How to damage rod bearings?

Just a small question that's all, how do you damage rod bearings and piston rings?

 

I think this can be done by holding the throttle until the engine overheats. It's especially easy to do on older cars that don't have rev limiters.

 

Thats how you bend valves. In this case, damage the radiator or remove it entirely.

 

There is damageTracker.setDamage() which needs three parameters, group, name, value which group and name are something that I don't know, those probably could be found though from some files of steamapps\common\BeamNG.drive\lua\vehicle.

damageTracker.lua is where you can see that function, then it is some other file where is defined names for group and name parameter.

Something like damageTracker.setDamage(engine, conrodbearing, 1) given to console Vehicle lua side would then damage bearings, but what are actual keywords for engine and conrodbearing is that needs to be found and sadly I don't have hours to read numerous different files to find out that parameter, but that is how one enough time and interest can find out about it.

With this I get game to give message about reduced torque:
damageTracker.setDamage("engine","engineReducedTorque",1)

Not really sure if there would be keyword for bearing, but maybe that helps someone to explore more.

combustionEngine.lua has some codes like:
damageTracker.setDamage("engine", "engineIsHydrolocking", isFlooding)
damageTracker.setDamage("engine", "engineLockedUp", true)

But these don't actually kill the engine, so not sure where one can found code that actually initiates these and makes actual damage.

Well, had to look and this sets bearings damaged, but only in UI App, not in engine itself, but probably there is some other command which this can be used to set damage for the engine:
damageTracker.setDamage("engine", "rodBearingsDamaged", true)

There is also this in combustionEngineThermals.lua:
M.connectingRodBearingsDamaged

It might work like this:
Something.connectingRodBearingsDamaged=true

Only problem is I can't figure out what that something could be.

This is why that brick thick manual of available keywords etc. would be nice.

 

Thanks for this, I didn't expect such an in-depth reply but it gives me something to look into

oh i found out that it was this:
drivetrain.engine.connectingRodBearingsDamaged = true

However, it doesn't work when I put it into the console...

 

I'm thinking here that code you have probably is still indicator or reporting side of things, maybe we need to look how to set connectingRodBearingDamage instead, as there is connectingRodBearingDamageTreshold set in jbeam file, if we can figure out how to set value of connectingRodBearingDamage higher to that said treshold, it should do the trick.

You can give command like dump(powertrain) to get list of available keywords.

There is also dump(electrics), but haven't figure out all. For example there should be way to shutdown or disable engine, which could be handy for making story elements for a mission, but without knowing more what is available it is bit hard to reverse engineer this.

There is very tiny bit of stuff in here, but maybe you can find it interesting too.

thanks again
