So, I want to make slimeballs throwable. I have a class and everything for throwables that works, only problem is I only know how to turn my custom items into throwables. Can someone tell me how to turn a vanilla item into a throwable without breaking other mods?

Subscribe to 

PlayerInteractEvent.RightClickItem

and do the following:

  • Check if the item is a slimeball
  • Decrement the stack size
  • If the stack size is 0, set the player's held item to 
    null

    and call 

    ForgeEventFactory#onPlayerDestroyItem

    to fire 

    PlayerDestroyItemEvent

    .

  • Spawn your entity
  • Cancel the event to prevent 
    Item#onItemRightClick

    and other handlers from being called

 

Note that even if you cancel the event, processing will still continue to the other hand until this PR is merged and you set the result to 

EnumActionResult.SUCCESS

.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Still not getting it to work even with everything you said, heres the code:

package com.averysumner.randomstuff;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntitySnowball;
import net.minecraft.init.Items;
import net.minecraft.init.SoundEvents;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.stats.StatList;
import net.minecraft.util.ActionResult;
import net.minecraft.util.EnumActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.util.SoundCategory;
import net.minecraft.world.World;
import net.minecraftforge.event.ForgeEventFactory;
import net.minecraftforge.event.entity.player.PlayerInteractEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.registry.GameRegistry;

public class ThrowableSlimeball {

@SubscribeEvent
public void playerRightClickSlime(PlayerInteractEvent.RightClickItem e){
	if (e.getEntityPlayer().getHeldItemMainhand().getItem() == Items.SLIME_BALL) {
        ItemStack playerHeld = e.getEntityPlayer().getHeldItemMainhand();
        
		System.out.println("Slime right clicked!");
		if (!e.getEntityPlayer().capabilities.isCreativeMode)
        {
            --e.getEntityPlayer().getHeldItemMainhand().stackSize;
        }
        
		if (e.getEntityPlayer().getHeldItemMainhand().stackSize == 0) {
			playerHeld = null;
			ForgeEventFactory.onPlayerDestroyItem(e.getEntityPlayer(), e.getEntityPlayer().getHeldItemMainhand(), e.getEntityPlayer().getActiveHand());
		}

		e.getWorld().playSound((EntityPlayer)null, e.getEntityPlayer().posX, e.getEntityPlayer().posY, e.getEntityPlayer().posZ, SoundEvents.ENTITY_SLIME_SQUISH, SoundCategory.NEUTRAL, 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!e.getWorld().isRemote)
        {
            EntitySnowball entitysnowball = new EntitySnowball(e.getWorld(), e.getEntityPlayer());
            entitysnowball.setHeadingFromThrower(e.getEntityPlayer(), e.getEntityPlayer().rotationPitch, e.getEntityPlayer().rotationYaw, 0.0F, 1.5F, 1.0F);
            e.getWorld().spawnEntityInWorld(entitysnowball);
        }
        e.setCanceled(true);
	}

}
}

Btw, I am just spawning snowballs atm to test it.

I got everything working, besides rendering my slimeball entity. When I use "RenderingRegistry.registerEntityRenderingHandler" I get @Deprecated, even if I use the factory version.

Take a look at how my rendering is handled at

https://bitbucket.org/The_Fireplace/fires-random-things/src/master/src/main/java/the_fireplace/frt/client/ClientProxy.java

It isn't a big change from how you're doing it now, it just needs an extra class, the render factory. Unless something has changed again in 1.10, this way of doing it isn't deprecated.

I need to see the code where you register it to know what the problem is. Also, this code over complicates things a bit, I didn't expect you to make an almost exact copy of the more complex of my two projectile rendering classes. My code there is designed for multiple projectiles to use the same class.

 

Here is a simpler example, which better suits your purpose, that you can use if you want something to copy, paste, and edit, though I strongly suggest you look in to it and make sure you understand what all of it does.

My renderprojectile:

https://bitbucket.org/The_Fireplace/fires-random-things/src/master/src/main/java/the_fireplace/frt/client/renderers/RenderPigderPearl.java

My Render factory:

https://bitbucket.org/The_Fireplace/fires-random-things/src/master/src/main/java/the_fireplace/frt/client/renderers/PigderPearlRenderFactory.java

And how I registered this is on line 31 of the ClientProxy class I linked you to before.

 

Edit: as for the entity pushing you, I am too tired to look in to it right now. I suggest you start a new thread about it, we have already derailed this one enough.

If I helped please press the Thank You button.

Hey fireplace, I made it a lot more simple by modifying your simpler render class, but I still get no textures. I posted my registry in an older post.
