Jumping

Jumping is a feature introduced in Grand Theft Auto III and had been used in all the other GTA games furtherwards except GTA: Chinatown Wars (instead of jumping, a rolling command is used and presumably the jump command). In order to jump, on a Playstation, Square must be pressed, Xbox, X must be pressed and on PC, Spacebar is usually used as it's the default key. In GTA: San Andreas, GTA IV, The Lost and Damned and The Ballad of Gay Tony, climbing was inroduced so when the jump button is pressed near a low (but not too low), medium sized, reachable or vaultable object, the player will climb onto or over the object. Jumping is usually used to jump over a gap that can't really be gone over if without jumping. Only on GTA: San Andreas is where when in water can jumping be performed when not near and object. In other GTA games which allow swimming, the jumping command can only be used when near a climbable object. In GTA: Chinatown Wars, a rolling command is used, even though it's not actually a jump that's performed, objects can be vaulted over so it acts similar to the jumping command.
