A Vector3Field allows you to enter a Vector3 value.
To align a Vector3Field with other fields in an Inspector window, simply apply the .unity-base-field__aligned USS class to it. For more information, refer to BaseField.
You can create a Vector3Field with UI Builder, UXML, and C#. The following C# example creates a Vector3Field with the default value (15.5, 12.5, 14.5):
Vector3Field myElement = new Vector3Field("Label text");
// Set the default value to (15.5, 12.5, 14.5).
myElement.value = new Vector3(15.5f, 12.5f, 14.5f);
The following UXML example creates a Vector3Field with a placeholder:
[!code-xml[(External/Resources/editor_resources/Assets/Editor Default Resources/UIPackageResources/Snippets/UXML/Vector3FieldSnippet.uxml)]
The following C# example illustrates some of the customizable functionalities of the Vector3Field:
[!code-cs[(Modules/UIElementsSamplesEditor/Snippets/Vector3FieldSnippet.cs#sample)]
To try this example live in Unity, go to Window > UI Toolkit > Samples.
C# class: Vector3Field
Namespace: UnityEngine.UIElements
Base class: BaseCompositeField_3
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. |
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. |
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 (ie. tree expanded states, scroll position, zoom level). This is the key used to save/load the view data from the view data store. Not setting this key will disable persistence for this VisualElement. |
