Assuming you want to make the double jump happen when you double tap space, I would first enable flying for the player when they join. Then, place a PLAYER EVENT: Start Fly block. Right after that, place a GAME ACTION: Cancel Event. Then, you can use PLAYER ACTION: Launch Up or something similar to make the player get launched up whenever they trigger this.
