I have been thinking about some sort of properly implemented stability control system for some time now. A while ago I had a very rough prototype working for the sunburst but it did not respect the steering angle at all so I will start again from scratch and will try to make it a bit more sophisticated. For those that are unaware of how such a system works in real life, here's a quick rundown: Detect the desired handling Detect the actual handling Calculate the difference between desired and actual Apply breaking torque to specific wheels based on the difference Actually quite a simple idea in it's most basic form, however implementing such a system is a totally different animal. To achieve this, you need access to several things: Something to measure the desired handling --> Steering angle (the drivers wants the car to go where the front wheels point) Something to measure the actual handling --> A Yaw sensor which indicates the car's rotation + slip sensors for the wheels As you can see, most stuff is already there however, I am struggling with the Yaw at this point. Is there any way to get the yaw momentum from the current car (in a somewhat quickly updated way)? On another note: How often are the updateGFX methods from vehicle LUA files called per second?
