hello

 

so ...  i need to know how i can check if a boolean from annother class is true and then issue some code ... using a simple if statement, but what do i need to type my boolean is called CheckInventoryTrader1 ... can someone please tell me how to do it

 

 

 

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

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

 

And where is this function?

And where is this function?

 

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;
   }
    
    
    
}

still havent found it out, even if it is something simple please just ask if you need to see anything but i warn you ... its messy

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.

okay but then what do i need to add in the tileentity

okay but then what do i need to add in the tileentity

 

Or the Living Entity.  Whateverthehellentity that lets you open the GUI that has the slots in it.

that will be this entity

so what do i need to add?!?

/**
     * Called when an the contents of an Inventory change, usually
     */
    public void onInventoryChanged() { ... }

but how do i use that void for what i wanna do?!? if you need more files just ask

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.

but then how do i put i item inside the output slot?!?

but then how do i put i item inside the output slot?!?

 

slot.putStack(ItemStack item)
