What do I do to disable jump for a few seconds when someone is forced to sit?

Here are two different methods on how to do it.

METHOD 1: Toggle the Humanoid's property, PlatformStand.

This will stop the user from moving or standing up, but upon testing you will see that the player is almost standing inside the ground.

ADVANTAGES:

• Handled through 1 script
• Simple
• Works

DISADVANTAGES:

• Player looks weird lol

local touchedBanana = false
local slipDelay = 3 -- how long before will be able to stand

script.Parent.Touched:connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
		if touchedBanana then return end
		local char = player.Character
		if char then
			local hum = char:FindFirstChildWhichIsA("Humanoid") 
			if hum then
				touchedBanana = true
				hum.Sit = true
				hum.PlatformStand = true
				delay(slipDelay,function()
					hum.PlatformStand = false
					touchedBanana = false
				end)
			end
		end		
    end 
end)

METHOD 2: Tell the client to disable player controls, taking away their power to stand. This way they can't move or do anything and are merely flopped until otherwise said

ADVANTAGES:

• Player will actually remain sat
• Efficient
• Works

DISADVANTAGES:

• Exploiters can reverse this
• Handled through 2 scripts

SCRIPT INSIDE BANANA

local touchedBanana = false

local bananaEvent = game:GetService("ReplicatedStorage"):FindFirstChild("BananaSlip") or Instance.new("RemoteEvent", game:GetService("ReplicatedStorage"))
bananaEvent.Name = "BananaSlip"

local slipDelay = 3 -- how long before will be able to stand

script.Parent.Touched:connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
		if touchedBanana then return end
		local char = player.Character
		if char then
			local hum = char:FindFirstChildWhichIsA("Humanoid") 
			if hum then
				touchedBanana = true
				bananaEvent:FireClient(player, slipDelay)
				hum.Sit = true
				delay(slipDelay,function()
					touchedBanana = false
				end)
			end
		end		
    end 
end)

LOCALSCRIPT INSIDE StarterPack

local bananaSlip = game:GetService("ReplicatedStorage"):WaitForChild("BananaSlip")

bananaSlip.OnClientEvent:Connect(function(t)
	local controls = require(game:GetService("Players").LocalPlayer.PlayerScripts.PlayerModule):GetControls()
	controls:Disable()
	delay(t,function()
		controls:Enable()
	end)
end)

If this works, please don't forget to accept my answer.
