You can't (or rather shouldn't) change DataBlock values during runtime, but you can use setMoveSpeed instead. Have the maxForwardSpeed set to something high like 20 or so, then when the AIPlayer is spawned just reduce the speed with %bot.setMoveSpeed(0.5). Then when the AIPlayer is in the air set it back to max with %bot.setMoveSpeed(1).I was wondering, can maxForwardSpeed be changed "on the fly" via script? I noticed the higher my maxForwardSpeed was set, the more "air control" I had. If I could set maxForwardSpeed to a higher variable upon using the "mJetting" trigger via script, it would solve my "air control" issues.
