You are comparing a Itemstack:heldItem with a Item:Item.ender_pearl. If you want to compare those 2, you need to get the item out of the ItemStack and compare that with the item. Then you can update the PT variable.

A block is a static Object, so if you set a variable to one in the world, they all get the same variable. So if you want to make a variable that's unique to each block, you need to make it a TileEntity, or you can make all seperate blocks.

Show all classes related to your backpack item.

Can you post a screenshot? I don't exactly know what you mean.

Add these 2 methods to your block: public boolean renderAsNormalBlock() { return false; } public boolean isOpaqueCube() { return false; } That did it for me.

What does your code currently do?

The only thing i can think of, is that you look through all of your classes related to the market, and look for something that looks for chestContents[6] and change it to chestContents[5].

Can you see the actual texture in your eclipse environment?

Can you post the full crash log? Then i can figure out where the problem occurs

Try using back slashes in the ResourceLocation definition

Then this happens RIGHT_CLICK_AIR cannot be resolved or is not a field

If you have a array which has 6 thingys, it ranges from 0-5. So if you do something like this: YOUR_ARRAY[6], it will try to find slot 7 but that doesn't exist. So that's why you get a ArrayIndexOutOfBoundsException.

Do I replace the return new BasicGui(player.inventory, (BasicTileEntity) tileEntity) with the thing I suggested? because I can only return one or the other Also, if I wanted to say create a backpack, how on right click with the backpack item, it would open a chest inventory and store the contents in the item, would I only need a IGuiHandler and a GuiContainer, or those 2 and a container? That's the line you need to replace. I haven't done anything with backpack type stuff, but i know what you need: Something with IInventory A GuiContainer class A Container class A GuiHandler (you already got one)

Yeah, that should work.

In your GuiHandler: @Override public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) { TileEntity tileEntity = world.getTileEntity(x, y, z); if(tileEntity instanceof BasicTileEntity) { return new BasicGui(player.inventory, (BasicTileEntity) tileEntity); } return null; } You're returning a gui on the server side, but you need to return a container class.

No,you don't need to learn any of these to make a gui. If you want to change values client and server side, you want to use packets. If you want your mod to be checking for a specific value on a player which is set by the gui, you want to use a tick handler. NBT is for saving information trough a world reload, and tile entitys are for block which need to store/do more stuff then a regular block can save/do.

Actually, eclipse has a icon like that. When you have a green arrow pointing up in that sidebar, you can see what that method does, in my case

Can you post the full crash log? Line 261 seems correct to me.

Thanks to all of you! I used the way that diesieben07 linked and it worked!

At the handlePacket method, how can you make that method? (I'm not good with packets yet, this is the first time i used them)

Ok, i tried using packets, but i can't find find a way to update the tileentity value... Can anyone give a good tutorial, or some code (possibly some pseudocode)?

So i have to use packets? Damnit, guess it's time to learn how to deal with packets...

Hello, i got another problem for you now. I have a value that's getting updated on the client side, but not on the server side. The way i update the code is via a GUI, when a click a button it's incrementing or decrementing a value and setting it to a TileEntity. In my container class i have some debug code: System.out.println((tileentity.worldObj.isRemote ? "Client" : "Server") + " : " + tileentity.getPage()); That prints this in the console: 2014-02-24 17:00:47 [iNFO] [sTDOUT] Server : 0 2014-02-24 17:00:47 [iNFO] [sTDOUT] Client : 0 And if i increment the value using a button, this is getting printed in the console: 2014-02-24 17:07:41 [iNFO] [sTDOUT] Server : 0 2014-02-24 17:07:42 [iNFO] [sTDOUT] Client :1 As you see the value is getting updated client-side, but not on the server side. I added this code to my TileEntity class: public Packet getDescriptionPacket() { NBTTagCompound tag = new NBTTagCompound(); this.writeToNBT(tag); return new Packet132TileEntityData(this.xCoord, this.yCoord, this.zCoord, 1, tag); } public void onDataPacket(INetworkManager networkManager, Packet132TileEntityData packet) { this.readFromNBT(packet.data); } But that doesn't seem to work. I have registered my TileEntity class. Does anyone know how to correctly syncronize that value?

You could also use the RenderGameOverlayEvent and then check if it is the GuiMainMenu class and then cancel the rendering and then render your own menu
