Speedhacking is way to easy in this game ... i used it in stealth on my Scoundrel to farm on ilum
Using CE:
1. Autorun in a corner, search for float 0.6
2. Stop running
3. search for 0.0
4. Repeat first 3 steps
5. optional use the runspeed buff and search for 0.81, or when you have stealth search for 0.51 (while running)
It should leave ya with 2 addresses, pick the topmost.
Now, you can change and freeze this address and it will work ... but clumsy and it stutters because SWTOR tries to overwrite.
If you search for "what writes to this address", you should find only one line. Dissassemble it and NOP it ( make it do nothing).
There ya go, have fun, use it smartly.
