I know that this doesnt help with anything in the development of your plugin, but i am making a skript gui for your plugin, cause i found out there were more items in the plugin that actually didnt have any change to get them via the inbuilt commands. ( it will give the item when clicking on it in the gui )
Well due to no needed use and no real use for them, I have removed most of them, but If you would like to contribute to the new version, contact me, I would love to have you as a contributor.
I am not really a java dev, same with skirpt. Ive mostly stiched this "plugin" together with some examples from other skripts, like the clickable gui part and so.
I know, im taking examples, not copy-pasting them in. Well, rewriting it in a different skript is sort of copy-pasting too, but the thing is, the end result is going to be 200% different.
Well, help with what? I said i dont know anything from java. The only thing i could do is make a skript addon for your plugin to give the items.
