I was wondering if anyone knew of techniques to assist with several things?

1. No Save : I want to allow the PC to only Save in certain Places, in a Certain manner-- anyone have any ideas?

2. After Effects : I'd like to put in an Aftereffect when the Player Runs, Jumps or uses Dash -- what I am thinking is kind of like Alucard had in Symphony of the Night, or Hyper Sonic had in Sonic and Knuckles: another "version" of the character following the exact same path, at the same speed, but a few hundeths of a second behind...

3. Double Jump : Any way to do a double jump? I thought of using another item underneath the player, but it did not work... So any ideas on this owuld be great. Using a direct SetPos Z works, but looks messy and not very good for what I was hoping (such as being able to alter direction in mid-air)

Thanks for any comments
