Pentomino rotations by game

Shirase Rotation System

A joke rotation system made by Makiki99. Take the wallkick system from SRS, then apply offsets to each of the rotation states. Luckily for us, the offsets are consistent:

State	Offset
Up	1 left
Right	1 up
Down	1 right
Left	1 down

ARS kick diagrams

Rotation	Counterclockwise		Clockwise
	Right	Left	Right	Left
S, h -> v
S, v -> h
Z, h -> v
Z, v -> h
L, d	Impossible	*	*	Impossible
L, l
L, u	*	Impossible	Impossible	Impossible
L, r
J, d	Impossible		*	Impossible
J, l
J, u	Impossible	Impossible	Impossible	*
J, r
T, d	Impossible	Impossible	Impossible	Impossible
T, l	Impossible
T, u	*	Impossible	Impossible	*
T, r				Impossible

The centre column rule is ignored if the piece kicks off a block in a row above the appropriate centre column block, but not below (presumably due to block precedence.

180 degree rotations in SRS

Official SRS

Due to how the rotations in SRS are constructed, 180 degree rotations are well defined in SRS, though no official game implements them.

(Recall that values are given as x shift then y shift, with right and up positive.)

J, L, S, T, Z Tetromino Wall Kick Data

	Test 1	Test 2	Test 3	Test 4	Test 5
0->2	( 0, 0)	( 0, 0)	( 0, 0)	( 0, 0)	( 0, 0)
2->0	( 0, 0)	( 0, 0)	( 0, 0)	( 0, 0)	( 0, 0)
L->R	( 0, 0)	(-2, 0)	(-2, 0)	( 0, 0)	(-2, 0)
R->L	( 0, 0)	(+2, 0)	(+2, 0)	( 0, 0)	(+2, 0)

Due to the symmetric locations of the rotation points, there are no kicks in states 0 or 2, and only one in states L or R.

I Tetromino Wall Kick Data

	Test 1	Test 2	Test 3	Test 4	Test 5
0->2	( 0, 0)	(-3, 0)	(+3, 0)	(-3,+1)	(+3,+1)
2->0	( 0, 0)	(+3, 0)	(-3, 0)	(+3,-1)	(-3,-1)
L->R	( 0, 0)	(-1, 0)	(-1, 0)	(-1,-3)	(-1,+3)
R->L	( 0, 0)	(+1, 0)	(+1, 0)	(+1,+3)	(+1,-3)

Note that when the I is vertical, Test 2 maps the piece onto itself and thus this is in fact the only kick possible.

Reduced tables

This is why official SRS is fundamentally incompatible with 180 degree rotations.

J, L, S, T, Z Tetromino Wall Kick Data (reduced)

	Test 1	Test 2
0->2	( 0, 0)
2->0	( 0, 0)
L->R	( 0, 0)	(-2, 0)
R->L	( 0, 0)	(+2, 0)

I Tetromino Wall Kick Data (reduced)

	Test 1	Test 2	Test 3	Test 4	Test 5

2->0	( 0, 0)	(+3, 0)	(-3, 0)	(+3,-1)	(-3,-1)
L->R	( 0, 0)	(-1, 0)
R->L	( 0, 0)	(+1, 0)

SRS-X

Compare the rotations in SRS-X from Heboris UE. Note that the code specifies down as positive; this has been adjusted for this table.
