Range library¶

A view represents an iterable sequence (it doesn't contain any container data)
There are two types of views:

Iterator: Modify Begin, End and Next of the loop
Predicate: Returns the element if the predicate is true

ForRange¶

A loop that can use multiple views (reverse, even etc ...)

How it works¶

The ForRange loop will iterate over a container and filter the results depending on the selected views

Example

// Given a container of integers:
0 1 2 3 4 5 6 7 8 9

// We first take the 3 first elements, then we reverse the result
take(3)
reverse()
Result: 2 1 0

// We reverse the container, then we take the 3 first elements
reverse()
take(3)
Result: 9 8 7

Create new views from blueprint¶

Create a new blueprint function library
Create a new function
- Create an input parameter that must be named __Element of the desired type
- Create an output parameter that must be named __Return of type bool
Write the function code and restart the editor

Example

Views¶

ActorInRange¶

Parameter
`Origin`	Location of origin
`Range`	Maximum range between Origin and Actor location

Even¶

Range¶

Reverse¶

Reverse elements order in a view
