Offset position of link/attached object

How do you change the relative offset of an attached object when using viz.link? Is this possible? setPosition doesn't work and there doesn't seem to be a set relative position function. Also need the rotation as well.

You can apply a postTrans or preTrans operation on the link.

Thanks, I already figured out what I needed to. However I am having a few issues implementing a FPS style control scheme where the change in mouse position rotates the player. Here's pastebin of relevant code:

This code is contained within my function UpdateView and gets updated with the following:

vizact.ontimer(0,UpdateView)

Now this code works, however, it is very jittery. It is not smooth at all. And if I only move the mouse a little bit, it wont cause the player to rotate. The way Im doing this feels very "hacky", but I'm not sure how else to do it. I haven't any example code for this kind of control scheme. Is there a better way to accomplish this? To me it seems like the UpdateView function is not being called every frame which is the cause of the jitteryness, but I am not entirely sure.

One of the built-in cameras from the vizcam library may set up the navigation style you would like:

Code:

import viz

viz.go()



import vizcam

vizcam.FlyNavigate(forward='w',backward='s',left='a',right='d')

#vizcam.WalkNavigate()



viz.addChild('piazza.osgb')
