Code Snippets/Classes

Strikingwolf · Sep 19, 2014

This is intended to be a place where you post general code snippets to do crap

Basic Classes
How about I start us off with the most basic classes of all, the base mod class, my counterpart for it the Reference class, and the proxy classes

Base Mod class for you (Requires Reference and Proxy classes)

Code:

@Mod(modid = Reference.MOD_ID, name = Reference.MOD_NAME, version = Reference.VERSION)
public class ModName
{
    @Mod.Instance(Reference.MOD_ID)
    public static ModName instance;

    @SidedProxy(clientSide = Reference.CLIENT_PROXY_CLASS, serverSide = Reference.SERVER_PROXY_CLASS)
    public static CommonProxy proxy;

    @Mod.EventHandler
    public void preInit(FMLPreInitializationEvent event)
    {
        //Optional if you have ConfigurationHandler setup
        //ConfigurationHandler.init(event.getSuggestedConfigurationFile());
        //FMLCommonHandler.instance().bus().register(new ConfigurationHandler());

        //Optional if you use the LogHelper
        //LogHelper.info("Pre Initialization Complete");
    }

    @Mod.EventHandler
    public void Init(FMLInitializationEvent event)
    {
        //Optional if you use the LogHelper
        //LogHelper.info("Initialization Complete");
    }

    @Mod.EventHandler
    public void postInit(FMLPostInitializationEvent event)
    {
        //Optional if you use the LogHelper
        //LogHelper.info("Post Initialization Complete");
    }
}

For all your referencing needs

Code:

public class Reference
{
    public static final String MOD_ID = "ModID";
    public static final String MOD_NAME = "ModName";
    public static final String VERSION = "VERSION";

    public static final String CLIENT_PROXY_CLASS = "mods.modname.proxy.ClientProxy";
    public static final String SERVER_PROXY_CLASS = "mods.modname.proxy.ServerProxy";
}

For all your proxy needs

Code:

public interface IProxy
{
    public abstract void registerKeyBindings();
}

Code:

public abstract class CommonProxy implements IProxy {

    public void initSounds()
    {

    }

    public void initRenderers()
    {

    }
}

Code:

public class ServerProxy extends CommonProxy {


    @Override
    public void registerKeyBindings() {
        //NOOP
    }
}

Code:

public class ClientProxy extends CommonProxy {

    @Override
    public void initSounds()
    {

    }

    @Override
    public void initRenderers()
    {

    }

    @Override
    public void registerKeyBindings()
    {

    }
}

Utility

Also the LogHelper class is very helpful when doing anything logging related (requires Reference Class)

Code:

public class LogHelper {
    public static void log(Level logLevel, Object object)
    {
        FMLLog.log(Reference.MOD_NAME, logLevel, String.valueOf(object));
    }

    public static void all(Object object)
    {
        log(Level.ALL, object);
    }

    public static void debug(Object object)
    {
        log(Level.DEBUG, object);
    }

    public static void error(Object object)
    {
        log(Level.ERROR, object);
    }

    public static void fatal(Object object)
    {
        log(Level.FATAL, object);
    }

    public static void info(Object object)
    {
        log(Level.INFO, object);
    }

    public static void off(Object object)
    {
        log(Level.OFF, object);
    }

    public static void trace(Object object)
    {
        log(Level.TRACE, object);
    }

    public static void warn(Object object)
    {
        log(Level.WARN, object);
    }
}

KeyHelper; detects shift/control with proper Mac support contributed by @squeek502

Code:

public class KeyHelper
{
   public static boolean isCtrlKeyDown()
   {
     // prioritize CONTROL, but allow OPTION as well on Mac (note: GuiScreen's isCtrlKeyDown only checks for the OPTION key on Mac)
     boolean isCtrlKeyDown = Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL);
     if (!isCtrlKeyDown && Minecraft.isRunningOnMac)
       isCtrlKeyDown = Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA);

     return isCtrlKeyDown;
   }

   public static boolean isShiftKeyDown()
   {
     return Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT);
   }
}

ColorHelper; converts between the common color types used within Minecraft code (hexadecimal color using an int, rgba using ints from 0-255, and rgba using floats from 0.0-1.0) contributed by @squeek502

Code:

public class ColorHelper
{
   public static float[] toNormalizedRGB(int color)
   {
     return toNormalizedRGBA(color | 255 << 24);
   }

   public static float[] toNormalizedRGBA(int color)
   {
     int[] rgba = toRGBA(color);

     return new float[]{rgba[0] / 255f, rgba[1] / 255f, rgba[2] / 255f, rgba[3] / 255f};
   }

   public static int[] toRGBA(int color)
   {
     int alpha = color >> 24 & 255;
     int red = color >> 16 & 255;
     int green = color >> 8 & 255;
     int blue = color & 255;

     return new int[]{red, green, blue, alpha};
   }

   public static int fromRGBA(int r, int g, int b, int a)
   {
     return (a & 255) << 24 | (r & 255) << 16 | (g & 255) << 8 | b & 255;
   }

   public static int fromRGB(int r, int g, int b)
   {
     return fromRGBA(r, g, b, 255);
   }

   public static int fromNormalizedRGBA(float r, float g, float b, float a)
   {
     return fromRGBA((int) r * 255, (int) g * 255, (int) b * 255, (int) a * 255);
   }

   public static int fromNormalizedRGB(float r, float g, float b)
   {
     return fromNormalizedRGBA(r, g, b, 1f);
   }
}

