alice-teacher Question about built-in procedures

[McLean, Jennifer]

This is what I was doing so I didn't see a difference. - The command “moveToward (target, getDistanceTo(target))” will produce the same results as moveTo(target).

Thanks.

Jennifer,
moveTo animates movement of the object, in the direction of the target object (a 3D Model) until the pivot point of the object and the pivot point of the target are exactly the same; the original orientation of the object is unchanged.

moveTowards animates movement of the object, by the specified amount, in the direction of the target object (a 3D Model)…  the original orientation of the object is unchanged.

The command “moveToward (target, getDistanceTo(target))” will produce the same results as moveTo(target).

I have attached an Alice 3 project which illustrates the differences…

Let us know if you have any other questions…

All the best,
Don Slater

Hi,

I was reviewing the procedures with the class and I was unclear on how to explain the difference between the moveTo and the moveToward procedures. They seem to work the same way.

Thanks, Jennifer
