ControlPoint

[fabioped]

Hi!

I'm using controlpoints a lot, and i'm having a bit of trouble with:

- How to know if an animationpath has ended? how to wait for it?
- Why isn't scale in controlpoints working in Vizard5?

Here's the sample code from the documentation:

import viz, vizact, viztask
viz.go()

viz.add("piazza.osgb")
model = viz.add('milk.osgb',pos=(0,1.5,4), scale=(0.01, 0.01, 0.01, ))
path = viz.addAnimationPath()

#Add control points to the path, along with their time stamp.
path.addControlPoint(0,pos=(2,1,5),euler=(90,0,0),scale=(2,2,2))
path.addControlPoint(3,pos=(-2,1,6),euler=(0,90,0),scale=(.5,.5,.5))

#Loop the path in a swinging fashion (point A to point B to point A, etc.).
path.setLoopMode(viz.SWING)

#Add a model.
ball = viz.addChild('beachball.osgb')

#Link the model to a path.
link = viz.link(path,model)

#Play the path.
path.play()

Thanks!!

How to know if an animationpath has ended? how to wait for it?

This feature was actually added recently and will be available in the next release (some time next week).

Why isn't scale in controlpoints working in Vizard5?

The behavior is actually the same as Vizard 4. By default, links will only apply the position and rotation from the source object to the destination. You need to modify the link mask to include scale values as well:

link = viz.link(path, model, mask=viz.LINK_ALL)

Thanks!

Can you also provide me a quick info?
Why is viz.addTexQuad no longer able to pick mouseclicks? viz.pick is returning empty on vizard5.
