How do you script the value of Humanoid Health?

For example, if the humanoid health's value is z, then something happens. This is my code: if health = 0 then this code doesn't work. How do I make this code work?

When your using conditional statements, only == is valid. You would most likely only use = if your changing the transparency or for ex: Thing.Transparency = Thing.Transparency - num.

This is the correct way to use the if statement with the humanoids health :

local p = game.Players.LocalPlayer
z = 0

if p.Character.Humanoid.Health == z then
print("humanoids health is at 0")

end

Try this.

local z = 0

if humanoid.Health == z then
	-- code
end

You use == for equals to and = for assigning values.
