Head-Fake Targeting

Quick and Dirty

The fast way to code it.

Take any targeting method you already have (other than Head-On Targeting) and find the predicted difference in angle from dead-on. Shoot at the opposite angle (compared to dead-on). (e.g. your opponent is at 15 degrees, your circular targeting says to fire at +20 degrees, you fire at 355 degrees.)

Realistic

The proper way to code it.

Create a new targeting method based on any targeting method you already have (other than Head-On Targeting). Assume your opponent will accelerate at top speed in the opposite direction. Extrapolate his position until you have an acceptable firing solution.
