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:

package com.gpa.startrekmod.tileentities;

import java.util.List;

import com.gpa.startrekmod.blocks.STModBlocks;
import com.gpa.startrekmod.items.STModItems;

public class TileEntityReplicatorBlock extends TileEntity implements ISidedInventory {
private ItemStack[] slots = new ItemStack[2];
private final String IventoryName = "Replicator";
private int facingDirection;
public int maxPower = 100000;
public float power;
public void updateEntity(){
if(ItemStack.areItemStacksEqual(new ItemStack(STModItems.EnergyCell), slots))
{
	power += 10;
}
else
{

}
if(power > maxPower) power = maxPower;
}
public int getPowerScaled(int scaled)
{
	return (int) (this.power * scaled / this.maxPower);
}
@Override
public void readFromNBT(NBTTagCompound nbt){
	super.readFromNBT(nbt);

	facingDirection = nbt.getInteger("facingDirection");
	NBTTagList list = nbt.getTagList("Slots", 10);
	this.slots = new ItemStack[getSizeInventory()];

	for(int i = 0; i < list.tagCount(); i++){
		NBTTagCompound  item = list.getCompoundTagAt(i);
		byte b = item.getByte("Item");

		if(b >= 0 && b < this.slots.length){
			this.slots[b] = ItemStack.loadItemStackFromNBT(item);
		}
	}

	this.power = nbt.getInteger("REPPower");

	if(nbt.hasKey("CustomName")){
		this.setInventoryName(nbt.getString("CustomName"));
	}
}
@Override
public void writeToNBT(NBTTagCompound nbt){
	super.writeToNBT(nbt);

	nbt.setFloat("REPPower", this.power);
	nbt.setInteger("facingDirection", facingDirection);
	NBTTagList list = new NBTTagList();

	for(int i = 0; i < this.slots.length; i++)
	{
		if(this.slots[i] != null){
			NBTTagCompound item = new NBTTagCompound();
			item.setByte("item", (byte)i);
			this.slots[i].writeToNBT(item);
			list.appendTag(item);
		}
	}
	nbt.setTag("Slots", list);

	if(this.hasCustomInventoryName()){
		nbt.setString("CustomName", this.getInventoryName());
	}
}

public int getSizeInventory() {
	return this.slots.length;
}
public ItemStack getStackInSlot(int i) {
	return this.slots[i];
}
public ItemStack decrStackSize(int i, int j) {

		if(this.slots[i].stackSize <= j)
		{
			itemstack = this.slots[i];
			this.slots[i] = null;
			return itemstack;
		}else{
			itemstack = this.slots[i].splitStack(j);
			if(this.slots[i].stackSize == 0)
			{
				this.slots[i] = null;
			}
			return itemstack;
		}
	}
	return null;
}
public ItemStack getStackInSlotOnClosing(int i) {
	if(this.slots[i] != null)
	{
		ItemStack itemstack = this.slots[i];
		this.slots[i] = null;
		return itemstack;
	}
	return null;
}
public void setInventorySlotContents(int i, ItemStack itemstack) {
	this.slots[i] = itemstack;

	if(itemstack != null && itemstack.stackSize > this.getInventoryStackLimit()){
		itemstack.stackSize = this.getInventoryStackLimit();
	}
}
public String getInventoryName() {
	return null;
}
public void setInventoryName() {

}
public boolean hasCustomInventoryName() {
	return false;
}
public int getInventoryStackLimit() {
	return 64;
}
public void setInventoryName(String string){

}
public boolean isUseableByPlayer(EntityPlayer p_70300_1_) {
	return false;
}
public void openInventory() {
}
public void closeInventory() {
}
public boolean isItemValidForSlot(int p_94041_1_, ItemStack p_94041_2_) {
	return false;
}
public int[] getAccessibleSlotsFromSide(int p_94128_1_) {
	return null;
}
public boolean canInsertItem(int p_102007_1_, ItemStack p_102007_2_,
		int p_102007_3_) {
	return false;
}
public boolean canExtractItem(int p_102008_1_, ItemStack p_102008_2_,
		int p_102008_3_) {
	return false;
}
@Override
public Packet getDescriptionPacket() {
NBTTagCompound tag = new NBTTagCompound();
this.writeToNBT(tag);
return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 1, tag);
}
}

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:

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.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
