Suspension subclassing; CARSUSPENSIONINFO struct.

[fudje]

On the subject, I've been thinking on how to implement codepedent suspension, and my current theory is the best option goes in configuration with something like:

Code:

[suspensionlink/rear]
# Funky link frame parameters go here

[wheel/rl]
suspension = linked
suspensionlink = rear
# Wheel specific parameters

[wheel/rr]
suspension = linked
suspensionlink = rear
# Wheel specific parameters

Codewise, the suspension links themselves could be stored for loading purposes in a string map that is initially empty, the first wheel to look up a mapping creates it, every subsequent look up will reference the same map — during the actual simulation each wheel position refers to its relevant link directly, avoiding the STL overhead. The caveat is that CARDYNAMICS Load routine would need to know a little about linked suspension (at the least provide a map), but I guess that's not so bad. Additionally all wheels linked together would need to update their positions before force is applied to any of them.
