URGENT! PLEASE RESPOND! -- simple actionscripting problems

I really need some help on this, PLEASE HELP!!

// though it may look like i’ve made a sorry version of actionscript
// i have not. it’s just simple and brief description of what i’m trying
// to accomplish in this project.

Sprite.1 : your character, blue circle; movement = “up”,“down”,“left”,“right” arrow keys. <FINISHED>

Sprite.2 : enemy character, red square; movement = diagonals only; always toward Sprite.1.

END : Sprite.2 completely covers Sprite.1

Score : # of moves * 100

Mode change 1: @ score 6000 = PARANOIA MODE; score +2500pts; score = # of moves * 250. Background_color = Sprite.2_color.

Mode change 2: @ score 50000 = FREAK MODE; score +5000pts; score = # of moves * 500. Background_color changes between Sprite.1_color and Sprite.2_color every 3-15 frames.


basically what I need the most now, is to figure out how i get Sprite.2 to come towards Sprite.1 in a diagonal manner. this is what i have now:[indent]onClipEvent(keyDown){

if (Key.isDown(Key.UP)){
_x += 25;
_y -= 25;
}else if (Key.isDown(Key.DOWN)){
_x -= 25;
_y += 25;
}else if (Key.isDown(Key.LEFT)){
_x -= 25;
_y -= 25;
}else if (Key.isDown(Key.RIGHT)){
_x += 25;
_y += 25;
}
}

[/indent]its just that i want Sprite.2 to move toward Sprite.1 (like he’s chasing after him) just all this does it make it so they both follow the same direction. How can I do this?
