Is this for something like pool?
You might be able to use a 2D physics engine to get this working. APE is really
easy to pick up and run with, and Box2D has a pretty good feature set, though
the API could certainly be improved.

But from what I tried, the impulse seems to have the hugest problem
with the direction of where the object travels after, 'cuz whenever I
modify it even a bit, the entire direction will screw up in ways that
I dislike strongly... According to what I read, they said that delta
refers to the "offset vector" or something? Couldn't understand that
bit that well either...
.applyBodyWorldImpulse(impulse:JNumber3D, delta:JNumber3D):void
My code looks like this now by the way
var shotPower = shotChargeNum * 5000 * stick.mass
var minShot = 5000 * stick.mass
var xShoot = (shotPower) * Math.sin((stick.rotationY) * Math.PI /
180.0)
var zShoot = (shotPower) * Math.cos((stick.rotationY) * Math.PI /
180.0)
trace(xShoot)
trace(zShoot)
var shootVector;
shootVector = new Vector3D(xShoot / shotPower, 0, zShoot / shotPower)
trace(shootVector)
myCueBall.applyBodyWorldImpulse(shootVector, delta);
P.S By the way, the numbers that I get from this is ENORMOUS. as in,
5-6 digits huge, 'cuz I set the mass of the stick ot a huge number
because smaller masses seem to make it get pushed partially by the
stick, causing the direction to deviate...

as i remember "delta" is force direction, and you can use applyWorldImpulse
or applyBodyWorldImpulse for this
