GRRRR! compile error!!!

[fred fredricks]

hey, i just cant see the error guys...maybe you can see and help me out? its between two files, so i hope you dont mind me posting both class's and the respective compile errors..

import java.awt.Graphics ;
 
abstract class Ship extends MoveableObject
{
  public Weapon shoot()
  {
    return myWeapon.shoot( this.x + width / 2 - myWeapon.getWidth() / 2 ,
                           this.y + this.height / 2 - myWeapon.getHeight() / 2 ) ;
  }
  
  public int getX()
  {
    return x ;
  }
  
  public int getY()
  {
    return y ;
  }
  
  protected Weapon myWeapon ;
}

Well, I tried to make some suggestions earlier, but you must have deleted your post before I finished...hehe, things happen like that sometimes.
Also, your new post gives me a better idea of what is going on. The compiler is still complaining that it can't find the getHeight() method. Is this implemented in the MoveableObject class? If so, please post it, too. Also be sure to use the CODE tags to preserve the indentation in your code. It sure makes it much easier to read.

hi, sorry, i didnt mean to do it...newbie, i am playin around trying to see what does what etc...thanks for the help...here is the other class

/*
// header - edit "Data/yourJavaAppletHeader" to customize
// contents - edit "EventHandlers/Java Applet/onCreate" to customize
*/
import java.awt.*;
/*
public class MoveableObject extends java.applet.Applet
{
public void init()
{
resize(300,300);
}
public void paint(Graphics g)
{
g.drawString("Hello MoveableObject!", 50, 50);
}
}
*/

import java.awt.Graphics;
abstract class MoveableObject
{
//Draw
abstract void draw(Graphics g);


//Move, specify the speed
public void move (int direction, int s)
{
if(direction == this.RIGHT)
this.x = x + s;
if(direction == this.LEFT)
this.x = x - s;
if(direction == this.DOWN)
this.y = y + s;
if(direction == this.UP)
this.y = y - s;
}

//Overloaded, use default speed
public void move(int direction)
{
move(direction, speed);
}

// True is this object is out of the given boundary
public int outOfBound(int xBound, int yBound, int h, int w)
{
if (x < xBound)
return LEFTBOUND;
else if (x+width > xBound+w)
return RIGHTBOUND;
else if (y < yBound)
return TOPBOUND;
else if (y+height > yBound+h)
return LOWBOUND;
else
return INBOUND;

}

//Accessor
public int getWidth()
{
return width;
}
public int getHight()
{
return height;
}

//States

protected int x;
protected int y;
protected int width;
protected int height;
protected int speed;

public static final int RIGHT = 0;
public static final int LEFT = 1;
public static final int UP = 2;
public static final int DOWN = 3;


public static final int RIGHTBOUND = 0;
public static final int LEFTBOUND = 1;
public static final int TOPBOUND = 2;
public static final int LOWBOUND = 3;
public static final int INBOUND = 4;

}

Okay, one problem is that MoveableObject needs to be declared public. If that doesn't fix all the problems, you should then remove all of your .class files and start the compilation over again. Sometimes this is the only thing necessary to fix such problems because some of the current .class files were generated from an old version of the code.

Schpellink eror: getHight() should be getHeight()
PS. Funny, I thought Laine was our spelling expert
:rotten joke: Sorry Layne, really
