I am in need of some help with my processing program I am developing for a college assignment.
I have three classes in total. I have my main class which draws the program and runs it. I then have my client class which is used for the printing of the text and finally I have a read file which reads the input from the external text file.
I have the program running perfectly and have been playing around with it and I did get the program to print out numbers(coordinates) from an external file. However the document specification is text from an external file.
Also if anyone has any good ideas what I can do in regards to taking input from the keyboard as that is part of the specification
I have basic knowledge of Java and have started using processing with it recently so I would appreciate some help with this please.
This is my main class called SoccerCode.
import processing.core.PApplet;
public class SoccerCode extends PApplet
{
PApplet parent;
int posX,posY, velX, velY;
float mida =6;
float mida1 =10;
public void setup ()
{
size (300,150);
posX = width /2;
posY = height/2;
velX = 2;
velY =2;
}
public void draw ()
{
background (0,190,0);
line (0,0,300,0);
line (300,0,300,150);
line (300,150,0,150);
line (0,150,0,0);
line (150,0,150,150);
noFill();
ellipse (150 , 75 , 6,6 );
ellipse (150 , 75 , 35,35 );
ellipse (0 , 75 , 100 , 100 );
ellipse (300 , 75 , 100 , 100 );
stroke (220);
strokeWeight ( 5);
posX = posX+velX;
posY = posY+velY;
ellipse(posX,posY,mida,mida);
if((posX<6)||(posX>width))
{
velX = -velX;
}
if((posY<6)||(posY>height-6))
{
velY = -velY;
}
if(mousePressed==true)
{
rect (0,mouseY,mida1,20);
rect (290,mouseY,mida1,20);
}
}
}
Here is my client class
import java.io.File;
import java.io.IOException;
import processing.core.*;
import java.io.BufferedReader;
public class Client extends PApplet
{
public void main() throws IOException
{
String file_name = "text.txt";
try
{
ReadFile file = new ReadFile(file_name);
String[] aryLines = file.OpenFile();
int i;
for(i=0; i<aryLines.length; i++)
{
System.out.println(aryLines[i]);
}
}
catch (IOException e)
{
System.out.println(e.getMessage());
}
}
}
Finally my read file class:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class ReadFile
{
private String path;
public ReadFile(String file_path)
{
path = file_path;
}
public String[] OpenFile() throws IOException
{
FileReader fr = new FileReader(path);
BufferedReader textReader = new BufferedReader(fr);
int numberOfLines = readLines(); //Uses the readLines method to fill the data.
String[] textData = new String[numberOfLines];
int i;
for (i=0; i<numberOfLines; i++)
{
textData[i] = textReader.readLine();
}
textReader.close();
return textData;
}
int readLines() throws IOException
{
FileReader file_to_read = new FileReader(path);
BufferedReader bf = new BufferedReader(file_to_read);
String aLine;
int numberOfLines = 0;
while((aLine = bf.readLine()) != null) //Reads the lines of text and if the next is null loop ends.
