73 Rats multiply and exterminate first a single city and then all mankind. Increased size and intelligence.

Like Katamari Damacy but horrible. Drive your swarm of rats around a city and eat people.



Rat sprite:


Unlikely that I will actually finish/seriously attempt to finish this... but might as well clutter up the forum anyway.

UPDATE 19/10/08:
Made quick, dirty prototype:

Second prototype, with human eating:

I love it. You'd better release something.

Fuck rat kings so so goddamn creepy!

Another tmnt game sweet.

Prototype of rat swarming. Played with a bunch of different methods, none of which I was very happy with. This method is pretty simple -- the rats just chase after the mouse, but can't get too close to each other:

Click to add more rats. Please let me know how many rats it takes to make the framerate drop, so I can balance for people's setups. My year-old iMac can happily handle up to 175-200 rats, so I figure I'll keep the maximum around there.

~150.

My computer started to lag at around 215, and it went rapidly downhill from there.

Right now the rats look kind of uniform, not so much a swarm as a regimented army. If you could add a bit of randomness, say in how fast they walk or how far apart they stand, then it would probably look better. Still, it's already quite a fun prototype to mess around with. Just like the prototype of Buddy Base II. What's with that?

Oh, and the swarm kind of screws up if you drop lots of rats in the middle of it, but I'm guessing that won't be an issue in the final product because you can't just make rats whenever you feel like it...?

Started rapidly crapping out at around 180. Let me try it once more with Flash 10 installed (still using 9)
edit: Oddly enough it crapped out SOONER using Flash 10, at around 170. This suggests to me that the problem many not necessarily be with having too many rats, but possibly a bug that gets more likely to happen and slow things down the more rats are on the screen. Maybe something to look into.

I'm on my crappy(er) computer right now and the fps starts to dip into the 20's at around seventy rats.

I can give a number from my better computer later (this one's mainly just for browsing).

Nice prototype though.  I like the almost gooey feel of the rat-blob.  I agree it could use a little more randomness from individual rats.  Like some of could maybe be not as "in tune" with the rest of the swarm and might take a second or so to realize that everyone's going that way now, or maybe when the swarm is at rest a couple might just sort of wander around in the general area of the swarm.

First issues at 190 Rats, but still perfectly playable. Occasional dips to 28 fps.

Occasional problems at 210 Rats, but continues to be responsive. Constantly in the 20's.

Exponential decay from then on. 222 Rats ~4 fps.

I'm getting around 100 - 120 rats before fps starts to fall (rapidly). It looks really cool with a lot of rats but as mentioned earlier it also looks a bit static. Maybe look into boids (not the best looking version bu you get the idea) to get more natural moving rat packs?

[policedanceclub]

ha ha, i love it already!
the way the rats move feels good.


anyway, it started to slow down at around 220 rats, and finally became unplayable at around 250.

[narasu]

slowed down at 180, became unplayable at 190

[awesty]

Frame rate dropped below 30 at 320 rates 

[increpare]

from about 220 it occasionally dips below twenty, but only does so for extended periods at 250.
