I created code that recognize what object is in input slot and if it's white it add white item to output slot and if it's orange it outputs orange item.
if (button.id == 0){

if((Filamencik.getStackInSlot(00) !=null ) &&Filamencik.getStackInSlot(00).getItem() == bialyfilament.block){ Filamencik.setInventorySlotContents(01, new ItemStack(bialymarfin.block, 1)); }

if((Filamencik.getStackInSlot(00) !=null ) &&Filamencik.getStackInSlot(00).getItem() == bialyfilament.block){ Filamencik.setInventorySlotContents(00, null); }

if((Filamencik.getStackInSlot( 00) !=null ) &&Filamencik.getStackInSlot( 00).getItem() == pomaranczowyfilament.block){ Filamencik.setInventorySlotContents(01, new ItemStack(pomaranczowyMarfin.block, 1)); }

if((Filamencik.getStackInSlot( 00) !=null ) &&Filamencik.getStackInSlot( 00).getItem() == pomaranczowyfilament.block){ Filamencik.setInventorySlotContents(00, null); } } }
 

if i insert item to input slot and press event button input item dissapear, output item shows. If i quit GUI in that moment output item will come out, but when i click output item in GUI it disappears and input item shows again
