If i use KeyFrameReached, and while the script is running, the animations gets stopped, will the script yield at the keyframe reached function?

nothing more than what the title says, i want to know this because this happened to me some time ago with getmarkerreachedsignal, and now i want to try keyframe reached.

forgot to add to the title, if the script is running and the animation gets stopped BEFORE the certain keyframe was reached

Yes, it will, and it is going to be resumed the next time it is reached.

Example:

-- Suppose this animation is longer than 1 second
task.spawn(function()
	animation:Play()
	animation.KeyframeReached:Wait() -- yield
	print("Reached when played again")
end)

task.wait(1); print("Stopping")
animation:Stop()
task.wait(1); print("Playing again")
animation:Play()

If this poses a problem, I have few solutions for canceling on top of my head:

1. Closing coroutines/cancelling threads

local thread = task.spawn(function()
	animation:Play()
	animation.KeyframeReached:Wait()
	print("Reached")
end)

task.wait(1); print("Stopping")
animation:Stop()
task.cancel(thread)

2. Promises (roblox-lua-promise by evaera) - relatively similar to point 1

3. Disconnecting connections

local connection = animation.KeyframeReached:Once(function(keyframe)
	print("Reached")
end)

animation:Play()
task.wait(1); print("Stopping")
animation:Stop()
connection:Disconnect(); connection = nil

im not really familiar with threads and task.spawn, is it possible to have keyframereached:connect(functiion) inside one of those?

I see you’ve marked the solution already, but just in case, sure, exactly like in the point 3, except :Once() is replaced by :Connect().

Don’t worry, coroutines are really not complicated, in the above cases they just wrap code and cancel the executed function later, so it doesn’t reach the end. Even the functions called in :Once() or :Connect() are ran in their own threads.
