An IntegerField lets users input a numerical integer value. It accepts and displays text input. You can set placeholder text to provide hints or instructions to the user on what to enter. You can also add validation functions to ensure that the entered data meets certain requirements.
참고
To align an IntegerField with other fields in an Inspector window, simply apply the USS class to it. For more information, refer to .
.unity-base-field__alignedBaseFieldCreate an IntegerField
You can create an IntegerField with UI Builder, UXML, and C#. The following C# code creates an IntegerField:
var integerField = new IntegerField("Label text");
Set a placeholder text
You can set a placeholder text for the element. You can also hide the placeholder text on focus.
참고
The placeholder text won't display if you set a value for the element. To unset a value in UI Builder, right-click the Value field in the element's Inspector tab and select Unset.
myElement.textEdition.placeholder = "Enter your value here";myElement.textEdition.hidePlaceholderOnFocus = true;
To style the placeholder text, use the USS selector.
.unity-base-text-field__input--placeholderCustomize the input text selection
Input text is selectable by default. You can customize the selection behaviors such as and .
selectAllOnMouseUPselectAllOnFocusIn C#, set them through :
textSelectionmyElement.textSelection.selectAllOnMouseUp = false;myElement.textSelection.selectAllOnFocus = false;
Example
The following UXML example creates an IntegerField:
<UXML xmlns="UnityEngine.UIElements" xmlns:uie="UnityEditor.UIElements"> <IntegerField label="UXML Field" name="the-uxml-field" /></UXML>
The following USS example styles the IntegerField:
.some-styled-field { -unity-font-style: bold;}.some-styled-field .unity-base-field__input { -unity-font-style: italic;}
The following C# example illustrates some of the customizable functionalities of the IntegerField:
// Get a reference to the field from UXML and assign a value to it. var uxmlField = container.Q<IntegerField>("the-uxml-field"); uxmlField.value = 42; // Create a new field, disable it, and give it a style class. var csharpField = new IntegerField("C# Field"); csharpField.SetEnabled(false); csharpField.AddToClassList("some-styled-field"); csharpField.value = uxmlField.value; container.Add(csharpField); // Mirror the value of the UXML field into the C# field. uxmlField.RegisterCallback<ChangeEvent<int>>((evt) => { csharpField.value = evt.newValue; });

TextValueField_1Inherited UXML attributes
This element inherits the following attributes from its base class:
Name | Type | Description |

| | Determines if the touch screen keyboard auto correction is turned on or off. |
| | Path of the target property to be bound. |
| | Specifies the order in which the system should look for Emoji characters when rendering text. If this setting is enabled, the global Emoji Fallback list will be searched first for characters defined as Emoji in the Unicode 14.0 standard. |
| | Whether an element can potentially receive focus. If false, the element can't receive focus. If true, the element receives focus only when its |
| | Hides or shows the mobile input field. |
| | Hides the placeholder on focus. |
| | If set to true, the value property isn't updated until either the user presses Enter or the text field loses focus. |
| | The type of mobile keyboard that will be used. |
| | The string representing the label that will appear beside the field. If the string is empty, the label element is removed from the hierarchy. If the string is not empty, the label element is added to the hierarchy. |
| | The character used for masking in a password field. |
| | Maximum number of characters for the field. |
| | Returns true if the field is used to edit a password. |
| | A short hint to help users understand what to enter in the field. |
| | Returns true if the field is read only. |
| | Controls whether the element's content is selected upon receiving focus. |
| | Controls whether the element's content is selected when you mouse up for the first time. |
| | Controls whether triple clicking selects the entire line under the mouse pointer or not. |
| | Controls whether double-clicking selects the word under the mouse pointer. |
| | Indicates whether the field supports expressions that can be evaluated into a value. Expressions are mathematical or logical constructs, such as "1+1" or "5"2", which can be processed to produce a result. When this property is enabled, the field accepts additional characters required for expressions (e.g., '+', '-', '"', '/', etc.), expanding its functionality beyond the typical restrictions of a text field that might otherwise only allow digits. |
