struct Particle

The Particle structure contains state information about a particle.

struct Particle

Particle            *prevParticle;	A pointer to the previous particle in the system. This is nullptr for the first particle.
Particle            *nextParticle;	A pointer to the next particle in the system. This is nullptr for the last particle.
long                emitTime;	The time remaining before the particle is emitted.
long                lifeTime;	The time remaining (once the particle is emitted) before the particle dies.
float               radius;	The radius of the particle.
ColorRGBA           color;	The color and transparency of the particle.
UnsignedFixed       orientation;	The orientation of the particle as an unsigned 8.24-bit fixed-point angle. The top 8 bits divide the circle into 256 angles of 360/256 degrees.
Point3D             position;	The world-space position of the particle.
Vector3D            velocity;	The world-space velocity of the particle.
