            !(playerY == -1 && scrollY == 0) &&
            !(playerX == 1 && scrollX == BIG_X-WIDE) &&
            !(playerY == 1 && scrollY == BIG_Y-HIGH)) scroll(playerX, playerY);
        // time delay when moving
        Greenfoot.delay(10);
}
if i do it like this, it throws me an error that the method playerY() cannot be found

Wow. You are using playerX and playerY for something totally different from what they suggest. I would think you might change x and y (see line 11) to them, not dx and dy. dx and dy are the changes in x and y (the player's position) determined by the key states.

At any rate, you should leave line 8 alone (not adding more conditions there). You can make those checks more simply after line 13: 
if (world[x+dx+scrollX][y+dy+scrollY] != 0) return;
