Pong with the score! You need to create a font and have it in the data folder (in this example I created "Dialog-24.vlw")

float ballx = 150;
float bally = 200;
float speedx = 2.7;
float speedy = 0.3;
float player1x = 570;
float player1y = 200;
float player2x = 30;
float player2y = 200;
boolean p1xbutton = false; // booleans are variables that are either true or false.
boolean p1ybutton = false;
boolean p2xbutton = false;
boolean p2ybutton = false;
PFont font;
int score1 = 0;
int score2 = 0;
void setup(){
size(600, 400);

fill (250);
textFont(font, 24);
background (50);
smooth();

text(score2, 560, 20);
