how do I disable this particle when a player clicks to make players disappear

Could you be more descriptive?

 

Is there an error?.. Can you send the code?

 

What's the issue? What exactly is wrong? Is there any errors? What's happening that isn't working? Please ask a question instead of posting some random image.

 

I think I know what he is talking about.
In the lobby, players have cloaks made out of particles, (similar to what Hypixel has), but when he attempts to disable player visibility, he wants it so the player cannot see these particle cloaks.

 

I don't think cloaks make those type of particles though

 

Still; it's incredibly vague. That did clear things up but its still very difficult to help the guy (or girl) with no code lol

From what people above have replied, all I could say is that:
Runs a check for players in the same world and filter out who has players visibility enabled, then only send the particles packets to them, that'd do the trick theoretically.

Please be more descriptive next time: what you are doing, what is supposed to happen, where's the code that you suspect that might be the problem and what have you tried.
