Bots with 0 body? RESOLVED 2.43r

Numsgil:
I can't reproduce this, but in version p I saw a bot with 0 body floating around.  The robot console and info screen both said body -> 0.

Might be rounding.  I checked the code and I'm certain bots with body <= 0 get killed.  The bot properties dialog displays off the bot structure, but it only displays 2 digits past the decimal.  Similarly, the bot console displays the .body bot memory location, which gets rounded to an integer.   If a bot had body of say 0.003, then it would show as 0 both places...

Numsgil:
That's got to cause weird problems for the bots.  What, refbody == 0, but the bot is moving around and trying to kill me?

Maybe if body is < 1, clamp it to 1 for the robot's mem structure.  And show scientific notation if it's less than .01 in the robot info screen.

EricL:
Okey Dokey.

EricL:
Fixed in 2.43r.  I addressed this is a simple and trivial way.  At the end of the cycle, if a bot's body is < 0.5, it's dead.  Surprisingly, there was already code that did this exact thing for nrg.  It strikes me as an remedy given the integer valued mem array as this addresses refvar and nrg/body self inspection concerns without introducing funny rounding up logic that itself could potentially lead to unexpected results.
