Hi friends I am making an game in which many object will be moving in my screen ( like mouse hunt ) i have to select them and through it out of the screen and the object should move in which direction I am moving my finger.

Can any one tell me how i should get the direction in which rest of the movement should be made.

1. On the initial touch set that point as your origin
2. Track the movement and when you pass a certain distance from your origin you can make it your direction vector (p1 - p0)
