[1.7.10] [Resolved] How to check Item in Slot - TileEntity Interface

[Alanzote]

Hi,

I am making a TileEntity, I want to check if Item: "PowerGive", it is slot, then it adds power.

How can I do that?

 

Thank you for your attention,

Alanzote.

[larsgerrits]

Show your code?

[Alanzote]

updateEntity is called every tick. Use that method.

I know, but what I need it's how? How can I make it check for the item?

[Alanzote]

Hi, sorry for the delay, I've been searching for a way to do this, I think I found it:

public void updateEntity(){
          if(ItemStack.areItemStacksEqual(new ItemStack(Item.Cobblestone), slots))
          {
              power += 10;
          }
          else
          {

          }
}

I need to check the Item in slot, here is my ItemStack variable that stores the content:

private ItemStack[] slots = new ItemStack[2];

but It says that I am using a wrong type of ItemStack in the 2Nd variable of the Content, here is all my TileEntity Code:

For some reason the spoiler tab is not working.

 

Thanks.

I used slots with the ID of the slot after it:

slots[1]

I got no error, but I am getting a minecraft crash Report, It's about the ticking:

Thanks!

[Alanzote]

I've tried accessing these arrays: 1 and 2.

It is still now working.

[larsgerrits]

I've tried accessing these arrays: 1 and 2.

It is still now working.

private ItemStack[] slots = new ItemStack[2];

2 elements, meaning indices 0 and 1.

[Alanzote]

I used array 0. It is not giving the power.

[Alanzote]

I am making some kind of furnace, that uses power and has an output.

[Alanzote]

LOL! I am so stupid. I've adjusted the value to 100 and the power bar filled up!
