[SOLVED] How do i force the player to jump?

I am making this script that should launch the player forward using a BodyVelocity and i want the player to jump because otherwise the velocity would decrease allot than if the player were to actually jump.

This is my current script:

local player = game.Players.LocalPlayer
local char = player.Character
local rootpart = char.HumanoidRootPart
char.Humanoid.Jump = true
local force = Instance.new("BodyVelocity",rootpart)
force.Velocity = rootpart.CFrame.lookVector * Vector3.new(50,0,50)

But the problem is that the char.Humanoid.Jump = true doesn't make the character jump. So what i am asking is Can i force the player to jump? Is that even possible?

If this is not possible, please let me know if there is a way to force the player to jump.
