 That's TGM, not SRS
In the 20g section, colour_thief added the example:
That's TGM rotation, not SRS. SRS would process it like this:
where the L tetromino rotates around its center (represented here as a yellow block). --Tepples 12:57, 21 June 2006 (EDT)
- Thanks CT for fixing it. But in my experience even at slower levels (TDS standard marathon level 1 and 11), the difference seems to be related to the game's slow ass DAS rather than a difference in processing order, as I get one or two frames of the "intermediate" state visible on the screen. --Tepples 15:08, 21 June 2006 (EDT)
- Thanks for the comments Tepples. Lots of TGM clones (all using 60 fps DAS) get this detail wrong because of misordering, so I may have been quick to jump to conclusions. After further testing it seems you are right, it is related to slow DAS. Well, it could be any number of DAS things really... Charge time, repeat rate... In TGM, a charged DAS will move on the first frame it can, while in TDS I think it waits for an amount equal to the repeat rate. This means the move will work as long as gravity is below (1/repeat rate)g. I've found that if you tap both rotation buttons with one continuous slide, such that you rotate on 2 successive frames, you can do the move in the example even up to speed 12. This rotates twice before the piece can fall, which gives you a 1 block height advantage. So the piece can fall 1 space before DAS kicks in and the move will still work. This allows the move to work while gravity is below (2/repeat rate)g. Did that make sense at all? What's you opinion? It would be nice if you could do some testing to compare notes before we edit the wiki further. --Colour Thief 20:38, 21 June 2006 (EDT)
This, however, is more like SRS.

 About one of the c2 kicks
I got that srs kick on tetris.com. 18.104.22.168 11:32, 15 July 2017 (PDT)
The above-mentioned kick is shown here.

 Is this an srs kick?
I did a 180 on tetris.com:
 Another peculiar tetris.com wall kick
Is this for both srs and c2, or just the latter?

180° rotation is not defined in SRS. The kick above is not in SRS.
- If you move your mouse the right way on tetris.com, you can rotate the j or l-tetrimino 180 degrees! 188.8.131.52 05:15, 30 July 2017 (PDT)
- Moving mouse is just moving to x position of mouse and predicting the orientation. Piotr Grochowski 05:53, 30 July 2017 (PDT)
NullpoMino also has SRS+ as a rotation system, but I don't know the wall kicks. Should we split this page into SRS and SRS+? 184.108.40.206 13:49, 31 July 2017 (PDT)
 Proposed srs successors
What are your proposed srs successors, and why? Be sure to include a kick table. 220.127.116.11 13:55, 8 August 2017 (PDT)
- It's because this headline exists (!) and I want to make it stand out. 18.104.22.168 05:32, 9 August 2017 (PDT)
 Other systems
I know that Piotr used to have his own system. I have my system too. I call it the Tetris Best 2 rotation system (there are 2).
What are your proposed systems? Include the following:
- Basic rotation
- Kick table(s)
22.214.171.124 09:08, 9 August 2017 (PDT)
List of proposed systems:
- Piotr's rotation system (abanonded in favor of one below)
- Tetris Best rotation system (made by Piotr Grochowski)
- Tetris rotation system (made by Piotr Grochowski)
If you want to propose a rotation system, put it in article, and this article in list.
- That's exactly what I mean! SRS should have a bunch of super kicks, that's why it's the Super Rotation System. 126.96.36.199 06:19, 26 August 2017 (PDT)
- People were dumber back in the day, so TTC only designed the rotation system with specific twists in mind, and haven't even thought about 3-kicks.
- Maybe the 2017 guideline might have it... 188.8.131.52 06:41, 26 August 2017 (PDT)
- Guideline updates are only minor. Major updates and especially overhaul should be Tetris Guideline 2.
