The best way for coordinates?

Hello,

I'm currently trying out what the best way to create coordinates is.
When I tried it myself I got something big, that mainly had if statements:

When I asked my father he replied "Arrays" but didnt explain it…
Help?

Thanks in advantage.

In Lua, that would be tables. So you could do something like this to create the coordinates

coordinates = {x = 1, y = 12, z = 13}

then to get the x coordinate of whatever, you can do

coordinates.x

and that applies to every axis.
