[Particles2D] features an emitter that generates some number of particles at a given rate. Use the [code]process_material[/code] property to add a [ParticlesMaterial] to configure particle appearance and behavior. Alternatively, you can add a [ShaderMaterial] which will be applied to all particles. </description> <tutorials> <link>https://docs.godotengine.org/en/latest/tutorials/2d/particle_systems_2d.html</link> </tutorials> <methods> <method name="capture_rect" qualifiers="const"> <return type="Rect2"> </return> <description> Returns a rectangle containing the positions of all existing particles. </description> </method> <method name="restart"> <return type="void"> </return> <description> Restarts all the existing particles. </description> </method> </methods> <members> <member name="amount" type="int" setter="set_amount" getter="get_amount"> Number of particles emitted in one emission cycle. </member> <member name="draw_order" type="int" setter="set_draw_order" getter="get_draw_order" enum="Particles2D.DrawOrder"> Particle draw order. Uses [code]DRAW_ORDER_*[/code] values. Default value: [code]DRAW_ORDER_INDEX[/code]. </member> <member name="emitting" type="bool" setter="set_emitting" getter="is_emitting"> If [code]true[/code], particles are being emitted. Default value: [code]true[/code]. </member> <member name="explosiveness" type="float" setter="set_explosiveness_ratio" getter="get_explosiveness_ratio"> How rapidly particles in an emission cycle are emitted. If greater than [code]0[/code], there will be a gap in emissions before the next cycle begins. Default value: [code]0[/code]. </member> <member name="fixed_fps" type="int" setter="set_fixed_fps" getter="get_fixed_fps"> The particle system's frame rate is fixed to a value. For instance, changing the value to 2 will make the particles render at 2 frames per second. Note this does not slow down the particle system itself. </member> <member name="fract_delta" type="bool" setter="set_fractional_delta" getter="get_fractional_delta"> If [code]true[/code], results in fractional delta calculation which has a smoother particles display effect. Default value: [code]true[/code] </member> <member name="lifetime" type="float" setter="set_lifetime" getter="get_lifetime"> Amount of time each particle will exist. Default value: [code]1[/code]. </member> <member name="local_coords" type="bool" setter="set_use_local_coordinates" getter="get_use_local_coordinates"> If [code]true[/code], particles use the parent node's coordinate space. If [code]false[/code], they use global coordinates. Default value: [code]true[/code]. </member> <member name="normal_map" type="Texture" setter="set_normal_map" getter="get_normal_map"> Normal map to be used for the [code]texture[/code] property. </member> <member name="one_shot" type="bool" setter="set_one_shot" getter="get_one_shot"> If [code]true[/code], only one emission cycle occurs. If set [code]true[/code] during a cycle, emission will stop at the cycle's end. Default value: [code]false[/code]. </member> <member name="preprocess" type="float" setter="set_pre_process_time" getter="get_pre_process_time"> Particle system starts as if it had already run for this many seconds. </member> <member name="process_material" type="Material" setter="set_process_material" getter="get_process_material"> [Material] for processing particles. Can be a [ParticlesMaterial] or a [ShaderMaterial]. </member> <member name="randomness" type="float" setter="set_randomness_ratio" getter="get_randomness_ratio"> Emission lifetime randomness ratio. Default value: [code]0[/code]. </member> <member name="speed_scale" type="float" setter="set_speed_scale" getter="get_speed_scale"> Particle system's running speed scaling ratio. Default value: [code]1[/code]. A value of [code]0[/code] can be used to pause the particles. </member> <member name="texture" type="Texture" setter="set_texture" getter="get_texture"> Particle texture. If [code]null[/code] particles will be squares. </member> <member name="visibility_rect" type="Rect2" setter="set_visibility_rect" getter="get_visibility_rect"> Editor visibility helper. </member> </members> <constants> <constant name="DRAW_ORDER_INDEX" value="0" enum="DrawOrder"> Particles are drawn in the order emitted. </constant> <constant name="DRAW_ORDER_LIFETIME" value="1" enum="DrawOrder"> Particles are drawn in order of remaining lifetime. </constant> </constants> </class>
