Vectors Not Moving The Player

I was trying to make a simple lunge script to simulate a really long, low jump. When I am on the ground and I press Reload it makes the player barely move forward and is not getting the intended effect, but if I press reload and jump right after I press it, it works as intended. I am getting no errors.

[lua] function Lunge(ply)

  if ply:GetStaminia() > 30 then 

if ply:KeyDown( IN_RELOAD ) && ply:OnGround() then 



    ply:SetVelocity( ply:GetForward() * 200 + Vector( 1, 1, 150 ) ) 

	ply:SetStaminia(ply:GetStaminia()-30)

end
  else return
  end

	
	end
	
 hook.Add("KeyPress", "Lunge", Lunge)

[/lua]

Move the player off the ground by a couple of units, then set the velocity.

How? I thought SetVelocity was the only way to force a player to move.

player:SetPos()?

This topic was brought up recently. IIRC you can SetGroundEntity( NULL ) first, then apply the velocity.

But you must do SetGroundEntity() back to the world right?

I believe it does it automatically.

Yeah, I think that’s how laser dance does it in any case.
