alice-teacher How to orient part of an object to another object

[Don Slater]

You might take another object, perhaps something from the shapes gallery, put it at the tip of the lighthouse, set its "is showing" property to false, set its "vehicle" property to the lighthouse, and then the lighthouse movements can be based on the "as seen by" modifier referencing this invisible object.

Please let me know if you have any questions…

Later,
Don Slater
