How do I set up a function that waits for an event to fire but also returns a bool if it times out?
Say I wanted to add a "shield" to be depleted before health when a player takes damage, and said shield would regenerate on its own if no damage is taken in 10 seconds. How could I setup a function that waits a certain duration and returns true if the duration expires?
I read somewhere about using :wait() in this way but I have no idea how to have it return values.
function waitForChange(element, duration)
repeat until element.Changed:wait(duration) --Return false if event fires before duration
-- Return true if nothing fires
end
Sorry if the answer is actually really obvious, I'm very much a beginner at this.

What you could do is create a timer that counts down from 10 and is refreshed every time damage is taken, which would have to be tracked by a separate function.
I'll assume you're using a humanoid for this.
function waitforchange(shield, duration, humanoid)
currentHealth = humanoid.Health
local healthchangedevent = humanoid.HealthChanged:connect(function(health)
if health < currentHealth then
print("Shield damaged. Regeneration timer reset.")
duration = 10
end
currentHealth = health
end)
while shield do
while duration > 0 do
wait(1)
duration = duration - 1
print(duration.." seconds until shield regenerates.")
end
repeat humanoid.Health = humanoid.Health+5 wait(.1) until humanoid.Health == humanoid.MaxHealth or duration > 0
end
print("Shield destroyed!")
shield:Destroy()
healthchangedevent:Disconnect()
end
This script was not actually tested so if you find any flaws please message me. And no, the answer was not really obvious.
