[java] asci for arrows
Author
does someone know the asci code for the arrows?
or is there a better solution if you use Keyevents e
e.getKeyChar(),
I have tried to find the asci code myself but I get for the 4 arrows the same number 65535 ?!??
I don''t believe that arrows are a standard ASCII code. You can check out this page[asciitable.com] for a nice big table of ASCII characters and the numbers associated with them.

Try Event.LEFT, Event.RIGHT, Event.UP, Event.DOWN
These are all static int''s from the event class that define the value of those keys.

Or KeyEvent.VK_DOWN and KeyEvent.VK_UP and KeyEvent.VK_RIGHT and KeyEvent.VK_LEFT
For the numeric pad, KeyEvent.VK_KP_DOWN and KeyEvent.VK_KP_UP, etc. Cough, sorry about the other post somehow I had thought you were looking for an ASCII character that looked like this: ''->'' or something.

e.getKeyChar() only displays printable characters. The arrows are not printable. They also do not generate an ascii code in the traditional sense. If you do programming in ''C'' you will notice that when you run printf("%d",getc()); in an infinite loop and press and arrow, it throws out a ''0'' first, then a second number representing the arrow key. The ''0'' is like an escape character. I don''t think you can pick up on this in Java.

Easy, just convert the char to an int and print the dam thing from a FRAME or JFRAME, but hay here are the values any way....
public static final int key_insert = 1025;
public static final int key_delete = 127;
public static final int key_home = 1000;
public static final int key_end = 1001;
public static final int key_pageup = 1002;
public static final int key_pagedown = 1003;
public static final int key_left = 1006;
public static final int key_right = 1007;
public static final int key_up = 1004;
public static final int key_down = 1005;
public static final int key_backspace = 8;
NOTE: you will have to detect your own controls and shifts at the key event level.

As pirate_dau said, use the KeyEvent.VK_UP, etc.
To determine which of these keys was pressed use the getKeyCode() method instead of the getKeyChar() method (which only returns UNICODE characters).

Well, this won''t be much help for Java, but if anyone wants to know the good ol'' dos ascii codes for the arrow keys, here they are:
up: 0, 72
left: 0, 75
right: 0, 77
down: 0, 80
where 0 is the escape code (each key is two bytes instead of one)
it took me a long time to figure these out for my first QBasic game, but i''ve got them down pat now
