Box-Wing

[Kilinich]

Now simplest wing ever:

for box:

Code: Select all

_airForceMult := 0.05;
airFrictionMult = { v := entity.vel;
    n := [ - math.sin(entity.angle), math.cos(entity.angle)];
    vn := ((v(0) * n(0) + v(1) * n(1)));
    entity.vel = entity.vel - n * vn * entity._airForceMult;
    0}

and for airplanes is more realistic code with quadratic force part:

Code: Select all

_airForceMult := 0.1;
_airForceMult2 := 0.01;
airFrictionMult = {v := entity.vel;
    n := [ - math.sin(entity.angle), math.cos(entity.angle)];
    vn := ((v(0) * n(0) + v(1) * n(1)));
    v1 := n * vn * entity._airForceMult;
    v2 := n * vn * vn * entity._airForceMult2;
    entity.vel = entity.vel - v1 - (vn > 0 ? v2 :  - v2);
    0
}
