The OnDragDrop method is a virtual method in the Editor.SceneViewportWidget class. It is designed to handle drag-and-drop events within the scene viewport widget. This method is called when a drag-and-drop operation is completed, allowing you to define custom behavior for handling the dropped data.
To use the OnDragDrop method, you should override it in a subclass of SceneViewportWidget. Implement your custom logic to handle the drag-and-drop event, such as processing the data being dropped or updating the UI accordingly.
Ensure that the ev parameter, which is of type Editor.Widget/DragEvent, is properly utilized to access information about the drag event, such as the data being dragged and the source of the drag operation.
public class CustomSceneViewportWidget : Editor.SceneViewportWidget
{
public override void OnDragDrop(Editor.Widget.DragEvent ev)
{
// Custom logic to handle the drag-and-drop event
if (ev.Data is MyCustomDataType data)
{
// Process the dropped data
HandleDroppedData(data);
}
}
private void HandleDroppedData(MyCustomDataType data)
{
// Implement your logic to handle the data
}
}
