Particles is a particle system 3D Node that is used to simulate several types of particle effects, such as explosions, rain, snow, fireflies, or other magical-like shinny sparkles. Particles are drawn using impostors, and given their dynamic behavior, the user must provide a visibility AABB (although helpers to create one automatically exist).
- void set_amount ( int amount )
Set total amount of particles in the system.
- int get_amount ( ) const
Return the total amount of particles in the system.
- void set_emitting ( bool enabled )
Set the "emitting" property state. When emitting, the particle system generates new particles at constant rate.
- bool is_emitting ( ) const
Return the "emitting" property state (see set_emitting).
- void set_visibility_aabb ( AABB aabb )
Set the visibility AABB for the particle system, since the default one will not work properly most of the time.
- AABB get_visibility_aabb ( ) const
Return the current visibility AABB.
- void set_emission_half_extents ( Vector3 half_extents )
Set the half extents for the emission box.
- Vector3 get_emission_half_extents ( ) const
Return the half extents for the emission box.
- void set_gravity_normal ( Vector3 normal )
Set the normal vector towards where gravity is pulling (by default, negative Y).
- Vector3 get_gravity_normal ( ) const
Return the normal vector towards where gravity is pulling (by default, negative Y).
Set a specific variable for the particle system (see VAR_* enum).
Return a specific variable for the particle system (see VAR_* enum).
Set the randomness for a specific variable of the particle system. Randomness produces small changes from the default each time a particle is emitted.
Return the randomness for a specific variable of the particle system. Randomness produces small changes from the default each time a particle is emitted.
Set the position of a color phase (0 to 1)
Return the position of a color phase (0 to 1)
Set the color of a color phase.
Return the color of a color phase.
- void set_material ( Material material )
Set the material used to draw particles
- Material get_material ( ) const
Return the material used to draw particles
