the link above leads to the file, just download that.

1) When you click on the "Generate" button a 15x21 board of Tile symbols is created, with top-left corner at (10,10). Initially all tiles should be blank.

2) Extend the functionality behind the "Generate" button so that a random configuration of walls appears - 100 of the tiles should now be "filled". Each time you click on "Generate" there should be a different configuration. Hint: create a map array initially consisting of 0's. Generate should randomly produce 100 pairs of (row, column) values where you set the value in the map array to 1. Use the map array to display the board.

3) Extend the "Generate" functionality even further. You should include in the application 4 instances of the Ghost symbol and one instance of the MyPac symbol. When you click on the "Generate" button, the ghosts should appear in each corner of the board, and the myPac should be in row 8, col 11 of the board. "Generate" should still produce a random configuration of 100 filled cells each time it is clicked, but the ghosts and myPac should always appear in the prescribed positions.

4) Finally, you should animate the ghosts and add key-handling for the myPac symbol. The ghosts should "patrol" the board ie they can move randomly in the array but cannot go through "walls" or myPac. The starting fla includes some code you might find useful for this part of the assignment. myPac should move with arrow-key presses, but also cannot go through walls or ghosts

i cant do the first 3 parts....part 4 shouldnt be too hard though 😕😕

guys if you can please help in any way.

thanks in advance.
