Hi community

The COFFEE SDK Documentation explained the content of "Tparticle" of the AllocVariableTag as:

Particle data (position + direction + wing + lifetime + bits)

But what does "wing" and "bits" stand for?

And how can I calculate the velocity?

Wing is the banking vector. You can create a rotation matrix out of direction and wing and the cross product of both vectors. The bits are PARTICLE_VISIBLE and PARTICLE_ALIVE. They inform you about the state of the particle.
