|
|
2D particle emitter.
|
|
</brief_description>
|
|
<description>
|
|
2D particle node used to create a variety of particle systems and effects. [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.

<member name="amount" type="int" setter="set_amount" getter="get_amount" default="8">
|
|
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" default="0">
|
|
Particle draw order. Uses [code]DRAW_ORDER_*[/code] values.
|
|
</member>
|
|
<member name="emitting" type="bool" setter="set_emitting" getter="is_emitting" default="true">
|
|
If [code]true[/code], particles are being emitted.
|
|
</member>
|
|
<member name="explosiveness" type="float" setter="set_explosiveness_ratio" getter="get_explosiveness_ratio" default="0.0">
|
|
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.
|
|
</member>
|
|
<member name="fixed_fps" type="int" setter="set_fixed_fps" getter="get_fixed_fps" default="0">
|
|
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 simulation of the particle system itself.
|
|
</member>
|
|
<member name="fract_delta" type="bool" setter="set_fractional_delta" getter="get_fractional_delta" default="true">
|
|
If [code]true[/code], results in fractional delta calculation which has a smoother particles display effect.
|
|
</member>
|
|
<member name="lifetime" type="float" setter="set_lifetime" getter="get_lifetime" default="1.0">
|
|
Amount of time each particle will exist.
|
|
</member>
|
|
<member name="local_coords" type="bool" setter="set_use_local_coordinates" getter="get_use_local_coordinates" default="true">
|
|
If [code]true[/code], particles use the parent node's coordinate space. If [code]false[/code], they use global coordinates.
|
|
</member>
|
|
<member name="normal_map" type="Texture" setter="set_normal_map" getter="get_normal_map" default="null">
|
|
Normal map to be used for the [member texture] property.

</member>
|
|
<member name="one_shot" type="bool" setter="set_one_shot" getter="get_one_shot" default="false">
|
|
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.
|
|
