Game bugs?: Jedi Academy, gravity out

Playing multi-player online games is fun. No one else doubts that, well, no average human at least. But some people, as it happens mostly everywhere, also have fun making the experience of others the worst possible. From so-called "spawn killers" (yes, those who don't let you play even a second, throwing thermal detonators right next to you when you get "spawned" in the area) to spammers (those who should keep out of playing for a while, as announcing their new kill record gets boring for most of us) and the more-than-hated h4x0rs. Those are the real problem. Either an unfair administrator or a player with some skills and knowledge, can take advantage of specific problems inside the game engine to do all shorts of tricks.

Today's episode is about a little trick that will make most Jedi Academy players out there smile the first time they see it in action. Beware of bugs, gravity doesn't seem to affect them.

Short explanation: gravity value is used to calculate the height you can gain when jumping, the velocity needed to get back to the ground, etc. The problem is that, if gravity value changes when a player is jumping or "flying", the new constants are applied immediately. The result in this case, is first putting the player characters at the highest height and then literally crunching them into the ground.
