[1.5.1]GUI: detecting certain blocks(SOLVED)

[rasmustof]

hello

 

so im making something that requires that i need to detect if the block placed in the slot is the sand block(Block.sand)

 

so this is what i did for a item:

    //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;
   }
    
    

 

and then i dont know how to do the same kind of thing, but with the Sand block or any kind of block for that matter

first I would suggest a couple of changes to your code.

    //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) {
       
       if(par1ItemStack != null){
           Item item = par1ItemStack.getItem();
           
           if(item.equals(EsteticsPLUS.HydrocroconyxIngot))
               return true;
           else if(item.equals(Block.sand))
               return true;
           else if(item.equals(ITEM_OR_BLOCK_HERE))
               return true;
       }
       
       return false;
   }
    

when you compare things that have Object as a parent, you use .eqauls() to compare them. if they're primitives, then you can use ==. you should also check if the ItemStack is null before getting the item otherwise it can cause crashes. "else return false" is the same as "return false"
