it says where i said it cant find it
<< Quote Omitted >>
how would i call that since this method is in the "OpenableDoor" class

how would i create an openable door
public boolean allowCollision()
{
if (isTouching(OpenableDoor.class))
{
OpenableDoor door = (OpenableDoor)getOneIntersectingObject(OpenableDoor.class);
if (door.isOpen())
{
return true;
}
else
{
return false;
}
}
}// says missing return statement
I've tried calling the method but i can still walk through it can i make it so cant until its open?
Post revised OpenableDoor and Characters classes. Also one of its subclasses (the one you tested, preferably).

Okay, in Characters class, remove line 10 and replace lines 7 thru 49 with:
In line 54, add 1 to the value set to newX ( "... = 1+ ..." ).
In ALL subclasses, immediately after calling movement method (insert after line 19 in Betty class above), add the following line:
public void act()
{
OpenableDoor door = getOneIntersectingObject(OpenableDoor.class);
if (!door.isOpen()) stopByOpenableDoor(door);
}super.act();
public void act()
{
OpenableDoor door = getOneIntersectingObject(OpenableDoor.class)incompatible types; greenfoot.Actor cannot be converted to OpenableDoor;
if (!door.isOpen()) stopByOpenableDoor(door);
}incompatible types; greenfoot.Actor cannot be converted to OpenableDoor
