Solved Stop driveshaft from breaking

No realism needed. I need to make the driveshaft unbreakable.

 

You know what's funny?
I just uploaded a mod that does exactly that, awaiting approval now
Go to Lua > vehicle > drivetrain (if I remember correctly) and find shaft.lua, then comment out the things under onBreak.
This will largely give the desired effect, but things will get very sluggish if a driven axle is broken, so you'll have to change something that I can't recall right now under wheel(s?).lua for that.
Sorry for a bit of a sloppy reply, this is the best I can do right now
Hope you figure it out! If not, you'll be able to use mine in a day or so

 

It's a russian mod in remastering...

I tried it and it worked ! thanks man !!!!!

 

Agreed, jbeam is the better option unless you want it to apply to all cars like I did.

 

Also, if you want the driveshaft device to stop from breaking, you can make the named driveshaft beam unbreakable ("beamStrength":"FLT_MAX").

 

im not releasing the mod anyways so yeah ;D
