Wow. You know how you could help? By posting the crash dump(if you know what a crash dump is).

oh, sorry, the problem is here:

i added the pocketmine\math\Vector3 on the file too, but it does not work. please help

You want to know how you could help even more? By posting full code.

Fix pocketmine\maths\Vector3 to pocketmine\math\Vector3.

ok, now the problem is this one, im getting crazy

PHP:

use pocketmine\item\Item;


LOVE YOU, THANKS!
