So, I'm trying to make an item that when it is right clicked with the effect changes (adds the shiny nether start effect over it). I looked at some things online, and I'm ending up using this:

 

@SideOnly(Side.CLIENT)

    public boolean hasEffect(ItemStack itemStack)

    {

        return effectChange;

    }

 

 

effectChange is:

 

@Override

    public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer entityPlayer)

    {

        effectChange = !effectChange;

        return itemStack;

    }

 

 

However, when I look at my overridden hasEffect in IntellijIdea, it crosses it out and shows that its deprecated. What should I use instead then?

If you looked in Item, you'd see it: "public boolean hasEffect(ItemStack par1ItemStack, int pass)"

Also, don't store the hasEffect in the item class, else it will be shared across all item instances.

So, where would I want it?

 

EDIT: Hmm, I see another declaration of hasEffect below, with int pass as one of the arguments. I'll look into that. But still. Where would I want it if not in the item class? Where else would I say that?

You can store it in the ItemStacks stackTagCompound.

Roboman, the method is fine in your Item class.

 

larsgerrits, 'hasEffect' is not a class field, it's a class method, otherwise you would be right, at least in the case of wanting to have a unique value for each stack, rather than per item. It sounds like the OP just wants every Item of this type to have the glow.

No, thats not quite what I want. When the item is right click with (used, but not used up), I want that item to have the glow activated over it. Only that one, not all of that type. I understand why it shouldn't be in the item declaration class, but where should I have it is my question?

 

Also, the code I posted in the OP makes the item flicker quickly when right clicked with. Any ideas why this might happen? I think it has something to do with it being in the wrong spot.

Ah... sorry larsgerrits, I didn't see the addition of code to the OP

 

@OP You need to store it in the ItemStack NBT, like largerrits mentioned, and make sure you only do it once per right click, and do it on the server - NBT should sync automatically for ItemStacks.

Sorry, I'm new to forge coding, and new to Java (But don't fear! I know how to program and have looked at many examples, I'm not clueless). I need to store it in the ItemStack NBT, thats something I need to define, isn't it. Also, doing it on the server is a simple as @SideOnly(Side.SERVER), right? If you could lead me through at least one of these things, I think I can figure out how to do it.

 

I'm doing this just to see what I CAN do and what I know I can do, this exercise is doing what its meant to do

No, don't use @SideOnly; in the method parameters for onItemRightClick, there is a 'World' object, named 'world' -> use that to check side:

if (world.isRemote) {
// you are on the client right now
}
// if (!world.isRemote) means you are on the server

 

For NBT tags, they are stored in the ItemStack already, not something you add to your class. Use them like this:

// 'stack' is the ItemStack from the method parameters, and this goes inside the method

// always check if the stack has a tag compound before you try to use it:
if (!stack.hasTagCompound()) {
stack.setTagCompound(new NBTTagCompound());
}
if (!world.isRemote) { // on the server
// there are lots of different 'set' methods for NBTTagCompounds
// each tag is stored with a String key, such as 'isGlowing':
boolean isGlowing = stack.getTagCompound().getBoolean("isGlowing");
// now store the opposite:
stack.getTagCompound().setBoolean("isGlowing", !isGlowing);
}
}

 

Then in your hasEffect(ItemStack, int) method, you can return 'stack.hasTagCompound() && stack.getTagCompound().getBoolean("isGlowing")'

Thank you so much! I'm trying this now to see if I can get this to work.
