Starting a timer in an if statement?

in Programming Questions • 11 months ago

I'm trying to make a timer to start only if some conditions are met first however no matter what I do the timer seems to just start count from as soon as I hit run. I need this timer to start in this if statement for my game to work, any help would really help (anything involving the timer I've highlighted in red)

// images are 720 by 540
String[] questions = new String[4];
int[] answers = new int[4];
//int[] questions = new int[4];
int numFrames = 6; // The number of frames in the animation
int frame = 0;
int spincount = 0;
int state = 0;
//questions
int q = 0;
// answers
int an = 0;
//timer
int savedTime;
int totalTime = 11;
//randomise wheel start position variable
int wheel1;
int wheel2;
//pixels to test
// middle pixels
int a;
int b;
int c;
PImage[] images1 = new PImage[6];
PImage[] images2 = new PImage[6];
PImage[] images3 = new PImage[6];

Re: Starting a timer in an if statement?

Have you looked at other time implementations around?
You have a savedTime variable, but you don't initialize it. You check the passedTime variable as soon as it is initialized.

I think you should set a boolean variable indicating that the time is started. You then set the savedTime variable to the current time.
The time should be checked on each frame, only if the boolean is true. That's where you verify the passedTime exceeed the totalTime. In this case, you take an action, and reset the timer boolean variable to false.
