I point out the problem at the comments. Basically, I try to fill a list of table of custom objects (struct type QRSCoordinate) within another object (struct type Hexagon). The property name of the table of customs objects is lqrspoints. In the code below, when I try to fill up this table, the values are not saved in it. The code will show more of what I am trying to say.
here are the comments in the code pasted below which point out where the problem is:
//load created vertex into hex.lqrspoints table for the hex object that called this function
//something is not working here:
,
//test to see if hex.lqrspoints has been filled, as per console, it remains empty, and
//the console doesn't display any value for firstpoint.posq
here is the full code
typeof hexvqrsvectors= tab[I I I];;
struct XYVertex=[
posx: I,
posy: I
]mkXYVertex;;//this makes a vertex object with xy coordinates
struct QRSCoordinate=[
posq: I,
posr: I,
poss: I
]mkQRSCoordinate;;//this makes a vertex object with qrs coordinates. It is easier to create a grid
//of hexagons this way and you can use xyz vector functions with your hexagons
struct Hexagon=[
VQRScenter: QRSCoordinate,
Isize: I,
lxypoints: tab XYVertex,
lqrspoints: tab QRSCoordinate,
funcwithinbounds: fun [[Hexagon XYVertex]] I,
funmakeqrsvertices: fun [Hexagon] [tab QRSCoordinate],
funconvert_xy_to_qrs: fun [Hexagon][I I I],
funconvert_qrs_to_xy: fun [Hexagon][I I]
]mkHexagon;;
//this object will hold a bunch of hexagons in a grid in qrs coordinate system
//this will be very important to build a hexagon grid with hexagon .mesh object in os3d i think
