I did some more testing and I found the point in vanilla where the bug was fixed. The bug exists up to snapshot 19w05a, but in 19w06a, it seems to be fixed. I can't seem to find the exact bug that caused it (https://minecraft.gamepedia.com/19w06a#Fixes), so does anyone know if there is a way to find out and maybe implement that in my own code?

Even if the mod is for single player only, the position of an entity shouldn't be abused for cosmetic (rendering) purposes; the position of an entity does a lot more than "keeping the entity visible", and messing with it can break other things.

Good point, I think I'll just stick with multiple parts. Are IEntityMultiPart and MultiPartEntityPart (the ones used in EntityDragon) the best for this or is there a better method?

April 3, 2019

Could a possible solution be to constantly move the origin of the entity so that it's always in the frustum and simply translate the model so it looks like it's staying in the same place?

AFAIK this s due to the chunk(s) the entity is in is being culled; there is not much you can do about it.

I know this is the problem, but wouldn't fixing the hitbox size put the entity in more chunks so it wouldn't be culled? Or can entities only be tied to a single chunk?

If there isn't a fix for the hitbox/culling, I'll just go with multiple parts.

Also, I saw an issue on Advanced Rocketry for the same problem, and it said there was a pull request that fixed it, but the same issue seems to be happening here.

April 2, 2019

I have created an entity that is ~70 blocks tall and ~6 blocks wide, and I have set its hitbox so that when I press F3 + B, it fills up the entire entity. However, I can only interact (hit) the bottom ~4 blocks, and when I look too far up, the entity disappears entirely (I think this is because the subchunk in which those ~4 blocks are in is not loaded). I have noticed the same issue with the vanilla giant mob, which also disappears at certain angles and also has a bugged hitbox. I have seen a few threads about this same problem, but none of them had a solution for this problem.

Entity hitbox:

Same view but a bit higher up:

I tried setting ignoreFrustumCheck to true, as well as forcing some render methods to always return true for "should render", but none of that worked. The source code can be found here. The entity in question is here.

Any ideas?

Entities are tied to the chunk. So if the chunk it's in is culled there is nothing you can do to make the entity render.

You need to split your entity into multiple parts.

I have a similar problem, but my entity is really tall rather than (I'm assuming) really wide. Whenever I look too high, it completely disappears. I tried setting ignoreFrustumCheck to true, and I also tried overriding methods like shouldRender to always return true. I'm pretty sure it's not a problem with chunks. However, nothing has worked. Is there any way to fix this that doesn't involve creating multiple entities?

Also, this might be related - the hitbox from F3 + B goes all the way to the top of the rocket, but only the bottom 4-ish blocks can actually be hit.

Thanks for the reply, moved forward but getting a different error now.

I ended up using the Shadow plugin to package and relocate the dependency and just told ForgeGradle to reobfuscate the resulting JAR.

Now getting:

The updated build.gradle shows how I used your code.

Further thoughts?

@Choonster

I tried shading again and I am now getting:

> Could not find method srgExtra() for arguments [PK: org/apache/commons/logging org/mobycraft/org/apache/commons/logging] on root project 'mobycraft.forge'.

I have already looked at http://www.minecraftforge.net/forum/index.php?topic=37004.0 and the syntax seems to be fine in my case.

Here is how the minecraft section of my build.gradle file looks like:

minecraft {
    version = "1.8.9-11.15.1.1762"
    runDir = "run"
    
    // the mappings can be changed at any time, and must be in the following format.
    // snapshot_YYYYMMDD   snapshot are built nightly.
    // stable_#            stables are built at the discretion of the MCP team.
    // Use non-default mappings at your own risk. they may not allways work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = "stable_20"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.

    srgExtra "PK: org/apache/commons/logging org/mobycraft/org/apache/commons/logging"
}

Any idea what could be wrong?

Thanks for all the quick resposnses again!

@Shadowfacts: I tried out the two lines you posted in my build.gradle file, and I got the same error as before (NoSuchMethodError). I didn't try out the second code sample because I am not using CurseGradle.

I have a project that uses the shadow plugin, and I had to do it a bit of messing around but I got it to work. My build.gradle file is here but the key point is these two lines:
reobf { shadowJar { mappingType = "SEARGE" } }
tasks.reobfShadowJar.mustRunAfter shadowJar
This tells ForgeGradle to add a reobfShadowJar task that reobfuscates the shadowJar and has it automatically run after the shadowJar task. Depending on your configuration, you may need to run reobfShadowJar manually (e.g. run
gradlew shadowJar reobfShadowJar
). If you use CurseGradle you'll need to add something like this (but with 000000 replaced with your project id):
afterEvaluate {
tasks.curseforge240995.dependsOn reobfShadowJar
}

@Choonster: After trying out shadowfacts' code, I switched to the "shade" plugin and used that instead. This time I got a different error:

Thanks for the quick replies!

When I am building my mod, I first do "./gradlew build", then "./gradlew shadowJar" to bundle the mod with the other JARs. Correct me if I'm wrong, but that should reobfuscate the mod.

It looks like the
shadowJar
task uses the compiled output from the
main
SourceSet
, but ForgeGradle handles reobfuscation separately (it assembles the JAR and then reobfuscates that).

It may be easier to use the shading method described here than trying to integrate the shadow plugin with ForgeGradle.

@UberAffe: The proxy example is helpful but isn't what I am looking for. Draco18s said that I was running client-only code on a server, which implies that I should use a server-only proxy, but your example is for client-side proxies.

