Flipping the force vector in the pool example, can't make it work

Solar2D General Questions/Discussion
#1

In the pool example, the ball gets a force this way:

t:applyForce( (t.x - event.x), (t.y - event.y), t.x, t.y )

This is because it goes in the direction opposite from the touch coordinates, and this i understand.
I’m playing with it and I’m trying to have it shoot the ball exactly in the direction of the touch

t:applyForce( event.x, event.y, t.x, t.y )

It kinda works, but after the first applied force it behaves in a strange way, it may be that I don’t really understand exactly the way this force is applied, so I’m asking: how should I do it?

Is it possible to set an angle and a velocity like 90* force of 100 joules?

Try replacing that line with this line;

[lua]t:applyForce( event.x-t.x, event.y-t.y, t.x, t.y )[/lua]

That should do the trick :slight_smile:
