need a bit help! ;)

Hi,
i just started to learn fenix and im working a bit on a Zelda like game..
i do this with help of a tutorial.

i use this code to move the charakter

Code:

---

if (key(_right) and not key(_up) and not key(_down))
x=x+2; angle=0;
if (graph<=2 or graph>=7) graph=2; end;
graph++; flags=0; angle=0;
end

---

now the problem is, that if you dont press the button anymore, the last sprite which was drawn stays on the screen and that looks sometimes a bit strange..
so i want to add a bit more code to this..
graph = 1 should be drawn after moving...
how i can do this?

Well, I don't know perfectly what are you asking, because the code you paste is very abstract... but I've made something that can help you

Code:

---

program zelda_clone;
Begin
 Set_title("Zelda Clone");
 Full_screen = FALSE;
 Graph_mode = mode_16bits;
 Set_mode (m640x480);
 load_fpg("myfpg.fpg");
 chara();
end

PROCESS chara()
// graph=1 when character is standing, graph from 2 to 4 when is walking
// graphs originally drawn with character head looking up

PRIVATE walking;

BEGIN
x=320;
y=240;
graph=1;
 LOOP
 IF (key(_right))
  x=x+2;
  angle=270000;
  walking=1;
 END
 IF (key(_left))
  x=x-2;
  angle=90000;
  walking=1;
 END
 IF (key(_up))
  y=y-2;
  angle=0;
  walking=1;
 END
 IF (key(_down))
  y=y+2;
  angle=180000;
  walking=1;
 END
 IF (NOT (key(_right)) AND NOT (key(_up)) AND NOT (key(_down)) AND NOT (key(_left)))
  walking=0;
 END
 If (walking==1)
  graph=graph+1;
 END
 IF (walking==1 AND graph==5)
  graph=2;
 END
 IF (walking==0)
  graph=1;
 END
 IF (key(_esc))
  exit("",0);
 END
 frame;
 END
END

Hope this can help, I think that there is another easiest way to make this, but I'm asleep (I retourned from vacation today, have to return early...)
