How can i make a player invisible to mobs on wearing an specific armor set, by the way the player is not been attacked by them.

 

I've tried this, but the mobs still attack the player:

player.addPotionEffect((new PotionEffect(Potion.invisibility.id, 2, 0)));

 

Thanks for helping.

I'm not sure if this would be the most efficient way, but:

 

1. Setup an entity tick event

2. Check if entity is a mob

3. Check if mob has a target (the player)

4. Remove if it does

There is LivingSetAttackTargetEvent.

 

Ok, but, could you give me some steps to do it? code examples?

Hi

 

This has some useful code

http://www.minecraftforum.net/topic/1419836-131-forge-4x-events-howto/

 

 

Not sure how you would cancel the event, it doesn't seem to be cancelable like normal events, unless I'm missing something.

 

You could perhaps use

 

@ForgeSubscribe
public void entityTarget(LivingSetAttackTargetEvent event)
{
  
  if (event.target != null
     && event.target instanceof EntityPlayer) {
    event.entityLiving.setAttackTarget(null);
  }
}

 

Not sure if that will work since the call to setAttackTarget is reentrant, i.e. will trigger another LivingSetAttackTargetEvent.  Also, setting target to null like this might perhaps cause a crash.

 

And, probably, the mobs will just stand around doing nothing instead of ignoring the player.

 

But it's worth a try :-)

What TGG said, though if you check properly the second post to the set living attack target event should process just fine. Btw, checking instanceof automatically null checks for you:

if (event.target instanceof EntityPlayer) {
((EntityLiving) event.entity).setAttackTarget(null);
}

That will make the mobs mostly just stand around doing nothing, even if you attack them. If you want them to fight back, you should add the following check to the check for instanceof EntityPlayer:

&& event.entityLiving.func_94060_bK() != event.target)

Note also that this only works on mobs that are using the AI system - spiders, for example, will still attack you.

Ok, thanks, it works.

 

Now i have another problem:

 

If the player is firstly invisible, then the mobs don't attack him, but if the mobs are attacking him and the player becomes invisible, the mobs still attack him.

 

This is my code:

/**
 * Only works with AI mobs: Zombies, Skeletons and Creepers.
 * @param event
 */
@SubscribeEvent
public void onEntitySetTarget(LivingSetAttackTargetEvent event)
{
	if (Loader.isModLoaded("SKC-Camouflage"))
	{
		if (event.target != null && event.target instanceof EntityPlayer && event.entityLiving.func_94060_bK() != event.target)
    	{
			if (event.target.isInvisible())
			{
				((EntityLiving) event.entity).setAttackTarget(null);
			}
    	}
	}
    }

			}
    	}
	}
    }

That's because the mob already has a target, so it won't set a new. So you'll have to deal with it, or find a solution for it.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

You could subscribe to LivingAttackEvent as well, checking if the player is invisible and getting the source of the source of damage (yes, you read that right), checking if that is an EntityLiving and then setting their current target to null. Obviously that won't work for everything - creepers, for instance - but it should cover most. Otherwise, you could get all of the living entities nearby the player when they turn invisible and set their targets to null at that time, if their current target is the player turning invisible. Probably simpler to just deal with some mobs still attacking.

Ok, but where's the ".setCurrentTarget()" (or similar) method is located?

You can't be serious... haven't you been paying attention to the thread at all? EntityLiving#setAttackTarget has been featured in probably every single bit of code that has been used in the examples.

 

:'( Sorry for that stupid question, but i've just got up.

 

Ok, did it and the mobs (only tested zombies) don't attack me. But if i touch them then minecraft crashes.

You don't know how to prevent class cast exceptions? It crashed because whatever code you ran is indiscriminately casting every single entity it comes across as an EntityLiving, when the entity may very well not be one, such as the EntityPlayerMP in your crash log.

 

Solution: instanceof

 

EntityLiving and EntityPlayer are both subclasses of EntityLivingBase, but you cannot cast one to the other unless it is an X instanceof Y (you can cast both to EntityLivingBase, if that's what you need, though.) SO, put an 'if' in there to catch that and use logic.

That has nothing to do with the topic, he is trying to use a method in EntityLiving, not EntityLivingBase, so he needs to check if the entity in question is an instanceof EntityLiving before casting. Stop confusing people with random comments.

I don't find your attitude helpful. Perhaps you could keep your snide comments out of the fora.

