[Saxavlax001]

After some minutes-hours,I found the correct code that makes PureChat plugin work with steadfast2.No errors found and it's working.Please accept that pr,and also polish words removed automatically I don't know why,but anyway, accept that pr, it's useful and it works.

This will never work... is just copy paste from pocketmine

What do you mean?I had tested it before I do the pull request and works fine.

[Saxavlax001]

But anyway no one is going to accept it,so I'll continue having it on my fork.

This will not work.

[Saxavlax001]

Ok say whatever you want,I don't know if pull request is outdated now,but this change works for me.It may not work now only on this pull request.

Also because something is copy paste,that doesn't mean that it won't work.

@Saxavlax001 If you know anything about PHP, you will know that it is not possible for this to work. All you did was move a function call that broadcasts a message outside the scope where the $ev variable was available. This code will not work, i am telling you this now, don't argue it.
