Hitting the white ball straight regardless of side

Questions & Answers
1

Hey guys I hope someone can help this has been doing my head in for hours! I am trying to hit the cue ball straight regardless of whether you hit the cue ball on the far right, far left or centre, they should all send the white in a straight line as if I hit the cue ball in the middle of the white. I am adding my own force like this:

Vector3 forceDirection = cueTip.transform.up;
forceDirection.y = 0;
rb.AddForce(forceDirection*1000, ForceMode.Impulse);

I drew a line from the cue ball in the direction of CueTip.up and this is the correct line, however when I hit the ball the force does not send the white straight like I want, can anyone see why?

Here is an example:

The left image is what is happening, but I want the the right image effect, from what I can see above I have no idea why the left is happening because the cue would be pointing straight forward not to the left.

Hi,

Your code does exactly what it says : it “adds force”… to the force already applied when your cue hit the ball initially (which already sent it off in the left direction).

Make sure your cue doesn’t add any force at all when hitting the ball and apply your custom force only