Proxy is used do separate registration code that is meant for the Physical client(logical client and logical server) and Physical server(logical server only)

In your main mod file you use
@SidedProxy(clientSide = Refs.CLIENTPROXY, serverSide = Refs.SERVERPROXY)
    public static CommonProxy proxy;
CLIENTPROXY and SERVERPROXY are strings that would be equal to an import line.
if an import would look like
import modid.ClientProxy;

@SidedProxy(clientSide = "modid.ClientProxy"
your clientproxy class should extend common proxy.

Your mod file will now have this:
       @SidedProxy(clientSide = Refs.CLIENTPROXY, serverSide = Refs.SERVERPROXY)
       public static CommonProxy proxy;

       @EventHandler
       public void preInit (FMLPreInitializationEvent event){
	proxy.preInit();
}

@EventHandler
        public void init (FMLInitializationEvent event){
	proxy.init();
}

@EventHandler
        public void postInit (FMLPostInitializationEvent event){
                proxy.postInit();
}
the majority of your registration will go in CommonProxy, and any client specific stuff (KeyBindings, GUI's, etc) will go in ClientProxy.

The mod has a bunch of other JARs bundled with it into a shadow JAR. I use the shadowJar plugin in the build.gradle file to make it. I put the shadow JAR into the mods folder and got the above error.

The next thing I tried was to convert the shadow JAR to a ZIP file and remove the mod files. I placed the mod files into a separate JAR, which I will call the mod JAR. I called the JAR with everything but the mod files as the dependency JAR. I tried putting both the mod JAR and the dependency JAR into the mods folder, but that gave me a different error - the mod JAR was not able to find the classes from the dependency JAR.

Any suggestions on how to debug this further?

Hi everyone,

I am currently developing a mod that requires a lot of external libraries in the form of JAR files (around 15 or so libraries). I can run the project fine from Eclipse, but when I try to do "./gradlew build", it gives me a BUILD FAILED because it is unable to compile the references to the outside libraries. I tried searching up the problem and putting dependencies in the build.gradle file, but even the help links inside the file were not helpful. Can anyone please help me out?

Thanks for the tip! I had to mess around with it a bit and change integer values to BlockPos values, but it worked overall!

Hi Everybody,

Does anyone know how to make a new dimension in 1.8? I have looked online for tutorials, but the only ones are for 1.7. Any help is appreciated.

The 72000 seems irrelevant in the way I do it, but I don't really know what it does.

@SubscribeEvent
public void decreaseBowUseDuration(PlayerUseItemEvent.Start event) {
if (event.item.getItem() == null) {
	return;
}

if (!(event.item.getItem() instanceof ItemBow)) {
	return;
}

event.duration -= 10
}

The 10 can be any number from 0 to 18, I think. The higher the number is, the more the duration will be decreased.

The reason link you gave talks about a mapping file. What is it, and how would it be used to generate a javadoc?

March 19, 2015

Can I generate a ZIP file the way it was available earlier?

March 18, 2015

Hi Everybody,

I noticed that on files.minecraftforge.net, there are only javadoc downloads until February 17, 2015. Where can I find the javadoc for the latest version of 1.8?

March 15, 2015

I just tried it out, and it worked.

I think I know what's happening:

The FMLCommonHandler bus registers the PlayerTickEvent, but I need the EVENT_BUS one for the LivingFallEvent. Should I register the class with both of the buses?

March 15, 2015

My code:

//package org.devoxx4kids.forge.mods;
//
//import net.minecraft.entity.player.EntityPlayer;
//import net.minecraftforge.event.entity.living.LivingEvent.LivingUpdateEvent;
//import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
//
//public class Parachute {
//	@SubscribeEvent
//	public void deployParachute(LivingUpdateEvent event) {
//		if (!(event.entity instanceof EntityPlayer)) {
//			return;
//		}
//		if (!((EntityPlayer) event.entity).isAirBorne
//				|| !((EntityPlayer) event.entity).isSneaking()) {
//			return;
//		}
//		event.entity.motionY = -0.05;
//		event.entity.fallDistance = -10;
//	}
//}
package org.devoxx4kids.forge.aods;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.DamageSource;
import net.minecraftforge.event.entity.living.LivingFallEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.TickEvent.PlayerTickEvent;

public class Parachute {
@SubscribeEvent
public void deployParachute(PlayerTickEvent event) {
	EntityPlayer player = event.player;
	if (!player.isAirBorne || !player.isSneaking()) {
		return;
	}
	player.motionY = -0.05;
	player.fallDistance = 0;
}

@SubscribeEvent
public void negateFallDamage(LivingFallEvent event) {
	if (!(event.entity instanceof EntityPlayer)) {
		return;
	}

	EntityPlayer player = (EntityPlayer) event.entity;

	 if (!player.isSneaking()) {
	 return;
	 }

	event.setCanceled(true);
}
}

I tried a bunch of things - canceling the LivingFallEvent, setting its distance to 0, healing the entity, and even LivingHurtEvent with DamageSource as fall, but none of them worked.

The different bus worked, but I still lost health.

Registering code:

FMLCommonHandler.instance().bus().register(new Parachute());

How do I fix the health problem?

March 14, 2015

MinecraftForge.EVENT_BUS.register(new Parachute());

Should it be on a different bus?

March 14, 2015

My code is as follows:

        @SubscribeEvent
public void deployParachute(PlayerTickEvent event) {
	EntityPlayer player = event.player;
	if (!player.isAirBorne || !player.isSneaking()) {
		return;
	}
	player.motionY = -0.05;
	player.fallDistance = 0;
}

With this code, the parachute doesn't even deploy when I press shift in the air. What am I doing wrong?
