If you find yourself needing to load your mod classes from a dedicated "Mods" folder when your Minecraft mod loader starts up, you’re in the right place. In this guide, we’ll explore how to achieve this with the help of Java’s URLClassLoader. The Challenge As part of your mod loader development, you've defined a class named Client, which acts as the main entry point for your Minecraft mod. The goal is to load all the mod classes located in a "Mods" folder into your modules ArrayList when the game starts. Each mod must extend a Module class you've defined to ensure the proper functionality of toggling and enabling mods. The Solution To tackle this problem of loading mod classes dynamically, we will use the URLClassLoader class provided by Java. Here's a step-by-step explanation of the solution: Step 1: Setup the Mods Folder First, ensure that you have a folder named "Mods" in the appropriate directory where your mod loader can find it. This is where you will place all your mod jar files. Step 2: Create a URL Array from Files You need to gather all the files in the "Mods" folder and create an array of URLs that the URLClassLoader can utilize. Here’s how to do that: [[See Video to Reveal this Text or Code Snippet]] In this snippet, we’re getting a list of files in the "Mods" directory and converting each file into a URL. Step 3: Load the Classes Once you've set up the URLClassLoader with the URLs of the mod files, you can load the classes by specifying their fully qualified names. Here’s how: [[See Video to Reveal this Text or Code Snippet]] In this code, replace "fully.qualified.name" with the actual package and class name of your mod. This checks if the loaded object is an instance of Module, and if so, adds it to your modules list. Step 4: Optional - Use Reflections to Discover Classes If you're not sure about the names of the classes within the jar files, you can use a library called Reflections. This gives you the ability to scan and discover classes at runtime, making the loading process much smoother. Final Thoughts By utilizing URLClassLoader, you can effectively load jar files from a separate "Mods" directory into your Minecraft mod loader. This enhances modularity and keeps your project organized. Now, as you develop your mod, you can dynamically add or remove mods without needing to change the main codebase.
