How to use ToolTip in Unity

In Unity, ToolTip is a UI element used in the editor, which provides text information displayed when the mouse hovers over an object or control. ToolTip is often used to provide developers with additional information about an object, field, control, or menu item, thereby helping them better understand and use these elements.

ToolTip usually appears in the form of short text. When the user hovers the mouse over an object that can display the ToolTip, it will automatically appear after a period of time to display relevant instructions, guidance or warnings to the user. ToolTip is a common user interface element that helps provide immediate contextual information and reduce user confusion about unfamiliar elements.

In the Unity editor, ToolTip can be used for the following purposes:

1. Fields and Properties: Add attributes to public fields or properties in your script [Tooltip("Your tooltip text here")]to display corresponding prompt information when hovering over the field in the Inspector.

2. Custom Editor: In a custom Inspector panel, you can use EditorGUILayout.LabelFieldor other GUI elements to add ToolTip for specific controls.

3. Menu Items:[MenuItem] On menu items created using attributes, MenuItem("Your Menu/Path", true, 0, "Your Tooltip")add a ToolTip to the menu item using the fourth argument in .

4. Controls: In a customized Editor window, ToolTip can be added to custom controls (such as buttons, text fields, etc.) to help developers understand their functions.

Example:

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    
    
    [Tooltip("This is a tooltip for myInt field.")]
    public int myIntWithTooltip;

    [MenuItem("Custom Menu/Do Something", false, 0)]
    private static void DoSomething()
    {
    
    
        // Menu item action
    }

    [MenuItem("Custom Menu/Do Something", true)]
    private static bool ValidateDoSomething()
    {
    
    
        return true;
    }
}

In short, ToolTip is used in Unity to provide additional information about objects, fields, controls or menu items, helping developers better understand and use these elements, providing context and tips.
