[Solved] [1.12] AI behaving wierdly


felinoid

Recommended Posts

I wanted to make my own textures for horses, so I made my own mob that is basically a horse but with the texture code changed. The trouble is, it's not behaving exactly like vanilla horses. Vanilla horses walk for at least a few steps at a time, whereas mine will walk a step, stop, and walk some more. This doesn't sound like much, I know, but it really looks silly. I'm really confused as to why there's any difference, though. Vanilla horses inherit from AbstractHorse, which sets the AI, and then don't change the AI at all. Mine too inherit from AbstractHorse and don't change the AI. How come they're different?

 

Here's my horse class:

Main mod class, HorseColors.java:


package felinoid.horse_colors;

import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.event.*;
import net.minecraft.block.Block;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.SidedProxy;


@Mod(modid = HorseColors.MODID, name = HorseColors.NAME, version = HorseColors.VERSION)

public class HorseColors
{
    public static final String NAME = "Realistic Horse Colors";
    public static final String MODID = "horse_colors";
    public static final String VERSION = "1.12.2-1.0.0";


    @SidedProxy(clientSide="felinoid.horse_colors.ClientProxy",  serverSide="felinoid.horse_colors.CommonProxy")
    public static CommonProxy proxy;
    
    @Mod.Instance("horse_colors")
    public static HorseColors instance;
    
    @Mod.EventHandler
    public void preInit(final FMLPreInitializationEvent event) 
    {
        MinecraftForge.EVENT_BUS.register(ModEntities.class);
    }
    
    @Mod.EventHandler
    public void init(final FMLInitializationEvent event) 
    {
        proxy.registerRenderers();
    }
    
    @Mod.EventHandler
    public void postInit(final FMLPostInitializationEvent event) {}
}

 

ClientProxy.java:


package felinoid.horse_colors;

import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.client.registry.RenderingRegistry;
import net.minecraftforge.fml.relauncher.SideOnly;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.entity.Entity;
import net.minecraft.client.model.ModelHorse;

public class ClientProxy extends CommonProxy {

    @SideOnly(Side.CLIENT)
    @Override
    public void registerRenderers() {
        RenderHorseFelinoid horseRender = new RenderHorseFelinoid(Minecraft.getMinecraft().getRenderManager());
        RenderingRegistry.registerEntityRenderingHandler(EntityHorseFelinoid.class, horseRender);
	}
}

 

CommonProxy.java:


package felinoid.horse_colors;

// Highly unimpressive class.
public class CommonProxy
{
    public void registerRenderers() {}
}

 

 

Any help figuring this out would be greatly appreciated!

 

Edit: Found the solution here. Turns out my update frequency was way too high.
