No. I need to see the entire class. There is no Shield instantiation in what you gave above.

Okay, use of the 'addedToWorld' method was suggested at the time it was thought that the shield was to stay in the world as long as the warrior existed. Even then, only the first line was supposed to be in that method (the rest was for the act method). Because the shield is only in the world when a direction key is down, you will not use that method. All the code you have commented out within that method, except the first line, is to replace all the code in your act method down to line 88.

i have done that and it works but how do i spawn the shield in front of the character so it looks like a shield

Those two lines handle that: 
if (shield.getWorld() == null) getWorld().addObject(shield, getX()+30*dx, getY()+30*dy);
else shield.setLocation(getX()+2*dx, getY()+2*dy);
You changed the 2's to 30's in the first line, you have to use the same numbers in the second line.
