Work-in-progress script. I'm playing around with various designs and thoughts as I run the debugger to get information.
Included is something that tracks Link's position, gives two numbers for enemies and one number for enemy projectiles (Link's sword beams and fire shots aren't included). The numbers are damage to Link if he's hit, and how many strikes it will take to defeat an enemy at current attack power.
I also have HUD stuff at the top of the screen. Still working things out and making them pretty enough. I haven't even removed the TASEditor piece in the script, so pressing controller buttons will toggle the TASEditor stuff if that's running.
I've experimented with some registerexec and registerwrite code. One piece is enabled as of this WIP.
Finally, I have my script respond to when you press space by dumping out a list of exits and apparently related numbers. I'm not particularly inclined to disable that bit of code.
--[[  Leeland Kirwan (FatRatKnight), 2014
Allows user input to "mix" with TAS Editor using XOR logic.
If Recording is checked, this script will do its intended job.

Tap a P1 key to toggle input. If "All" is selected, will use other player keys
for related player. If an individual player is selected, uses P1 controls. You
can hold down a key to affect multiple frames, toggling the key on each frame.

For reference, Superimpose uses OR logic, and does not allow user input to
clear stored input. A great inconvience for those wishing to use the keyboard
to toggle individual input rather than mouse.
