Fmod team –

We’ve been experimenting with some math to calculate the Load value used in our engine model, but I was wondering if you could shed some light on the Load calculations you use for the engine designer Tool released with Fmod.

here’s a link to our calculation:

Thanks!

There is no particular logic in our code that you should be using in a game.

All our code does is make load move by a smoothed delta of the rpm value. We always assume that the game physics engine will have the right values coming back from the engine, its not really supposed to be ‘faked’ like fmod’s little popup dialog is.

From this thread http://52.88.2.202/forum/viewtopic.php?t=6399

andrew said it is calculated something like this

[code:2p19zz11]
targetload = ((rpm_slidervalue – rpm) * loadscale_slidervalue) + 1) * 0.5
rpm += ((rpm_slidervalue – rpm) * rpmsmooth_slidervalue)
load += ((targetload – load) * loadsmooth_slidervalue)
[/code:2p19zz11]
