the layout is almost correct this time and is as good as it's possible to do with  krissz 's ckit. the initial \ objects on this cave in the original game aren't in fact diamonds but diamondbirth5 objects which is the last stage of diamond birth stages (the stages which are for example used when bfly is exploded). cave b is the only cave in bd3 where diamondbirth5 is used instead of standard diamond. the visual difference of this choice is that when the opening sequence is running where the cave is revealed from a screen full of titanium walls the diamonds aren't animated but their image is stationary. this is because only real diamonds are animated and birth stages are not. this is bit silly choice by the author and i wonder if it really is intended or some kind of error. all other caves use standard diamonds as initial objects so why just cave B.. strange indeed :)

yup, i knew about that :) in cave e, falling boulders are used initially, which is more than just a visual difference there because some fireflies are pre-killed but would survive with dormant boulders. falling boulders can't be pre-set here, but i found a funny solution to this problem... ;)

that's a good point, cave e (and f?) will probably start differently here than in the bd1 engine because the boulders aren't falling boulders.  dustin , i'm curious to the solution you have in mind... ;-D

first i thought that  dustin 's solution is to replace those boulders which kill flies immediately by amoeba. but as amoeba gets scanned first it's possible that some of them will grow and escape the explosion. so i guess the solution is to put amoeba _below_ the flies which get exploded right away. that way amoeba gets no chance to grow and the explosion effect on the map is similar to initial falling boulder above the flies :)

the only problem is that if there's a fly on the bottom row and there's a falling boulder above it putting amoeba below it will put in on the border. but.. the amoeba can as well be on the right side of the fly. so the real only problem is such a fly located on the bottom right corner. then there's no safe way to explode it. but i guess  dustin  will choose a seed where there are no flies on the bottom right corner with a boulder above it :)

 nesdori , that's it! :D and the seed that logically continues the pattern of the original five seeds luckily doesn't have a fly on the bottom-right corner with boulder above it :D

however, this seed has a firefly on the bottom row with a boulder above it. it would, however, be a mistake to put an amoeba to the right of this firefly. perhaps you want to figure out how this is possible... :)

 dustin , because there's another fly which would be above the amoeba and this fly doesn't has a boulder above it so it shouldn't explode? but don't you have a big trouble then with that seed? how are you going to deal with the bottom fly?

 dustin , .. unless there's a boulder or the left border two steps to the left from the fly so that you can also place amoeba on the left side because now the amoeba can't grow to the left and escape ;)

 nesdori , it's funny - one minute after i posted this small puzzle, your solution also came to my mind as a possibility :D however, your scenario is not the case with my seed.   
here's what we have:  
  
1. a fly on the bottom row with a boulder above it  
2. placing an amoeba to the fly's right would be a mistake. placing an amoeba to the fly's left side also does not work.  
3. there is a 100% deterministic (and simple) solution.

 dustin , well there are possible set-ups for your rules:  
  
1: the boulder above the bottom fly gets exploded by another fly before it gets scanned.  
  
2: there's a fly (and a boulder above it) diagonally (up-right) to where the right-side amoeba would be. amoeba would get exloded before the bottom fly gets scanned. if also left side amoeba is not possible then the amoeba must be on the top of the bottom fly. this can be safe only if there's a boulder or diamond above that amoeba so that it can't grow upwards and escape.  
  
:)

 dustin , .. and in addition to a diamond and a boulder, on the top amoeba can also be blocked by a fly explosion which happened earlier in the scan two rows higher than where the amoeba is.

 nesdori , well, given that my rule 3 included the word "simple", it's fair to say that your solution 1 is the only possible one :D
