Constant friction force

[Kilinich]

It can be very useful for top view games like pool.
It's a script for circles with constant air friction (works with any custom air).

force (in Newtons) is adjusted via _frictionForce variable

Code: Select all

_frictionForce = 1;
airFrictionMult = {
    circle := readable(owner);
    v := circle.vel;
    u2 := (v(0) * v(0) + v(1) * v(1));
    u := u2 ^ 0.50000000;
    d := circle.radius * 2;
    ff := d * (Sim.airFrictionLinear * u + Sim.airFrictionQuadratic * u2);
    ff == 0 ? 1 : {owner._frictionForce / ff / Sim.airFrictionMultiplier}
}


Just put that code into circle's script window and it will behave like a hockey puck

Great for top view car sims too.
