Help Understanding Opening and closing door.

[wannabeuk]

Hey guys,

 

I'm having serious issues wrapping my head around the opening and closing of a door, i do not understand bitwise programming.

What i'm looking to do, is separate the standard onBlockActivated of BlockDoor into a function that will only open a door and another that will only close it.

Rather than the standard open/close toggle. However its been a long week of searching and im not closer to understanding.

 

Could anyone help me out?

 

Cheers

Ok, so since people dont seem to be able to answer, perhaps my question wasn't clear enough.

 

I have made some headway but i still suffer from a lack of understanding, I have the following two functions.

now this works on some orientations however on others it simple moves the hidge to the opposite side, at which point open and close happen the wrong way around.

 

Could anyone clear this up for me? what part of understand am i missing

 

private void CloseDoor(World world, int x, int y, int z, BlockDoor door)
    {
    			MinecraftServer.getServer().getConfigurationManager().func_92027_k(String.format("[%s] %s", new Object[] {"SERVER", "Closing Door:"}));
    		   //Open or close the door (opens if closed, closes if open)	
    			int direction = door.getFullMetadata(world, x, y, z);
    			MinecraftServer.getServer().getConfigurationManager().func_92027_k(String.format("[%s] %s", new Object[] {"SERVER", "Metadata = " + direction}));
    			int state = 6;
    	       // int var11 = direction & 7;
    	        //var11 ^= 4;
    			//direction ^= 4;
    			if(direction == 4 || direction == 12)
    			{
    				state = 0;
    			} 
    			else if (direction == 5 || direction == 13)
    			{
    				state = 1;
    			} 
    			else if (direction == 6 || direction == 14)
    			{
    				state = 2;
    			} 
    			else if (direction == 7 || direction == 15)
    			{
    				state = 3;
    			}
