Right, so now my entity spawns in the world and has a shadow, hitbox and sounds. However it's invisible. The console is saying that my entity can't be cast to EntityHorse, and i'm sure that I must be missing something in my RenderPegasus class. 2013-09-09 10:08:30 [iNFO] [sTDERR] java.lang.ClassCastException: RosarioMokaChan.RandomCraft.EntityPegasus cannot be cast to net.minecraft.entity.passive.EntityHorse 2013-09-09 10:08:30 [iNFO] [sTDERR] at RosarioMokaChan.RandomCraft.Pegasus.setLivingAnimations(Pegasus.java:362) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.entity.RendererLivingEntity.func_130000_a(RendererLivingEntity.java:153) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.entity.RenderLiving.doRenderLiving(RenderLiving.java:28) 2013-09-09 10:08:30 [iNFO] [sTDERR] at RosarioMokaChan.RandomCraft.RenderPegasus.renderPegasus(RenderPegasus.java:21) 2013-09-09 10:08:30 [iNFO] [sTDERR] at RosarioMokaChan.RandomCraft.RenderPegasus.doRender(RenderPegasus.java:31) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.entity.RenderManager.renderEntityWithPosYaw(RenderManager.java:312) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.entity.RenderManager.renderEntity(RenderManager.java:281) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.RenderGlobal.renderEntities(RenderGlobal.java:524) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.EntityRenderer.renderWorld(EntityRenderer.java:1160) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.renderer.EntityRenderer.updateCameraAndRender(EntityRenderer.java:1006) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:934) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:826) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.client.main.Main.main(Main.java:93) 2013-09-09 10:08:30 [iNFO] [sTDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 2013-09-09 10:08:30 [iNFO] [sTDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) 2013-09-09 10:08:30 [iNFO] [sTDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) 2013-09-09 10:08:30 [iNFO] [sTDERR] at java.lang.reflect.Method.invoke(Unknown Source) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.launchwrapper.Launch.launch(Launch.java:57) 2013-09-09 10:08:30 [iNFO] [sTDERR] at net.minecraft.launchwrapper.Launch.main(Launch.java:18)

Before I started anything to do with modding, I made sure to read a few java documents and do some exercises to learn some of the stuff needed, it's just abstract classes and a few other things weren't covered. Also making the class abstract was an alternative to importing net.minecraft.entity.EntityAgeable, which I was trying to avoid doing as I was trying to cut down on the amount of unnecessary imports.

To be honest, I just made it abstract because there was an error if I didn't do it. Not entirely sure what difference there is between the two though.

Ok, this is what I have in the EntityPegasus class. package RosarioMokaChan.RandomCraft; import RosarioMokaChan.RandomCraft.lib.ModBlocks; import net.minecraft.block.Block; import net.minecraft.block.StepSound; import net.minecraft.entity.EnumCreatureAttribute; import net.minecraft.entity.SharedMonsterAttributes; import net.minecraft.entity.ai.EntityAILookIdle; import net.minecraft.entity.ai.EntityAIPanic; import net.minecraft.entity.ai.EntityAISwimming; import net.minecraft.entity.ai.EntityAIWander; import net.minecraft.entity.ai.EntityAIWatchClosest; import net.minecraft.entity.passive.EntityAnimal; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.util.StatCollector; import net.minecraft.world.World; public abstract class EntityPegasus extends EntityAnimal { public EntityPegasus(World par1World) { super(par1World); this.setSize(1.4F, 1.6F); this.isImmuneToFire = true; this.getNavigator().setAvoidsWater(true); this.tasks.addTask(0, new EntityAISwimming(this)); this.tasks.addTask(1, new EntityAIPanic(this, 0.8D)); this.tasks.addTask(6, new EntityAIWander(this, 0.7D)); this.tasks.addTask(7, new EntityAIWatchClosest(this, EntityPlayer.class, 6.0F)); this.tasks.addTask(8, new EntityAILookIdle(this)); } protected boolean isAIEnabled(){ return true; } public int getMaxHealth() { return 15; } @Override protected String getLivingSound() { return "mob.horse.idle"; } @Override protected String getHurtSound() { return "mob.horse.hit"; } @Override protected String getDeathSound() { return "mob.horse.death"; } @Override protected float getSoundVolume() { return 0.4F; } protected int getDropItemId() { return Item.leather.itemID; } protected void playStepSound(int par1, int par2, int par3, int par4) { this.playSound("mob.horse.gallop", 0.15F, 1.0F); } protected void dropRareDrop(int par1){ switch (this.rand.nextInt(3)){ case 0: this.dropItem(ModBlocks.dragonWings.itemID, 1); break; } } public EnumCreatureAttribute getCreatureAttribute(){ return EnumCreatureAttribute.UNDEFINED; } }

I didn't use ModelHorse as I was going to make a new, similar model at a later date. I did this to get it setup for when I decided to do that. As for the constructors, do you think you could perhaps give a little hint as to what I need to do, as I thought that it was correct

So i'm making an entity which uses a similar model to that of a horse (so I copied everything from ModelHorse into a class which will be used by my entity and renamed everything so it would work), and I made a render class along with an entity class. In the main class I registered it and made the spawn egg, but whenever I try to spawn it into the world I just get an error message in the console.

