Forget the scripting thing.
If you learn it normal, you will be more versitile. I see what your askin', and hope I can help more then the rest of these poor peeps.
I keep it on the middle button, for quick access, of course fire on left, and alt on right.
- Practice to get used to it's arc and distance.
- Never stand still and watch the disc.
- Know how to quickly get to a weapon upon telleporting, or canceling.
- Never leave discs laying around.
- Never try to retrieve a broke disc (I still do this all the time).
- Know you can pick up a broke disc by walkin' over it.
- Don't "telletain" w/ quick telleports.
If you fire a disc up at 30degrees or so, and telleport to it right before it hits the ground, you will get the max speed out of it.
If you're looking to move more on the Y axis, aim, and mapknowledge will play a huge part. Knowing what you can reach, w/ or w/o a jump, and when you can or can't double TL jump.
Also note that when you jump, or dodge, you momentum is carried into the disc similar to a lift jump.
With TF's (my personal favorite) timing is everything. It's most effective (of couse) as a quick way to kill a still target you've snuck up on. Practice that first, 'casue it takes speed to get to it, use it, and go back, and once you've done well there, the rest will come. Another good way to practice is play a botmach on a map you know well, and start the bots on novice, make them adapt, and only use the loc. If you can consistantly TF skilled or experienced bots, you doin' all right.
As far as how you get back to a good weapon, I live and die by the switchtobestweapon button. I don't use autoswitch (got screwed out of too many hammer kills there), and reflexively now hit the Best Weapon button every time I walk over a gun (even if the best is in hand).
Having a quick weapon as your best weapong helps with that, ie: Sniper Rifle, SR, or Minigun. You can do OK w/ the RL, but flak is too slow to load, out of the question. Actully, even the Minigun is a lil slow to wind up, and anything else prolly wouldn't top your priorities.
The key thing is know it's behavior, it's just like getting used to the arc of a flak bomb. It just takes some..,, (gasp!) practice!
---More advanced Strategy's---
Try not to think very 2 dimentionally with it. It can be used as a great dodging tool. It moves in directions faster then you can dodge, and it can slip in through narrow places you don't fit (like between or over multi rockets). I can make it appear I walk straight through on coming rockets, by telleporting behind them as they come at me (always impresses my friends).
Many holes it will fit into, can get you places faster as well, like the long flat window on agony, and that is all about aim. It's also good to think about going up through holes you usually fall though, like so many places on curse. Of course elevations is the obvious one, but I'm sure you see what I'm saying.
I also love using it to get behind opponents, but this will come after you get the weapon switching speed thing down.
Something else to think about (my signature move), is maybe try sometimes using a telleport to get you out of a corner instead of into one. If you need a weapon that's in a rough spot, like the top RL in deck, Chuck the disc out somewhere, like towards the ripper, get the RL, and telleport out, avoiding combos. Another good one is the belt/amp on pressure. Telleport out to avoid being depressureized.
I know it's a lot, but it should be helpful My apologies if some of this stuff is more or less common knowledge.
-Side note-
My TL was my 3rd most fragged w/ weapon when I rated. I used it soo much I had 2 suicides with it.... don't ask...
