you need to call

animate();

in draw()

I am not sure what you intend with xmove.....

The player is painted with the values x,y (line 30) but you don't change them.
Line 30 should be:

rect(xpos,ypos,50,50);

since x,y and xpos,ypos are global, no need to pass them to the function player() anyway.

the function animate() isn't clear to me... do you intend to make the player stop after a time?

You have a lot of variables that mention x and y that I don't see the purpose of. I removed them from the code below (partially to make sense of what was going on) and it should be easier to see what is going on now:

//Pimp Man
boolean displayStartScreen;
int row = 0;
int col = 0;
int x = 175;
int y = 100;
void setup() {
size(800, 800); //size of game
textAlign(CENTER, CENTER); //alignment of timer
displayStartScreen = true;
}
void draw() {
if (displayStartScreen) {
drawStartScreen(); //call Start Screen
}
else {
background(0); // Black background
fill(255);
text("" + millis() / 1000, 35, 20);
fill(255, 140, 5);
rect(450, 650, 50, 50);
line(200, 100, 200, 400);
line(200, 400, 475, 400);
line(475, 400, 475, 650);
stroke(255);
player(x, y);
}
}
void player(int x, int y) {
fill(0, 255, 0);
rect(x, y, 50, 50);
}
void drawStartScreen() { //Start Screen
background(0); //Black Background
textSize(20);
text("*Hurry, timer has already started!*", width/2, 500);
textSize(30);
text("Press Enter/Return to Start", width/2, height/2); //How to Start
textSize(70);
text("PIMP MAN", 400, 200); //Game Title
}
void check() {
if (row > 7 || col > 7 || row < 0 || col < 0 ) {
background(255);
}
}
void keyPressed() {
if (displayStartScreen && key == ENTER || key == RETURN) {
displayStartScreen = false;
}
// This means is displayStartScreen == FALSE AND key == CODED
if (!displayStartScreen && key == CODED) { // keyCode needed for these
if (keyCode == UP) {
y -= 100;
col = col-1;
check();
}
if (keyCode == LEFT) {
x -= 100;
row = row-1;
check();
}
if (keyCode == RIGHT) {
x += 100;
row = row+1;
check();
}
if (keyCode == DOWN) {
y += 100;
col = col+1;
check();
}
}
}

It's alive! You needed to know the difference between key and keyCode. I also tidied it up a bit. Oh, and the timer now waits for you to start the game.

//Pimp Man
boolean displayStartScreen;
boolean locked = false;
int startTime=0;
int xpos = 0;
int ypos = 0;
int xmove = 0;
int ymove = 0;
void setup() {
size(800, 800); //size of game
textAlign(CENTER, CENTER); //alignment of timer
displayStartScreen = true;
}
void draw() {
if ( displayStartScreen ) {
drawStartScreen(); //call Start Screen
}
else {
background(0); // Black background
fill(255);
text( "" + (millis()-startTime) / 1000, 35, 20 );
fill(255, 140, 5);
rect(450, 650, 50, 50);
line(200, 100, 200, 400);
line(200, 400, 475, 400);
line(475, 400, 475, 650);
stroke(255);
animate();
//player(x, y, xpos, ypos);
}
}
void drawStartScreen() { //Start Screen
background(0); //Black Background
textSize(20);
text("Chill out, the timer hasn't started yet!", width/2, 500); // "*Hurry, timer has already started!*"
textSize(30);
text("Press Enter/Return to Start", width/2, height/2); //How to Start
textSize(70);
text("PIMP MAN", 400, 200); //Game Title
}
void check() {
if (xpos > 7 || ypos > 7 || xpos < 0 || ypos < 0 ) {
background(255);
}
}
void keyPressed() {
if ( displayStartScreen ) {
if (key == ENTER || key == RETURN) { //Pushed to Start
displayStartScreen = false;
startTime = millis();
}
}
else {
if ( !locked ) {
if ( key == CODED ) {
if (keyCode == UP) {
ypos--;
ymove=100;
locked = true;
check();
}
if (keyCode == LEFT) {
xpos--;
xmove=100;
locked = true;
check();
}
if (keyCode == RIGHT) {
xpos++;
xmove=-100;
locked = true;
check();
}
if (keyCode == DOWN) {
ypos++;
ymove=-100;
locked = true;
check();
}
}
}
}
}
void animate( ) {
fill(0, 255, 0);
rect(175+(100*xpos)+xmove, 100+(100*ypos)+ymove, 50, 50);
if (xmove != 0) {
if ( xmove < 0 ) {
xmove+=5;
}
else {
xmove-=5;
}
}
if (ymove != 0) {
if ( ymove < 0 ) {
ymove+=5;
}
else {
ymove-=5;
}
}
if ( xmove == 0 && ymove == 0 ) {
locked = false;
}
}

Re: need help with game!

Even though I have some months in this wonderful Processing community,
I still can't get why testing for key = CODED would be necessary!

I'm very successful up till now on ignoring it completely!

Well, here's my take on the callback function keyPressed() :

void keyPressed() {
  final int k = keyCode;    // just to shorten the if blocks  ^_^

  if ( !locked ) {

    if (k == UP || k == 'W') {
      --ypos;
      ymove  = 100;
      locked = true;
    }
    else if (k == DOWN || k == 'S') {
      ++ypos;
      ymove  = -100;
      locked = true;
    }
    else if (k == LEFT || k == 'A') {
      --xpos;
      xmove  = 100;
      locked = true;
    }
    else if (k == RIGHT || k == 'D') {
      ++xpos;
      xmove  = -100;
      locked = true;
    }

    if (locked)  check();
  }

  else if ( displayStartScreen && (k == ENTER || k == RETURN) ) {
    displayStartScreen = false;
    startTime = millis();
  }
}

And even an attempt at keyReleased() as well:

void keyReleased() {
  final int k = keyCode;

  if ( (k == LEFT  || k == 'A')   && xmove < 0 
    || (k == RIGHT || k == 'D')   && xmove > 0 )
    xmove = 0;

  else if ( (k == UP || k == 'W') && ymove < 0 
    || (k == DOWN    || k == 'S') && ymove > 0 )
    ymove = 0;
}
