alice-teacher Collision and walking speed questions

[James Vanderhyde]

1. Collision detection in Alice is tricky. I have had students try several different approaches, but nothing has really worked as well as I would like. There are some tutorials you can read (I found it with a Google search):

2. I don't think there's any way to modify those existing controls, so you have to write your own controls for the player object. One non-obvious feature that will be useful is that you can right-click on events (such as "when a key is typed") and change it to something else ("while a key is pressed").

I have an advanced student among all of my beginners... and he is working on a maze game.
2 questions:
1.   In Alice 2.3, is it possible to set up a collision indication method? If so, where do I find information on this?
2.  Is there a way to slow down the person object walking while using the arrow keys as controllers?
