Where to start: creating a high score board

in General Discussion • Other • 5 months ago

This is something that I really want to do but I have absolutely no idea where to start!

At the end of each cycle in the game, the user's score is displayed. I would like the sketch to remember the 5 lowest scores (the aim is to achieve the lowest score possible) and display them on a leaderboard.

I would like to be able to have three initials next to the top 5 highest scores.

for example the scoreboard would look like this

AMP - 343
LVW - 356
MPG - 359
MPG - 406
SJW - 410

Then if the next player scored 360, the game would prompt them to enter three initials, eg- AHM

the scoreboard would update to

AMP - 343
LVW - 356
MPG - 359
AHM - 360
MPG - 406

but if a player scored 500, it would not prompt for an initial and the scoreboard would remain as is.

furthermore, any way to write the results to a save file which would recall the data when the sketch was closed and reopened.

Any suggestions of where to even start would be greatly welcome! Thanks in advance!!

Start with an array that holds 5 ints. Write a method to add (or not) an incoming new score at the correct place and shift the current scores a place when needed. You'll come a long way with things like: array, for loop, if statement.

Code Example

int[] scores = new int[5];
int score;
void setup() {
size(400, 400);
textSize(30);
for (int i=0; i<scores.length; i++) {
scores[i] = 1000;
}
}
void draw() {
background(0);
text("Scores: ", 50, 60);
for (int i=0; i<scores.length; i++) {
text(scores[i], 50, 120+60*i);
}
text("Last try: ", 220, 60);
text(score, 220, 120);
}
void keyPressed() {
score = int(random(1000));
addNewScore(score);
}
void addNewScore(int score) {
for (int i=0; i<scores.length; i++) {
if (score<=scores[i]) {
for (int j=scores.length-1; j>=max(i,1); j--) {
scores[j] = scores[j-1];
}
scores[i] = score;
break;
}
}
}

Wow! Thanks you so much!

I've been able to implement this into my game and it now displays the last high score! I can't work out how to get this to update into the 5 top scores though :/ They start at 999 and after running through the game, they all change to 0. So when I start the sketch it looks like this:

and then after running through the sketch it looks like this:

(Don't worry about the missing dinosaur, that is still there and works fine)

So I'm guessing somewhere it is updating the array to 0 as it runs through the different modes of the sketch and because the actual score is greater than 0, it isn't updating the array. I've got no idea where this 0 is though! :(

Any suggestions?

UPDATE:

I've now got it so that the last score updates the best scores IF thew best score is higher than the last. Winner!!

Down side, it updates all of the scores to the new quickest

Here's the code I'm using:

int mode=0;
int upAccumTime;
int upStartTime;
boolean upRunning = false;
int upDisplayTime;
PFont score_font;
OpenScreen oScr;
ReadyScreen rScr;
SteadyScreen sScr;
GoScreen gScr;
FinishScreen fScr;
int downStartTime;
import ddf.minim.*;
PImage musicOn;
PImage musicOff;
PImage soundOn;
PImage soundOff;
Minim minim;
AudioPlayer player;
AudioPlayer player2;
boolean musicOn_Off=false;
boolean soundOn_Off=false;
int[] scores = new int[5];
int score;
void setup() {
size(600, 600);
smooth();
musicOn=loadImage("music_play.jpg");
musicOff=loadImage("music_mute.jpg");
soundOn=loadImage("sound_play.jpg");
soundOff=loadImage("sound_mute.jpg");
minim = new Minim(this);
player = minim.loadFile("by_the_way.mp3");
player2 = minim.loadFile("dino_sound.mp3");
for (int i=0; i<scores.length; i++){scores[i] = 9999;}
}
void draw() {
smooth();
oScr= new OpenScreen();
rScr= new ReadyScreen();
sScr= new SteadyScreen();
gScr= new GoScreen();
fScr= new FinishScreen();
score_font=loadFont("scoreFont.vlw");
int thisTime = millis();
int dDecimal;
float downTimerTime=random(750,10000);
if (mode ==0)
{oScr.run(); upAccumTime=0; upDisplayTime=score;
fill(255);textFont(score_font,20);text("Best Score: ", width/4, height/3);text("Last Score: ", width-width/4, height/3, 60);
for(int i=0;i<scores.length; i++){textFont(score_font,16);text(scores[i], width/4, height/2.4+20*i);}
text(score, width-width/4, height/2.5);
}
else if (mode==1)
{rScr.run();downStartTime=millis();}
else if (mode==2)
{sScr.run(); if(millis()>downStartTime+downTimerTime){mode=3;}}
else if (mode==3)
{gScr.run(); if(upRunning==false) {upStartTime=millis(); upRunning=true;}}
else if (mode==4)
{fScr.run(); if (upRunning == true) {upRunning=false; upAccumTime=upAccumTime+millis()-upStartTime;}}
if (upRunning == true) {upDisplayTime = upAccumTime + millis() - upStartTime;}
dDecimal=(upDisplayTime);
score=dDecimal;
if (mode==4){fill(0); textFont(score_font, 100); text(nf(dDecimal,2),width/2, height/2 + 40);score=dDecimal;addNewScore(score);}
musicOn_Off();
soundOn_Off();
}
void mousePressed(){
if (mode==1) {mode=2;}
//else if (mode==2) {mode=3;}
else if (mode==3) {mode=4;}
if(mouseX>width/12&&mouseY>height-height/8&&mouseX<width/12+50&&mouseY<height+50-height/8){ musicOn_Off=!musicOn_Off;}
if(mouseX>width-width/12&&mouseY>height-height/8&&mouseX<width+50-width/12&&mouseY<height+50-height/8){soundOn_Off=!soundOn_Off;}
}
void keyPressed(){
if (mode==0) {mode=1;}
else if (mode==4) {mode=0;}
}
void musicOn_Off(){
if(musicOn_Off==true){image(musicOn,width/12,height-height/8);player.play();}
else{image(musicOff,width/12,height-height/8);player.pause();}
}
void soundOn_Off(){
if(soundOn_Off==true){image(soundOn,width-width/12,height-height/8); if(mode==0){player2.play();}}
else{image(soundOff,width-width/12,height-height/8);player2.pause();}
}
void addNewScore(int score) {
for (int i=0; i<scores.length; i++) {
if (score<=scores[i]) {
for (int j=scores.length-1; j>=max(i,1); j--) {
scores[j] = scores[j-1];
}
scores[i] = score;
break;
}
}
}

Cheers again
