I need help with a code (timer)

Processing Coding Questions
21

Does it do what you want?

22

with full screen you don’t see the console anyway

do you mean println(result);

23

How to do this

This
randomWait= random(4000, 10000);
won’t work.

you need this command where you start a new rect otherwise the value is random once and keeps the value forever. Bad.

same here:

int timer2=millis();
int result= millis()-timer2;

you need to have

int timer2;
int result;

before setup()

BUT

say

timer2=millis(); // start measurement

and

result = millis()-timer2;     // stop measurement  
println(result);

in the correct places in your code where you want to start and stop (measure) the timer!!!

i need the result in console because after the program i need copy the times

25

yes, follow my ideas above

I just finished here your Sketch

by the way: say frameRate(1900); or so, because a very low frameRate like 30 would destroy the measurements

26

don’t know probably we measure how fast your keyboard is also… :wink:

I have this but in console when i click a button put a all the values 0

int cuadrado=20;
float recX, recY;
float randomWait= random(2000,6000);
int timer;
int timer2;
int result;
boolean showingRect=true;
String timeString = “”;

void setup() {
fullScreen();
noCursor();
fill(250);
frameRate(1900);
recX = random (width-cuadrado);
recY = random (height-cuadrado);
background(0);
timer2= millis();
result= millis()-timer2;
}

void draw() {
background(0);

// Eval flag showingRect
if (showingRect) {
// show rect
rect(recX, recY, cuadrado, cuadrado);
} else {
// pausing, wait for timer
text(timeString, 100, 122);
if (millis() - timer > randomWait) {
// NEW RECT
showingRect=true;
recX = random (width-cuadrado);
recY = random (height-cuadrado);
}
}
}

void keyPressed () {
// pause the rect
timer=millis();
showingRect=false;
println(result);
}

please make sure you start the measurement in the correct place in your code.

When does the measurement begin?

and end it in the right section of your code.

Hint: setup() is not the right place and having one directly after the other won’t work either.

As I tried to explain:

hi chrissir i cant reply this days but i think im finished is this correct?

int cuadrado=20;
float recX, recY;
float randomWait= random(2000,6000);
int timer;
int timer2;
int result;
boolean showingRect=true;
String timeString = “”;

void setup() {
fullScreen();
noCursor();
fill(250);
frameRate(1900);
recX = random (width-cuadrado);
recY = random (height-cuadrado);
background(0);
}

void draw() {
background(0);

// Eval flag showingRect
if (showingRect) {
// show rect
rect(recX, recY, cuadrado, cuadrado);
} else {
// pausing, wait for timer
text(timeString, 100, 122);
if (millis() - timer > randomWait) {
// NEW RECT
showingRect=true;
recX = random (width-cuadrado);
recY = random (height-cuadrado);
timer2=millis();
}
}
}

void keyPressed () {
// pause the rect
timer=millis();
result=millis()-timer2;
showingRect=false;
println(result);

31

I think that’s correct!!

Did you test it?

32

This you must have where you start a new rect

33

Yes and is perfect for my project

34

I will try it

Thanks for your feedback.

This: randomWait= random(2000,6000); is important so that the time between appearances of rect is always different

37

i do it and of course is perfect
