If it's not a static variable, then you need a reference to an instance of that class.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

well here is the boolean:

 

    //checking if the placed item is "Hydrocroconyzx ingot" only retuns false if there is no item in the slot since no othere item/block  is allowed in the slot
   public boolean CheckInventoryTrader1(ItemStack par1ItemStack) {
       
       Item item = par1ItemStack.getItem();
       
       if(par1ItemStack != null && item == EsteticsPLUS.HydrocroconyxIngot){
           return true;
       }
       
       else return false;
   }

 

im not intirely sure on how to do so if you can post the code that would be nice

its in my slot class here:

 

package EsteticsPLUS;


import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.inventory.Slot;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;



public class SlotTrader1 extends Slot{

    public SlotTrader1(EntityPlayer player, IInventory par1iInventory, int par2, int par3, int par4) {
        super(par1iInventory, par2, par3, par4);
        
    }
    
    @Override
    public boolean isItemValid(ItemStack par1ItemStack) {
            if (par1ItemStack != null)
           {
                    Item item = par1ItemStack.getItem();
                    return item != null && item == EsteticsPLUS.HydrocroconyxIngot;
            }
            return false;
    }
   
    
    //checking if the placed item is "Hydrocroconyzx ingot" only retuns false if there is no item in the slot since no othere item/block  is allowed in the slot
   public boolean CheckInventoryTrader1(ItemStack par1ItemStack) {
       
       Item item = par1ItemStack.getItem();
       
       if(par1ItemStack != null && item == EsteticsPLUS.HydrocroconyxIngot){
           return true;
       }
       
       else return false;
   }
    
    
    
}

When you put a function in a class it is assumed that you need it in that class.  You're not using it in that class (it is, in fact, identical to the isItemValid function) but you want to call that function from another class....why?

so im making this slot system where you have 2 slots that are inputs and then have a output that is triggered using that boolean(have one in the other slot too) and then from that i can display a metadata block and have a upp and a down button that can modify the output be adding one to the metadata or remove one(hint: i talked a little bit with Vswe about it)

That is not how you should be doing things.

 

The two input slots handle whether or not the item is valid, the TileEntity should handle if both slots are filled and put the output item in the output slot.

    @Override

    @Override

            NBTTagList tagList = tagCompound.getTagList("Inventory");
            for (int i = 0; i < tagList.tagCount(); i++) {
                    NBTTagCompound tag = (NBTTagCompound) tagList.tagAt(i);
                    byte slot = tag.getByte("Slot");
                    if (slot >= 0 && slot < inv.length) {
                            inv[slot] = ItemStack.loadItemStackFromNBT(tag);
                    }
            }
    }

    @Override
    public void writeToNBT(NBTTagCompound tagCompound) {
            super.writeToNBT(tagCompound);
                            
            NBTTagList itemList = new NBTTagList();

                    ItemStack stack = inv[i];
                    if (stack != null) {
                            NBTTagCompound tag = new NBTTagCompound();
                            tag.setByte("Slot", (byte) i);
                            stack.writeToNBT(tag);
                            itemList.appendTag(tag);
                    }
            }
            
            
            tagCompound.setTag("Inventory", itemList);
    }

            @Override
            public String getInvName() {
                    return "EsteticsPLUS.tileentitytrader";
            }

            @Override
            public boolean isInvNameLocalized() {
                return true;
            }

            @Override
            public boolean isStackValidForSlot(int i, ItemStack itemstack) {
                return false;
            }
       
}

That void function is the function that checks the slots to see if both have items, and if so, do whatever needs to be done.
