UnityEngine.GameObject' does not contain a definition for `particleAnimator'

pe.particleAnimator.force.y = CurrentSpeed;

Type UnityEngine.GameObject' does not contain a definition for particleAnimator’ and no extension method particleAnimator' of type UnityEngine.GameObject’ could be found
what to do?

As you can see in the GameObject documentation, there is no particleAnimator property. You can use GetComponent(ParticleAnimator) instead.
