How to block movement on the Y Particle system?

Question

Unity

There is a Particle sistem which is a child of the player. The player moves, the Particle sistem moves with him. The Particle sistem settings are set to Simulation space - World.
Is there any way to block the movement of the Particle in Y, provided that the player can change the position in Y?

Answer 1

Create a separate script that will move the particles, hang it on the player, do not make the particles children of the player.
Something like this:

public class Particles : MonoBehaviour
{
    [SerializeField] private ParticleSystem _particle;

    private void FixedUpdate()
    {
        MoveParticles();
    }

    private void MoveParticles()
    {
        var position = _particle.transform.position;
        position.x = transform.position.x;
        _particle.transform.position = position;
    }
}

We place the particles in the inspector and that's it. I have a project in 2d, so there is no z-axis, but if you have 3d, then the z-axis also needs to be moved.
