get started already! stop being so freakin afraid!

2D arrays

2D arrays are initialized with nested brackets, like this:

let mut onlyGoodBattleRoyale:[[str;2];3] = [["99";2];3];

outputs something like

[["99","99"],
 ["99","99"],
 ["99","99"]]

NOTE: inner = columns, outer = rows

Therefore, to create the game grid...

let mut grid:[[i32; 10]; 40] = [[0; 10]; 40];

Yes, the grid is 40 blocks tall in Guideline T*tris. This is because of garbage lines.

The 2D arrays themselves are accessed the same way as in Java.

onlyGoodBattleRoyale[1][1] = "Crab Game"

results in

[["99","99"],
 ["99","Crab Game"],
 ["99","99"]]

Yes, I think Crab Game is a battle royale. Don't @ me.

Tetrominos

Did you know that filling a rectangle with one set of tetrominoes is impossible?

An idea is to do something similar to Tetrjs, but store rotations as well. Can never have enough bloat.

For example, the T piece would be something like:

000  040  000  040
444  044  040  440
040  040  444  040

Replacing the 0s with .s to make it clearer:

...  .4.  ...  .4.
444  .44  .4.  44.
.4.  .4.  444  .4.

Yes, it's ARS! (Arika Rotation System)

This may also be possible by coding specific offsets for specific rotations...

WOULD-BE-COOL: Symmetrical ARS. I don't like that there's a right side bias. Yes there is a right side bias in TGM. DTET already does something similar, but I'd prefer rotation button decide the horiz offset than rotation state.
