I am afraid that the problem continues as soon as I introduce further animation paths. I changed the one I had before to get the following: a trial triggers an animation that moves the viewpoint through a maze until a certain point when it wiats for an arrow key. Once a key is pressed it triggers one of two possible animations (going through left or right door). After this, immmediately, the next trial should start.

Problem 1:

This almost happens, only that the second trial starts at the point where the last door was, etc. I tried resetting the animation paths at various points and nothing seems to help.

Problem 2:

For some reason, it the right arrow key seems to not work. This seems to be a problem of the if statement, because even if I replace the arrow key with the space bar, it does not take the "elif" statement...

I would highly appreciate any pointers in the right direction!
