Gear ratios with manual transmissions
Posted: Thu Sep 06, 2007 4:34 am
Ok, probably the wrong forum, probably should be in a car forum , but I will give it a shot.
I am having a bit of trouble with how gears work in a car.
Lets say the engine is always running at 3,000 rpm.
In first gear the ratio is 2.315 : 1
In Second gear, the ratio is 1.568 :1
And so forth, untill you get to fifth gear.
Well as most of you guys who can read and understand english, I am making a car game.
So.. I could use someones help that knows alot or stuff about the transmission box.
In my signature is the latest release to my game, but here is the code I am working with right now.
where 3 = 3000 rpm
where rpm = rpm
where rpmm = rpm max - just like a real car
How would I get my car to work like a real car?

Code: Select all
If gear = 1 Then ratio = 2.315
If gear = 2 Then ratio = 1.568
If gear = 3 Then ratio = 1.195
If gear = 4 Then ratio = 1.000
If gear = 5 Then ratio = 0.915
If rpm < rpmm Then
rpm = 3 / ratio
EndIf
If rpm < 0 Then rpm = 0
where rpm = rpm
where rpmm = rpm max - just like a real car
