Proximity Button wont kill after jumpscare, how to resolve?

local Jumpscare = script.Parent.Frame
local ClickPart = game.Workspace.SCP000Keyboard.ProximityPrompt
local JumpscareSound = script.Parent.SCP000JUMPSCARE
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:FindFirstChildOfClass("Humanoid")
Jumpscare.Visible = false
ClickPart.Triggered:Connect(function()
	Jumpscare.Visible = true
	JumpscareSound:Play()
	wait(1.3)
	Jumpscare.Visible = false
	if humanoid then
		humanoid.Health = 0
	end
end)

Try removing the if statement and are there any errors?? also on line 8 you can try filling in the () with (plr) It may help. Hope this helps!!

I believe its due to the fact that your character isn't updating after death. I've had this problem before as well and don't know why, as most people say it should be fine but if you simply add this somewhere in the script, preferably at the bottom it should work.

player.CharacterAdded:Connect(function(newCharacter)
character = newCharacter
end)

Also, killing someone from the client isn't the best approach, especially if the server sizes are greater than 1.
