A Jump is an Alternative Movement Option defined by the player character pushing off a surface to gain height and move between positions without Teleporting. Jumping allows players to reach ledges, clear gaps, or avoid hazards. Most games tweak Jump height in some way, either by how long the button is held or by chaining extra moves together.
Some Jumps get taller the longer the button is pressed, or must be charged from the ground. The degree of control a player has after Jumping can vary greatly, with some games having Fixed Jump Arcs and others allowing for free midair movement. Jumping is frequently part of Advanced Movement Techniques.
