==============
**Hérite de :** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
Un émetteur de particules 2D basé sur le CPU.
.. rst-class:: classref-introduction-group
Description
-----------
Nœud de particules 2D calculées par le CPU pour créer une variété de systèmes et d'effets de particules.
Voir aussi :ref:`GPUParticles2D<class_GPUParticles2D>`, qui fournit la même fonctionnalité en utilisant l'accélération matérielle, mais peut ne pas fonctionner sur des appareils plus anciens.

.. rst-class:: classref-method
|void| **request_particles_process**\ (\ process_time\: :ref:`float<class_float>`\ ) :ref:`🔗<class_CPUParticles2D_method_request_particles_process>`
Demande aux particules de traiter pour un temps de processus supplémentaire pendant une seule trame.
Utile pour la lecture de particules, si utilisé en combinaison avec :ref:`use_fixed_seed<class_CPUParticles2D_property_use_fixed_seed>` ou en appelant :ref:`restart()<class_CPUParticles2D_method_restart>` avec le paramètre ``keep_seed`` défini à ``true``.

.. rst-class:: classref-method
|void| **restart**\ (\ keep_seed\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_CPUParticles2D_method_restart>`
Redémarre l'émetteur de particules.
Si ``keep_seed`` vaut ``true``, la graine aléatoire actuelle sera conservée. Utile pour l'avancement et la lecture.
