alice-teacher Amusement Park - making objects solid

[Harrod Patrick L.]

I have had this same issue, and have not found an easy solution to address it. Do you then use an If/Else statement for the 2 objects?

One thing you can do is to use one of the distance functions for objects to detect when their center’s are a certain distance from each other.  If you go inside this distance, you can essentially make it so the object bounces off the other object it is approaching.  I hope this makes some sense.  Our student created video games for a major project and had to incorporate this idea.

Hi All!

I am new to Alice and am exploring the program with my programming club first.
I have downloaded Alice 2.2 and am running on Windows machines.

The students asked the following questions that I hope I can get some answers here or at least a point in the right direction/tutorial.

In the amusement park example world, I have had a student add an object (Angel for example) and then use that object as the vehicle for the camera.  He then uses the arrow keys to get the object to explore the amusement park world.  How do you get an object to not go through other objects while using the keyboard arrow keys?

Also in the amusement park world, when you explore the world, you slowly sink into the ground (the camera angle is not level with the ground).  How do you change this?

Thanks, in advance, for your help.  Also, if this is not the right forum for this type of question, let me know where a good place would be.
