I want my platformer to have the ability to glide. While button is down, gliding starts, when button is not down, he starts falling. Any way i can do this?
You need a glide and fall animation. I would set the animation image point below the animation at the level you want the player to appear to be gliding and above the image for falling.
On Button pressed: Play Glide animation.
On Button Released: Play fall animation.
Image points are useful for special effects on animations.
