They are fairly simple to use really ...



If you have a more specific question just ask

This is a bit imprecise but I tend to see the Vector3 data item as being equivalent to the following DB Pro code:

TYPE Vect3

x as float
y as float
z as float

ENDTYPE

dim Vector3(100) as Vect3

So a = Y Vector3 would be the same as a = Vector3(x).y in the example above.

That's it really. The built-in vectors just have the advantage of having all the commands already written for you

Is there a way to like have to points in 3d space
and move a number or numbers to those points.
like a good collision systim.

they say things like a vectore is that line between
to points in 3d space.

What I wont to do is make some type of collision using them.

What I should say is in what way can I use them for a collision systom?

No, you can't use them to write a collision system really. Vectors are just used to hold positions (or offsets) or angles. They are just relatively easy to perform certain operations of.
