Hi, I got this code about a car game. I am studing processing in uni and I have trouble understanding this code. Could someone explain to me what different aspects of thsi code do and swap inputs like s(), r() etc. so i would understand what they do. Also would be nice if possible to do the yellow part with IF commands.

PVector p=new

PVector(110,110,0);

float v=0;

boolean[] keys=new boolean[3];

void setup(){

size(220, 220);

smooth();

}

void draw()

{

background(0);

s();

r();

}

void keyPressed()

{

b(true);

}

void keyReleased()

{b(false);

}

void b(boolean d)

{

if(key==CODED){

if(keyCode==LEFT)keys[0]=d;

if(keyCode==RIGHT)keys[1]=d;

if(keyCode==SHIFT)keys[2]=d;

}

}

void s(){

p.z+=(keys[0]?-.1:0)+(keys[1]?.1:0);

v+=(keys[2]?.1:0);

p.x=(p.x+width+v*cos(p.z))%width;

p.y=(p.y+height+v*sin(p.z))%height;v*=.99;

}

void r(){

translate(p.x,p.y);

rotate(p.z);

noStroke();

fill(0);

rect(-10,-10,20,20);

stroke(0);

fill(225);

triangle(-8,-8,15,0,-8,8);

}

Thanks!

Hi,

I am learning processing in school and I need to make a car game where:

the cars front and rear end are different.(can be just a triangle)

arrow key left turns the car left

arrow key right turns the car right

Shift key accelerates

the car's front end is always towards the driving direction

there is always the force of friction applied to the car.
