Touch Controller Problem
 
Hi I would like to use the touch controller to control the movement of a scooter.

The ideal scene would be each time I load a road scene and the rider starts accelerating then rides the scooter to the end point at a constant speed. However, I am currently encountering two problems:

1) When I start running the script, only part of the scene can be loaded;
2) It seems the touch button events can not be detected as the text 'done' I inserted can not be printed out.

Can someone help me out with this pls?????:(

##### Create skylight
viz.MainView.getHeadLight().disable()

Dear tianmoran,

I believe you received support for this question in the WorldViz Ticked Based support system for customers with support contracts, right?

Please let us know if this is still an open issue,

thanks and all best,

Matthias
