Scripting for Audio capabilities

[richards christopher]

Hi all,

Is it possible to control audio capability added to an object through
script. I need to control the playing of audio and the number of files
played at a time based on user inputs. I could not find much info
about scripting for the audio component. Is it possible? if not, is
there any other way i can do it? Thanks in advance


Regards,
Richards

In order to control the audio capability via scripting, it will be necessary to put the scripting command structure into the audio capability module. A good example of how that all works is the npc module. Look in the NpcCell.java code. You will have to find the code in the audio capability cell code that performs the various functions that you want to perform and attach scripting commands to those.

Hi Morris
Thank you for the info. Basically i am trying to simulate the working
of an audio mixer using open wonderland. I have created the model and
made parent child relation to the body of the mixer and different
faders and knobs. i have brought the model inside wonderland. will i
be able to access the individual faders and knobs and add animation to
it seperately? i tried importing a single fader separately and tried
to add an animation by adding the following script.


fader.translateX=1.0

as mentioned in the bug example. but i could not get it right. i got
the following error while i tried to save the script.

Hi Morris ,

II got it right. i did not enable the user script checkbox. However i
have the other doubts. is it possible to add scripts for an object
which has a paren child relation seperately? ( seperate script for the
child) Or Should i bring both the objects seperately in to wonderland
and arrange it inside.(its too tedious to do that). is there any other
alternative? please help. Thanks

If you want to animate objects separately they should be separate objects. An exception to this would be a model created in Maya or Blender that has multiple nodes and there are animations for the separate nodes created in that tool. This can get pretty complicated to create and to animate in OWL.
