I'm just to make this random movement stuff. The random code will genarate a number 1-4 and each of that number will move the object to 1 corner. here is what i have so far...

[swf x=400 y=150]http://www.geocities.com/ketchup66/flash/Movement.swf[/swf]

Problem:
After some times, all the object will move to the top left corner. It seem that the random number 2 and 3 is more popular then other. Could it be a mistake in my code?

Here is the key code:

Code:

 
CreatureX = _x;
CreatureY = _y;
if (Direction == 1) {
	CreatureY = CreatureY+Speed;
	CreatureX = CreatureX+Speed;
}
if (Direction == 2) {
	CreatureY = CreatureY+Speed;
	CreatureX = CreatureX-Speed;
}
if (Direction == 3) {
	CreatureY = CreatureY-Speed;
	CreatureX = CreatureX-Speed;
}
if (Direction == 4) {
	CreatureY = CreatureY-Speed;
	CreatureX = CreatureX+Speed;
}
if (CreatureX>390) {
	CreatureX = 390;
	Direction = (Math.random()*3)+1;
	Speed = (Math.random()*2)+1;
}
if (CreatureX<10) {
	CreatureX = 10;
	Direction = (Math.random()*3)+1;
	Speed = (Math.random()*2)+1;
}
if (CreatureY>140) {
	CreatureY = 140;
	Direction = (Math.random()*3)+1;
	Speed = (Math.random()*2)+1;
}
if (CreatureY<10) {
	CreatureY = 10;
	Direction = (Math.random()*3)+1;
	Speed = (Math.random()*2)+1;
}
DirectionChange = (Math.round(Math.random()*10));
if (DirectionChange == 1) {
	Direction = (Math.round(Math.random()*3))+1;
	Speed = (Math.round(Math.random()*2))+1;
}

_x = CreatureX;
_y = CreatureY;
