I’m creating a game in processing and I’m having issues with my GUI using ControlP5. My current setup is that there is a startwindow ControlP5, a tankswindow ControlP5, a howtoplaywindow ControlP5, etc. My issue is that when I click certain buttons the window is supposed to switch, but the sketch is skipping those windows and going directly to another one. This occurs specifically when, in the tankswindow, you select “Restart.” This is supposed to take you back the startwindow, which has an option to create another tankswindow, however the sketch goes directly to a new tankswindow. This also occurs when someone wins the game. After this occurs, a winnerwindow is supposed to be displayed, which has an option to “Play Again” or “Exit.” If the user selects “Play Again,” the sketch should go back to the startwindow, which has an option to go back to the tankswindow. Again, the sketch skips both the winnerwindow (only sometimes though) and the startwindow, going directly to the tankswindow.
The game is Tanks, and the rules are just to click and drag your mouse to launch projectiles at your enemy tank. Here is my code:
TanksWindow (where the sketch is drawn):
import processing.sound.*;

ControlP5 startwindow, tankswindow, howtoplaywindow, htptankswindow, winnerwindow; //Different windows with different buttons, labels, and textareas

SoundFile shoot, explosion, tankExplosion;
boolean turn; // Determines which tank's turn it is; true is left, false is right
Button start, howtoplay, htpstart, restart, htptanks, resume, playagain, exit;
Textlabel tankslabel, TWtankslabel, howtoplaylabel, congratslabel, htptankslabel, menulabel, twhowtoplaylabel;
Textarea instructions, twinstructions;
PImage heart; // For lives
float wind; //X accelleration representing wind
boolean paused; //determines if functionality is paused after a button press (to avoid bad actions)
int pauseframe;//determines when first paused
String pausebefore;
void setup(){

What I’ve tried so far is “return”-ing after every action in my draw method to stop the sketch from performing two actions in one frame, and creating a “pause” as a buffer between an action happening and allowing any other action to occur. Neither of these fixed the problem
Any help would be really appreciated! This is my GitHub repo in case anyone wants to try running the game.Thank you so much!
