alice-teacher Compare colors

[Don Slater]

You are correct… It is not possible at this time in Alice 3 to check to see if an object has a specific color or paint value.

The only workaround that I can suggest, and it is not pretty, is to create a string variable for the object class that will hold the color name (i.e. “blue”) and then compare that string against your target value. But this will require that every time you change the color of an object, the object variable also has to be changed.

I am sorry,
Don Slater
