Level Creation Megathread

[CVTesttube]

(My earlier levels, for organization)

I've made some new levels (most before 0.4)

How does one get those odd homing guns and metal and bomb blocks, and red fields in the level?

So I made a level: Sign Wave

Here's a cool mechanism, not really a difficult level. Adjust the red, green, and blue switches, wait a bit, then pull the yellow switch and wait. The level wasn't intended to be playable/beatable, but I added some little tricks so it was.

The pattern of bomb-blocks turns into the letter corresponding to the binary number, and X if 0.

Why are there 6 stars? Can you get them all?

This is why you shouldn't restrict us to only 3 stars in a level (http://testtubegames.com/forums/viewtop ... 3042#p3042). This is a very trivial configuration, though. It's possible to make earlier choices in a level affect which minigame/puzzles you have to do.

How does the mechanism work?

SPOILER

SPOILER_SHOW

It's mostly self-explanatory. First note that the display has exactly one block per row, so the 15 missiles on the left can each choose whether or not to hit them. We want to block the missiles from hitting the dots that need to be "on". This can be done with a column of blocks, but we can't individually switch a specific column on or off - That would be too expensive switch-wise (and would require 8, which is impossible right now).
What we do instead is make a selector to choose which blocks to keep (note that bomb blocks also work, since the missiles only fire once), and erase the other ones. However, binary selectors are AND gates exclusively - they'd only destroy one column, instead of keep one*. So we invert the signals from the selector, keeping the selected bomb-column.
Once the clearing is done, we "pulse" the missiles once to read the stored information onto the display.

*I wonder if you could avoid the inverter by counting forward 6 steps in binary or something. It seems it might work, but why would anyone do that? It'd be ridiculously slow.

So, Since the binary only goes 0-7, and you put in XABCDEFG, how could you represent the other 19? (HIJKLMNOPQRSTUVWYZ)
