I have this health GUI made by one of my friends, and i scripted it so that its like a health bar but it wont work and im not sure why.

heres the script

Code 
local dummy = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent
local hum =  dummy:WaitForChild("Humanoid")

local GUI = script.Parent


local endPos = UDim2.new(hum.Health / hum.MaxHealth, 0, 0, 19)

hum.HealthChanged:Connect(function(dmg)
	GUI.Size = UDim2.new(hum.Health / hum.MaxHealth, 220, 0, 17)
end)

help and feedback is appreciated :smiley:

Would there happen to be any errors on your Output at all? That would help out a lot (You can find it on the top within View > Output)

there are no errors in the output. i told the script to print something but nothing was printing either :sweat_smile:

Are you damaging the dummy through a server script or a local script?

Could be issue be happening somewhere else then? Try adding a print after you define your variables

print("WE KNOW THIS WORKS SURELY")

local dummy = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent
local hum =  dummy:WaitForChild("Humanoid")

local GUI = script.Parent

print("Maybe there isn't a Humanoid in the 7 Parents you referenced?")

local endPos = UDim2.new(hum.Health / hum.MaxHealth, 0, 0, 19)

hum.HealthChanged:Connect(function(dmg)
    print("Detected change")

	GUI.Size = UDim2.new(hum.Health / hum.MaxHealth, 220, 0, 17)
end)

Is it a LocalScript? If so, the code’s not running at all because LocalScripts don’t run while parented under any descendant of the Workspace.

The issue was most likely caused from the 220 offset in the UDim2, combining with the scale messing the entire thing. Also .HealthChanged returns the current health not damage:

--above code remains the same
local endPos = UDim2.new(hum.Health/hum.MaxHealth, 0, 0, 17)
hum.HealthChanged:Connect(function(health)
	GUI.Size = UDim2.new(health/hum.MaxHealth, 0, 0, 17)
end)
--also if 220 was an attempt to scale the bar, just do (health/hum.MaxHealth)*multiplier in scale. With multiplier being the aspect ratio(for example 5)

LocalScripts don’t work inside the workspace ( Lots of .Parents for the dummy model btw, I wonder what you put inside that dummy lol)

i found the solution, after looking through everyones comments i realized that the script should be in a local script, and that the offset value has to be 0.
