How can I restart the program with keypress

Kitty · November 13, 2019, 4:59am

I want the key “Q” to restart the program, but the reset function isn’t working.

kitkat09-crypto/01/blob/master/Game 2

PImage im[] = new PImage[12];
String imFile[] = {"Start Screen.jpg", "Game Over.jpg", "Introduction.jpg", "Heart.png", "Fireball.png", "Fireball1.png", "Fireball2.png", "Win.jpg", "Hell.jpg", "Ice.jpg", "Acid.jpg", "Mystic.jpg"};
long t = 0;

float timer = (millis() + t)/1000;

int rad = 60;
float xpos, ypos;
float xspeed = 2.8;
float yspeed = 2.2;
int xdirection = 1;
int ydirection = 1;
//Scene 1
float aY = 0;
int aX = 15;
float aV = 0;
float aA = 0.02;
 
float bY = 0;
int bX = 15;

Check out the reset function in my code, and the mousepressed function should give you an idea of how to reset your sketch

https://www.openprocessing.org/sketch/783497

kll · November 13, 2019, 5:24am

your basic idea works here:

float ang=0;

void setup() {
  println("click on canvas and press key [s] stop or [q] run");
}

void draw() {
  background(200, 200, 0);
  translate(width/2,height/2);
  rotate(ang);
  ang +=0.01;
  line(10, 10, 20, 20);
}

void keyPressed() {
  if ( key == 's' ) noLoop();  
  if ( key == 'q' ) loop();
}

but sorry, will not check all that code…

also working with noLoop(); at all is a unusual concept.

edit
Apologies, seems my suggestion was already implemented. Thanks for pointing it out @kll

kll · November 13, 2019, 8:20am

pls see his line 540 where this actually is done that way,

i try:

float ang=-PI/2;

void setup() {
  println("click on canvas and press key [s] stop or [q] run or [r] reset");
}

void draw() {
  background(200, 200, 0);
  translate(width/2, height/2);
  rotate(ang+=0.01);
  line(10, 0, 40, 0);
}

void keyPressed() {
  if ( key == 's' ) noLoop(); 
  if ( key == 'q' ) loop();
  if ( key == 'r' ) reset();
}

void reset() {
  println("reset");
  ang = -PI/2;
  loop();
}

and my short form also works that way
so must be an other logic problem ???

@Kitty, you are aware that we are limited to read your code
as you not store the whole project ( 12 pictures ) at github
we can not run it.

Tiemen · November 13, 2019, 8:31am

Inside void reset() you seem to be redeclaring global variables:

// line 560 and upwards:
int rad = 60;
float xpos, ypos;
float xspeed = 2.8;
// ... rest of the code

Instead of redeclaring them, only reinitialise them. Does that solve your issue?

Kitty · November 13, 2019, 1:12pm

My apologizes, I completely forgot that I’d need to do that. I’ll upload them as soon as possible. Maybe in about 3-4 hours. Sorry for delays.

Kitty · November 13, 2019, 1:13pm

I’ll try and change it in a couple hours

Kitty · November 13, 2019, 4:39pm

Images should be on the github now

Kitty · November 13, 2019, 5:30pm

the timer still seems to no work

Tiemen · November 13, 2019, 5:45pm

So the reset function works now, but only the timer doesn’t?

I think it wouldn’t hurt to take another look at your code and clean it. It’s filled with points of improvements which all might influence the expected outcome. Some examples:

Inside void reset() I still see variables getting declared that are already global variables;
Inside void reset() the same variables get appointed new values several times;
These two issues are happening elsewhere in your sketch as well (such as redeclaring float timer even though it’s a global variable).

Here is the updated code, the timer still doesn’t reset.
Another problem is that the win screen when time reaches 30 it doesn’t work anymore.

github.com

kitkat09-crypto/01/blob/master/Game 3

PImage im[] = new PImage[12];
String imFile[] = {"Start Screen.jpg", "Game Over.jpg", "Introduction.jpg", "Heart.png", "Fireball.png", "Fireball1.png", "Fireball2.png", "Win.jpg", "Hell.jpg", "Ice.jpg", "Acid.jpg", "Mystic.jpg"};

long t = 0;

float timer = (millis() + t)/1000;
 
int rad = 60;
float xpos, ypos;
float xspeed = 2.8;
float yspeed = 2.2;
int xdirection = 1;
int ydirection = 1;
//Scene 1
float aY = 0;
int aX = 15;
float aV = 0;
float aA = 0.02;
 
float bY = 0;

paulgoux · November 14, 2019, 8:13am

Have you tried the code i posted?

Waboqueox · November 14, 2019, 8:36am

Well just taking a fast look, the timer can’t reset because in the line 154 (if I’m not mistaken) you had something like:

float timer = (millis() + t)/1000;

That takes the time since the beginning of the program, using this, the timer resets:

   timer += 1/frameRate;  //float timer = (millis() + t)/1000;

Also changed the text just to see time with one digit

   text("Time: " + (0 + (int)timer), 10, 20);

And trying a little bit the game, I’m not totally sure, but when I reached the 34 secs without die, no more obstacles appeared

Kitty · November 14, 2019, 12:30pm

The goal of the game is to survive 30 seconds.
But after 30 seconds the win screen won’t load. So yeah, that’s one of my problems

Kitty · November 14, 2019, 12:31pm

Which lines do I replace with it?

Waboqueox · November 14, 2019, 12:37pm

Okay, I saw the win screen isn’t implemented, but thought the cause of the obstacles stopped was because it was being restarted.

Its the time okay now?

paulgoux · November 14, 2019, 12:51pm

Remove the line from the preset function and move it outside of the function and remove the line which reinitializes it.

Kitty · November 14, 2019, 1:06pm

I’m not sure, I’ll have to test it out at a later time.
It runs fine when changed on your side, correct?
