hello,

 

I want to operate a piece of code when a item is right clicked.

I get a crash from the following code:

@SubscribeEvent
public void ExpCatalyst (PlayerInteractEvent event)
{
//crash here
if(event.entityPlayer.getItemInUse().getItem().getUnlocalizedName().contains(ModItems.expCatalyst.getUnlocalizedName()) && ModItems.expCatalyst.getUnlocalizedName().contains(event.entityPlayer.getItemInUse().getItem().getUnlocalizedName()) )

 

the crash report is here

From what I tried, I saw the crash was caused because "getItemInUse()" returned null, but I right clicked the Item.

 

If anyone could help, I would highly appreciate.

Wait, this is a custom Item, right?

Why don't you check if its right clicked inside the Item? like this:



public class ItemDust extends Item {

public ItemDust(int maxStackSize, String name) {
        setUnlocalizedName(name);
        setTextureName(DimensionShift.MODID + ":" + name);

}

@Override
    public boolean onItemUse(ItemStack itemstack, EntityPlayer player, World world, int x, int y, int z, int side, float px, float py, float pz){
	System.out.println("ON ITEM USE");

        return true;
    }

}

Here could be your advertisement!

ok here it is... this is what is in the item's code regarding this not working. I registered it and maybe added a crafting recipe, that is all.

 

public class ItemExpCatalyst extends ItemMyMod
{
public ItemExpCatalyst()
{
super();
this.setUnlocalizedName("expCatalyst");
this.setMaxStackSize(1);


}
@Override
    public boolean onItemUse(ItemStack itemstack, EntityPlayer player, World world, int x, int y, int z, int side, float px, float py, float pz)
{
	System.out.println("ON ITEM USE");
	if (player.experienceLevel>0 && player.isSneaking())
	{
		NBTHelper.setInteger(itemstack,"exp stored", (NBTHelper.getInt(itemstack,"exp stored")+1));
		System.out.println("EXP Stored: "+NBTHelper.getInt(itemstack,"exp stored"));
		if(!player.capabilities.isCreativeMode)
		{
			player.addExperienceLevel(-1);
		}
	}
	if (!player.isSneaking())
	{
		System.out.println("not crouching");
		System.out.println(NBTHelper.getInt(itemstack,"exp stored"));
		if (NBTHelper.getInt(itemstack, "exp stored")>0)
		{
			System.out.println("outputing levels...");
			player.addExperienceLevel(1);
			if(!player.capabilities.isCreativeMode)
			{
			NBTHelper.setInteger(itemstack,"exp stored", NBTHelper.getInt(itemstack,"exp stored")-1);
			}
		}
	}

        return true;
}
}

Did you create a NBTHelper class in an utility package?

 

@coolboy4531 looks like the item class is not the problem:

java.lang.NullPointerException: Unexpected error
   at com.thewaterwell.letsmodreboot.utility.NBTHelper.initNBTTagCompound(NBTHelper.java:29)
   at com.thewaterwell.letsmodreboot.utility.NBTHelper.getInt(NBTHelper.java:125)
   at com.thewaterwell.letsmodreboot.handler.EventHandler.ExpCatalyst(EventHandler.java:42)

 

 

 

EDIT: Please remove everything from your ExpCatalyst event handler.

I removed it from the event handler and yes, I have a NBTHelper class in the utility package.

since then, it stopped crashing but it does not print the "ON USE ITEM".

I think it is because I am regisrting the Item as the top function only but I am uncertain.

why don't you use onItemRhightClick Method (used in snow balls/eggs)?

I did not really understand how to. I would be greatful if you would show me how

 

What is in your ItemMyMod class?

Please try to expand "Item"

 

here is the code for ItemMyMod

 

public class ItemMyMod extends Item
{
    public ItemMyMod()
    {
        super();
        this.setCreativeTab(CreativeTabLMRB.LMRB_TAB);
    }

    @Override
    public String getUnlocalizedName()
    {
        return String.format("item.%s%s", Reference.MOD_ID.toLowerCase() + ":", getUnwrappedUnlocalizedName(super.getUnlocalizedName()));
    }

    @Override
    public String getUnlocalizedName(ItemStack itemStack)
    {
        return String.format("item.%s%s", Reference.MOD_ID.toLowerCase() + ":", getUnwrappedUnlocalizedName(super.getUnlocalizedName()));
    }

    @Override
    @SideOnly(Side.CLIENT)
    public void registerIcons(IIconRegister iconRegister)
    {
        itemIcon = iconRegister.registerIcon(this.getUnlocalizedName().substring(this.getUnlocalizedName().indexOf(".") + 1));
    }

    protected String getUnwrappedUnlocalizedName(String unlocalizedName)
    {
        return unlocalizedName.substring(unlocalizedName.indexOf(".") + 1);
    }
}

this is from pahimar's tutorial.

what I am aiming for is for the item ItemExpCatalyst to serve as an exp "battery".

sneak right click to charge and right click to absorb.

 

p.s. I am going to try using onItemRightClick, to check.

Yeah, that should work. If i am right onItemUse is only triggered if you right click a block in the world.(and gives you the coords of that block)

If you want to trigger it always you should use the rightClick method.

 

Sry, i should have mentioned that earlier.

Try to use

 

    /**
     * Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
     */
    public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
        //YOUR CODE HERE
        return par1ItemStack;
    }

 

instead of the onItemUse thing.

      REVIEW OF THE BEST BITCOIN RECOVERY TEAM - MUYERN TRUST HACKER

      By andreygagloev · Posted

      When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )

      corail tombstone fire crash

      By Ugdhar · Posted

      You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

      corail tombstone fire crash

      By belzabel · Posted

      So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
