Laser limits
In my testing on the vanilla puzzlemaker i think ive found a soft limit. When building my latest puzzle i was using laser cubes stored behind glass panels to align lasers to their destinations, and found that after a certain number of lasers were present in the level editor, the cubes stopped working. I assume this is related to how cubes can "go to sleep" and when there are enough lasers to track, the game fails to register a static cube being hit with a laser and to then send the laser onward.

However it actually works, it would appear that 25 lasers are the maximum, at least in my testing, that a level can have before this bug starts to appear. luckily thats exactly the number you need to run 4 memory cells, 4 exclusion gates, a sequencer, and 4 lasers for the actual test to use.

BASE 4 IS VIABLE :steamhappy:

also the "ratman" room i hid in this level contains an exposed version of the circuitry. there is a portalable surface behind a grate in the top left corner if you want to see how it functions. just press the pedestal button to begin the test. (i didnt have enough level memory left to put in a self start on this one)

apon futher testing ive found the actual laser limit to be set at 30. this is a hard cap, and counts the number of active laser cubes into this value.

this means that if you have a test which has 29 laser emitters built into it however, you can gain access to an interesting mechanic. artificially limited beams. with 29 static laser emitters, even if switched off and hidden, your player will only ever be able to have a single laser cube active at a time. this allows you to give the player multiple laser cubes without them being able to use them to solve problems in the obvious way.

Another even better application of this bug is the ability to lock a cube into an active state permanently. If the chain of lasers is arranged so that the 30th beam is a cube pointing to another cube, that cube will become permanently active even when removed from the chain. this opens the vanilla map maker up to making run and gun style levels, or interesting permutations of momentum courses where the active laser cube being taken thru the level with you becomes the difficulty.
