[1.7.10][SOLVED]detecting Item right click crash

[thewaterwell]

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.

[Jacky2611]

Please check if the item is null before you execute that code.

I believe that it returns null if your hand is empty.

[thewaterwell]

my hand was not empty, I was holding the Item. I tried holding bottles of enchanting from vanilla and empty hand, all crashed.

[Jacky2611]

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;
    }

}

hi,

I tried it, but in the code I try to create and set NBT to the stack but it crashes with the following:

Please post your items code.

[thewaterwell]

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;
}
}

[coolboy4531]

Does it print out "ON ITEM USE" when you use the item?

[Jacky2611]

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.

[thewaterwell]

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.

[Jacky2611]

What is in your ItemMyMod class?

Please try to expand "Item"

[3izzo]

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

[thewaterwell]

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.

[Jacky2611]

What exactly do you want to happen if you right click something?

[thewaterwell]

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.

[Jacky2611]

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.

[thewaterwell]

ok, am trying to find a place where it runs and does not just sit there

 

EDIT: found it, now to get the if working...

[Jacky2611]

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.

[thewaterwell]

I used the onItemRightClick and it worked! thank you for helping eveyone!
