How defrag tricks work

Postby <hk> » Dec 5th, '10, 2:53 am

This thread is about defrag engine bugs/features people abuse to get faster times. How they work in detail should be explained somewhere, though. This is the place.

Let's make a list of all Quake3/Defrag Bugs that are out there and try to explain them together. So it's mainly a thread about programming or math.

Incomplete list:
  • Strafejumping
  • Airstrafe [thread]
  • Skimming
  • Overbouncing
  • Sticky Overbounces (somehow not the same)
  • Groundboosting [thread]
  • TeleJumping (pretty much like groundboosting)
  • Wallstrafing
  • Rebouncing (being stuck in a wall accumulating speed (used in sjt2))
  • Z-Rebouncing (the trick solving think17)
  • Edgesliding
  • Ramping

Some of these Items are actually the same. I just took everything that came to mind and threw it in.
I made that "Z-Rebouncing" up, because I don't know the real name or it's origin in the code. To my knowledge nobody named it yet. Same goes for "Edgesliding".