So by using GoToLink's suggestion, it all works . Thanks Kakarotvg and GotoLink, I couldn't have done it without you .

Ok, i'll try that in a minute after I recreate my Strings class.

That doesn't seem to help i'm afraid. I guess minecraft just doesn't want me to make a config file lol

After putting in: Configuration config = new Configuration(event.getSuggestedConfigurationFile()); config.load(); BlockIds.createConfigfile(config); config.save(); instead of ConfigurationHandler.init(new File(event.getModConfigurationDirectory().getAbsolutePath()+ File.separator + ModInfo.ID + File.separator + ModInfo.ID + ".cfg")); After commenting out all of the ConfigurationHandler class it still refuses to startup, producing the same error report.

I've tried doing it in a similar way to what you described, but it still doesn't feel like working. I commented out some lines in the BlockIds class and in the ConfigurationHandler so I could try it this way as shown below: package RosarioMokaChan.RandomCraft.lib; import net.minecraftforge.common.Configuration; public class BlockIds { public static String blockids = "Block IDs"; //public static final int PLUTONIUMBLOCK_ID_DEFAULT = 3000; public static int PLUTONIUMBLOCK_ID; //public static final int PLUTONIUMORE_ID_DEFAULT = 3001; public static int PLUTONIUMORE_ID; //public static final int RADIUMBLOCK_ID_DEFAULT = 3002; public static int RADIUMBLOCK_ID; //public static final int RADIUMORE_ID_DEFAULT = 3003; public static int RADIUMORE_ID; //public static final int MOONSTONE_ID_DEFAULT = 3004; public static int MOONSTONE_ID; public static void createConfigfile(Configuration config) { // block ids PLUTONIUMBLOCK_ID = config.get(blockids, "plutoniumBlock", 3000).getInt(); PLUTONIUMORE_ID = config.get(blockids, "plutoniumOre", 3001).getInt(); RADIUMBLOCK_ID = config.get(blockids, "radiumBlock", 3002).getInt(); RADIUMORE_ID = config.get(blockids, "radiumOre", 3003).getInt(); MOONSTONE_ID = config.get(blockids, "moonstone", 3004).getInt(); } }

In my BlockIds class I have the two blocks as having ids 3000 and 3001 as shown here: public class BlockIds { public static final int PLUTONIUMBLOCK_ID_DEFAULT = 3000; public static int PLUTONIUMBLOCK_ID; public static final int PLUTONIUMORE_ID_DEFAULT = 3001; public static int PLUTONIUMORE_ID; public static final int RADIUMBLOCK_ID_DEFAULT = 3002; public static int RADIUMBLOCK_ID; public static final int RADIUMORE_ID_DEFAULT = 3003; public static int RADIUMORE_ID; public static final int MOONSTONE_ID_DEFAULT = 3004; public static int MOONSTONE_ID; } Then applied to the block in the main class here: public final static Block plutoniumBlock = new PlutoniumBlock(BlockIds.PLUTONIUMBLOCK_ID, Material.iron); public final static Block plutoniumOre = new PlutoniumOre(BlockIds.PLUTONIUMORE_ID, Material.rock); So i'm not sure how i'm getting the ids messed up.

Sorry, but i'm not quite getting what I need to do with config.getItem/Block (I'm kind of new to the whole config thing ).

