A question for those who are experienced with Vector2 commands; is there any real advantage through their use? Or is it really just as easy, (if not easier?), to manage all my data in my own structured UDT's complimented by custom written functions to perform the same calculations as the Vector2 commands.

Any thoughts on this subject would be most appreciated.

If you are able to do either, then write both functions. Loop them 100000 times and get both versions total completion times. Then just use the faster method.

There's an argument to be made about code complexity, but I usually side with performance.

Oh how interesting! I'm reading now that you can call a Vector3 return to replace X,Y,Z variables when using a camera commands, etc! I think I'm starting to see why Vector commands could be useful, as that looks like a pretty clear advantage.

Mage, good thinking with the test as well. Always the obvious things isn't it (well, with me it is... )!

I usually used my own functions/types because I had to call a function every time I wanted to access a single component of the variable instead of accessing a simple data structure. All those little function calls can eventually add up, especially if they have to be sprinkled throughout a 20,000 line project.
