FWorldStaticVar<T>

FWorldStaticVar<T> is a class designed to manage static variables that are tied to the lifetime of a UWorld. This means the value is automatically cleaned up when the associated UWorld is destroyed, such as during level transitions.

Declaration and Usage

You can declare a world-static variable like this:

public static readonly FWorldStaticVar<float> MyStaticFloat = new();

To use it within your C# code:

public partial class AMyActor : AActor
{
    public static readonly FWorldStaticVar<float> MyStaticFloat = new();
    
    public AMyActor()
    {
        // Set the value to 70 in the current World
        MyStaticFloat.Value = 70;
    }
}
