EDIT: posted at same time! I'll leave it in for others.

OK...I need to make some help files
. Create an emitter. Then create your effector. In the list of available emitters, double-click to make the "connection" between the 2. It will be marked with an "X" to show that th e2 are now connected. Double-click again to detach.

Basic emitters can be "pointed" using the rotation controls at the bottom. Then you can set the velocity. Box emitters aren't directional. You could use a force effector, which is a constant force rather than gravity which is progressive. You would probably want to activate Falloff, so that it didn't accelerate out of control. Wind might also be an option, as this caps the maximum velocity.
Quote: "And lastly, is it possible to rotate emitters/effectors"
See above, but also...There are 2 bugs in the particles pack. The position resets itself to zero every update
. So you must save the desired position in variables and reapply all the time. Secondly, rotation doesn't work at the moment. So for the rain, I had to make the emitter and wrapround effector big enough to cover the screen area as the camera rotated, and the effector became "diamond" shaped in relation to the camera.
These should be fixed in the next update, both confirmed in Bug Reports.
Glad you're having fun! I plan to update my app with a more featured version soon. I don't think it is worth marketing yet, so look out for a better, free version soon.
