Item right click:

@Override
public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand)
    {     
        	if (!worldIn.isRemote)
        	{
        		EntityTractor entity = new EntityTractor(worldIn);
        		entity.setPosition(playerIn.posX, playerIn.posY, playerIn.posZ);
        		worldIn.spawnEntityInWorld(entity);

        		--itemStackIn.stackSize;
            return new ActionResult(EnumActionResult.SUCCESS, itemStackIn);
        }
        else
        {
            return new ActionResult(EnumActionResult.PASS, itemStackIn);
        }
    }

Hi

 

Try Rebuild All on your project.

 

-TGG

It didn't help.

It didn't help.

 

use my code, it work on me 

 

public class FireBallItem extends Item
{
    public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand)
    {
        if (!playerIn.capabilities.isCreativeMode)
        {
            --itemStackIn.stackSize;
        }
        worldIn.playSound((EntityPlayer)null, playerIn.posX, playerIn.posY, playerIn.posZ, SoundEvents.ENTITY_SNOWBALL_THROW, SoundCategory.NEUTRAL, 0.4F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));
        if (!worldIn.isRemote)
        {
            FireBall entitythrowable = new FireBall(worldIn, playerIn);
            entitythrowable.setHeadingFromThrower(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 1.5F, 1.0F);
            worldIn.spawnEntityInWorld(entitythrowable);
        }
        playerIn.addStat(StatList.getObjectUseStats(this));
        return new ActionResult(EnumActionResult.SUCCESS, itemStackIn);
    }
}

 

 

EDIT: ofc you have to configure it for yourself , but it should work out

 

@Override
public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand)
    {   
	if (!playerIn.capabilities.isCreativeMode)
        {
            --itemStackIn.stackSize;
        }

        if (!worldIn.isRemote)
        {
        	EntityTractor Tractor = new EntityTractor(worldIn);
        	Tractor.setPosition(playerIn.posX, playerIn.posY, playerIn.posZ);
        	worldIn.spawnEntityInWorld(Tractor);       
        }
        	
        playerIn.addStat(StatList.getObjectUseStats(this));
        return new ActionResult(EnumActionResult.SUCCESS, itemStackIn);
    }

 

Still the same error.

" cz.grossik.farmcraft2.tractor.EntityTractor"

 

post this class here please.

 

and your "main class" / "proxy"

I already solved it, in Entity I had    @SideOnly(Side.CLIENT)
