Getting a simple game to restart

in Programming Questions • 3 months ago

I am working on a simple game and trying to get it to restart by either clicking a button (or the mouse). I've looked at many different topics in the forum and tried to get the code to work, but it won't restart. Everything I read previously about making a restart point in setup() makes sense, I just can't get it to work. Here is my code (I have it working without LOSER being displayed, but I'm not sure why it is permanently there now...) Any help would be appreciated!

color bg = color(220,220,220);

float ballsize=40.0;

float speed = 1;

float yball = random(ballsize,(height-ballsize));

float xball = random(ballsize,(width-ballsize));

float ball_xdirection=1;

float ball_ydirection=1;

float textspeed = 0.01;

boolean lost = false;

int points = 0;

int opacity = 250;

PFont font1;

PFont font2;

PFont font3;

PFont font4;

void setup(){

size(300,300);

font1 = loadFont("BradleyHandITCTT-Bold-48.vlw");

font2 = loadFont("Garamond-14.vlw");

font3 = loadFont("Stencil-14.vlw");

font4 = loadFont("StarJedi-14.vlw");

reset();

}

void draw(){

smooth();

fill(214,22,44);

background(bg);

strokeWeight(1);

ellipse(xball,yball,ballsize,ballsize);

xball=xball+((.5*speed)*ball_xdirection);

yball=yball+(speed*ball_ydirection);

textFont(font3);

textAlign(CENTER);

textLeading(30);

fill(0,opacity);

String s = " BOUNCING BALLS! Use your mouse to keep the ball from touching the bottom. You get a point each time you save the ball, but be careful it gets faster!";

text(s,width/2,height/2,200,200);

opacity +=-1.2*textspeed;

fill(106,8,160);

rectMode(CENTER);

rect(mouseX,280,50,15);

if(yball == 252 && xball <= mouseX+27 && xball >= mouseX-27){

speed *=1.1;

ball_ydirection *= -1;

points = points+1;

println(+points+" points for you");

}

if (xball > width-(ballsize/2) || xball<(ballsize/2)){

ball_xdirection*=-1;

}

if(yball<(ballsize/2)) {

ball_ydirection *=-1;

}

if(yball>height-(ballsize/2)){

textFont(font1);

textAlign(CENTER);

text("GAME OVER!", width/2,height/2);

textFont(font2);

textAlign(RIGHT);

fill(0);

text("Points:"+points,width-20,20);

noLoop();

lost = true;

}

if(points <= 5){

fill(69,17,245);

textFont(font1);

text("Loser!", width/2, height/3);

}

if(points >= 20){

fill(244,245,17);

textFont(font4);

text("You're a Master!",200, height/3);

}

void keyPressed(){

reset();

}

void reset(){

smooth();

fill(214,22,44);

background(bg);

strokeWeight(1);

ellipse(xball,yball,ballsize,ballsize);

xball=xball+((.5*speed)*ball_xdirection);

yball=yball+(speed*ball_ydirection);

You don't reset opacity, points, lost and several other variables...

Re: Getting a simple game to restart

Even when I put all of my variables into reset() it doesn't reset when I press any key. I'm not sure what I am missing.

I am not sure. Can you show the updated sketch?
General minor advice (stylistic): you can put the message you display (s) as a global variable with a better (longer) name (or as a constant in the text() call).

Here is the updated sketch. I'm sorry, I'm not sure what a global variable is. I have only been working with Processing for a month or so in an education graduate class on cognition. I get the idea behind the reset() idea, but I can't get it to work. Thank you so much for your help!

Re: Getting a simple game to restart

In this version, the reset() method declares a bunch of new variables that are never used. Instead, you want to simply set the values. Also, you need to restart the loop after calling noLoop() with the "Game Over" message. I think I only changed the reset method as follows, and got it to work:

void reset() {
bg = color(220, 220, 220);
ballsize=40.0;
speed = 1;
yball = random(ballsize, (height/2-ballsize));
xball = random(ballsize, (width/2-ballsize));
ball_xdirection=1;
ball_ydirection=1;
textspeed = 0.01;
lost = false;
points = 0;
opacity = 250;
loop();
}

Re: Re: Getting a simple game to restart

That makes perfect sense! Thank you so much for your help. The only issue I'm seeing now is that the ball passes through my "block" without bouncing off! The reset works perfectly, but I'm not sure why the game itself was affected.

color bg = color(220,220,220);

float ballsize=40.0;

float speed = 1;

float yball = random(ballsize,(height-ballsize));

float xball = random(ballsize,(width-ballsize));

float ball_ydirection=1;

My changes had no impact on that behavior. It was doing that when I started, but I didn't look at your earlier code to see what might have changed.

