i have been working on a game. I need to figure out how to get the character to collect things, they are little formula bottles, so the character moves and jumps to collect them. i can't figure out how to place the bottles. and how would the program count them? like keep track, but display the counter also. thank you

display the counter
My Value Display Tutorial should be able to give you some guidance.

Well, placing the bottles is something you really need to figure out (just do not place them where your character cannot get to them). As far as the count display, you need two fields and at least one method. The fields: (1) an int field for the count; and (2) a reference field for the Actor object used to display the count. The count field should probably be in the class of the character. The display reference field can be in either the same class or in your World subclass. The method is to adjust the score and update the display. This should be in the same class as the reference field.

I know how to get a character to move using the arrow keys. how do i do it using a,w,d keys? 
public void checkKey ()
    {
        if (Greenfoot.isKeyW ("right")) 
        {
            //direction =1;
            setLocation (getX()+speed, getY());
        }
        if (Greenfoot.isKeyDown ("left"))
        {
            //direction =-1l
            setLocation (getX() - speed, getY());
        }
        if (Greenfoot.isKeyDown("up") && jumping == false)
        {
            jump ();
        }
}
I know the .isKeyW is wrong, I don't know what to change it to get the character to move when the a,wd, keys are pressed

Just replace "right", "left" and "up" with "d", "a" and "w", respectively. Change "isKeyW' back to what it was before you tried something different.
