Touch Controller Problem

[tianmoran]

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?????
