So I know if you set the car engines 500hp or more it would accelerate and move at f*ck per hour, you can set the max speed using the max angular velocity,
But the acceleration is too fast, now my question is, how can I slow the acceleration without changing the torque on the engine, because if you set the min-max to 0.2+ it would lose torque.
Engines naturally have more acceleration at low speeds. You can multiply the input by the inverse of speed for a constant power
The way I was taught was with a gforce limit. It works well. X is your g force. Anything above 1.025 i recommend. For my 55 chevy that's what I have it set to, but something with more hp i go to 1.075, 1.1
GForce >= x ? 0 : clamp01(Pitch)
now you mentioned it, i dont know how to limit acceleration rate
lol i hope i could help, but the acceleration rate isnt really a concern to me
