Yeah, this is why Quake's logic for a lot of game things - monsters, weapons, moving platforms - is written in a byte-code interpreted language (QuakeC). The idea was to separate it from the engine code so modders could easily make new games without needing access to the full engine source. (And QuakeC was supposed to be simpler as a language than C, which it... is, but at the cost of weird compromises like a single number type (float) which is also used to store bitfields by directly manipulating power of two values. Which works, of course, until your power of 2 is big enough to force the precision to drop below 1...)
