C++ Vector Library - assign() Function

Description.

The C++ function std::vector::assign() assign new values to the vector elements by replacing old ones. It modifies size of vector if necessary.

If memory allocation happens allocation is allocated by internal allocator.

Declaration

Following is the declaration for std::vector::assign() function form std::vector header.

n − Size of vector.

val − Value for each element.

Return value

This member function never throws exception.

Time complexity

Linear i.e. O(n)

The following example shows the usage of std::vector::assign() function.

Let us compile and run the above program, this will produce the following result −

How to assign List>Vector3>[]

Hi am assigning an array of lists

but I keep getting this error:

Cannot implicitly convert type UnityEngine.Vector3 to System.Collections.Generic.List<UnityEngine.Vector3>

What does this error mean

Your mp.vectorPaths is not a

even though you might think it is. To prove this post the declaration of mp.vectorPaths here as well or double check. mp.vectorPaths is a 2-dimensional Vector3 array as the error message clearly says.

working, mark it as code sample.
