hmm lets see. here are some I can think of off the top of my head
Additive Jump-Velocity
Similarly to jump jetting, any events/script that addVelocity to the player (i.e onPlayerTouch player addVelocity 0 0 10) will have increased effect if you press jump upon touching said brick/object
Crouch Humping
Make sure you have sit function bound to a shortcut key. Hold shift and jump, then while in the air use sit and press S/move backwards at the same time, you will be stuck in the crouchBack sequence.
I could never figure out how to use addVelocity correctly, instead I always just used setVelocity for sending people skywards. Does addVelocity only work if people are already moving?
As for the crouch humping, I'm pretty sure I had to learn that technique when I was playing Badspot in L's blockland researcho.
