Make Object Move

Hi,

does anyone know the proper way to touch an object and make it move in any direction you want?
what i`m trying to do to be more specific is touch a ball and toss it in any 4 directions up down left right.
I dont want to drag the object around the screen it will kill the purpose of my game i want it to move by me touching the object.

so far what I have tried is function ball = event.target and set ball.setLinearVelocity(0, 200) and add
event listener touch to ball so when i touch the ball it moves down but if i change it to
ball.setLinearVelocity(200, 200) instead of moving right and down when ball is touch it will move in a
corner direction.

(example) basically I want to fling the ball up , down , left , right to knock down a object.

Thank you for help and time to anyone who will kindly help me in this topic as i`m new to corona and programming [import]uid: 30314 topic_id: 6180 reply_id: 306180[/import]