If you are working with Configs you may want a basic ConfigurationHandler class (Requires Reference Class)

Code:

public class ConfigurationHandler {

    public static Configuration configuration;

    public static void init(File configFile) {

        //create configuration object from the given file
        if (configuration == null)
        {
            configuration = new Configuration(configFile);
            loadConfiguration();
        }
    }

    @SubscribeEvent
    public void onConfigurationChangedEvent(ConfigChangedEvent.OnConfigChangedEvent event)
    {
        if (event.modID.equalsIgnoreCase(Reference.MOD_ID))
        {
            loadConfiguration();
        }
    }

    private static void loadConfiguration()
    {
        if (configuration.hasChanged())
        {
            configuration.save();
        }
    }
}

GameRegistryItems Class - Makes ItemRegistering less of a hassle = less typing contributed by @SoraZodia

Code:

/** Item registry class, have methods to make
* item registation in the GameRegistry a bit easier/less
* typing.
*
* THE init() METHOD MUST BE CALLED FOR IT TO WORK*/
public class GameRegistryItems {

    private static String MODID;
    private static CreativeTabs tabs;

    public static void init(String modID, CreativeTabs tab){
        MODID = modID;
        tabs = tab;
    }

    * extra stuff for you, just make sure your item object is initializated*/
    public static void registerItems(Item item, String itemName, String imageName){
        GameRegistry.registerItem(item, itemName, MODID)
        .setCreativeTab(tabs)
        .setUnlocalizedName(itemName)
        .setTextureName(MODID + ":"+ imageName);
    }
 
    /** This method is used when the item's name is the same
    * as its texture name. Helps reduce repetivite typing #lazy:P.
    * Please make sure your item object is initializated */
    public static void registerItems(Item item, String name){

        .setCreativeTab(tabs)
        .setUnlocalizedName(name)

GUI

GuiFactory Class - used for doing GUI stuff (I haven't used much, but I hear it is useful)

Code:

public class GuiFactory implements IModGuiFactory {

    @Override
    public void initialize(Minecraft minecraftInstance) {

    }

    @Override
    public Class<? extends GuiScreen> mainConfigGuiClass() {
        return ModGuiConfig.class;
    }

    @Override
    public Set<RuntimeOptionCategoryElement> runtimeGuiCategories() {
        return null;
    }

    @Override
    public RuntimeOptionGuiHandler getHandlerFor(RuntimeOptionCategoryElement element) {
        return null;
    }
}

ModGuiConfig Class - Again haven't used much, but I am told it is useful (Requires Reference/ConfigurarionHandler)

Code:

public class ModGuiConfig extends GuiConfig{

    public ModGuiConfig(GuiScreen guiScreen)
        {
            super(guiScreen,
                    new ConfigElement(ConfigurationHandler.configuration.getCategory(Configuration.CATEGORY_GENERAL)).getChildElements(),
                    Reference.MOD_ID,
                    false,
                    false,
                    GuiConfig.getAbridgedConfigPath(ConfigurationHandler.configuration.toString()));
        }

}

OreDictionary

OreHelper Class - useful when working with the ore dictionary contributed by @goldenapple and taken from Flaxbeard's Steam Power Mod (Requires LogHelper Class for full functionality)

Code:

public class OreHelper {
    public static boolean isItemThisOre(ItemStack item, String ore){
        for (int o : OreDictionary.getOreIDs(item)) {
            if (OreDictionary.getOreName(o).equals(ore)) {
                return true;
            }
        }
        return false;
    }
    //Requires the LogHelper class
    public static void dumpAllOres(){
        for (String l : OreDictionary.getOreNames()){
            LogHelper.info(l);
        }
    }
}

Look at the cofh string helper class. Or did you get it from there?

I've seen it, that's where I got the idea to incorporate it into my mod. I just didn't do all of it because I don't need it nor do I see a purpose for most of it.

I have mixed feelings about this thread. It has the potential to save a lot of time, but on the other hand, it has the potential to encourage mindless code copying. That being said, I could contribute my particle sequencing code. Give me a day or two to make it pretty.

True, but some tools are for sharing. I would never let anyone put say an energy storage block in the thread because people should learn how to do that. However, some things like the utility classes can be copied because they are for nothing more than that, utility.
