Have you registered the entities? You should register them with EntityRegistry.registerModEntity and EntityList.addMapping

Hello, I'm making a messenger mod for the client. The person sending/receiving the message are identified by their Mojang UUID. However, I need to find a way to convert the UUID to the person's username to be shown on the GUI. This is client-side, so I'd like to do it without the MinecraftSessionService in the MinecraftServer. I've tried making a query to https://sessionserver.mojang.com/session/minecraft/profile/ and converting it to a GameProfile using Gson. Doesn't work. I've tried using a HttpProfileRepository to get it. It takes to long to respond, usually fails, and is for converting the username to a UUID. It is really important that I do this. It would be easier to use usernames as IDs, but I'd like to be ready for the name changes Here's my user class: package assets.mcmessenger.client.messenger; import java.awt.image.BufferedImage; import java.net.URL; import java.util.UUID; import javax.imageio.ImageIO; import net.minecraft.client.Minecraft; import net.minecraft.client.renderer.texture.DynamicTexture; import net.minecraft.util.ResourceLocation; import assets.mcmessenger.client.messenger.util.GameProfileCreator; import com.mojang.authlib.GameProfile; public class User { private static final String faceFetchUrl = "http://cravatar.eu/helmavatar/%s"; private String uuid; private String name; private ResourceLocation face; public User(String uuid) { this.uuid = uuid; if(this.uuid.equals(Minecraft.getMinecraft().getSession().getUsername())) { this.setName(Minecraft.getMinecraft().getSession().getUsername()); } else { try { GameProfile profile = GameProfileCreator.createGameProfileFromUUID(uuid); setName(profile.getName()); } catch(Exception e) { setName(e.toString()); } } } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public UUID getUUID() { return UUID.fromString(uuid); } public ResourceLocation getFace() { if(this.face == null) { BufferedImage image = null; try { image = ImageIO.read(new URL(String.format(faceFetchUrl, getName()))); } catch(Exception e) { e.printStackTrace(); } DynamicTexture texture = new DynamicTexture(0, 0); if(image != null) { texture = new DynamicTexture(image); } this.face = Minecraft.getMinecraft().getTextureManager().getDynamicTextureLocation("face_" + getName(), texture); } return this.face; } public boolean equals(User user) { return user.uuid == this.uuid; } } Here's my profile creator: package assets.mcmessenger.client.messenger.util; import java.io.InputStreamReader; import java.io.Reader; import java.net.URL; import java.util.UUID; import org.apache.commons.io.IOUtils; import com.google.gson.Gson; import com.google.gson.GsonBuilder; import com.google.gson.stream.JsonReader; import com.mojang.api.profiles.Profile; import com.mojang.authlib.GameProfile; public class GameProfileCreator { private static final String fetchIdUrl = "https://api.mojang.com/users/profiles/minecraft/%s?at=%s"; private static final String fetchNameUrl = "https://sessionserver.mojang.com/session/minecraft/profile/%s"; public static Profile createGameProfileFromUsername(String username) { try { Gson gson = new GsonBuilder().setPrettyPrinting().create(); String url = String.format(fetchIdUrl, username, String.valueOf(System.currentTimeMillis())); JsonReader reader = new JsonReader(new InputStreamReader(new URL(url).openStream())); reader.setLenient(true); return (Profile)gson.fromJson(reader, Profile.class); } catch(Exception e) { e.printStackTrace(); } Profile profile = new Profile(); profile.setName(username); return profile; } public static Profile createGameProfileFromUUID(String uuid) { try { Gson gson = new GsonBuilder().setPrettyPrinting().create(); String url = String.format(fetchNameUrl, uuid); JsonReader reader = new JsonReader(new InputStreamReader(new URL(url).openStream())); reader.setLenient(true); return (Profile)gson.fromJson(reader, Profile.class); } catch(Exception e) { e.printStackTrace(); } Profile profile = new Profile(); profile.setId(uuid); return profile; } } If anyone can help, I would be SO grateful! Thank you very much for your time. - Romejanic

