This shape

[Heiinz]

I just unlocked crystals and after testing around with them for a while to figure out how to integrate them in my MAM I'm pretty sure that the following shape is impossible to make:

is anybody able to mock a factory that shows how this is possible? At least second and third layer. I'm fine with the rest.

1. Create the separate NE quarter: Rr------:cy------:cy------
2. Create a shape which has SE quarter supported on the left by some arbitrary shapes. For example: ----Ru--:----Ru--:--RwRu--:--CmRu--:--cbRu--
2.1. If you are struggling with building this shape, then:
Hint 1: remember how crystals shatter when you cut them.
Hint 2: Build crcrRucr:crcrRucr:--RwRu--:--CmRu--:--cbRu-- and cut the top half. All the red crystal will disappear.
3. Rotate CW and swap these two shapes. You'll get Rr--Ru--:cy--Ru--:cyRwRu--:--CmRu--:--cbRu--
4. Now the floating part is suspended from the other side, you can cut off the temporary support. The result is one half of the requested shape: Rr------:cy------:cyRw----:--Cm----:--cb----
5. Now build the second half which is exactly the same, only rotated 180 degrees, and combine these halves with a swapper.

Ooooh. So it stays up there because the floating part is part of the first shapes crystal after the swap.

Goodness. I knew i needed to rethink my MAM but wow that complicates stuff.

Thanks alot. I'll test it now :)

Depending on your goals, supporting such shapes in MAM may not be required. The so-called TMAM (or True MAM, that can build any shape possible in the game) is a very tough task, indeed, and not many people managed to do it.

But if you only want a MAM sufficient for Random Operator Shape tasks (so called ROSMAM and CROSMAM), you don't have to make such shapes. Random shapes are very limited and will never produce shapes that require such complex procedures. The algorithm generating the tasks is known and documented on Discord. In short, it creates the shape layer by layer, with optional crystallization stage, so that if there is a crystal in the upper layers, all gaps and pins in the lower layers will also be crystallized.

[Heiinz]

So i guess i'm going for a TMAM and ultimately for a TMAM in hexagonal (i love this game).
It worked very well for pinned shapes and could be extended as far as you want. And i'm pretty proud of it so far.
One section produces one quadrant of a layer. It takes a while till it fills up but once it does it creates very complicated shapes at around 600/m.

Here is an overview:

And i already have an idea how to do the crystals and floating things, but that will take a moment to build.

Edit: And it does not wast or use global singals :D

Now let's get into the crazy portion of this.
Shape is cgcgWucg:cgcgWucg:WuWuWuWu:WuCuWuWu:WucgWuWu
why is the bottom one removing the top crystal???

[CaptainFlint]

Because with the bottom crystal broken and left side completely removed, the rest of the shape is now floating. Under gravity it drops, and whenever a shape falls down, all its crystals break.

[Heiinz]

but i cut the same portion of the shape. the top crystal just is once north and once south.

[CaptainFlint]

Since you have 3/4 of a crystal at the bottom, each time you cut the shape, that bottom crystal gets fully destroyed, leaving only 1/4 regular shape.

On the top line of your cutting line you rotate the shape in such a way, that this 1/4 remains intact after deleting the half of the shape. Here is the rotated shape:

cgWucgcg:cgWucgcg:WuWuWuWu:CuWuWuWu:cgWuWuWu

and here is what remains after you destroy the western half:

--Wu----:--Wu----:WuWu----:CuWu----:cgWu----

It's a normal supported shape, and it remains there.

However, when you destroy the western half of the original shape without rotation, you would get:

--------:--------:WuWu----:WuCu----:Wucg----

So the shape is floating in the air. In the game's physics that's impossible, such shapes always fall down to the ground under gravity. And when a shape falls down, all the crystals in that shape get destroyed, which results in:

WuWu----:WuCu----:Wu------

[Heiinz]

You are right and i'm stupid. Looks like i was thinking something different was happening.
Nvm for now, i think i got my TMAM working. (Still testing)

[Heiinz]

So it looks like the TMAM is a bit closer to a computer then i expected. But i still think i can get it to work :D

[CaptainFlint]

I haven't even started thinking about approaching a TMAM. :) On Discord I've seen a few shape examples that I have no idea how to build yet (and people said they were definitely possible). Obviously, before making a TMAM, first I'd have to know algorithms for building all possible shapes...

[Heiinz]

I ran into my hopefully last problem with this shape:
https://steamcommunity.com/sharedfiles/filedetails/?id=3413999801

I generate all 4 parts as they are supposed to be but now i need to know where the final support for the floating part is before swapping them in place. This is kind of a headache and i love it.

[Fireball]

Maybe i put this shape into my mam and see if it can do it.

[Fireball]

So i tried it (but only in 4 not 5 layers. Removed the top one, which doesn't make it easier or more complicated).
So this shape really showed a flow in my machine. Depending on where the floating corner is, I have to rotate the shape that it works, else it falls down.
But its possible with a MAM which creates each quarter first and then combining them.
