Windows
MacOS
Linux

Syntax

template<typename CountType>
void RemoveAtSwap
(
    int32 Index,
    CountType Count,
    bool bAllowShrinking
)

Remarks

Removes an element (or elements) at given location optionally shrinking the array.

This version is much more efficient than RemoveAt (O(Count) instead of O(ArrayNum)), but does not preserve the order.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
