Functions in Unreal Engine Blueprints are reusable blocks of logic that help you organize and simplify your gameplay scripts. Instead of repeating the same series of nodes, you can create a function to handle the logic and call it whenever needed. This makes your Blueprints cleaner, easier to understand, and more efficient.<\/p>\n\n\n\n

To create a function, open the Blueprint Editor and look for the My Blueprint<\/strong> panel. Under the Functions<\/strong> section, click the +<\/strong> button and name your function. Double-click the new function to open its editor. Here, you can add nodes to define what the function will do.<\/p>\n\n\n\n

Functions can take inputs<\/strong> and provide outputs<\/strong>. Inputs are values that you pass into the function when you call it, and outputs are the results it returns after performing its task. For example, you can create a function to calculate the player\u2019s score:<\/p>\n\n\n\n

    \n
  1. Add an Input<\/strong> parameter by clicking the +<\/strong> icon in the Details panel. Name it PointsEarned<\/code> and set its type to Integer.<\/li>\n\n\n\n
  2. Add a Return Node<\/strong> at the end of the function to provide the output. For example, you can calculate the total score by adding PointsEarned<\/code> to a variable and returning the new value.<\/li>\n<\/ol>\n\n\n\n

    To use the function, go back to the Event Graph and drag it from the My Blueprint<\/strong> panel into the graph. Connect it to the logic where you need it. Whenever the function is called, it will execute the nodes inside it and return the output.<\/p>\n\n\n\n

    Functions can also be customized as:<\/p>\n\n\n\n