Re: Re: Getting a simple game to restart

Ok. The first time the program runs everything works fine. When you lose and click to restart, then the ball passes through the block. Ideas? I've tried changing a couple of the reset variables with no luck.

color bg = color(220,220,220);

float ballsize=40.0;

float speed = 1;

float yball = random(ballsize,(height-ballsize));

float xball = random(ballsize,(width-ballsize));

float ball_xdirection=1;

float ball_ydirection=1;

float textspeed = 0.01;

int points = 0;

int opacity = 250;

boolean lost = false;

PFont font1;

PFont font2;

PFont font3;

PFont font4;

void setup(){

size(300,300);

font1 = loadFont("BradleyHandITCTT-Bold-48.vlw");

font2 = loadFont("Garamond-14.vlw");

font3 = loadFont("HoboStd-14.vlw");

font4 = loadFont("LithosPro-Regular-20.vlw");

}

void draw(){

smooth();

fill(214,22,44);

background(bg);

strokeWeight(1);

ellipse(xball,yball,ballsize,ballsize);

xball=xball+((.5*speed)*ball_xdirection);

yball=yball+(speed*ball_ydirection);

textFont(font3);

textAlign(CENTER);

textLeading(30);

fill(0,opacity);

String s = " BOUNCING BALLS! Use your mouse to keep the ball from touching the bottom. You get a point each time you save the ball, but be careful it gets faster!";

text(s,width/2,height/2,200,200);

opacity +=-1.2*textspeed;

fill(106,8,160);

rectMode(CENTER);

rect(mouseX,280,50,15);

if(yball == 252 && xball <= mouseX+27 && xball >= mouseX-27){

speed *=1.1;

ball_ydirection *= -1;

points = points+1;

println(+points+" points for you");

}

if (xball > width-(ballsize/2) || xball<(ballsize/2)){

ball_xdirection*=-1;

}

if(yball<(ballsize/2)) {

ball_ydirection *=-1;

}

if(yball>height-(ballsize/2)){

textFont(font1);

That's strange... it was working earlier. I'll have to take a look at it. Thank you again for all your help!

Re: Getting a simple game to restart

I commented out the fonts as I don't have them.

You made a too strict check: yball == 252
yball being computed from a float, it might not happen. Better test with an inequality.
I changed that and some other little things. Compare with your code.
Notice that I don't set the global variables, I just call reset() in setup().

// final means: won't change, no need to reset
final color bg = color(220, 220, 220);
final float textspeed = 0.01;
final float ballsize = 40.0;
final int paddleY = 280;
final int paddleH = 15;
final int paddleW = 50;
float speed;
float yball;
float xball;
float ball_xdirection;
float ball_ydirection;
int points;
int opacity;
boolean lost;
PFont font1;
PFont font2;
PFont font3;
PFont font4;
void setup() {
size(300, 300);
/*
font1 = loadFont("BradleyHandITCTT-Bold-48.vlw");
font2 = loadFont("Garamond-14.vlw");
font3 = loadFont("HoboStd-14.vlw");
font4 = loadFont("LithosPro-Regular-20.vlw");
*/
reset();
}
void draw() {
smooth();
fill(214, 22, 44);
background(bg);
strokeWeight(1);
ellipse(xball, yball, ballsize, ballsize);
xball=xball+((.5*speed)*ball_xdirection);
yball=yball+(speed*ball_ydirection);
//f textFont(font3);
textAlign(CENTER);
textLeading(30);
fill(0, opacity);
String s = " BOUNCING BALLS! Use your mouse to keep the ball from touching the bottom. You get a point each time you save the ball, but be careful it gets faster!";
text(s, width/2, height/2, 200, 200);
opacity +=-1.2*textspeed;
fill(106, 8, 160);
rectMode(CENTER);
rect(mouseX, paddleY, paddleW, paddleH);
if (yball > paddleY - ballsize/2 - paddleH/2 &&
xball >= mouseX - paddleW / 2 && xball <= mouseX + paddleW / 2) {
speed *=1.1;
ball_ydirection *= -1;
points = points+1;
println(+points+" points for you");
}
if (xball > width-(ballsize/2) || xball<(ballsize/2)) {
ball_xdirection*=-1;
}
if (yball<(ballsize/2)) {
ball_ydirection *=-1;
}
if (yball > height-(ballsize/2)) {
// textFont(font1);
textAlign(CENTER);
text("GAME OVER!", width/2, height/2);
// textFont(font3);
text("Press any key to restart", width/2, height/2+20);
// textFont(font2);
textAlign(RIGHT);
fill(0);
text("Points:"+points, width-20, 20);
noLoop();
lost = true;
if (points <= 5) {
fill(69, 17, 245);
// textFont(font1);
text("Loser!", width/2, height/3);
}
if (points >= 20) {
fill(244, 245, 17);
// textFont(font4);
text("You're a Master!", 200, height/3);
}
}
}
void keyPressed() {
reset();
loop();
}
void reset() {
speed = 1;
yball = random(ballsize, (height/2-ballsize));
xball = random(ballsize, (width/2-ballsize));
ball_xdirection = 1;
ball_ydirection = 1;
lost = false;
points = 0;
opacity = 250;
}

There is still a little bug I let to avoid changing too much your code.
But you better do:

if (yball > paddleY - ballsize/2 - paddleH/2) {
if (xball >= mouseX - paddleW / 2 && xball <= mouseX + paddleW / 2) {
// Handle rebound
} else {
// Handle end of game
}
}
