Is their anyway to hold a vector2 in a type?

type skater
direction_vector as vector2
endtype

Thats kind of what I'd like to do, but of course that doesn't work. It appears that I can only hold floats, integers and strings in types. Bummer.

Vectors are not true types, so you won't be able to do that. Why not hold the vector number instead in an integer?

type skater_t
direction_vector as integer
endtype

dim skater(10) as skater_t

skater(0).direction_vector = 1
null = make vector2 skater(0).direction_vector

because you need to actually hold the Vector pointer Ian



you only need the vector number for creating them, when you destory them you need the pointer, it took me a few attempts when learning about the vectors to figure that.

however if all you want is a vector data setup



try to make sure when you exit the program you delete vectors.
delete vector pVecDir should be all you need

I pride myself that i don't kill...
well not without a good reason

Ok, this is WIERD! What is actually going on here? What is vec2count?

I guess what I'm surprised about is that you don't have to say:
Skater_t.direction_vector=make vector2(vec2count)

Does this imply that I cannot have any other structure member named "direction_vector"?

I guess I'm really confused...

That's not right Raven. If I put in this code:



I get the number '1' displayed twice. I suspect that you're getting the built-in vector system and your own system confused, as I have used vectors to great effect using my understanding of them. In my experience, the MAKE VECTOR* functions always return a '1', not a pointer.

iaretony, just treat vectors in the same way as you would deal with an object - you have to create it, update/modify it and delete it. The number that you assign to the vector is up to you

yeah probably... i've been using dx ones alot recently does get confusing - but i've had problems with DBPs builtin vectors quite a bit - i swear they change per version
