Solved Trying to prevent a player from mounting a horse

Im working with the NMS and im trying to override the method private void i(EntityHuman entityhuman) but it dosent work even tho it is in the mc dev repository.

ERROR: The method i(EntityHuman) of type CustomHorse must override or implement a supertype method
The error is in the compiler

Code:

import net.minecraft.server.v1_8_R3.EntityHuman;

Code:

@Override
private void i(EntityHuman entityhuman) {}

link to mc dev net/minecraft/server: https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityHorse.java

 

That McDev is for 1.7.10

The obfuscation changes every update, so your i() may be completely different now

@NortherKnight
Try this

Code:

  
    @EventHandler
    public void asd(PlayerInteractEntityEvent event) {
      
      
        if(event.getRightClicked() instanceof Horse) {
          
            event.setCancelled(true);
          
        }
      
    }

 

@Gonmarte That would work but i need the event to open a inventory and i dont want to disable mounting horses for every horse just the custom ones.

 

@NortherKnight
Well, Can you show us your Entity class? What does it currently look like?

Code:

        return o;

    {

    @Override

}

 

Looked back at the other posts:

Update to 1.7.10 (in the link you gave)

You may need to find the updated class.

Try asking THIS GUY where he got the updated entity classes from.

 

@Zombie_Striker I tryed decompiling the spigot server 1_8_R3 but its still the same method and it still does not work i just can override the i method :/

 

@NortherKnight
The reason you can't override it is because the method is private (link), you're gonna have to find an alternative

 

@megamichiel yea but other then this method i cant find the alternative in the EntityHorse (methods are ingeniously named :/)

 

That's because you're really not supposed to know what the methods are or what they do, why not just make a entity mount event and check if the entity being mounted is your horse?

 

@Xerox262

 

You can give the horse a name then check if the name of the horse being mounted matches your custom horse's name.

 

@Xerox262 yea i did but it still says its name is Horse when all my other mobs work i double checked the code.

 

It's not working? I decompiled the EntityHorse class and saw a method called ae with no paramaters, it appears to return if a horse has a passenger or not (false if it does and true if it doesn't) try overriding the ae method and returning false, it should trick it into thinking that it already has a passenger then disallow you to mount any custom horse

@Xerox262 No dice tryed it dosent do anything (i tryed returning false/true)

 

How're you spawning the horse? Are you sure it's your custom horse that is being spawned?

 

@Xerox262 yea since he cant move and has no collide
His name should be CHorse like others but its not i dont know why

 

Is CHorse showing up above it's head? and how are you getting the name again?

 

@Xerox262 I getting my name by checking it when i interact with an entity with the e.getRightClicked().getName()

 

Why aren't you using entity mount event?

 

@NortherKnight
I looked through the EntityHorse class, and the a(EntityHuman) method might interest you. It's called whenever a player right clicks the entity.

 

@megamichiel yea it works now but it still changes the yaw and pitch of the player to match the horse + I dont know why the custom entity dosent have the name CHorse yet it behaves as a custom entity all my other entityes are working fine :/

 

Yea fixed the naming issue with overriding the setName but i still couldnt get the yaw and pitch to not change because its in a private method

 

@NortherKnight
Set the method as Accessible using setAccessible?
