Building first app, general help needed.
Hi, im real new to this and have no clue what im doing. I have a java file that does a real simple tic tac toe game with a server. I have to figure out how to install this program on my BB 8330. I was wondering if someone could give me some pointers or steps on what i have to do. The code was written as a Midlet i think and is supposed to be a general java phone app. Just not sure how to install it on my phone. Here is the code in the java file:
Code:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import java.io.*;
import java.util.*;
interface Constants
{
public static final int CONDITION_WIN = 255;
public static final int CONDITION_LOST = 254;
public static final int CONDITION_DRAW = 253;
}
class TicTacCanvas extends Canvas implements Constants
{
private TicTacClient app_;
public TicTacCanvas(TicTacClient app)
{
app_ = app;
}
public void paint(Graphics g)
{
int linesx, linesy, lineex, lineey;
int circlecx, circlecy, circler;
g.setColor(255, 255, 255);
g.fillRect(0, 0, getWidth(), getHeight());
g.setColor(0, 0, 0);
//g.drawString("Hello World!", 0, 0, Graphics.LEFT | Graphics.TOP);
int i, j, contents;
int skipX, skipY;
g.setColor(0, 0, 0);
//Draw lines of tic tac toe board
skipX = getWidth() / 3;
skipY = getHeight() / 3;
//Draw game board lines
for (i = 1; i < 3; i++)
{
linesx = i * skipX;
linesy = 0;
lineex = i * skipX;
lineey = getHeight();
g.drawLine(linesx, linesy, lineex, lineey);
for (j = 1; j < 3; j++)
{
linesx = 0;
linesy = j * skipY;
lineex = getWidth();
lineey = j * skipY;
g.drawLine(linesx, linesy, lineex, lineey);
}
}
//Draw Xes and Os
for (i = 0; i < 3; i++)
{
for (j = 0; j < 3; j++)
{
contents = app_.gameBoard[(j * 3) + i];
if (contents == 1)
{
//Draw blue X
g.setColor(0, 0, 255);
linesx = (i * skipX) + 2;
linesy = (j * skipY) + 2;
lineex = ((i + 1) * skipX) - 2;
lineey = ((j + 1) * skipY) - 2;

if (skipX < skipY)
circler = skipX / 2;
else
circler = skipY / 2;
circler -= 3;
//note the ridiculous gymnastics we have to do to draw a simple circle
g.drawArc(circlecx - (circler), circlecy - (circler), circler * 2, circler * 2, 0, 360);
}
}
}
//If we are waiting for something, notify user
if (app_.winner != 0)
