what's the proper way of declaring a vector in lite-c? or
Is it
a) VECTOR temp;
b) VECTOR* temp; ..... ?

Is there a scope where it is declared for either declaration syntax?

I've seen some sample codes using (a) and/or (b)...
I try to declare a global vector using (a), it works fine.
Then, i try also declaring a global vector using (b).. it crashes!

just for clarification. Thanks

Ive had great difficulties with the vector over time too.
To the best of my knowledge, which is far from perfect

Use version A when it is a local variable.

Use version B when it is a local or global POINTER, and is just going to point at other vectors. (uncommon)

Use version A when it is a global variable, but you dont care about its initial value. (dirty!)

Use version C when it is a global variable, and you want to set its initial value.
Version C is VECTOR* temp = { x=0; y=0; z=0; }

In version a) you declare a vector. In version b) you declare not a vector, but an empty pointer. Using empty pointers in functions will CRASH. So, there is no sample code for b) unless you want to learn how to crash the engine.

Sample code for a:

function foo()
{
VECTOR v;
vec_set(v,vector(1,2,3));
vec_add(v,v);
...
}

and so on...

When you really want to use pointers, you must always let those pointers point to something... otherwise, CRASH!!

VECTOR* v; // empty pointer, points to nothing
vec_set(v,vector(1,2,3)); // crash!

but

VECTOR* v = { x = 0; y = 0; z = 0; } // now v points to a real vector
vec_set(v,vector(1,2,3)); // no crash!

Hope this helps..

Thanks for the info.

wow thans to both of you!
I was using mostly version b (dont know why it dosnt always crash), and when I did get a crash I would change to option a (but didnt understand why I had to do so).
Now I know why each one is used, thanks!

Actually you can read all about this stuff at AUM 82 under PLUG and PLAY then lite-C pointers..
