hi, newb question..

is there a way to pause a Processing program indefinitely while it waits for user input? for example if you were doing a questionnaire and in order to get to the next question you need to click an answer.  thanks.

If you use noLoop(), it will only draw once until redraw() or loop() is called.

As long as you define draw() (even if it's empty) mouse events still work.

Or you could put smaller loops inside your main loop which break up the questions. So something like:

Code:

int progress = 0;

void draw(){
     while(progress == 0){
          ask question;
          check for user input;
          if(input_received){
               progress++;
          }
     }
     while(progress == 1){
          ask question;
          check for user input;
          if(input_received){
               progress++;
          }
     }
     while... etc, etc
}


Not sure if that would be any better, but it's a different approach.
