I'll leave the cameras to someone else, as my vector maths is terrible.
And the hang I havent any idea on, I think its a big bit beyond the scope of this script.
But, here is some code to get the double-jump in, splice it in at around line 250 in PLAYER.c The the abs(my.velocity_z) <= 10 is the number to play with to set the time the double jump is available. Its currently set to about the top 20% of the jump. So double jump wont react unless you hit space when you are 'almost' at the top, or just starting to come back down. It doesnt react at all to falling from a height.
I know this post is kind of old but I wanted to share this little extra because I think it's pretty cool.
I added mickey.z zoom in and out and also converted an old if comparison for alpha fade on the character. When you zoom in or if the camera collides with a wall and comes close to the character the character will become translucent. Also added two wait(1)'s to handle_sword_collision and handle_hand_collision. There seemed to be a Crash to desktop if you clicked the mouse to many times and from what I can tell the wait()'s seem to be helping.
I did not put alpha fade on the sword because it just seems really cool to me to be able to still see the sword while zoomed in. I hope someone finds this useful, cheers...
Alpha fade between lines: 331 and 351 wait(1) at line: 413 and 432