If you wanted to cheat it without server compatibility, you would use Minecraft.getMinecraft().thePlayer. Otherwise, you need to send a packet to the server with the username, obtained by using Minecraft.getMinecraft().thePlayer.getCommandSenderName(). The packet will locate a player by their username (matching it to the name in the packet) and move the player like that. Here's a code example: Packet Class public class PacketMovePlayer implements IMessage { public String username; public PacketMovePlayer(String username) { this.username = username; } public PacketMovePlayer() {} @Override public void toBytes(ByteBuf buf) { ByteBufUtils.writeUTF8String(buf, username); } @Override public void fromBytes(ByteBuf buf) { this.username = ByteBufUtils.readUTF8String(buf); } public class Handler implements IMessageHandler<PacketMovePlayer, IMessage> { @Override public IMessage onMessage(PacketMovePlayer message, MessageContext ctx) { for(Object o : MinecraftServer().getServer().getConfigurationManager().playerEntityList) { if(((EntityPlayer)o).getCommandSenderName().equals(message.username)) { // move player return null; } } return null; } } } Mod Class public static SimpleNetworkWrapper network; @EventHandler public void preInit(FMLPreInitializationEvent event) { // other pre-init stuff network = NetworkRegistry.INSTANCE.newSimpleChannel("your_mod_id"); network.registerMessage(PacketMovePlayer.Handler.class, PacketMovePlayer.class, 0, Side.CLIENT); } Teleport Code YourMod.network.sendToServer(new PacketMovePlayer(Minecraft.getMinecraft().thePlayer.getCommandSenderName())); Hope that helps! Just a side note, if you are doing the teleport code in an item, just reference the EntityPlayer parameter in your onItemRightClick method! - Romejanic

Yeah, if you are doing client to server packets, ALWAYS send the packets. Since 1.3, singleplayer runs a server as well to support LAN worlds. - Romejanic

Hye everyone, I am making a mod which replaces the Tall Grass/Dead Bush/Flower/etc rendering to realistic 3D models. I am using the advanced model loader to lead and render the models, but I cannot do anything in the block renderer other than using the RenderBlocks field or drawing it myself with the GL11.glVertex() functions. The tessellator will says it is already drawing when you call tessellator.startDrawing() (which the OBJ model does), and it says it is not drawing when I call tessellator.draw() to reset it. (I also tried to use the vanilla models by drawing ModelPig, and that didn't work either, same problem) Here's the crash report: ---- Minecraft Crash Report ---- // Hey, that tickles! Hehehe!

Yes, I've used that but the problem is that: 1) It's range is too short, it needs to stretch on infinitely 2) It does not change to null if it moves out of range I'll have a look at the Minecraft class and see how it defines objectMouseOver. Thanks for your help. - Romejanic

