twistCube: Twist cube

In rcube: Simulations and Visualizations of Rubik's Cube (with Mods)

Description

Twist the cube by given string of moves and number of times.

Usage

twistCube(cube, moves = "", times = 1)

Arguments

cube	- cube object
moves	- string parameter Syntax: The main QTM clockwise movements are the same as in the Singmasters notation: "U", "D", "F", "B", "R", "L". However moves from HTM such as U2 is not move of upper layer by 180 degrees (it will be explained further). Counter clockwise moves are denoted by lowercase letters: "u", "d", "f", "b", "r", "l". Rotations of the cube are denoted by "O" (rotate cube horizontally, "o" means rotation horizontally in different direction); and "P" (rotate cube vertically, "p" means rotation vertically in different direction). Repetitions of the moves: there are several ways to repeat given sequence of moves. The simplest way is to copy commands. The most effective way to do this is using parameter times. However, in some cases it is useful to repeat only parts of sequence of moves - then we could use bracketing terms and operator times "x".
times	- integer (default is 1). Number of repetitions of moves.

Value

cube - cube object

Examples

# Create classic Rubik's cube:
c <- createCube()
# Check moves LL FF RR BB
c <- twistCube(c,"LLFFRRBB")
# Check if LFRB repeated 316 times is cycle:
c <- twistCube(c,"(LFRB)x316")
is.solved(c)
# TRUE
# Twisted chicken feet pattern:
c <- createCube()
c <- twistCube(c,positions[21,"moves"])
plot3dCube(c)
# The same pattern using pipe %>% from magrittr package
require(magrittr)
createCube() %>% twistCube(positions[21,"moves"]) %>% plot3dCube()
# Rubik's Revenge
createCube(N = 4) %>% plot3dCube()
# Creating Professor's Cube
createCube(N = 5) %>% plot3dCube()
# Rotating and moving edges:
createCube(N = 5) %>% twistCube("(u3RUrFrfRU3)x12") %>% plot3dCube()
# Moving and rotating edges part 2:
createCube(5) %>% twistCube("((R1:2)x2 BBUU (L1:2)x2 UU rr2
UU RR2 UUFF RR2 FF ll2 BB (R1:2)x2 )x2 dd") %>% plot3dCube()
# Hearts pattern on a cube sized 13x13x13:
createCube(13) %>% twistCube("OP U2
l4:5 R4:5 u2 L4:5 r4:5 U3
l3:6 R3:6 u3 L3:6 r3:6 U4

# Creating octa cube
createCube(N = 4, mode = "octa") %>% plot3dCube()
# Rotating centers which is not visible on a classic cube (URL algorithm):
createCube(N = 4, mode = "octa") %>% twistCube("(URLuurl)x2") %>% plot3dCube()
# Creating void cube 8x8x8
createCube(N = 8,mode = "void") %>% plot3dCube()
