These will serve as the locations at which to spawn our effect. Inside your project, from the Place Actors panel in the All Classes tab, drag 5 Target Points into your level.
In this example, we will use Arrays to spawn a random Blueprint effect in our level at a random location.įor this example, we are using the Blueprint Third Person Template project with Starter Content enabled. Below, this setup could be used to drive the cycling between Camera Actors that are placed in the level. Through some form of script, you could Set the Get Camera to an Integer value, effectively changing which Camera Actor is selected in the Get node. This could also be an Integer variable as depicted below as the variable called Get Camera. The value in the box on the Get node is the Index (Array Element) to access (Get) from the Make Array node. This will convert the Array into an Array Type for the selected Actor (the Error message will disappear when you compile).Ĭonnect the rest of your Actors to the remaining pins on your Make Array node.ĭrag off the Array pin, search for and add the Get node. On the Make Array node, click the + sign to add the amount of pins needed for each of the Actors to appear in the Array.ĭrag off one of your Actors and connect it to the 0 (or any other pin) on the Make Array node.
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.
