bignum about swarm HOT 8 CLOSED

numbers are getting bigger, this is getting more urgent

otoh, with the inject cap coming (#65) this might become less urgent

from swarm.

this'll have to wait for the next reset. #123 makes 0.2.0's release too urgent.

hopefully the new limitations on clone (inject) keep numbers smaller this time. there's lots of other new bonuses though, and more clones are possible than before if games stretch over weeks... we'll see.

from swarm.

people are getting above 1e180 without prestige bonuses. I think prestige is going to make this more urgent.

good news: bignum wasn't too tough to get functioning. replace all js-math with math.eval().

bad news: it's unusably slow. like, with just meat/drones/larvae, I couldn't get more than 2 fps.

put the changes in their own branch for now. it'll need some profiling and optimization before it's usable - I'm sure there's some overhead to math.eval(). those are big refactorings though, and profiling is misery. it doesn't look like prestige will exceed 1e300 anyway, let's wait and see if testers agree.

took another shot at this with math.js functions and then with decimal.js. both were faster than math.eval, but still very very laggy - not promising enough to spend more time on this.

this is a priority again; it's possible to reach 1e300 legitimately and I'd rather not nerf everything

(finally) got it up to a playable speed! reworked caching everywhere; all memoize() calls are gone, replaced by a Cache class on game with fewer coarse-grained clearers (tick for counts, update for most others). a couple of tests are still upset and some template formatting is still screwy (percents) and some less visible stuff (achievements, analytics, statistics) is still busted, and the 1e300 cap is still (deliberately) in place; nothing showstopping. I now think this is doable after all.

having more types of units active makes a noticeable difference in speed: 80% idle with just drones, to 15% idle with all meat units active. same thing in prod though, so it's okay.

chrome cpu profiler is awesome. (wish I could say the same for memory, #168)

from swarm.

pushed this to publictest, at last. caught everything I could. the 1e300 limit's not yet lifted, but decimal.js is deployed on publictest for real. let's see what people break before raising the limit.

from swarm.

still a few bugs, but we're doing well enough to call this done and raise the cap. start with 1e400, raise it more later.
