First off, I am not asking for a script, just ideas/suggestions. I have a physics model for my vehicle that does not use any sort of wheelcolliders and instead just uses addforce and addtorque to the car. Does anyone have any suggestions for calculating an (albeit fake) RPM value for the engine?
First of all RPM is for rotating object but if you want fake rpm then try setting it using rigidbody velocity magnitude or z direction velocity etc… You can add some value to it depending on input etc. Hope this will help
