Let’s look at two very nice features of Tynker. The physics feature allows you to have falling objects and accurate projectile motion, combined with adjustments for gravity, friction, density, gravity, and much more. Cloning lets you have multiple instances of actors (like Scratch sprites), without having to duplicate code.

This lesson creates a simple calculator using a dictionary to look up functions for operators. The point is to practice more with dictionaries, and to learn about higher-order functions. Source code

Showing how to create multiple turtles in Kojo, and make them wander around. Uses Scala features map and foreach.

We show how to use Python's input function to get numbers, without the program breaking if something other than a number is entered.
