decreasing gravity in udk?

I am trying to create a mod in udk by adding jetpacks, so I need the players to jump v开发者_开发技巧ery high, I can't figure out how to do this in unreal script. Can someone explain how to do this or point me to a good tutorial. thanks

If you're just trying to change the jump height I would recommend changing the Pawn's JumpZ instead of changing the gravity on the whole map. Vehicles floating off may be fun for a moment, but it can mess up gameplay. If you change JumpZ you might also want to change the fall damage, so you don't die just from jumping.

You can start by taking a look at the code for the low gravity mutator that is present in Unreal Tournament 2004.
