Firing perfectly forward gives the highest inheritance, but firing at an angle gives lower inheritance. If you're mathematically inclined, here's a precise description of the idea. Consider the moment at which a player fires a projectile. Let u be the player velocity, v be the naive projectile velocity, x be the angle between u and v, and m and M be constants with 0 <= m <= M <= 1. m to M cosine inheritance sets the final projectile velocity to v + (m + max(cos(x), 0)(M - m))u. Flat inheritance means m = M. The holy grail is m = M = 1.

Re: please address the many CORE PHYSICS ISSUES ASAP

Someone go back to page 1 look at all the complaints, Count how many problems have been fixed and how many are still complaints. I think it's 80/20%, That's not in there favor. I could be wrong.

This is without a doubt the egg on Hi-Rez's face. And I don't know if they know how to fix it.

Re: please address the many CORE PHYSICS ISSUES ASAP

I did some testing on grenades. The following still use the old fish patch 0% to 100% cosine inheritance. The rest use flat inheritance.

Brute Fractal Grenade
Brute Light Sticky Grenade
Doombringer Frag Grenade
Infiltrator Sticky Grenade
Juggernaut Heavy AP Grenade
Raider EMP Grenade
Raider Whiteout Grenade
Sentinel T5 Grenade
Soldier Anti Personnel Grenade
Soldier Frag Grenade XL
Soldier Proximity Grenade
Technician TCNG

If you're not familiar with cosine inheritance, it means that the amount of inheritance depends on the angle between your firing direction and your motion direction. Firing perfectly forward gives the highest inheritance, but firing at an angle gives lower inheritance.

If you're mathematically inclined, here's a precise description of the idea. Consider the moment at which a player fires a projectile. Let u be the player velocity, v be the naive projectile velocity, x be the angle between u and v, and m and M be constants with 0 <= m <= M <= 1. m to M cosine inheritance sets the final projectile velocity to v + (m + max(cos(x), 0)(M - m))u. Flat inheritance means m = M. The holy grail is m = M = 1.
