Hi, what should I keep in mind when updating a plugin from 3.x to 4.0.0? Yesterday I changed the api of some plugins that were made for 3.x for 4.0.0, but I got different errors, what can I do, I hardly know about php
You can either ask the original authors to update it or simply learn php. Other than that, there is nothing that you can do.
Hey, You could look at the API 4 change logs and see what has changed https://github.com/pmmp/PocketMine-MP/blob/4.0.3/changelogs/4.0.md#403
