Hi
I have this grid and I have been trying to make a few changes to it.

If any of you guys could help it would be greatly appreciated.

They are simple questions I hope

It is a grid and each box is has an input for one letter.

I need to make this small program be able to do the following.

1. When you press on the box, a box pops up. When you press the ok button with no letter inputed it does nothing.

2. If you do not input a letter in the field there will be no change and all letter must be capital in the boxes.

3. If you drag a box to another box, the input is copied to the box you dragged it to.

4. I want to define a 'class grid' to the two dimensional array of characters.

Thank you to all you guys in advance.

This is greatly appreciated.

Here is my code

import javax.swing.JOptionPane;

String str = "H";

String newStr = "";

int cell1, cell2;

final int CELL_SIZE = 50;

final int NUM_ROW = 10;

final int NUM_COL = 10;

char[][] letters = new char[NUM_ROW][NUM_COL];

int code;

PFont letterFont;

void setup()

{

initLetters(letters);

displayLetters(letters);

size(NUM_ROW * CELL_SIZE, NUM_COL * CELL_SIZE);

letterFont = createFont("Palatino", CELL_SIZE * 0.6);

textFont(letterFont);

textAlign(CENTER, CENTER);





}

void draw () {



background(255);

if (str != null)

{

fill(color(0));

letters[cell1/CELL_SIZE][cell2/CELL_SIZE] = str.charAt(0);

}

drawGrid();



}

void initLetters(char[][] a)

{

for (int i = 0; i < a.length; i++)

{

for (int j = 0; j < a[0].length; j++)

{

a[i][j] = (0);

}

}

}

void displayLetters(char[][] a)

{

for (int i = 0; i < a.length; i++)

{

for (int j = 0; j < a[0].length; j++)

{

print(a[i][j]);

}

}

}

void drawCell(int row, int col, char letter)

{

stroke(0);

noFill();

rect(col * CELL_SIZE, row * CELL_SIZE, CELL_SIZE, CELL_SIZE);

fill(0);

text(letter, col * CELL_SIZE + CELL_SIZE/2, row * CELL_SIZE + CELL_SIZE/2);

}

void drawGrid()

{

for (int i = 0; i < letters.length; i++)

{

for (int j = 0; j < letters[0].length; j++)

{

drawCell(i, j, letters[i][j]);

}

}

}

void mouseClicked()

{

cell1=mouseY;

cell2=mouseX;

noLoop();

newStr = (String)JOptionPane.showInputDialog("Enter a Character");

loop();

str = newStr;

}

Thanks again!

hey i cant seem to get key released working in my code.
what i need to do is when i press 'P' the loading bar pauses and when i press 'P' again it continues.

Also when i press 'space' the loading bar restarts to the start. This works but when you press 'P' first, the space bar just continues the loading bar instead of restating.

One more thing if you can also help try organise this code in the best possible way that would be great.

Here is the code

// Code Requirements

float stTime;

float pause;

float maping;

float percent;

float number;

float time;

int prog;

boolean started = false;

// Setup and Draw

void setup () {

size(500, 300);

background(255);

fill(0);

textSize(24);

}

void draw () {

if (started) {

background(255);

Bar();

Boarder();

Text();

Percent();

}

}

// Components - Extra Features (Part 3)

//

// Restart

void keyReleased () {

if (key == ' ') {

started = true;

stTime = millis() - pause;

}

// Pause

else if (key == 'p') {

started = false;

pause = millis() - stTime;

}

}

// Starting The Progress Bar (Part 2)

void mouseClicked () {

percent=0;

time = random(2000, 8000);

stTime=millis();

started = true;

}

// Main Components And Function

//

// The Progress Bar

void Bar() {

maping = map(percent, 0, 100, 0, 250);

for (prog=0;prog<maping;prog++) {

stroke(255-prog);

line(width/4+prog, 9*height/20, width/4+prog, 11*height/20);

}

}

// Calculating The Percentage

void Percent() {

number = millis() - stTime;

if (int(percent)<=100) {

percent = (100*(number)/time);

}

if (percent>100) {

percent=100;

}

}

// Boarder Around The Progress Bar

void Boarder() {

noFill();

stroke(0);

rectMode(CENTER);

rect(width/2, height/2, width/2+10, height/10+10);

}

// Drawing The Text

void Text() {

//Percentage Text - Increasing by 5%

fill(0);

if (int(percent)<100) {

int percentForText = round(percent/5)*5;

text(percentForText + "%", width/2-10, height/2+10);

}

// Text When The Progress Bar Reaches 100%

else {

fill(255);

text("100% Done!", width/2-60, height/2 + 10);

}

}

Thanks Guys

Appreciate this
