JobParticleSystem Crash

Unity Engine

Using any Particle-related jobsystem interfaces (IJobParticleSystemParallelForBatch, IJobParticleSystemParallelFor) will cause the system to freeze。
for example:

[BurstCompile]
public struct UpdateParticlesJob : IJobParticleSystemParallelForBatch
{
    public void Execute(ParticleSystemJobData particles, int startIndex, int count)
    {       
    }
}

var p = GetComponent<ParticleSystem>();
UpdateParticlesJob job = new UpdateParticlesJob();
job.ScheduleBatch(p, 100);

Where are you calling this from? Particle jobs need to be called from specific Unity callbacks, i.e. OnParticleUpdateJobScheduled().

You can’t just schedule them in update/lateupdate etc.

Whoa, you can do this? Would you be kind enough to send the link to the documentation?

Thank you very much, you are right, I used the wrong method. Everything worked fine after using OnParticleUpdateJobScheduled. However, incorrect usage should not lead to a Unity crash. In fact, this did not happen in 2021.

Thank you for your response. I have found the reason; it was because they were not being called in the correct place.
