[RELEASE] Hub
Eh... what?
Sorry, never mind. Just ignore that.

Turrets holding down buttons are in Portal, but only in Test Chamber 16 tho. . .
I think if its necessary turrets should hold buttons down.
The more you give, the less appreciated it will be received.
That's certainly more consistent with the main game. Although personally I don't mind if map designers choose to "bend the rules" a little in this regard, if it results in a more interesting puzzle. You can always find out what pushes down a button by experimenting. (For example in Affinity, there are two buttons that only work with cubes.) Although it would be nice to provide some signage or other visual clue for things that are different from the main game.
BTW, I have another question about the map: How do the panels with indicator lights rotate to a different starting position every time a new game is started? Is there some way to place obects randomly in the game? And how does it know when two panels are lined up correctly?

Hmm, I don't mind if turrets can press down buttons, but it wouldn't be my first solution if play a new map. In Hub however, the buttons were not meant to be pressed down by the turrets.
The randomness: With the PickRandom input, I let a logic_case choose a panel to rotate. This is done four times.
The connected indicators: This took me many frustrating hours. If I just could have programmed it in C++ it would have taken minutes. Anyway... Each panel has a math_counter and a logic_relay. The math_counter knows in which direction the panel is facing. The logic_relay triggers the desired outputs when the indicators of its panel is connected.
Each time a level of panels is rotating, 1 is added to the counter of each panel on that level. The math_counters restart when the panels have rotated one revolution. When a math_counter reaches it's maximum value, its panel is facing forward. The OnHitMax ouput will then enable the logic_relay of the panel and disable all the other logic_relays on that level.
When a level of panels has finished rotating, a logic_relay will try to trigger all the logic_relays of the bottom level. Only the logic_relay enabled by its math_counter will take the input. The others are disabled and will ignore it.
The logic_relay activated on the bottom level will then try to activate the logic_relay of the panel(s) that can be connected on the second level. If the logic_relay on the second is enabled and can be connected, it will try to trigger the third level and so on. If it is disbled, the connection has failed and the indicator will remain blue.
Example: Panel 1A, 2A and 3C are the ones facing forward. A level of panels has just been rotated. A logic_relay will therefore try to trigger the logic_relays of panel 1A, 1B and 1C. The 1A math_counter has reached its maximum value and will therefore have enabled logic_relay 1A and disabled 1B and 1C. The logic_relay 1A will therefore take the input and turn the indicator orange, open the doors of the room on the second floor and so on. It will also try to trigger logic_relay 2A. Because 2A is facing forward, and is therefore enabled, it will accept the trigger input from 1A and do its stuff. 2A will then try to activate 3A, but 3A is disabled because 3C is the one facing forward. The chain of outputs has ended and the player needs to rotate the third level to continue up.
Hope that makes sense

Nice. I'll study it closer when I get time.
Very smart! Your set-up is very much like actual electrical connections are being made between the panels. I can imagine that it took a long time to come up with that idea.

Impressive. I don't have the patience for pushing those damn boxes around. My first run through only took me 154 portals. I've managed to get it down to 48 though.
thanks!
getting one of the boxes to fall over the edge just enough so that it is vertical is quite irritating... i had to push really slowly and at and angle so it didnt just tumble all the way down the stairs...
