Repeat List

Description

This node is used to repeat a list a specific number of times.

Loop - This option is the standard repetition pattern. Input list [1,2,3] repeated 2 times will output [1,2,3,1,2,3].
Ping Pong - This option is a repeat reverse pattern. Input list [1,2,3] repeated 2 times will output [1,2,3,3,2,1].
Amount - This option lets you define the amount of repetition.
Length - This option lets you define the length of the output list. The amount of repetition is set automatically to fill that length, all the elements which exceed that length will be cut off. If the length is 5 in the previous example, the output list will be [1,2,3,1,2] Notice that the second 3 was cut because it exceeded the defined length.
Below Length - Just like Length this option allow you to define the length but if the length was not sufficient to complete a whole repetition, that last repetition will be rejected. So if the length is set to 5 in the previous example, the output will be [1,2,3]. Notice that the whole second repetition was rejected because it didn’t make it to the last element.
Above Length - Just like Below Length this option allows you to define the length but if the length was sufficient to add at least one element from the last repetition, the whole last repetition will be added. So if the length was 5 in the previous example, the output will be [1,2,3,1,2,3]. Notice that the second 3 was not supposed to be in the list but it was added anyway.

Make Element Copies - Copy the element before repeating them. This makes sure the elements are independent of the original elements in the list and so changing those elements won’t affect the following repetitions.
Change type - Change the type of the list to another list type.
