UXML element MinMaxSlider

The MinMaxSlider element is a slider that lets users select a range of values within a specified minimum and maximum range. You can use it to set a range of values for various parameters, such as volume levels, character stats, or other numerical values in your UI. To use it, define the minimum and maximum values, and then slide the handle to select the range you want.

Create a MinMaxSlider

You can create a MinMaxSlider with UI Builder, UXML, or C#. The following C# example creates a MinMaxSlider with a default value, low limit, and high limit:

var minMaxSlider = new MinMaxSlider();
minMaxSlider.value = new Vector2(0.25f, 0.75f);
minMaxSlider.lowLimit = 0;
minMaxSlider.highLimit = 1;

Note: To align an element with other fields in an Inspector window, simply apply the .unity-base-field__aligned USS class to it. For more information, refer to BaseField.

示例

The following UXML example creates a MinMaxSlider:

[!code-xml[(External/Resources/editor_resources/Assets/Editor Default Resources/UIPackageResources/Snippets/UXML/MinMaxSliderSnippet.uxml)]

The following C# example illustrates some of the customizable functionalities of the MinMaxSlider:

[!code-cs[(Modules/UIElementsSamplesEditor/Snippets/MinMaxSliderSnippet.cs#sample)]

To try this example live in Unity, go to Window > UI Toolkit > Samples.

C# base class and namespace

C# class: MinMaxSlider
Namespace: UnityEngine.UIElements
Base class: BaseField_1

Member UXML attributes

This element has the following member attributes:

名称	类型	描述
high-limit	float	This is the high limit of the slider.
low-limit	float	This is the low limit of the slider.
value	Vector2	This is the value of the slider. This is a Vector2 where the x is the lower bound and the y is the higher bound.

Inherited UXML attributes

This element inherits the following attributes from its base class:

名称	类型	描述
binding-path	string	Path of the target property to be bound.
focusable	boolean	True if the element can be focused.
label	string	The string representing the label that will appear beside the field.
tabindex	int	An integer used to sort focusables in the focus ring. Must be greater than or equal to zero.
value	Vector2	The value associated with the field.

This element also inherits the following attributes from VisualElement:

名称	类型	描述
content-container	string	Child elements are added to it, usually this is the same as the element itself.
data-source	Object	Assigns a data source to this VisualElement which overrides any inherited data source. This data source is inherited by all children.
data-source-path	string	Path from the data source to the value.
name	string	The name of this VisualElement. Use this property to write USS selectors that target a specific element. The standard practice is to give an element a unique name.
picking-mode	UIElements.PickingMode	Determines if this element can be pick during mouseEvents or IPanel.Pick queries.
style	string	Reference to the style object of this element. Contains data computed from USS files or inline styles written to this object in C#.
tooltip	string	Text to display inside an information box after the user hovers the element for a small amount of time. This is only supported in the Editor UI.
usage-hints	UIElements.UsageHints	A combination of hint values that specify high-level intended usage patterns for the VisualElement. This property can only be set when the VisualElement is not yet part of a Panel. Once part of a Panel, this property becomes effectively read-only, and attempts to change it will throw an exception. The specification of proper UsageHints drives the system to make better decisions on how to process or accelerate certain operations based on the anticipated usage pattern. Note that those hints do not affect behavioral or visual results, but only affect the overall performance of the panel and the elements within. It’s advised to always consider specifying the proper UsageHints, but keep in mind that some UsageHints might be internally ignored under certain conditions (e.g. due to hardware limitations on the target platform).
view-data-key	string	Used for view data persistence, such as tree expanded states, scroll position, or zoom level. This key is used to save and load the view data from the view data store. If you don’t set this key, the persistence is disabled for the associated VisualElement. For more information, refer to View data persistence.

You can also use the Matching Selectors section in the Inspector or the UI Toolkit Debugger to see which USS selectors affect the components of the VisualElement at every level of its hierarchy.
