WIP Beta released Emit exhaust smoke if piston rings are damaged

Tested on 0.24.1.3.

Engines should emit blueish smoke if piston rings are damaged, due to engine oil consumption. Even one of the loading screen tips says this is a thing. And there is a code for this but it doesn't seem to work. This mod enables dark/black smoke when engine is running with damaged piston rings. Its not blue, but the effect is still good. It does not check if we still have oil so it still emits smoke with no oil.

This mod overwrites "combustionEngineThermals.lua" core lua file. Contents of this file may change between updates (for example version 0.24.1.3 differs a bit from version 0.24.0.2), so this mod can easily mess your game after update.

It just adds this code right under the "M.headGasketBlown" part:

Code:

--smoke from broken piston rings
    if M.pistonRingsDamaged and particleTicks.exhaustSteamParticleTick > 1 and not (parentEngine.isDisabled or parentEngine.isStalled) then
      --emit smoke from exhaust because of engine oil consumption
      obj:addParticleByNodesRelative(n.finish, n.start, absEngineRPM * -0.0004 - 3, heavySmokeParticleType, 0, 1)
    end

You can add exhaust smoke for your old rust bucket cars for roleplay reasons by damaging piston rings with lua command like this:

Code:

powertrain.getDevice("mainEngine").thermals.pistonRingsDamaged = true

Or use this in your scenario .json file like this:

Code:

    "vehicles":
   {
        "scenario_player0":
       {
           "driver":
           {
               "player":true,
                "startFocus": true,
                "required": true,
                "command": "powertrain.getDevice('mainEngine').thermals.pistonRingsDamaged = true",               
           },

To have it automatically applied on scenario start.
