JumpDrives
I've come up with several ideas on how this could work, and it mostly relies upon whether or not jumping is coded to the engine or if it can be added to an item at all. One method would be to set a "jump point" in a sector, and when the JumpDrive ability is activated, either through the after-burner key, or through a new command to keymap under options. When activated the JumpDrive would do a jumpgate style warp from the ship's location to the jump point.
Another possibility, although a bit harder to implement I would think, would be to allow the ship to jump to any sector it's already visited, via the galaxy navmap. This would seem impossible with what I current know.
Any infomation you guys can add would be invaulable, as you've all helped me greatly in the mod I'm making for my private universe. Thanks again.
