spider and dragon eaters

Post by lifespeed » December 23rd, 2010, 1:02 pm

I think that an eater for spider is possible though the following reaction

Code: Select all

x = 59, y = 20, rule = B3/S23
5bobo43bobo$6b2o43b2o$6bo45bo$obo53bobo$b2o53b2o$bo55bo3$21bo15bo$22bo

detection could be achieved though it's spark

a similar thing could be done with dragon as

Code: Select all

x = 42, y = 38, rule = B3/S23

Well, of course it would be possible, but it's not really feasible because of the size and long recovery time required.

Maybe not so big or long lasting as initially thought (although it's only a partial):

Code: Select all

x = 32, y = 65, rule = B3/S23
4b2o20b2o$5bo6b2o4b2o6bo$5bobo4b2o4b2o4bobo$6b2o16b2o8$2o28b2o$bo28bo$

This deletes two blocks instead:

Code: Select all

x = 26, y = 65, rule = B3/S23

3o6b3o3$7b3o6b3o$6b5o4b5o$5bo5bo2bo5bo$6bo3bo4bo3bo!
This one's nice and reactive; perhaps something could be made out of it:

Code: Select all

x = 20, y = 34, rule = B3/S23
4b2o5b2o$4b2o5b2o3$4bo6bo$2b2ob2o2b2ob2o4$2b2ob2o2b2ob2o$2b2o2bo2bo2b

Killing those honeyfarms isn't a problem…

Code: Select all

x = 32, y = 35, rule = life

…but those two blocks that the trailing part tends to turn to are a bit pesky indeed.

As for spider, a simple pair of blocks kind of works (they end up shifted 3 cells towards the spider):

Code: Select all

x = 27, y = 14, rule = B3/S23
9b2o5b2o$9b2o5b2o5$2b2o5b2o5b2o5b2o$o3bo3bo2bo3bo2bo3bo3bo$o3bobob3o5b

15bo2bo!
Edit: Almost got dragon. This leaves just a single barge at the edge of the pattern, but all standard eaters seem to do is to reduce it to a boat at best.

Code: Select all

x = 30, y = 45, rule = life
17bo$o14b3o$3o11bo$3bo10b2o$2b2o9$25bo$24bobo$5bo6bo11bobo$3b2ob2o2b2o

o3b2o3bo$3b3o6b3o3$3b3o6b3o$2b5o4b5o$bo5bo2bo5bo$2bo3bo4bo3bo!
…And two further approaches that are looking promising to some degree.

Code: Select all

x = 96, y = 45, rule = life

Almost got dragon:
