I have 5 wav files, that I am trying to get 1 at a time to play when the vehicle hits a certain speed.
I am changing the sounds with the Volume control command but I dont know how to get the vehicle speeds that I want to use for changing the sounds. How can I find out the vehicles speed so I can get my wav files to play when I need them to?

teach you a neat trick i learned from one of the other forums a couple years back. If you type the partial name of a command in the editor and hit <ctrl>+<space> it brings up all the commands that start with the previous text. That is how i found this command for you i typed in "phy get" and a scrollable window popped up showing me all the return value commands for dark physics. It is also great for those realy long commands where you only have to type part of it and then grab it from the scrolling window.

float = phy get vehicle motor force ( ID )
Parameters

ID
identification number of the vehicle

Returns

motor force of a vehicle

Description

The motor force of a vehicle represents how much force is being applied to the motor. For example, if 0.0 is returned then no force is
being applied whereas if 100.0 is returned then a considerable amount of force is being applied to the motor and thus the vehicle will be
moving at quite some speed.

I keep getting a error when I try to use it.
"Command Line Out Of Place"

No matter where I put it, is there something I am missing cause of the Float command?

"command line out of place" usually means that you have an IF statement that isn't ended with an ENDIF. It also occurs when you have a "FOR i=x to x" command that isn't ended by a "NEXT i".

Search for DBA tidy on these forums and you'll be able to automatically format your text and see the nested commands nicely...

hope this advice is relevant and useful. I'm not saying you're a noob, cos i'm sure you already know this, i just felt the need to type

(edit)
Having re-read your post, You are using a command that returns a variable. this means you have two ways of typing it, see the following snippet:

+ Code Snippet

if phy get vehicle motor force ( ID )=1 then `blah

`or

null = phy get vehicle motor force ( ID )
if null=1 then `blah

Thanks for the help, I just had to add in my code to stop the wav from repeating itself. Now I just need to figure out how to setup the vehicle so it is MANUAL shift.

Ok, I got it to read the Force that the vehicle is moving at.

+ Code Snippet

FCE = Phy Get Vehicle Force (2)
Print FCE

But the problem is when I press the Up key the reading goes right to the Max vehicle force. It doesnt read the force that the vehicle is moving at untill it reaches its max force.

+ Code Snippet

if upkey ( ) = 1 then force=30 : set sound volume 1,100
If FCE(2)= 30 then Force=90 :set sound volume 1,0 :set Sound volume 2,100
If FCE(2)= 90 then Force=150 :set sound volume 2,0 :set Sound volume 3,100
endif
endif

I am trying something new. I am trying to get the speed to change according to the velocity but I just cant get it to work. Can anyone help me out with this?

+ Code Snippet

global vel as float
global avel as float


do
Velocity_Sound()
  sync
   loop


function Velocity_Sound()

   velx as float : velx = phy get rigid body linear velocity x (2)
   vely as float : vely = phy get rigid body linear velocity y (2)
   velz as float : velz = phy get rigid body linear velocity z (2)
   vel = sqrt((velx * velx) + (vely * vely) + (velz * velz))

 set sound speed 1,18000+(vel*975)

 ' Sound Moving Forward
if vel() = 15 then set sound volume 1,0 : Play sound 5 : set sound volume 2,100 :  set sound speed 2,18000+(vel*975)
if vel() = 20 then set sound volume 2,0 : pLAY SOUND 5 : set sound volume 3,100 :  set sound speed 3,18000+(vel*900)
if vel() = 25 then set sound volume 3,0 : Play Sound 5 : set sound volume 4,100 :  set sound speed 4,18000+(vel*850)


endfunction

Hi x_THOR_x
haven't tried your code, but one thing that jumps out at me is:-

Quote: "
if vel() = 15 then set sound volume 1,0 : Play sound 5 : set sound volume 2,100 : set sound speed 2,18000+(vel*975)
if vel() = 20 then set sound volume 2,0 : pLAY SOUND 5 : set sound volume 3,100 : set sound speed 3,18000+(vel*900)
if vel() = 25 then set sound volume 3,0 : Play Sound 5 : set sound volume 4,100 : set sound speed 4,18000+(vel*850)
"

vel() this is an array or function, can't see it set up anywhere, did you mean to type vel?

Yes I did, sorry about that.

   velz as float : velz = phy get rigid body linear velocity z (2)
   vel = sqrt((velx * velx) + (vely * vely) + (velz * velz))

 set sound speed 1,18000+(vel*975)

 ' Sound Moving Forward
if vel = 15 then set sound volume 1,0 : Play sound 5 : set sound volume 2,100 :  set sound speed 2,18000+(vel*975)

Text out the Vel value.. I guess its something like 0.002534
and not 25 or 15 you must multiple it with some value to get non decimal values. I think the multiply was something like 3.64 i dont remeber really anymore.
