The OnDragHover method is a virtual method in the Editor.AssetList class. It is designed to handle drag hover events within the asset list. This method is called when a drag operation is hovering over the asset list, allowing for custom behavior to be implemented during this interaction.
To use the OnDragHover method, you should override it in a subclass of Editor.AssetList. This allows you to define specific behavior when a drag event hovers over the asset list. The method takes a single parameter, ev, which is of type Editor.Widget/DragEvent. This parameter provides information about the drag event, such as the position and data being dragged.
public class CustomAssetList : Editor.AssetList
{
public override void OnDragHover(Editor.Widget.DragEvent ev)
{
// Custom behavior when a drag event hovers over the asset list
if (ev != null)
{
// Example: Change the appearance of the asset list to indicate a valid drop target
HighlightDropTarget(ev.Position);
}
}
private void HighlightDropTarget(Vector2 position)
{
// Implement logic to highlight the drop target based on the position
}
}
