Tetris... in Factorio?

[XKnight]

Unfortunately rotation was not implemented, because I am tired and this challenge a little bit boring.
But maybe I will come back to this task tomorrow

I decided to start working on the improved version, main goals:
- add rotation
- simplify collision check
- simplify L/R move
- reduce cycle length below 15 ticks at least
- increase interface responsiveness

That looks cool. How do you store the game state?

1.png

Simple 2D array with 0/1 in each cell:

0 1 0 0 1 1
0 1 0 1 1 0
0 1 1 1 1 0
0 0 1 1 1 1
0 1 1 0 0 0

Each column can be represented as a single number:

0 1 0 0 1 1 | 16|
0 1 0 1 1 0 | _8|
0 1 1 1 1 0 | _4| => 0 29 7 14 30 18
0 0 1 1 1 1 | _2|
0 1 1 0 0 0 | _1|

Each number is stored as a unique signal
0 29 7 14 30 18 => "A" 0, "B" 29, "C" 7, "D" 14, "E" 30, "F" 18

As a result you can store 2D array with dimensions 180 x 32 inside one combinator.

Second combinator is used to store falling object.

Cool, that is the reason there are 30 rows I guess (2^31 is the limit of the cominator numbers).

I'm quite surprised, that the setup is not too big, making this using redstone would probably be a lot bigger.

Is the map accessible?

It would be good to have some kind of button + switch entities to play with these kind of things, I'm not sure if we have it in the roadmap for 0.13, but it would be really easy to do.

Is the map accessible?

Sorry, but I can not share the whole map, because it contains several other unique contraptions...
But you can find blueprint string for tetris here: http://factorioblueprints.com/view/hYvDtGfpLg8MjmYaS

You should put 1 green circuit into the "Interface chest" to move figure left, 1 red circuit - to move right.
To erase map you should rebuild "Map" combinator.

Just a small hint: you can place red/greed circuits on your quickbar (under the key "1" and "2"), and do not close chest window while playing.

Blimey. I am filled with speechless amazement.

Wow!

I am building a 7-color display, so I need 200 unique color signals. (Because colored lamps require a color signal.)

That means every lamp needs its own wire and decoder. Here is the board before it is wired up. This is going to be like my days in IT wiring a patch panel.

I am optimizing for speed, which means massively parallel circuit design. Each of the 200 lamps has its own memory cell. Each memory cell has 11 built-in functions with direct memory access.

I'm a bit worried this will drop Factorio below 60 FPS.

[piriform]

Not sure if I've got this right
200 cells@ 65 tiles/ cell + ~500 for the display ~13500/1024 =13+ chunks = EPIC!

The main problem is getting player input, it is quite awkward without mods.

It would be good to have some kind of button + switch entities to play with these kind of things, I'm not sure if we have it in the roadmap for 0.13, but it would be really easy to do.

You should put 1 green circuit into the "Interface chest" to move figure left, 1 red circuit - to move right.
To erase map you should rebuild "Map" combinator.

This sort of situation is the exact reason I made the pressure plates mod. Using three pressure plates to control the left, right, and rotate functions would be a lot easier than placing things into a chest. I would be super happy if my mod could help make such a great build possible.

The bottom line for this week FFF is clear now.

I decided to start working on the improved version, main goals:
- add rotation
- simplify collision check
- simplify L/R move
- reduce cycle length below 15 ticks at least
- increase interface responsiveness

Finally I found some time to finish this Tetris...

- removed global clock generator. This is the most significant improvement, because using GCG always means dirty and slow solution, but this solution can be implemented very fast. As a result, new main cycle has variable length (6 or 7 ticks) and it is about 3 times faster than previous build (20 ticks). I even had to put 3 smart inserters more, because one smart insert is not capable to handle new speed.
- lots of things were simplified: previous build used 150 combinators, new one - 125.
- added possibility to rotate object.
- added possibility to perform several rotation/moves per one fall (by default 4 moves).
- added possibility to temporary increase falling speed (x5).

Known issues: slow filled line processing (due to incompatibility with new data representation); may be improved in future.
Also wall kicks (from original tetris) may be easily added, the only missed thing is an array with predefined offsets.

Awesome!

[piriform]

Very nice work!
So what's next? Pacman or Space Invaders?

[Fish]

Wow, nice job!

[Koub]

[Koub] Topic moved to "Show your creations" upon a member's suggestion . Surely this is a creation that deserves to be shown.

[Smarty]

Very nice work!

Factorio

Wait what?

factorio in factorio?

[Koub]

I've seen game of life playing game of life. It's the most amazing thing I've ever seen, so much Inception-like .
Admit it : Factorio playing Factorio would be totally mind blowing - even if I'm aware it can't be done ^^

Strange, I can't do the opposite. I always play Factorio while playing Factorio. And it's totally mindblowing indeed.

Awesomesauce Tetries by the way.

The perils of including a turing complete system within your game

Perils, what perils? If that's the worst that can happen, then bring it on. I'm almost certain that the Laundry Files scenario is just fiction and could never happen in RL or Factorio..... I think

[zytukin]

need some way to play notes now so you can add the classic tetris music
