Hi, I would need help programming an event after the death of a Boss (killer). I have tried many times in different ways but nothing. Could you help me? This is my code:

local boss = game.Workspace.UnknowBoss.Humanoid.Health

if boss == 0 then
	game.Workspace.rBrick.Position = Vector3.new(33.616, 1.699, 21.768)
end

Thanks!
