The OnDragDrop method is a virtual method in the Editor.GameObjectControlWidget class. It is designed to handle drag-and-drop events when a drag operation is completed and the dragged item is dropped onto the widget. This method can be overridden in derived classes to provide custom behavior for handling drag-and-drop operations.
To use the OnDragDrop method, you should create a subclass of GameObjectControlWidget and override this method to implement custom logic for handling drag-and-drop events. The method receives a parameter of type Editor.Widget/DragEvent, which contains information about the drag event, such as the source and target of the drag operation.
Ensure that your implementation properly handles the drag event and updates the state of the widget or the associated game object as necessary.
public class CustomGameObjectControlWidget : Editor.GameObjectControlWidget
{
public override void OnDragDrop(Editor.Widget.DragEvent ev)
{
// Custom logic for handling the drag-and-drop event
if (ev != null)
{
// Example: Log the source and target of the drag event
Log.Info($"Drag source: {ev.Source}, Drag target: {ev.Target}");
// Implement additional logic to handle the drop
// For example, update the game object or widget state
}
}
}
