Why did you remove 1.16.5 when it's still supported by MCreator and is also a very widely used versions?

Sorry if I'm asking such a stupid question, but is that only for the "players since" because of "local" or is it also possible on a server

for example if you want to have a list of your inventory for each player or something

Soo uhh, how does the Copy path block work, a wiki or any documentation would do wonders when working with iti!

Hello, I'm not sure if this is a bug or if I'm just too stupid.
In any case, I use the (
MCreator 2022.1) version and I have the problem that no selection is given in the fields (local: file) which unfortunately causes an error every time.
Did I do something wrong?

You cannot get any selection shown in the variables until you add a variable in the right panel of MCreator. Once you add the Local Variable, save the procedure and then look at the Custom Variables and you should see they are there. If you add more than one variable of the same type, once you select the get/set you can click on the down arrow to choose which variable you want to use.

the block write string to file is messed up.checked the code viewer, says that filebw.write . wtf is that? and when I remove it the procedure gets completely ruined and the code viewer does not show anything after doing any change

Hmmm, there isnt a logic operator for the "Get Json Object Property" which limits this plugin in many ways. I tried to make a vanilla styled crafting system but without that feature I couldn't move on.

I don't mean to bother, but when I attempt to use the "Write text in the file and add a new line" I get an error about an unknown symbol for both the written part and the attempt at doing .newLine();

Any suggestions or fixes I can do to manually fix this temporarily if this is a bug, or am I misunderstanding something?

Greetings, I am trying to use it but it gives me this error:, the problem is that it is not referring to the project, the variables are named as local. Can you tell me how I can refer to the project please? I know how to do it manually but I don't want to have to do it manually every time I do a procedure. (Google translator)

Is there a way to delete lines from a file? If not, is there a different way to save persistent data in MCreator?
