Randomly and Continuously Change Avatar's Face Texture

[Karla]

I would like to make a Sequence that Waits 2-6sec., Randomly changes the texture on the avatar's face, and Repeats.

Based on the post
http://www.worldviz.com/forum/showthread.php?t=776
the texture needs to be set to repeating mode.

Otherwise, the face is blacked out.

See attached files and code.

Thanks,
Karla

Here is some sample code that uses the vizact library to create an action that does what you want.import viz
viz.go()

#Create quad for displaying texture
quad = viz.addTexQuad(pos=(0,1.8,2))

#List of texture filenames
files = ['ball.jpg','gb_noise.jpg','brick.jpg','lake3.jpg']

#List of texture objects
textures = [ viz.addTexture(f) for f in files ]

#Create action that randomly waits between 2-6 seconds
waitTime = vizact.waittime( vizact.randfloat(2.0,6.0) )

#Create action that randomly applies texture from list above
randomTexture = vizact.texture_node( vizact.choice(textures,vizact.RANDOM) )

#Create sequence that repeats above actions indefinitely
my_action = vizact.sequence( waitTime, randomTexture, viz.FOREVER )

#Add action to quad
quad.addAction(my_action)

Thanks for the suggestion. It works for quad objects but not for the avatar's face.

The avatar's face becomes blacked out when the texture is applied. There seems to be a difference between applying a texture to an avatar's face and applying it to other objects. I am having a similar problem as in post
http://www.worldviz.com/forum/showthread.php?t=776

Using 'texture.wrap(viz.WRAP_S,viz.REPEAT), texture.wrap(viz.WRAP_T,viz.REPEAT),' applies the texture correctly to the avatar's face. Therefore, it is not blacked out when using 'wrap.'

How can I incorporate 'wrap' with the random texture application? An error message said "'ActionData' object has no attribute 'wrap'."

Thanks,
Karla

Then set the the textures to repeat mode when you add them:textures = [ viz.addTexture(f,wrap=viz.REPEAT) for f in files ]

THANK YOU! THANK YOU! That code solves what I want.:D
