6.22 RPL

The RPL method allows you to create your own RPL procedures and associate them with objects. When the animation is played, your procedure is executed in each frame and it is totally up to your procedure to decide what to do when this happens.

Because RPL is a full featured programming language, there is not much you could NOT do with it. In a way, this method is one of the most powerful ones found in the program, but naturally, in order to take full advantage of it, you have to know how to write RPL programs. All built-in methods, such as PATH, SIZE, RADIAL FORCE etc. can be easily implemented using the RPL method.

Because this subject is huge, we will go through only a basic example here. For more information about how to write new animation methods using RPL, see the RPL tutorial and the Reference manual.
