Hy , im currently in the design phase of my 2d "basketball game" project. Can any1 tell me some tutorial (or to post some simple class with 2 vectors that can be added or whatever) on 2D vectors (im not talking about arrays). I can perform operations with them on paper but how to code that i have no clue, thx in advance.

I think you have bigger problems if this is giving you trouble.

It's just a struct with a couple simple functions. Look into classes and operator overloading.

that was helpful thanks,

it thats so simple help me out: a bullet thats described by line0 (POINT a, POINT b) with velocity=5 is hitting a wall at a 30 degree angle (as an example), bounce that back , i'm not saying its rocket science either.

I hope that make at least any sense

Thats a physics caluclation and slightly different from your first question.

Make your vector a class not a struct, internally to C++ structs are classes anyway but they arent in C, so use classes instead of structs as they support proper protection level.
