UE4For each loop

In UE4, a "for each" loop is a type of loop that iterates through a collection of objects and performs a set of actions on each object in the collection. The loop can be used to perform a variety of tasks, such as updating the properties of each object, executing a certain function for each object, or checking certain conditions for each object.

The syntax for a for each loop in UE4 is as follows:

for each (Object in Collection)
{
    // Perform actions on Object
}

Here, "Object" is a variable that represents each object in the collection, and "Collection" is the collection of objects that the loop is iterating through. The actions to be performed on each object are placed inside the braces.

For example, let's say we have a collection of actors in our level, and we want to set the visibility of each actor to false. We can use a for each loop to accomplish this:

for each (AActor* Actor in Actors)
{
    Actor->SetActorHiddenInGame(true);
}

Here, "AActor" is the type of object we're iterating through, "Actor" is the variable that represents each actor in the loop, and "Actors" is the collection of actors we're iterating through. The loop sets the "Hidden In Game" property of each actor to true, effectively hiding them from view.
