Hi guys,

Just wondering if there is any built-in commands for handling 2D vectors? I ran around in the documentation looking for it, but can't seem to find anything. I'm not the best coder, so I'm not really sure where to start if I need to manage them myself. I know with DBpro we had MakeVector or something like that...is there a similar command for AppGameKit?

If not, is there some way I can understand a little more how to create a vector data-type myself? I understand the direction and magnitude stuff...I think.

Any help would be great!

Cheers,
Greenlig

There are no built in commands for AppGameKit tier 1.

Here is an example for coding them yourself.

+ Code Snippet

type vectortype
    x as float
    y as float
endtype

v1 as vectortype
v2 as vectortype
v3 as vectortype


v1 = setvector(1.0, 2.0)
v2 = setvector(3.0, 4.0)
v3 = addvectors(v1, v2)

do
    print(str(v1.x))
    print(str(v1.y))
    print(str(v2.x))
    print(str(v2.y))
    print(str(v3.x))
    print(str(v3.y))
    sync()
loop

function setvector(x as float, y as float)
    vector as vectortype
    vector.x = x
    vector.y = y
endfunction vector

function addvectors(vector1 as vectortype, vector2 as vectortype)
    vector as vectortype
    vector.x = vector1.x + vector2.x
    vector.y = vector1.y + vector2.y
endfunction vector
