This example demonstrates how to bind with the binding path in a C# script.
This examples create a custom Editor window to change the name of a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary.
You can find the completed files that this example creates in this GitHub repository.
This guide is for developers familiar with the Unity Editor, UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
See in Glossary Toolkit, and C# scripting. Before you start, get familiar with the following:
Create a custom Editor window in C# with a TextField
. Set the binding path to the name property of a GameObject and make an explicit call to the Bind()
method.
Create a project in Unity with any template.`
In your Project windowA window that shows the contents of your Assets
folder (Project tab) More info
See in Glossary, create a folder named bind-with-binding-path
folder to store your file.
In the bind-with-binding-path folder, create a folder named Editor
.
In the Editor folder, create a C# script named SimpleBindingExample.cs
and replace its contents with the following:
using UnityEditor;
using UnityEngine;
using UnityEditor.UIElements;
using UnityEngine.UIElements;
namespace UIToolkitExamples
{
public class SimpleBindingExample : EditorWindow
{
TextField m_ObjectNameBinding;
[MenuItem("Window/UIToolkitExamples/Simple Binding Example")]
public static void ShowDefaultWindow()
{
var wnd = GetWindow<SimpleBindingExample>();
wnd.titleContent = new GUIContent("Simple Binding");
}
public void CreateGUI()
{
m_ObjectNameBinding = new TextField("Object Name Binding");
// Note: the "name" property of a GameObject is "m_Name" in serialization.
m_ObjectNameBinding.bindingPath = "m_Name";
rootVisualElement.Add(m_ObjectNameBinding);
OnSelectionChange();
}
public void OnSelectionChange()
{
GameObject selectedObject = Selection.activeObject as GameObject;
if (selectedObject != null)
{
// Create the SerializedObject from the current selection
SerializedObject so = new SerializedObject(selectedObject);
// Bind it to the root of the hierarchy. It will find the right object to bind to.
rootVisualElement.Bind(so);
// Alternatively you can instead bind it to the TextField itself.
// m_ObjectNameBinding.Bind(so);
}
else
{
// Unbind the object from the actual visual element that was bound.
rootVisualElement.Unbind();
// If you bound the TextField itself, you'd do this instead:
// m_ObjectNameBinding.Unbind();
// Clear the TextField after the binding is removed
m_ObjectNameBinding.value = "";
}
}
}
}
