Descrizione
|
|
----------------------
|
|
|
|
Controlla come viene effettuata la fusione tra i frammenti di origine e destinazione quando si utilizza :ref:`RenderingDevice<class_RenderingDevice>`.
|
|
|
|
Per riferimento, ecco come sono implementate le modalità comuni di fusione per gli utenti nel renderer 2D di Godot:
