Once you have reference to the Actors you want to include in the Array, Right-click in the graph and add the Make Array node. Right-click in the graph and choose the Add Reference to Selected Actors option. The steps below will show you how to use the Make Array node.Īfter placing several Actors in your level (CameraActors in our case), select them all then open the Level Blueprint. In this example, say we wanted to have an Array of Camera Actors in our level that we can cycle between. In this case, you can use the Make Array node to create an Array out of a series of items instead of creating an Array variable and assigning Default Values. There may be instances where your Array is to be populated at runtime, for example, populating your Array with Actors that exist in your level. When creating an Array variable, you define the items that are to appear in the Array through the variable's Default Value setting. For the second item in the Array, you would enter 1 as the Index and so on. Keep this in mind when populating your Arrays, as you access the items in your Array by their Index value and if you wanted to access the first item, you would need to enter 0 as the Index value instead of one.

As seen in the last image, Array's use zero-based index values, meaning that the first index is zero and not 1.
