It's fairly simple to use Newton's equation to determine the attractive force between two objects.

But that's where I got stuck...

I have two spheres of known size, mass, and position.

Using Newton's equation, I know the amount of gravitational force pulling them together.

I also have a function that allows me to apply force to an object.

Now here's where I get stuck... the force I apply to the object has be in the format of (x,y,z) with the amount of force on each axis inputted.

If I remember my math correctly, I have to use a trig function here, probably a cosine... But I can't remember exactly how.

Here is my code so far:



Now I just need to use this function somehow to compute how to move my objects:

ApplyForce(Object,x,y,z);

Where x is the force applied to the x axis, and so forth.

I need to figure the equation, using my TotalForce number, to figure out those 3 axis inputs.

I think you are using my lib so I posted on that thread so it may help other people also.
