Able to jump after JumpPower is set to 0

Help and Feedback Scripting Support

I have a detector server script for a part (located in the WS). It works sometimes, other times it doesn’t. It is supposed to, after the part is touched, sit the player down in a seat, which it does, the only problem is it does not change the jump power. I have tried changing to it a WaitForChild and regularly, it doesn’t work either times. If I try changing the WalkSpeed to 0 after a touch, it works good. Lastly, I tried what Roblox reccomends you do, use SetStateEnabled… that didn’t either. Is there something wrong with how I am locating the humanoid? Wouldn’t I get an message in the output?

script.Parent.Touched:Connect(function(hit)
	local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
	
	if plr then
		
		-- Find seat
		
		local truckSeats = script.Parent.Parent.Truck.Seats:GetChildren()
		
		for i, v in pairs(truckSeats) do
			if not v.Occupant then
				
				-- Seat the player in the seat
				
				v:Sit(plr.Character.Humanoid)

			-- This line below gives no error, it just doesn't work. 	plr.Character.Humanoid:WaitForChild("JumpPower").Value=0

				
				game.ReplicatedStorage.ShowExitGUI:FireClient(plr)
				
				break

			end
		end
		
	end
	
end)

edit: added comment to code for more clarity

Is UseJumpPower on the humanoid set to true?

Try this:


script.Parent.Touched:Connect(function(hit)
	local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
	
	if plr then
		
		-- Find seat
		
		local truckSeats = script.Parent.Parent.Truck.Seats:GetChildren()
		
		for i, v in pairs(truckSeats) do
			if not v.Occupant then
				
				-- Seat the player in the seat
				
				v:Sit(plr.Character.Humanoid)

		plr.Character.Humanoid.JumpPower = 0

				
				game.ReplicatedStorage.ShowExitGUI:FireClient(plr)
				
				break

			end
		end
		
	end
	
end)
