NovaViper

Not personally, but Jabelar has a tutorial on complex entity models with animation here. I can't really help you with your issues unless you give me something to work with. I need to see the entity, the loot table file, any custom loot table classes used in it (e.g. properties, conditions) and the loot table registration. The Source code is here

I know very little about rendering, I can't help you with animations. Use your EntityProperty in the properties section of an entity_properties conditional in your loot table JSON, like the on_fire property is used in the pig's loot table. Do you know anyone that can make animations? Also I still can't get the entity to drop items, not sure why it isn't dropping them

Hey Choonster, do you know anything about custom animations? I've been trying to figure out how to make such methods. Also, what do I do with the Entity Property I made?

Thanks! That worked!

Use ForgeVersion.getResult to get the CheckResult of the version check for the specified ModContainer . FMLCommonHandler#findContainerFor will return the ModContainer for the specified mod ID or instance. ICommand#execute has a MinecraftServer argument, pass this to your applyModifier method. Thanks! That fixed that error and got the version to display, I have another question though (Sorry for asking so many), I want the header of the help command to have gold seperators (---) and leave the rest of the text dark green. So far I got this: Code int l = Math.min((k + 1) * 7, list.size()); TextComponentTranslation textcomponenttranslation1 = ChatHelper.getChatComponentTranslation(TextFormatting.GOLD + "--- "+"commands.tetracraft:help.header" + TextFormatting.GOLD + " ---", new Object[] {Integer.valueOf(k + 1), Integer.valueOf(j + 1)}); textcomponenttranslation1.getStyle().setColor(TextFormatting.DARK_GREEN); sender.addChatMessage(textcomponenttranslation1); Lang File commands.tetracraft:help.header=Help page %d/%d (/tetracraft help <page>)

I suggest you set a breakpoint on line 155 of CommandAdmin , run the game in debug mode, use the command and then look at the debugger to see what's null . It looks like it's probably the MinecraftServer you get from FMLServerHandler . In 1.9, Minecraft is slowly moving away from MinecraftServer being a singleton since there's no static field in the class itself storing the instance and World has a getMinecraftServer method to get the world's server. For this reason, I suggest you use the MinecraftServer provided to the command rather than using FMLServerHandler (which still assumes there's only one MinecraftServer instance). I was trying to use MinecraftServer but I can't get the instance of it and yeah, thats what the error is talking about, the MineraftServer being null.

Also, how do I get the status of the Forge Version Checker just for my mod?

Hey Choonster, I got an issue with the admin commands, I get this error whenever I use the global optional parameter with the commands (it affects all of the mod tameable entities, which I make change that to all the entities in my mod instead of just the tameable ones): [18:34:58] [server thread/WARN]: Couldn't process command: 'admin gender female g' java.lang.NullPointerException at novaviper.tetracraft.common.command.CommandAdmin.applyModifier(CommandAdmin.java:155) ~[CommandAdmin.class:?] at novaviper.tetracraft.common.command.CommandAdmin.execute(CommandAdmin.java:94) ~[CommandAdmin.class:?] at net.minecraft.command.CommandHandler.tryExecute(CommandHandler.java:107) [CommandHandler.class:?] at net.minecraft.command.CommandHandler.executeCommand(CommandHandler.java:86) [CommandHandler.class:?] at novaviper.tetracraft.common.command.CommandTetraCraft.execute(CommandTetraCraft.java:88) [CommandTetraCraft.class:?] at net.minecraft.command.CommandHandler.tryExecute(CommandHandler.java:107) [CommandHandler.class:?] at net.minecraft.command.CommandHandler.executeCommand(CommandHandler.java:86) [CommandHandler.class:?] at net.minecraft.network.NetHandlerPlayServer.handleSlashCommand(NetHandlerPlayServer.java:957) [NetHandlerPlayServer.class:?] at net.minecraft.network.NetHandlerPlayServer.processChatMessage(NetHandlerPlayServer.java:933) [NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java:47) [CPacketChatMessage.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java: [CPacketChatMessage.class:?] at net.minecraft.network.PacketThreadUtil$1.run(PacketThreadUtil.java:15) [PacketThreadUtil$1.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [?:1.8.0_77] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [?:1.8.0_77] at net.minecraft.util.Util.runTask(Util.java:23) [util.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:738) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:683) [MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:155) [integratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:532) [MinecraftServer.class:?] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_77] [18:34:58] [Client thread/INFO]: [CHAT] An unknown error occurred while attempting to perform this command Source code for the command package novaviper.tetracraft.common.command;

Thanks Choonster!