Hey guys! In my gun mod, I have created crosshairs which expand to indicate the bullet spread (like Call of Duty), but I want them to turn red when you look at an entity, to show that you will hit them. I've done the colouring, but there's one problem. The raycasting solution i found on the internet doesn't count for entities. I tried to modify the code with bits from EntityThrowable to make it work, but I doesn't work. Here's the current code: public static MovingObjectPosition raycastBlocksAndEntities(EntityPlayer player, World world) { float f = 1.0F; float f1 = player.prevRotationPitch + (player.rotationPitch - player.prevRotationPitch) * f; float f2 = player.prevRotationYaw + (player.rotationYaw - player.prevRotationYaw) * f; double d = player.prevPosX + (player.posX - player.prevPosX) * (double)f; double d1 = (player.prevPosY + (player.posY - player.prevPosY) * (double)f + 1.6200000000000001D) - (double)player.yOffset; double d2 = player.prevPosZ + (player.posZ - player.prevPosZ) * (double)f; Vec3 vec3d = Vec3.createVectorHelper(d, d1, d2); float f3 = MathHelper.cos(-f2 * 0.01745329F - 3.141593F); float f4 = MathHelper.sin(-f2 * 0.01745329F - 3.141593F); float f5 = -MathHelper.cos(-f1 * 0.01745329F); float f6 = MathHelper.sin(-f1 * 0.01745329F); float f7 = f4 * f5; float f8 = f6; float f9 = f3 * f5; double d3 = 5000D; Vec3 vec3d1 = vec3d.addVector((double)f7 * d3, (double)f8 * d3, (double)f9 * d3); MovingObjectPosition movingobjectposition = world.rayTraceBlocks(vec3d, vec3d1, false); return movingobjectposition; } Here's my modified code (which doesn't work): public static MovingObjectPosition raycastBlocksAndEntities(EntityPlayer player, World world) { float f = 1.0F; float f1 = player.prevRotationPitch + (player.rotationPitch - player.prevRotationPitch) * f; float f2 = player.prevRotationYaw + (player.rotationYaw - player.prevRotationYaw) * f; double d = player.prevPosX + (player.posX - player.prevPosX) * (double)f; double d1 = (player.prevPosY + (player.posY - player.prevPosY) * (double)f + 1.6200000000000001D) - (double)player.yOffset; double d2 = player.prevPosZ + (player.posZ - player.prevPosZ) * (double)f; Vec3 vec3d = Vec3.createVectorHelper(d, d1, d2); float f3 = MathHelper.cos(-f2 * 0.01745329F - 3.141593F); float f4 = MathHelper.sin(-f2 * 0.01745329F - 3.141593F); float f5 = -MathHelper.cos(-f1 * 0.01745329F); float f6 = MathHelper.sin(-f1 * 0.01745329F); float f7 = f4 * f5; float f8 = f6; float f9 = f3 * f5; double d3 = 5000D; Vec3 vec3d1 = vec3d.addVector((double)f7 * d3, (double)f8 * d3, (double)f9 * d3); MovingObjectPosition movingobjectposition = world.rayTraceBlocks(vec3d, vec3d1, false); if(movingobjectposition != null) { Vec3 vec3 = Vec3.createVectorHelper(player.posX, player.posY, player.posZ); Vec3 vec31 = Vec3.createVectorHelper(movingobjectposition.hitVec.xCoord, movingobjectposition.hitVec.yCoord, movingobjectposition.hitVec.zCoord);; if (!player.worldObj.isRemote) { Entity entity = null; List list = player.worldObj.getEntitiesWithinAABBExcludingEntity(player, AxisAlignedBB.getBoundingBox(vec31.xCoord - 1d, vec31.yCoord - 1d, vec31.zCoord - 1d, vec31.xCoord + 1d, vec31.yCoord + 1d, vec31.zCoord + 1d)); double d0 = 0.3D; EntityLivingBase entitylivingbase = player; System.out.println(list); for (int j = 0; j < list.size(); ++j) { Entity entity1 = (Entity)list.get(j); if (entity1.canBeCollidedWith() && !entity1.isEntityEqual(entitylivingbase)) { if(entity1.getDistance(vec31.xCoord, vec31.yCoord, vec31.zCoord) <= d0) { entity = entity1; break; } } } if (entity != null) { return new MovingObjectPosition(entity); } } } return movingobjectposition; } Does anyone have any ideas? Thanks for your help. - Romejanic

Thank you so much! Works perfectly! Been looking for a solution to this for ages - Romejanic

Who said you can't have capes? Add this line to the render code: if(event.entityPlayer instanceof AbstractClientPlayer) { ((AbstractClientPlayer) event.entityPlayer).func_152121_a(Type.CAPE, new ResourceLocation("yourmod:whatever/the/path/is.png")); } Cheers! - Romejanic

What do you mean by 3D model item? Like a ItemRenderer (custom model on item in first person, third person, inventory and dropped entity)? - Romejanic

Hey everyone. I am trying to make a vehicle. A car to be exact. It works pretty smoothly, but the only problem is that I need to get it hopping up blocks. They way I want it to work is that if you collide with a block, and there is a nonsolid/air block above it, it moves up onto the block. If there is however, a solid block above it, it will take crash damage. Any ideas?

