The vehicle update is overall really great and interesting to look through, but there are, in my opinion, some quite important things to add or to fix.
Also don't mind my english if it turns out to be bad <3
1. Tire slip
Currently even on vanilla cars the driven wheels are constantly spinning faster than non-driven ones, it just looks weird, and also, wheelspin doesn't affect traction at all.P.S. I've seen that you're planning on revising wheel collider friction, but just in case i wrote that.
2. Tire smoke and skidmarks on asphalt
Currently there are no sounds or smoke coming from slipping tires on asphalt, that would be a nice detail, and considering that you've already made such thing in Unturned II, I think it's also planned here, but still.3. Gearbox
Overall it works alright, but sometimes when driving on high speeds and pressing S to brake, it shifts into reverse, cars in real life don't do that.And also, it would be great to see manual gearboxes sometime in the future. Q and E buttons are great candidates for shifting gears in my opinion.
4. Vehicle Event Hook
With all these added mechanics we really need more events for VehicleEventHook.Events like onShiftUp, onShiftDown would be incredibly useful for modders to create new mechanics.
5. Engine_Additive gameobject
Audio source on Engine_Additive gameobject doesn't work anymore. I don't know if it's intentional or not, but still.6. Revlimiter
Or rather, the lack thereof. Modern engines use the thing called revlimiter It works in such a way that when the maximum RPM are reached, the fuel supply is turned off for a split second, and then turned back on. During this fraction of a second, the engine RPMs manage to drop to a safe value. And then cycle continues. All of that lead to a specific sound that engine makes when approaching its maximum RPM. Here is an example of how that may sound: https://www.youtube.com/watch?v=EksneDnCf8EIt really gives the feeling of power to the car, that would be a great detail to add in the future.
7. Brake and reverse lights
Since we have get brakes now, could we, perhaps, also get brake lights? Tail lights currently work in a very weird way, it was done right in Unturned II, and it needs to be done right here also. It's a small detail but it adds so much to the immersivity.And it would be also great to have a modhook that listens to the events of braking or reversing, just saying.
