GUILayoutTextField

GUILayoutTextField is a Unity GUI control that displays a single line of editable text. It allows users to input and modify text within the game's user interface. This control is part of Unity's immediate mode GUI system, GUILayout, which automatically handles the arrangement of UI elements.

To use GUILayoutTextField, you typically call it within the OnGUI method of a MonoBehaviour script. The function takes several parameters, including a string to display as the current text, an integer for the maximum number of characters allowed, and an optional string for a tooltip. It returns the modified string after the user has interacted with it.

When the user focuses on the text field, a blinking cursor appears, indicating that input is active. The user can then type characters, delete them, and navigate the text using standard keyboard controls. The GUILayout system automatically sizes the text field to accommodate its content or to fit within the available layout space.

Applications for GUILayoutTextField include name input fields, search bars, chat windows, or any scenario where users need to enter small amounts of text. Its simplicity and integration with the GUILayout system make it a common choice for basic text input in Unity projects.