Instead of calling the setVelocity method (which is client-side only), change the motionX/motionY/motionZ directly. Example: player.motionX += 0d; player.motionY += 1d; player.motionZ += 0d; Hope this helps! - Romejanic

Item and block textures are icons, because they are stitched onto a spritesheet at startup, reducing the required memory for texture storage. The Tessellator class uses U and V coordinates to render a texture. The U and V usually translate to the X and Y coordinates of the item texture on the spritesheet. If you are rendering a texture directly with Minecraft.renderEngine.bind(ResourceLocation), the U and V is usually 0 and 1, with 0 being, well 0, and 1 being the width/height of the texture. So the item's U and V is usually between those 2 numbers. If you are using ItemRenderer, you don't need to worry about these methods. You only need to know about them if you are using the Tessellator directly. It's the same as the glTexCoords2() in OpenGL (which Minecraft uses for rendering)

Haha sorry, I posted that when I was still using 1.6.4 Just use the item without a constructor. That int was the old itemID, which doesn't exist in 1.7

Basically me and my friend copied the code back over from the boat and we were very picky about what code to add and remove. It seems pretty stable now. Thanks anyway, just need help getting it move up blocks. Any ideas?

Hey everyone! I'm trying to make a vehicle. I've got it moving and the controls work, but it keeps jolting up and down. Sometimes it will stop, before promptly teleporting back to it's original position and starting again. Does anyone have any ideas?

You can also use the ByteBufUtils class which has some amazing stuff, like ItemStacks and NBT Compounds!

Here is an example item with the code: package test; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.util.ChunkCoordinates; import net.minecraft.world.World; public class ItemTest extends Item { public ItemTest(int par1) { super(par1); } /** * This is called when the player right-clicks with the item in hand * This is triggered anytime the player right-clicks */ public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) { ChunkCoordinates spawn = par3EntityPlayer.getBedLocation(); if(spawn == null) { spawn = par3EntityPlayer.worldObj.getSpawnPoint(); } par3EntityPlayer.setPosition(spawn.posX, spawn.posY, spawn.posZ); return par1ItemStack; } /** * This is called when the player right-clicks with the item in hand * This is triggered only when a block is right-clicked */ public boolean onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10) { ChunkCoordinates spawn = par2EntityPlayer.getBedLocation(); if(spawn == null) { spawn = par2EntityPlayer.worldObj.getSpawnPoint(); } par2EntityPlayer.setPosition(spawn.posX, spawn.posY, spawn.posZ); return true; } }

Using the command would disrupt the gameplay (if they want to use that command) and it would be a little inconvenient. Instead, you can use this: ChunkCoordinates spawn = player.getBedLocation(); if(spawn == null) { spawn = player.worldObj.getSpawnPoint(); } player.setPosition(spawn.posX, spawn.posY, spawn.posZ); It will check if the player has slept in a bed. If they have, teleport them to the bed. Otherwise, teleport the to the world spawn.

Hey everyone! I am adding custom achievements to a mod. I have created the achievements and they are unlocking. But there is a small problem... First of all, the game starts up perfectly. If I unlock the achievement and restart the game, it crashes on startup. 2014-04-23 19:10:41 [iNFO] [sTDOUT] ---- Minecraft Crash Report ---- 2014-04-23 19:10:41 [iNFO] [sTDOUT] // Hi.

I downloaded the latest forge source for 1.6.4 and set it up but it's still crashing! It's the same errors! Any ideas?

I cd'd to the forge folder and typed python install.py. The workspace already had the assets, versions and mcl in it

Thanks - Romejanic

For making a GUI, make a new class extending the GuiScreen class. You can look in the net.minecraft.client.gui packages for help. When it comes to displaying it, you just say Minecraft.getMinecraft().displayGuiScreen(new MyGuiScreen()); But make sure this code is only executed in a @SideOnly(Side.CLIENT) method or inside a if(FMLCommonHandler.instance().getEffectiveSide == Side.CLIENT) statement to stop your mod crashing on servers. Hope I helped! Romejanic

You can't be serious! I won't update my mods until that is fixed
