Turtle Graphics Program

[JulianP]

Hi I am working on a Turtle Program and I have put in all the fancy schmancy stuff in I just cant seem to figure out how to print the T, which is my turtle, on the screen. Here is the code for my program so far!

made a few modifications to your program - as you type right the T moves across the pattern - is this what you require?

Thanks,
I was looking for it to print a T when i put in left,right,up, or down.

not sure if what you did actually does something... I can see where your headed but right now it doesn't display a T when I type in right. I am useing Textpad if that helps at all.

Sorry for being the dumb one here but could you please repeat again what you want to be printed where when what happens?

[JulianP]

In my program I am setting up a JTextField whith an array of [20][20] and it fills it with 0's. Right now I want it to start in the top left corner and when you type in the command right,left,up,d own it will replace the 0 with a T. Here's a Copy of the program agian.

                               input.append(pd);
                               ent.setText("");
                               //if(xpos < 10 )xpos++;   // ** addded
                               floor[xpos][ypos]=1;
                               print();
                        }// ** end pd
 
 
                         if(ent.getText().toLowerCase().compareTo("pen up")==0)
                       {
                               pd ="(PEN UP)\n";
                       System.out.println("Pen Up");
                               input.append(pd);
                               ent.setText("");
                               //if(xpos < 10 )xpos++;   // ** addded
