Custom Dispenser Behaviour Help

[Jacknoshima]

Okay, I have my custom spawn eggs all set up and they work perfectly

 

Except when I use them with a dispenser they only fire out the egg, not spawn the entity

 

I've made my own dispenser behaviour class here

 

 

package advmobs;

import net.minecraft.block.BlockDispenser;
import net.minecraft.dispenser.BehaviorDefaultDispenseItem;
import net.minecraft.dispenser.IBlockSource;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.item.ItemMonsterPlacer;
import net.minecraft.item.ItemStack;
import net.minecraft.util.EnumFacing;

final class DispenserBehaviourAdvMobEgg extends BehaviorDefaultDispenseItem
{
    /**
     * Dispense the specified stack, play the dispense sound and spawn particles.
     */
    public ItemStack dispenseStack(IBlockSource par1IBlockSource, ItemStack par2ItemStack)
    {
        EnumFacing enumfacing = BlockDispenser.getFacing(par1IBlockSource.getBlockMetadata());
        double d0 = par1IBlockSource.getX() + (double)enumfacing.getFrontOffsetX();
        double d1 = (double)((float)par1IBlockSource.getYInt() + 0.2F);
        double d2 = par1IBlockSource.getZ() + (double)enumfacing.getFrontOffsetZ();
        Entity entity = AdvMobsPlacer.spawnCreature(par1IBlockSource.getWorld(), par2ItemStack.getItemDamage(), d0, d1, d2);

        if (entity instanceof EntityLivingBase && par2ItemStack.hasDisplayName())
        {
            ((EntityLiving)entity).setCustomNameTag(par2ItemStack.getDisplayName());
        }

        par2ItemStack.splitStack(1);
        return par2ItemStack;
    }
}

 

 

It's basically the same as the vanilla one except I've subsituted ItemMonsterPlacer with my own

 

According to another topic I read they said it needed to be registered, but didn't say how they managed it. I've searched, quite a lot, and can't find any answers on how to register a new dispenser behaviour, if you do actually need to, and I can't find anything about it in the code

 

So, can anyone help me and show me how I'm supposed to register this? or explain why it isn't working? if you need code from my mob placer item I can provide.

 

EDIT: I know this is probably gunna be something really easy, I just can't seem to get it

Look at net.minecraft.dispenser DispenserBehaviorMobEgg

 

You'll probably need to duplicate that class for your spawn eggs and add the behavior to the dispenser behavior listing (see DispenserBehaviors).

The DispenserBehaviours bit was what I was missing

I knew it would be simple

 

Thank you

[Jacknoshima]

Okay, scratch that, it's still not working

 

I added in a new class for the registering

 

 

package advmobs;

import net.minecraft.block.BlockDispenser;
import net.minecraft.dispenser.DispenserBehaviors;

public class AdvMobBehaviours {

    public static void registerVanillaDispenserBehaviors()
    {
        BlockDispenser.dispenseBehaviorRegistry.putObject(Advmobs.advmobsplacer, new DispenserBehaviourAdvMobEgg());

    }
}

 

 

and the DispenserBehaviourAdvMobEgg is the same as in my original post

 

I tried adding

 

        BlockDispenser.dispenseBehaviorRegistry.putObject(Advmobs.advmobsplacer, new DispenserBehaviourAdvMobEgg());

 

into the main mod file but to no avail

 

I've also tried changing the method name, extending DispenserBehavior with that name and another name

so

am I missing something else?

[Draco18s]

Are you making sure that this code is getting called?

 

Also, when I mucked about with this, I called it in my mod's PostInit function, and it worked (but I was also adding custom behaviors to a custom dispenser).

[Jacknoshima]

Yeah, I just needed to put it in the PostInit apparently

 

Thank you

... again haha

[Draco18s]

Yeah, I just needed to put it in the PostInit apparently

 

I'm not surprised.

I had mine in postInit for a good reason (cough, probably because I backtracked the vanilla code to figure out when it registered its behaviors).
