Active Sky Offsets

[DLuis]

Hi,

 

I'm developing a little software with environment sounds, but I'm stock with two of them.

I would like to have turbulence and rain sounds.

For Turbulence, I would like to play a sound every time the airplane "shakes". For the rain, play a loop sound, but only when the rain hit's the cockpit "below the clouds".

 

I've Active Sky 4, so does anyone know what offsets can I use to achieve this? I've used 0x0E88 and 0x0E98 for turbulence, but doesn't give me the expected result. For the rain, doesn't have a single idea.

Is there any API of AS4 to achieve this?

 

Thanks in advance.

Hi.

Active Skye ambient turbulence at aircraft is at offset 8638, and precipitation at 8640. From the offsets documentation, ActiveSky  offsets are:

8638	4	ActiveSky needed: Ambient turbulence at aircraft (0-1000), 32- bit float
863C	4	ActiveSky needed: Exported ambient visibility (metres), 32-bit float (-ve if not supported)
8640	41	ActiveSky needed: Exported precipitation type (0 none, 1 rain, 2 snow, 3 hail), 8-bit integer (Byte)
8641	41	ActiveSky needed: Exported precipitation rate (0-4), 8-bit integer (Byte)
8642	41	ActiveSky needed: In cloud flag (non-zero if aircraft is in cloud), Byte

** the byte offsets (8640, 8641, 8642) are 1 byte not 4 (obviously!) - I'll correct the documentation for this [I did strikethrough the incorrect '4' size above, but the strikethrough is not so obvious on that number!] **

Cheers,

John

Hi John,

 

Thanks a lot for the quick reply. 

I've search in Active Sky docs and in the WX radar facilities docs and didn't notice this information in the offsets documentation.

 

Now I know where to start :D

 

About the offsets length, yes, they are bytes. 

Once again, thank you for the help.
