I have been trying to get an old code I wrote, a long time ago, to work(its probably a mess). And I was wondering why it gives me the error message “[something] is not a constructor”. I do not expect anyone to read my mess of a code, but I would like to know some examples for what could be the issue, and then I will go through the code myself. When I greytext what it says is not a constructor, something else is suddenly not a constructor. At the time (and now) I didnt know what a constructor was, so I shouldnt have used one in the code at all.
“player2” is the first thing that is not a constructor in the error message.
Here is the code if you want to have a quick look(I copied it to docs and back into processing, it was a long time ago, but the reason I get errors may be because I didnt copy everything) :