If you mean the bit from the config handler, then here ya go: package RosarioMokaChan.RandomCraft; import java.io.File; import java.util.logging.Level; import cpw.mods.fml.common.FMLLog; import RosarioMokaChan.RandomCraft.lib.BlockIds; import RosarioMokaChan.RandomCraft.lib.ItemIds; import RosarioMokaChan.RandomCraft.lib.ModInfo; import RosarioMokaChan.RandomCraft.lib.Strings; import net.minecraftforge.common.Configuration; public class ConfigurationHandler { static Configuration config = new Configuration(); public static void init(File file){ config = new Configuration(file); try{ config.load(); BlockIds.PLUTONIUMBLOCK_ID = config.get(config.CATEGORY_BLOCK, Strings.PLUTONIUMBLOCK_NAME, BlockIds.PLUTONIUMBLOCK_ID_DEFAULT).getInt(BlockIds.PLUTONIUMBLOCK_ID_DEFAULT); BlockIds.PLUTONIUMORE_ID = config.get(config.CATEGORY_BLOCK, Strings.PLUTONIUMORE_NAME, BlockIds.PLUTONIUMORE_ID_DEFAULT).getInt(BlockIds.PLUTONIUMORE_ID_DEFAULT); BlockIds.RADIUMBLOCK_ID = config.get(config.CATEGORY_BLOCK, Strings.RADIUMBLOCK_NAME, BlockIds.RADIUMBLOCK_ID_DEFAULT).getInt(BlockIds.RADIUMBLOCK_ID_DEFAULT); BlockIds.RADIUMORE_ID = config.get(config.CATEGORY_BLOCK, Strings.RADIUMORE_NAME, BlockIds.RADIUMORE_ID_DEFAULT).getInt(BlockIds.RADIUMORE_ID_DEFAULT); BlockIds.MOONSTONE_ID = config.get(config.CATEGORY_BLOCK, Strings.MOONSTONE_NAME, BlockIds.MOONSTONE_ID_DEFAULT).getInt(BlockIds.MOONSTONE_ID_DEFAULT); ItemIds.ENDERHATCHER_ID = config.get(config.CATEGORY_ITEM, Strings.ENDERHATCHER_NAME, ItemIds.ENDERHATCHER_ID_DEFAULT).getInt(ItemIds.ENDERHATCHER_ID_DEFAULT); ItemIds.PLUTONIUMINGOT_ID = config.get(config.CATEGORY_ITEM, Strings.ENDERHATCHER_NAME, ItemIds.ENDERHATCHER_ID_DEFAULT).getInt(ItemIds.ENDERHATCHER_ID_DEFAULT); ItemIds.RADIUMINGOT_ID = config.get(config.CATEGORY_ITEM, Strings.ENDERHATCHER_NAME, ItemIds.ENDERHATCHER_ID_DEFAULT).getInt(ItemIds.ENDERHATCHER_ID_DEFAULT); ItemIds.MOONSTONEDUST_ID = config.get(config.CATEGORY_ITEM, Strings.ENDERHATCHER_NAME, ItemIds.ENDERHATCHER_ID_DEFAULT).getInt(ItemIds.ENDERHATCHER_ID_DEFAULT); ItemIds.DRAGONWINGS_ID = config.get(config.CATEGORY_ITEM, Strings.ENDERHATCHER_NAME, ItemIds.ENDERHATCHER_ID_DEFAULT).getInt(ItemIds.ENDERHATCHER_ID_DEFAULT); ItemIds.DIAMONDHORSECHEST_ID = config.get(config.CATEGORY_ITEM, Strings.DIAMONDHORSECHEST_NAME, ItemIds.DIAMONDHORSECHEST_ID_DEFAULT).getInt(ItemIds.DIAMONDHORSECHEST_ID_DEFAULT); ItemIds.DIAMONDHORSEHELM_ID = config.get(config.CATEGORY_ITEM, Strings.DIAMONDHORSEHELM_NAME, ItemIds.DIAMONDHORSEHELM_ID_DEFAULT).getInt(ItemIds.DIAMONDHORSEHELM_ID_DEFAULT); ItemIds.GOLDHORSECHEST_ID = config.get(config.CATEGORY_ITEM, Strings.GOLDHORSECHEST_NAME, ItemIds.GOLDHORSECHEST_ID_DEFAULT).getInt(ItemIds.GOLDHORSECHEST_ID_DEFAULT); ItemIds.GOLDHORSEHELM_ID = config.get(config.CATEGORY_ITEM, Strings.GOLDHORSEHELM_NAME, ItemIds.GOLDHORSEHELM_ID_DEFAULT).getInt(ItemIds.GOLDHORSEHELM_ID_DEFAULT); ItemIds.IRONHORSECHEST_ID = config.get(config.CATEGORY_ITEM, Strings.IRONHORSECHEST_NAME, ItemIds.IRONHORSECHEST_ID_DEFAULT).getInt(ItemIds.IRONHORSECHEST_ID_DEFAULT); ItemIds.IRONHORSEHELM_ID = config.get(config.CATEGORY_ITEM, Strings.IRONHORSEHELM_NAME, ItemIds.IRONHORSEHELM_ID_DEFAULT).getInt(ItemIds.IRONHORSEHELM_ID_DEFAULT); } catch(Exception e){ FMLLog.log(Level.SEVERE, e, ModInfo.ID + " has trouble loading the config"); } finally{ config.save(); } } }

Hi, I recently made a configuration file for my mod so users can change the item ids of blocks and items (as expected), but when I test it in eclipse it crashes. I read through the error report and I think it's saying that there's a conflict between two blocks (plutoniumblock and plutoniumore). Although by searching all throughout my code, I can't seem to find any conflicts. Any opinions on a fix would be greatly appreciated.

Haha, wow. I thought I didn't need that bit as well . That sorted the problem immediately, thanks.

After deciding to recompile and reobf my mod to test it, it keeps on crashing the launcher at the mojang screen. By seeing ClassNotFoundException in the crash report, I thought that perhaps I had done my common and client proxies wrong or something, but I can't figure out what I did wrong at all. Here's a copy of the crash report: ---- Minecraft Crash Report ---- // Surprise! Haha. Well, this is awkward.