How is clarifying a statement that confuses the issue at hand being snide or unhelpful? I've seen you give people some excellent advice on challenging questions in other threads, but there have been several cases where you've been either plain wrong or providing extraneous information that diverts from the main point; in the latter cases, I feel it is indeed helpful to point it out and provide either clarification or correction as needed. When I say "stop confusing people with random statements", I'm referring to the latter; for the former, it is helpful to fact-check before posting replies to make sure the information you provide is accurate. If you consider that snide, well, that's your call.

EntityLiving and EntityPlayer are both subclasses of EntityLivingBase, but you cannot cast one to the other unless it is an X instanceof Y (you can cast both to EntityLivingBase, if that's what you need, though.) SO, put an 'if' in there to catch that and use logic.

That has nothing to do with the topic, he is trying to use a method in EntityLiving, not EntityLivingBase, so he needs to check if the entity in question is an instanceof EntityLiving before casting. Stop confusing people with random comments.

Your remarks were and continue to be out of band for these fora. Your tutorials are nice, but all you do is self-advertise your ability to learn from tutorials. So, when all you have to add is "hey, look at my totorial," you really don't have any place suggesting I change my posting habits to suit you.

Now, please grow the hell up and stop this quibbling. It gains nothing and bores me.

      Without Network protocol fix mod, I get kicked with a Network Protocol error when on LAN. Also, both of these issues are caused by a Null Pointer Exception/Screen cannot be null in a "Client Bound Player Combat Kill Packet".

      [1.21.5] The texture of the item is not loading.

      By Pale Mannie · Posted

      You need a new "items" folder at  resources/assets/yourmodid/ there you add for every item model a .json file with the exact item/block name and fill it like this if it's an item: { "model": { "type": "minecraft:model", "model": "yourmodid:item/youritem" } } and so if its a block: { "model": { "type": "minecraft:model", "model": "yourmodid:block/youritem" } } There is also a generator for it you can do namy crazy things with it which replaces the previous hard coded Item Properties implementaion method (Bow pulling animation for example). https://misode.github.io/assets/item/

      Unable to join 1.20.1 server

      By BlueFFlame1 · Posted

      Hello! I'm playing a modpack (custom made) with some friends, and we have the server running on BisectHosting. We encountered a bug with an entity from The Box Of Horrors mod, that would crash the game whenever someone nearby it would log in. We tried to fix it by: 1) Editing the player.dat files to change the location of the affected players (something I had done successfully previously) 2) Updating the version of the mod we had (0.0.8.2) to the latest alpha version (0.0.8.3 However, after doing both of those, none of us are able to join the server, and we get the following errors: Server side: https://pastebin.com/J5sc3VQN Client side: Internal Server Error (that's basically all I've gotten) Please help! I've tried restoring the player data to how it was before I made the changes (Bisect allows you to restore deleted files) and deleting all of my player data files and I still get the same error. Deleting Box Of Horrors causes the error: Failed to load datapacks, cannot continue with server load.

      [1.21.1, Forge 47.4.0] Registering Banner Patterns

      By General_Gunner · Posted

      Hey there! I'm trying to create a simple mod for Forge 1.21.1 that adds a few custom banner patterns that don't require any banner pattern items. To be completely honest, this is my first time modding for Minecraft, so after setting up the project in Intellij, I copied the parts of the source code from this mod on CurseForge that dealt with adding and registering banner patterns, including the lang and banner_pattern .json files. From what I understand, to add a banner pattern that doesn't require a banner pattern item, I only needed to create the registries for each pattern like in here and then register it in the main java class like here on Line 54. Additionally, in the lang/en_us.json file, add in the names for each respective banner color, and in the data/minecraft/tags/banner_pattern/no_items_required.json file, add each banner pattern that does not require a banner pattern item to make a banner. The project is able to compile when loading in Forge which makes me assume that the file structure I have is correct, but on loading a Minecraft world, this error appears in console and the loom is subsequently blank. [Worker-Main-1/ERROR] [minecraft/TagLoader]: Couldn't load tag minecraft:no_item_required as it is missing following references: *lists every added entry in no_item_required.json* The message clearly states something went wrong regarding when trying to load in the registries from the mod, but I have no clue what could be wrong with the code I have. Attached below are screenshots of what I currently have. Java Main Class Banner Registry Class File Structure Error in Console upon loading a Minecraft world What the loom shows without minecraft:no_item_required    The original mod I copied still functions completely, so if anyone can figure out why the registries for the mod I'm making isn't working, that would be greatly appreciated!
