square chasing square

[clarence144]

Ok, I have this game, and some levels have a moving square as the player, you move the square with your arrow keys....

Ok, so I want to have an enemy square that chases the player square....

Anyone remember the ghosts in mario? They only chased mario when you didn't look at them? Kinda like that...... but in this regards:

I only want the enemy square to chase the player square when the player square moves.... soo say the player square moves 5 pixels per movement (know how to do all that), I want the enemy square to move when the player square moves..... towards the player square at like 7 pixels per movement..... so eventually you won't be able to avoid the enemy square....

Any ideas?

This would be GREATLY appreciated, thanks so much!

I want the evil 666 square to move towards the player only when the player moves....

Like I said, and ideas would seriously help me.

playerSpeed=5;
enemySpeed=7;
onEnterFrame=function(){
	if(Key.isDown(Key.RIGHT)){
		player._x+=playerSpeed;
		advanceEnemy();
	}else if(Key.isDown(Key.LEFT)){
		player._x-=playerSpeed;
		advanceEnemy();
	}else if(Key.isDown(Key.DOWN)){
		player._y+=playerSpeed;
		advanceEnemy();
	}else if(Key.isDown(Key.UP)){
		player._y-=playerSpeed;
		advanceEnemy();
	}
}
function advanceEnemy(){
	//move enemy toward player
	theta=Math.atan2(player._y-enemy._y,player._x-enemy._x);
	enemy._x+=enemySpeed*Math.cos(theta);
	enemy._y+=enemySpeed*Math.sin(theta);
	if(enemy.hitTest(player)){
		//the player was caught by the enemy
		trace("hit!");
	}
}
