Translate Head Pos to Starting Pos via Key
 
Hi there,

I'm trying to make a key function to reset the user's HEAD_POS to a starting position in the world. The code I have is like the following:

def mykeyboard(key):
if key == 'a':
viz.translate(viz.HEAD_POS, -0.1439, -.0095, -4.4603, viz.ABSOLUTE_WORLD)

[where (-.1439, .0095, -4.4603) is the exact position I want the user's head to be in when I press the 'a' key]

However, when I do press the 'a' key when I run the script, it ends up translating the head_pos relatively each time (in this case, back a few coordinates on the z-axis). How do I fix this?

Thanks!

Hi,

The viz.translate function will only translate the viewpoint relatively. To translate the viewpoint to an absolute location, use the translate command of the main viewpoint:
Code:

view = viz.get(viz.MAIN_VIEWPOINT)
view.translate(-0.1439, -.0095, -4.4603)

Look in the section of the command reference for more information.
