  .. _class_Particles_draw_passes:

- :ref:`int<class_int>` **draw_passes**

  .. _class_Particles_emitting:

- :ref:`bool<class_bool>` **emitting** - If ``true`` particles are being emitted. Default value: ``true``.

  .. _class_Particles_explosiveness:

- :ref:`float<class_float>` **explosiveness** - Time ratio between each emission. If ``0`` particles are emitted continuously. If ``1`` all particles are emitted simultaneously. Default value: ``0``.

  .. _class_Particles_local_coords:

- :ref:`bool<class_bool>` **local_coords** - If ``true`` particles use the parent node's coordinate space. If ``false`` they use global coordinates. Default value: ``true``.

  .. _class_Particles_one_shot:

- :ref:`bool<class_bool>` **one_shot** - If ``true`` only ``amount`` particles will be emitted. Default value: ``false``.

  .. _class_Particles_preprocess:

- :ref:`float<class_float>` **preprocess**

  .. _class_Particles_process_material:

- :ref:`Material<class_material>` **process_material** - :ref:`Material<class_material>` for processing particles. Can be a :ref:`ParticlesMaterial<class_particlesmaterial>` or a :ref:`ShaderMaterial<class_shadermaterial>`.

  .. _class_Particles_randomness:

Numeric Constants
-----------------

- **MAX_DRAW_PASSES** = **4**

Enums
-----

  .. _enum_Particles_DrawOrder:

enum **DrawOrder**

- **DRAW_ORDER_INDEX** = **0** --- Particles are drawn in the order emitted.
- **DRAW_ORDER_LIFETIME** = **1** --- Particles are drawn in order of remaining lifetime.
- **DRAW_ORDER_VIEW_DEPTH** = **2** --- Particles are drawn in order of depth.


Description
-----------

3D particle node used to create a variety of particle systems and effects. ``Particles`` features an emitter that generates some number of particles at a given rate.

Use the ``process_material`` property to add a :ref:`ParticlesMaterial<class_particlesmaterial>` to configure particle appearance and behavior. Alternatively, you can add a :ref:`ShaderMaterial<class_shadermaterial>` which will be applied to all particles.
