You’re two years too late. Oh well.
Also, that is not too much code, but it’s not exactly understandable.
Consider this snake code I once wrote:
// Useful arrays to decode/use direction.
int[] dx = {1, 0, -1, 0};
int[] dy = {0, 1, 0, -1};
int[] dk = { RIGHT, DOWN, LEFT, UP };
class Snake {
int x, y; // Current head position.
ArrayList<PVector> tail; // Other segments.
int d; // Direction of movement;
boolean isGrowing = false;
Snake() {
d = 0;
tail = new ArrayList();
}
void draw() {
fill(50,200,50);
stroke(150,200,50);
rect(x,y,20,20);
for( int i = 0; i < tail.size(); i++){
rect(tail.get(i).x,tail.get(i).y,20,20);
}
}
void update() {
tail.add( new PVector(x,y,d) );
if( isGrowing ){
isGrowing = false;
} else {
tail.remove(0);
}
x += 20*dx[d];
y += 20*dy[d];
x += width;
y += height;
x %= width;
y %= height;
}
void grow() {
isGrowing = true;
}
void onKeyPressed() {
for( int i = 0; i < dk.length; i++){
if( key == CODED && keyCode == dk[i] ){
d = i;
}
}
}
}
class Food {
int x, y;
Food() {
newPosition();
}
void draw() {
fill(255,0,0);
stroke(200,0,200);
ellipse(x+10,y+10,20,20);
}
boolean wasEaten(int ox, int oy) {
if ( x == ox && y == oy ) {
newPosition();
return true;
}
return false;
}
void newPosition() {
x = 20 * int(random(width/20));
y = 20 * int(random(height/20));
}
}
class Timer {
int time;
int duration;
Timer() {
duration = 100;
reset();
}
void reset() {
time = millis() + duration;
}
boolean alarm() {
if ( millis() > time ) {
time = millis() + duration;
return true;
}
return false;
}
}
// --- Main driving code follows. Notice how simple its logic is to understand!
Snake snake;
Food food;
Timer timer;
void setup() {
size(600, 400);
snake = new Snake();
food = new Food();
timer = new Timer();
}
void draw() {
background(0);
if ( timer.alarm() ) {
snake.update();
if ( food.wasEaten( snake.x, snake.y ) ) {
snake.grow();
}
}
food.draw();
snake.draw();
}
void keyPressed() {
snake.onKeyPressed();
}
