Particle effect not playing

Hello, It would better if you give us more information and the steps to reproduce this error, unity version is important.

How do I ask a good Question

When you click in the particle System, there will be an editor in the Inspector. Then, you can go at the first session or Emission, shape and try to see what happen.

The default particle system has an amount of emission, speed that for sure you'll be able to see it. Try typing F to locate your particle in the Scene Editor or Scaling the particle.

But it seems you are not familiar with particle system, so try reading the API-> Particle System API

or look for a tutorial.

We need more information to help you properly.

I hope I helped you. Greetings
