Star Passability Plugin!: TP_StarPassability.js

Hello fellow developers!

As many of you may already know of the star passability problem in the A-tilesheet, having looked around for so long without a definitive solution I finally stumbled across this https://forums.rpgmakerweb.com/index.php?threads/cityshrimps-cover-tiles.96380/
CityShrimp's Cover Tiles
It worked just fine but when I used it on a tile that had shadow on it it still worked but it removed the shadow from the tile.
So I decided to fix it and in the process I recreated it so now it's like a complete new plugin!

I've removed all the parts that I didn't need so that the plugin now just adds star passability to tiles.

It's use is pretty straight forward, just cover the tiles you want to have star passability with region ID and they will become star passable i.e. you will be able to walk under them.

In spite of  being a programmer I am by no way familiar with either Javascript nor RMMV JS library and with no clear references out there it was pretty hard developing this plugin, so please be aware that this plugin might cause bugs, instability, errors in your game or doesn't work at all!

I tested it and it works fine for me, so you can try using for yourself and see if it works for you.

This piece of code is free for commercial and non-commercial use!

No credit needed!

This plugin is based on CityShrimp's Cover Tiles plugin, link in the description above, so credit goes to CityShrimp.

If you're going to comment, ask a question, request a fix for the plugin I apologize in advance for by 99% most probably I'm not going to answer.

If updates in the plugin are made I'm gonna post them here.

Thank you.
