This differs from the original loop by starting at the end of the array and working backwards towards the start. The last type of For Each loop is the reverse for each loop.

You would loop through every index until you found a stack of this item, check if this stack is not full then break the loop as no more processing is required. This gives you the option, similar to the For Loop with Break, to end the loop at a certain point if your required condition is met.Īn example of this is looking for a specific item inside your player’s inventory. The for each node has a variety called for each with break. When working with your arrays, these are the most useful as it gives easy access to current array elements and its respective index. The for each loop takes an array as an input and gives easy access to every element inside such array.įor Each Loops are especially slow to process in blueprints compared to C++ so try not to use them very often in your blueprint classes.

This is especially useful when optimising loops as many loops don’t need to be fully run through if your code has done what it needs to do. The For Loop with Break node gives you the option to end your loop early if required. Once your loop has finished the completed pin will execute. Loop body is the pin in which you connect the code you wish to loop through. The loop will execute and add 1 to the index value, returning this value in the index pin on the right. The ForLoop node gives you the choice of which index to start at and which to end at. This will execute your desired blueprint nodes X amount of times based on your settings. Make sure to use delays inside the loop to prevent the maximum iteration counter from stopping your game running. This executes while the input Boolean is true.īe careful when using While Loops as they can easily cause the engine to detect and infinite loop. The simplest type of loop is the While Loop. Loops iterations are slow to process so use them sparingly! While Loop

When you need to remove all array elements use the CLEAR node: Loops To check if your array contains a specific element/value use the FIND ITEM node: Setting a specific array element to a new value uses the SET ARRAY ELEM node: Removing a specific index in your array uses the REMOVE INDEX node: To add an element to the end of your array use the ADD node: For the complete list of array nodes click here.Īccessing a specific index in your array uses the GET node: Your array is now fully setup! Accessing your Arrayīelow are the main blueprint nodes that you will be using when accessing your arrays. Separate floats have now been created and can be changed independently of each other.

Now you can populate your array with the plus button. In this case I used a float.Ĭreate the variable, press the button to the side of the variable type then select the array button to convert this variable to an array. Creating an Arrayįirstly create a variable of the type you want. An array is a sequence of objects that are all of the same type.įor a further theory dive into arrays using C++ click here.
