Input.GetKey

Description

Returns true while the user holds down the key identified by name.

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).

GetKey will report the status of the named key. This might be used to confirm a key is used for auto fire. For the list of key identifiers see Input Manager. When dealing with input it is recommended to use Input.GetAxis and Input.GetButton instead since it allows end-users to configure the keys.

iOS, tvOS: Due platform limitations, GetKeyUp event for keyboard events is delayed by about half a second, see UnityView+Keyboard.mm in the generated Xcode project for more information.
