I put my own thread at a place in the code as follows:
I want this thread to stop when the player logs out. Where is the place where all the player's threads are killed when he logs out, so I put the code to stop it?

And, is this code right to stop this thread?

yes, inside a try-catch block

I don't ask this, I want to know where in the code is the location where all threads close as the player logs out.
