I am working on a game in processing for my university project but I have a problem. when the game patterns change their positions wont reset. if you let the pattern loop you will see what I mean can anyone help me?

code:

```auto
float X, Y, Xc, Yc, Xm, Ym, Xl, Xr, Yt, Yb, Xm2, Ym2;
float H1, H2, H3, H1x, H1y, Ev;

</div>

I mean is the classes dont start at their default position, when it changes from pattern one to pattern two then back to pattern one, pattern one isn’t in its default positions so the bullets can spawn on the player

Your code is hard to read

please try to put your objects into an array of objects

see [https://github.com/Kango/Processing-snippets/wiki/Variables,-Arrays-and-object-oriented-programming](https://github.com/Kango/Processing-snippets/wiki/Variables,-Arrays-and-object-oriented-programming)

then to reset, for loop over the array and call a function reset() in the class. You have to write the function reset() in the class.
