How to move partices along local axis using script?

[FirePro]

Get the particle TM...then use the appropriate row as your axis of movement.

So if you want to move the particle along its z-axis by 10 units, you'd add (particleTM.row3 * 10) to its position.

Hi, I have same task - need move particles along their local Y-axis (500mm). Can you help me? Thank you.

Code:

public void simulationStep()
{    
    for (int i = 0; i < eventParticleCount; i++)
    {
        int sInx = tf.GetSimIndex(i);

        float eventAge = tf.GetEventAge(sInx);

        if (eventAge == 0)
        {
            Matrix3 particleTM = tf.GetTM(sInx);
            //What I need place here for move particles along their local Y-axis (500mm)
            tf.SetTM(sInx, particleTM);
        }        
    }    
}
