Highlight not highlighting

Help and Feedback Scripting Support
#1

I am making a script where when I equip the tool it heals the player and highlights them for a split second, but it returns the error ‘Attempt to connect failed: Passed value is not a function’

script.Parent.Equipped:Connect(function()
	script.Script.Enabled = true
	local char = script.Parent.Parent
	local highlight = Instance.new('Highlight')
	highlight.FillColor = Color3.new(0, 1, 0.0823529)
	highlight.OutlineColor = Color3.new(0, 1, 0.0823529)
	highlight.FillTransparency = 0
	highlight.Enabled = true
	highlight.Parent = char
	script.Sound:Play()
	wait(0.2)
	highlight:Destroy()
	wait(0.2)
	script:Destroy()
end)

the error is in this script on line 162

#7 
local hum = script.Parent.Parent:FindFirstChild('Humanoid')
hum.Health = hum.Health + 30
script:Destroy()

and this is the disabled script with an error saying ‘Attempt to index nil with ‘Health’’ on line 2

#8

I can’t see any functions called EventActive in the code you sent.
It’s likely that you either have defined it as something else (such as a boolean value), or just haven’t defined it at all, causing the error

That error means that the humanoid doesn’t exist. People usually get around that by doing

if hum then
    -- damage them
end

Check that the path makes sense for accesing the player’s humanoid

right i forgot to remove that…

#11

how about the highlight? it’s my main problem currently

#12

You might want to try to get the player from character then get the character again from the player you got. (longer steps i know)

Here is an example of how you can do it:

tool.Equipped:Connect(function()
    local player = game.Players:GetPlayerFromCharacter(script.Parent.Parent)
    local Char = player.Character
end)
#13

Is it parented to the player’s character even?

#14

is this inside a tool? you might wanna do a check for the tool being equipped
