Input.GetButton

Parameters

Returns

bool True when an axis has been pressed and not released.

Description

Returns true while the virtual button identified by buttonName is held down.

Note: This API is part of the legacy Input class, and not recommended for new projects. The documentation is provided here to support legacy projects that use the old Input Manager and Input class. For new projects you should use the newer and Input System Package. (read more).

Think auto fire - this will return true as long as the button is held down. Use this only when implementing events that trigger an action, eg, shooting a weapon. The buttonName argument will normally be one of the names in InputManager such as Jump or Fire1. GetButton will return to false when it is released.

Note: Use GetAxis for input that controls continuous movement.

// Instantiates a projectile every 0.5 seconds,
// if the Fire1 button (default is Ctrl) is pressed.
