just here is the code
(BTW this is a script and I know it should be working but it's not...)
game:GetService('Players').PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(charModel)
local hum = charModel:WaitForChild('Humanoid')
hum.Died:Connect(function()
hum:RemoveAccessories()
end)
end)
end)
Thank you