I also don't want the help menu to sort the commands either. How do I fix that?

Thanks! I had to play around with the CommandBase.getListOfStringsMatchingLastWord(String[], String...) a little bit because it was a bit hard to understand with the ? : booleans but I did the if else and got it work. But I have one more question with the sub commands, how do I make the commands not sort? I want the Aliases to line up together like this: help, h, ?, version, v, admin, a , * Instead of this: help, a, v, h, admin, *, version, ?

I tested your implementation and it works exactly what I was think off, but I do have a question about it. How do I make help usage use a different header? The default ones says /help instead of /tetracraft help . Also, how do I make my admin command enter in the commands with the tab button?

Ah ok, so should I just leave everything in the handler I made blank and have the subcommands write something for each of the implements from ICommand ?

Should I make the class abstract? Also.. Should I override the exeuteCommand methods in CommandHandler and place the mod id here: if (rawCommand.startsWith("/")) <<<<< { rawCommand = rawCommand.substring(1); }

Basically I should make my own CommandHandler class that implements ICommand and ICommandManager correct?

Sorry for not responding in a while and I did get that error fixed, I have another question relating with commands. Is it possible to make sub-commands like /tetracraft admin tame and /tetracraft help ? And for the admin commands, only restrict them to the owner/admin while leaving the other ones like /tetracraft help to be used by everyone?

I'm getting an error now with the EntityProperty, it's on this issue on Github. The commit that's causing this error is linked to the issue also

Oh yeah, sorry about leaving that main package there, and I fixed that typo in the bow json and package. I did the EntityTamed like this package novaviper.tetracraft.common.entity.properties; import com.google.gson.JsonDeserializationContext; import com.google.gson.JsonElement; import com.google.gson.JsonPrimitive; import com.google.gson.JsonSerializationContext; import net.minecraft.entity.Entity; import net.minecraft.entity.passive.EntityTameable; import net.minecraft.util.JsonUtils; import net.minecraft.util.ResourceLocation; import net.minecraft.world.storage.loot.conditions.EntityHasScore; import net.minecraft.world.storage.loot.properties.EntityProperty; import novaviper.tetracraft.common.entity.EntityModTameable; import java.util.Random; /** * Created by NovaViper on 4/11/2016. * Class Purpose: Declares Entity Property for Tamed Mod Entities */ public class EntityTamed implements EntityProperty { private final boolean isTamed; public EntityTamed(boolean isTamedIn) { this.isTamed = isTamedIn; } public boolean testProperty(Random random, Entity entityIn) { if(entityIn instanceof EntityTameable){ EntityTameable entityTameable = (EntityTameable)entityIn; if(entityTameable.isTamed()){ return this.isTamed == true; }else{ return this.isTamed == false; } }else{ return this.isTamed == false; } } public static Serializer getSerializer(){ return new Serializer(); } public static class Serializer extends EntityProperty.Serializer<EntityTamed> { protected Serializer() { super(new ResourceLocation("is_tamed"), EntityTamed.class); } public JsonElement serialize(EntityTamed property, JsonSerializationContext serializationContext) { return new JsonPrimitive(Boolean.valueOf(property.isTamed)); } public EntityTamed deserialize(JsonElement element, JsonDeserializationContext deserializationContext) { return new EntityTamed(JsonUtils.getBoolean(element, "is_tamed")); } } } How do I acutally register this?

Hm, I having a bit of an issue with my loot table, the item I made isn't dropping. Also the contionus bow I made, not all of the textures is being shown, it just shows the first two but not the last one. The Source for this issue is in this commit

I'm not sure but while I was looking at the pig entity coding, I did find where I can acutally add in other conditions that isn't added to Loot Tables

Ok so I made the entity property class but I'm not sure on how to acutally register it for the entity to use (And test to see if it works)

It looks like you'll need to create an EntityProperty to test whether the entity has been tamed. You'll also need to create its EntityProperty.Serializer and register an instance of it with EntityPropertyManager.registerProperty . In your loot table, use the entity_properties condition with your property. How do I make Custom Entity Properties? I never made those before, mostly did datawatchers for certain properties like gender and evo stages.

See the wiki page. They're basically a more flexible replacement for ChestGenHooks / WeightedRandomChestContent that are also used for entity drops. Forge hasn't added any hooks for loot tables yet, but you can still register your own using the vanilla classes. You can see my loot table registration class here and a loot table here. Thanks! How would this work if I want to add a custom condition, like if the player has tamed the entity and it died?

Hey Choonster, I got another question, what in the world is Loot Tables? I want to make my entity drop something, but it wants a Loot Table
