The entity getters I'm referring to are entityclass::getscm(), entityclass::getlineat(), entityclass::getcrewman(), and entityclass::getcustomcrewman(). Even though the player should always exist, and the player should always be indice 0, I wouldn't want to make that assumption. I've been wrong before. Also, these functions returning 0 lull you into a false sense of security. If you assume that commands using these functions are fine, you'll forget about the fact that `i` in those commands could be potentially anything, given an invalid argument. In fact, it's possible to index createactivityzone(), flipgravity(), and customposition() out-of-bounds by setting `i` to anything! Well, WAS possible. I fixed it so now they can't. Furthermore, in the game.scmmoveme block in gamelogic(), obj.getplayer() wasn't even checked, even though it's been checked in all other places. I only caught it just now because I wanted to bounds-check all usages of obj.getscm(), too, and that game.scmmove block also used obj.getscm() without bounds-checking it as well.
