Ocarina of Time is an action-adventure game with role-playing and puzzle elements. The player controls Link from a third-person perspective in a three-dimensional space. Link primarily fights with a sword and shield; he can also use projectile weapons, bombs, and magic spells.[20] The control scheme introduced techniques such as context-sensitive actions and a targeting system called "Z-targeting"[21][2] In combat, Z-targeting allows the player to have Link focus on an enemy or other objects.[22] When using this technique, the camera follows the target and Link constantly faces it. Projectile attacks are automatically directed at the target and do not require manual aiming. Context-sensitive actions allow multiple tasks to be assigned to one button, simplifying the control scheme. The on-screen display shows what will happen when the button is pushed and changes depending on what the character is doing. For example, the same button that causes Link to push a box if he is standing next to it will have him climb on the box if the analog stick is pushed toward it. Much of the game is spent in battle, but some parts require the use of stealth.
