How do I make a proper/realistic bounce pad?

Bounce pads can be made simply by using Humanoid.JumpPower which is the easiest method and most effective. We can make the player jump higher than normal by doing

Humanoid.JumpPower = 100 --change to whatever you want 50 is the normal jump power

now we have to add an event and check to see if the part is part of a player

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:IsA("Model") then
        print("Is A Player")
    end
end)

next is to find and define the humanoid

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:IsA("Model") then
        Humanoid = hit.Parent:FindFirstChild("Humanoid")
    end
end)

now to fill in the rest. I like to use a debounce so there is no threat of lag

ok = true
script.Parent.Touched:Connect(function(hit)
    if hit.Parent:IsA("Model") and ok == true then
        ok = false
        local Humanoid = hit.Parent:FindFirstChild("Humanoid")
        Humanoid.JumpPower = 100 --Makes the player jump higher
        Humanoid.Jump = true --Makes the player jump
        wait(0.5)
        Humanoid.JumpPower = 50 --Normal Jump
        ok = true
    end
end)
