BVE: Sound & Power Delay

[AngliaTrains]

Hello People,

I would like some help, I'm trying to do something for a sprinter unit. How could I make the 'motor0' (reeving up) sound play and then the train not moving until about 2/3sec's after.

I'm trying to simulate the engines reeving up before the train actually has momentum.

Thanks,

RE: Sound & Power Delay

I don't know much about train building, but I have played around with the train.dat files from time to time. Can you not put a very low acceleration rate on the first notch or two, so that in effect the train does not move unless it's in a higher notch? I know that a lot of users just seem to "stick it in the top notch", but if it was driven correctly you might be able to manipulate the sounds and movement to obtain what you want.

Just being able to rev the engine cannot be done in BVE as I'm sure that you are aware.

RE: Sound & Power Delay

Have a look (and listen!) at how the 158 is done*:

motor2.wav - start up and pull away (26 secs of sound)
motor0.wav - acceleration under torque converter
motor5.wav - 'gear change' to direct drive
motor6.wav - acceleration in direct drive

I'm not sure of the speed ranges used for the sounds (you'll need to peer at the train.dat file for that) but if you follow the driver's guide and start away on notch 3, changing to notch 7 as the train begins to move, the engine note follows the controller pretty closely. So it seems to be that you need to know how the train was being driven when you recorded it, so that you can move the controller at the right time - a case of the tail wagging the dog, but that's all BVE really allows us ATM.

*AFAIK, this scheme was first used by John Owen's 150/2.

RE: Sound & Power Delay

Thanks for that chaps,

Had another idea and is it possible?

In order;

(Waiting at station)

- Guard sends buzzer twice
- Driver sends buzzer back
- Brake notch to 1
- Apply 2 notchs of power (Enging rev's)
- Completely release brakes and slowly apply more power.

Is that possible, I think at one time that was how your suppose to drive MU's. Not sure if its the same now but, would it be possible?

Thanks again.
