HOW DO BUMPSTOPS WORK?
Bumpstops are an extra spring in the suspension system that deal with the highest compression area. They are available since v0.6.3.
To add bumpstops, you add 2 variables to your car.ini's susp<x> sections:
The bumpstop is a non-linear spring, meaning its spring rate increases with compression. So the force itself will increase exponentially. The bumpstop will kick in when spring length = min_len+bumpstop_len. At that point the force is just 0. Once the spring length reaches min_len it uses its full rate (bumpstop_k).
Currently the bumpstop spring rate is linearly calculated from its compression.
TESTING THE BUMPSTOP
When designing the car's physics, set gfx.show_car_points to 1 (in racer.ini). It will show the suspension attachment point, plus the suspension line and also the bumpstop start as a yellow dot.
