But you seem to understand the issue. I am doing linetrace a car, an SUV. The collision consists of two primitives of spheres, and, as it should be, the center of mass is shifted downward to increase stability, but during jumps and hits, I would like to avoid any rotation at all, and the suspension force works constantly and the car, for example, when driving into a wall does not must rotate, and must maintain direction.
In general, all physics is quite simple, no gearbox, no complex friction model, very arcade physics. Is it possible to simulate the suspension forces using only math, without resorting to built-in physics?
