Vehicle Ignition System Changes

I do not know how to make mods

 

The idea is cool, but realistically, it’s pretty much impossible to simulate engine heating and cooling properly in BeamNG without running into major issues.

I’ve talked to a dev about this, and it turns out a full thermal simulation would need constant calculations even when the car is off — like tracking heat transfer between the engine block, coolant, oil, ambient air, radiator airflow, and even stuff like heat soak into components. That kind of thing would absolutely destroy performance, especially on lower-end PCs.

Also, the game doesn’t simulate time like real life. When you change the time of day, it only moves the sun and sky — it doesn’t actually fast-forward physics. To cool an engine over time, the game would need to simulate hours of physics in seconds, which just isn’t viable. And building a separate background system for it could easily get inaccurate or buggy.

I suggested making it a high-end PC option, but they said that kind of split would cause complaints — people asking why they can’t access certain features, even if their system can’t handle it.

So yeah, awesome idea in theory, but it’s way more complicated than it seems.

 

They dont need to do that. Just improve the physics they have. Like make the times realistic, they dont need to work out heat transfer and all that nonsense just have it so cars heart up and cool down in a better timeframe. They already have the basics

 

Since the ignition system needs a battery. Can we have battery damage and be able to rip batteries out of cars? Please?

 

We don't need so much detailed heating physics. it's enough just to improve a little what we have now. It's just that the car warms up more, but the radiator can keep the right temperature when the thermostat is turned on. So that road cars overheat when driving at the limit of their capabilities, but prepared cars do not.

 

I also suggested something a bit simpler, but the answer was still a no.

 

hazard not working when the ignition off

 

I forgot to mention that

 

its not supposed to

 

Do me a favor. Go to your car and activate the hazard lights real quick without turning the key or putting the key in. Just do it. See what happens.

If nothing happens then you were right. But if it does activate the hazard lights then it's because the hazard lights are wired independent and bypass the ignition system due to safety concerns and safety reasons that automotive designers had to think around. Because if you need to take the key from the car and you need to leave the car for a bit but you have to leave the hazards on.... Then yeah, has lights need to be independent from the ignition system

 

I did this, and uh- nothing happened. Then i realised that my car has no engine-

 

Well if it has no electrical system or battery powered anything then of course nothing's going to happen but most vehicles can operate the hazard lights without even touching the ignition or needing the ignition on. And you see cars on the side of the road that have had car alarms go off and you don't touch the ignition and stuff. That's a bypass past the ignition. Some electrical systems and cars do that like the interior lights for example. You don't need to turn the car's ignition on to touch the lights.

BeamNG drive desperately needs a battery and MPG update. BAD. JUST A HUGE qol improvement
