4. Rotating Props

Another platforming obstacle common to the genre is objects that rotate, such as a spinning platform you have to constantly move on, or a bar that moves back and forth that you have to jump over.

The second component of an object’s transform is its rotation, and you can manipulate an object to rotate around an axis. There are several different ways you can use rotation to make unique platforming challenges, and you’ll learn how to code them in this section.

Making Props that Rotate

Follow these steps to build code that rotates your props:

1. Create a new Verse class named rotating_prop that inherits from movable_prop using Verse Explorer. Add the <concrete> specifier to this class to expose its properties to UEFN.

   
   
   |  | # A prop that rotates by an additional rotation or rotates to match |
   | --- | --- |
   |  | # a Creative prop's rotation. |
   |  | rotating_prop<public> := class<concrete>(movable_prop): |
