public void attack()
    {
        if (Greenfoot.isKeyDown("space"))
        {
          if(Touching == false)
          {
              if (isTouching())
            {
              remove();
              setLocation(401,301);
              Touching = true;
            }
            else
            {
              move(1);
              Touching = false
               
            }
          }
        }
    }
this is what ive done, the parts i can't do are the bits where it says is touching() and remove()

i want to make it so that when you eat one and get moved back, you don't go forward again if you hold the space bar for a fraction too long, and that you have to let go of space and hold it again to move

I get the feeling that you overcomplicated things here. You can use the state of the key to determine whether to move or remove, meaning that the 'Touching' field is not needed at all:

if (Greenfoot.isKeyDown("space"))
{
    if (isTouching(Enemy.class))
    {
        removeTouching(Enemy.class);
        setLocation(401, 301);
    }
}
else
{
    move(1);
}

By the way, you can 'edit' your last post instead of creating multiple posts.

is there a way to make it so that the player, after eating an enemy, and gets moved back, it stays there rather than moving forward a bit after if you hold it down for a bit too long? because if not i can just put it so that i can press a key to make it go to the middle

With the code I supplied, your player will not move until the key is released.

sorry, i must have mislead you, is there a way i could have it move when the space key is down, but after it is move to the middle, it wont move unless the key is released and pressed again?

I think you will need two boolean fields, then -- one for the state of the key and the other for the state of waiting for keypress (or, in a holding pattern):

// instance fields
boolean spaceDown, spacePressed;
 
// act code
if (Greenfoot.isKeyDown("space") != spaceDown)
{
    spaceDown = ! spaceDown;
    if (spaceDown && ! spacePressed)
    {
        spacePressed = true;
    }
}
if (spaceDown && spacePressed)
{
    move(1);
    if (isTouching(Enemy.class))
    {
        removeTouching(Enemy.class);
        setLocation(401, 301);
        spacePressed = false;
    }
}
