ANSI Escape Code Not Working?
I'm making a recreation of a card playing videogame called Inscryption for my computer science class. I'm using ANSI escape code sequence ("\033[H\033[2J" & flush) to clear the screen in between updating the board state, but for some reason, these ghost characters have appeared that will not clear. They only appear when two specific functions are run in sequence, and appear to be a partially-run result of the first function. They will not clear when the sequence is used, and they're clogging up the board and making the game pretty much unplayable. I cannot find anything in either function that would do this, so after an hour and a half or so of testing, I'm concerned the problem might lie with the escape sequence? This project is due Wednesday, and I linked the code below on a throwaway java sandbox (editable, runnable, viewable). The functions I am referring to are public void printBoard() and public void printUI(boolean instructions), run as printBoard() --> printUI().

Which terminal are you using?
Not all consoles properly support ANSI escape codes
Also you might want to try using the
flush() after printing the escape codesI tried using flush but it didn't have any effect as far as I could tell. I'm running it on CodeHS on their built-in terminal
I didn't have issues with clearing other displays but it is possible that it is a site glitch?

System.out.print("\033[H\033[3J");
System.out.print("\033[H\033[2J");
System.out.flush();
if I find issues with this solution i will update but as of now seems to have fixed the issue completely!!!
oh side not [2J command has to go at the end because it resets cursor to top left
yeah that might be the issue
I think you could also combine them into a single print
