Unigine.ParticlesFieldDeflector Class
| Inherits from: | ParticlesField |
This class represents a deflector for particles generated by Particle Systems. Deflector is a surface field that has no visual representation, but physically interacts with particle systems (other objects are not affected) blocking the way for particles and making them bounce off the deflector's surface. Depending on the specified size, it can be either rectangular or square, plus it can be arbitrarily positioned or rotated to cover the necessary area.
Deflectors are one-sided, meaning the particles can freely penetrate them through one side, and interact only with the opposite one, for example, when falling on it from above.
ParticlesFieldDeflector Class
Properties
vec2 Size#
The size of the Particles Field Deflector along the X and Y axes, in units.
float Roughness#
The roughness coefficient of the Particles Field Deflector. This coefficient defines roughness of the deflector surface the particles collide with, and the range of angles at which particles shall bounce from the deflector.
- The minimum value of 0 means the surface is smooth and bouncing particles are scattered in a uniform direction.
- The maximum value of 1 means the surface is uneven and bouncing particles are scattered in different directions.
float Restitution#
The restitution coefficient of the Particles Field Deflector. This coefficient defines the value of the bouncing impulse a particle will receive on a contact with the deflector (how fast a particle shall bounce from the deflector).
- The minimum value of 0 means the particles do not bounce off, but rather slide along deflector surface.
- The maximum value of 1 makes the angle of bouncing equal to the angle at which the particles fall.
