Inventory Hotbar Glitch

I am sure there was thread for a bug fix, but I can't find it. Now, when people use Win 10, you items you are holding may change rapidly. Any link or fix? I searched

You'll find that you don't have this problem in Minet. That's because PHP is much slower than java or C#

I sometimes have this problem on MCPE.

Same. It's because PHP is so slow. MCPE itself uses C++ but PocketMine uses PHP. Therefore, PHP cannot handle things so fast that MCPE itself can handle.

Me too. Sorry for not clarifying it.

So, why PocketMine still using PHP?

Because @shoghicp can't be bothered rewriting everything
Of course, you can always use MiNET or RedstoneLamp.

Don't intend to use MiNET, if you don't know anything about C Sharp. There are several positive factors, but, also several negative factors. As you have listed some of the positive ones above, I will list some of negative factors which are:
No public plugins- so, you must have to learn C# and MiNET, to create your own plugins.
MiNET was never intended for other server, but HyPixelPE.
Less support, whereas on Pocketmine forums, you can find several qualified developers.

As for Redstonelamp, some of the negative factors above, also qualify for it, and the list goes on. Please research before you actually state using them.

Oh, I'm sorry, but I never said there weren't any bugs. Read. Of course everything has bugs and negative factors. Even PocketMine has bugs and negative factors. You just need to stop arguing without points that apply to nearly all software.

Please learn to read.... I never talked about "bugs" [yet]... Look at my points and then write....

PHP is slow, but it isn't so slow that it can't even handle hotbar change requests... It is a PM issue.

Okay fine *表達問題

Weird things like this happen:
See hotbar

Or use nukkit xD

Maybe PocketMine thinks that you have 8-9 slots.

Not that error. mine is the item in hand switches rapidly.

Thats actually true and i reported that bug a while ago. It checks between 1-9 slots xD
