How to remove all particles in an event in 1 frame?

[Akfox]

Set the dropdown to "Frame" instead.

thanks,
but I can’t snap to a specific frame.
I need to remove the entire tail from the red dots at different times.

I need the tail to live 10 frames and disappear

Change delete operator to frame and add the frame you want your tail to be deleted!

not all tails should be removed.

only those whose age is 10 frames

I didn’t accurately formulate the title of the topic,
sorry
