:Wait() theking48989987 2147 — 5y
