Im making a flappy bird game and I want to make it so that when I press space it could just move up somehow

If the current location of an actor is: ( getX() , getY() ) then a location of distance 'd' above it would be: ( getX() , getY() - d )

if(Greenfoot.isKeyDown(up)){
            setLocation(x,y+a);

The isKeyDown method of the Greenfoot class requires a String type parameter:

1	`if` `(Greenfoot.isKeyDown("up")){`
