Still Some Trouble Creating Gravity

[Filthy_Utter]

I'm glad it's Peter_B here to save the day yet again.

As for the complicated switch.. I know it's horrible x.x
I was really trying to get things working correctly before going to clean up (for some reason--making it hard on myself).

I planned on creating classes and doing simply class.mass()
But I might do a quick implementation of a function call to simplify things for me for now!

As for the next part, I'm not sure how to multiply the G*M1*M2/R^2 by vector V.
I did a quick Google to find that normalizing is simply dividing each of the components by the length--so dividing each one by r would do it I believe, or would it be dividing by tempForce?

I think it would be r, as you said the distance from object 1 to object 2.

But how would I go about multiplying by the vector? Sorry for the utter ignorance on the subject of vectors, but thanks so much for your help again!

Also, did you mean to put the - in front of the equation G*M1*M2/R^2 * V ? It's meant to be negative?
