The ingame Button element at fact is Toggle. So...
Each press of TOGGLE in GUI should trigger short "click" signal
- Button switches between 2 states - 0 and 1. Which is the problem we are going to solve.
So, we will just split this signal, modify it (reverse one of them) and connect again to make consistent output.
- After click we receive endless signal. Which is another problem.
To solve it, we need to break the signal after some "click" duration. So we will add EQ-gate

You can control "click" duration by increasing amount of NOTs (=ticks) from one side

Detect if we have a task for shape or some other instance
Tips are sorted, read it one by one trying to solve by yourself
- There are 4 types of instance available:
Shape (SgSgSgSg)
Pin (P-P-P-P-)
Null (------Rw)
Crystal (cgcgcgcg)
- Null is a signal and can be checked with just Equal-check
- Only shape can be painted
- Only crystals breaks while stacking
- You can use virtual operators to check is instance changes after operation

This one can be used to trigger only on shapes*
*It will work only after shape detection (p. Crystal detector left side) which removes color.
If you don't want to virtually remove color before check, you could extend this scheme by mirroring it with any other color to prevent false detection on red
This one can be used to separate Pins and Crystals
Here is a combo of detectors with displays to understand how it works.

Create a system to store some state

Tips for 1 bit
• True(1) or False(0) is "1bit", so we need some kind of 1bit store
  
• Store is a thing which have to change output by first activation and lock it.
  
• We need some consistent source of signal(i), independent of external save/unsave
  
• We can save 1 bit (=lock signal) by opening it's gate by itself
  
• To reset bit, we have to just reset consistent signal(i)

Tips for multiple bits
• To reset memory, we need to simulate overflow, so last bit just have to reset consistent signal(i)
  
• Each bit have own output which can be used to upgrade this circuit from cumulative storage to modular switch.
  
• To make a switch, output of each bit have to block output of prev bit. So you will always get a single signal from last active bit

I've reworked it a bit - each bit has own consistent signal - so we can toggle each bit manually


3 bit memory gives us storage for 8 states. We can use it as a color selector, for example.
Also, by toggling each bit manually, we will receive color mixer.
This scheme placed under memory scheme. This is 8 combinations of OR/AND/NOT gates with labels
