Head on gun in melee
The reason I didn't want Neuromancer to be open source was because I wanted there to me more than one implementation style of surfing for Melee. Shadow and SilverSurfer had two very different styles of surfing, but when rozu open-sourced Apollon, everybody took that style (true-surfing) and nobody touched goto style until I came along with DrussGT. Perhaps though, by open sourcing Apollon it kickstarted the wavesurfing movement for 1v1 which may have never happened otherwise. I'll release an open version of current Neuromancer in a few weeks, that will give me some motivation to get these features added =)
It is quite possible to get a fast Play It Forward - the gun in Neuromancer depends on it.
And I think you may be disappointed with how simple Neuromancer is =) I suspect those who read through it will go "Oh, obviously." and proceed to write their own equivalent from scratch, much like others have done with the BasicSurfer.
Well, I am looking forward to get my "Aha" moment. I you kept us in suspense for long enough :) Who knows, may be someone will use it as a spring board to beat the king.
I was trying to avoid PIF, since I would have to redo a lot of code. But deep inside, I believe PIF is more physical than GF targeting. I tend to agree with Voidious that Displacement Vectors in melee make more sense. PIF seems to be a gun which would be in alignment with this idea.
I like PIF for melee because it means I don't have to make assumptions that bots are moving relative to me, or their nearest enemy. I find in melee multiple enemies and walls can all affect movement, so the assumptions for GF and displacement vectors don't necessarily hold true. Of course, they are much faster.
