Attempt to index boolean with 'Changed'

[DragonDarkYin]

So i have been trying to prevent code being executed until my character lands. So i used a function to return a true or false value to determine this

local function IsJumpingListener(Humanoid)
	local landed  = false
	humanoid.StateChanged:Connect(function(OldState,NewState)
		if NewState == Enum.HumanoidStateType.Landed then
            landed = true
		else
			landed = false
		end
	end)
	return landed
end

Then i would use this code to wait till the character lands, however

 if not IsJumpingListener(humanoid) then IsJumpingListener(humanoid).Changed:Wait() end

I kept on getting this error

Any solutions? thanks

The reason this is happening is because in that function you’re returning the landed boolean, not the event. Try this:

 if not IsJumpingListener(humanoid) then repeat wait() until IsJumpingListener(humanoid) end

I’ve heard that we should avoid using that wait

Avoiding wait() and why

This is an adaptation of a Twitter thread I made a while ago. This is simply a better formatted and more fleshed out version. Let’s talk about wait(). Not wait(n) (although if you are using small n values to where it’d be barely distinguishable from wait(), you’re probably going to hit the same issues mentioned in this thread). We probably learned about wait() at first as the solution to “why are my infinite loops crashing me?”. It’s a super easy solution and it works! This starts a bad habit…

Any alternative

It’s not the most efficient solution, but it’ll work.
You can also use RunService.Heartbeat, or make something similar to the thread you linked

Ok so the error stops coming but the code that I initiate after does not work properly

thanks for your help though

I fixed the problem my self, just ended up shooting an event every time my character is in the landing state
