Formation algorithem


#1

I have noticed that ships under the formation order tend to lag behind the formation leader. I am guessing that the current algorithm dictates that ships under the formation command want to move to the location relative to the formation leader with a certain fudge factor. I can guess that without the fudge factor ships would overshoot their formation station and loop around thus falling further behind the leader.

Instead of setting the destination location for a ship relative to the formation leader’s current position, how about you set it relative to the formation leader’s future position as calculated by the current position + speed vector * arbitrary length of time. This solution works for Boids (red3d.com/cwr/boids/) and I hope it will work here.

The lead ship may also want to adjust its speed to help with proper alignment, which would also help faster ships with their habit of leaving a following formation in the dust.
