[Help] Missile proportional navigation

Hello!

I'm into investigating some still unclear stuff on BF2, that is PR modding, and this time it's missiles. I need help because I've been trying to do this in past few days without success. As I'd like the new PR 1.0 to be as much as real as possible, I think this would add much to realism.

I'd like to recreate real life missile's proportional navigation. It is set of algorithms that missile guidance section uses to navigate itself to target, to intercept it instead to follow its tail. All modern missiles use this, and you can sometimes see it going towards aircraft without even changing course, because it predicts aircraft movement.

I've tried several things, one of them was placing heat_object infront of aircraft which was too complicated and didn't work well. I also tried adding objecttemplate.follow.predictionfactor, but I realised it only works with older BF versions (BF2142 or w/e).

So, does someone know or has idea how this could be done. I think it would look much better, because only games like MW2 still have this, and ARMA2 has it like suggested here. So if someone has some kind of idea, let me know.

Is there a way that a command which is probably implemented into engine to be kind of "unlocked" for BF2 as well? (objecttemplate.follow.predictionfactor) It works with BF2142, and it should with this one.

I'd be willing to make if perfect and suggest it to DEVs.

Thanks,
