About this project
What does ConfigurationsBackport add?
ConfigurationsBackport
Brings back the 1.12.2 forge's Config annotation system to 1.8.9 using mixins.
Its documentation is present at: https://docs.minecraftforge.net/en/1.12.x/config/annotations/
How to use?
You would use the Config annotations exactly the same way as u did in 1.12.2.
But instead of net.minecraftforge.common.config.ConfigManager, its now my_life_is_bad.configurationsbackport.common.config.ConfigManager.
Example:
package my_life_is_bad.configurationsbackport;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.client.event.ConfigChangedEvent.OnConfigChangedEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.event.FMLConstructionEvent;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod.EventHandler;
import my_life_is_bad.configurationsbackport.common.config.ConfigManager;
import my_life_is_bad.configurationsbackport.common.config.Config;
@Mod(modid = ConfigurationsBackport.MODID, version = ConfigurationsBackport.VERSION)
public class ConfigurationsBackport {
public static final String MODID = "configurationsbackport";
public static final String VERSION = "1.1";
@Config(modid = MODID)
public static class Configuration {
@Config.Comment("String Entry: ")
public static String stringEntry = "I am a string :D";
@Config.Comment("Int Entry (Slider): ")
@Config.RangeInt(min = 1, max = 16)
@Config.SlidingOption()
public static int intSlider = 100;
@Config.Comment("Int Entry: ")
@Config.RangeInt(min = 1, max = 16)
public static int intEntry = 100;
@Config.Comment("Double Entry: ")
@Config.RangeDouble(min = 0.1D, max = 1.6D)
public static double doubleEntry = 0.1D;
@Config.Comment("Double Entry (Slider): ")
@Config.RangeDouble(min = 0.1D, max = 1.6D)
@Config.SlidingOption()
public static double doubleSlider = 0.1D;
}
@EventHandler
public void onFMLConstructionEvent(FMLConstructionEvent event) {
MinecraftForge.EVENT_BUS.register(this);
}
@SubscribeEvent
public void onConfigChangedEvent(OnConfigChangedEvent event) {
if (event.modID.equals(MODID)) {
ConfigManager.sync(MODID, Config.Type.INSTANCE);
}
}
