Need help with always checking if a block next to a block has a boolean

[jamesc554544]

Need help with always checking if a block next to a block has a boolean that is equal to true. In my example i have some wire that i want to send power when it is placed it does this fine but after that the generator no longer sends power..., look at my github for the code

Use this if your boolean won't change ever (always true) for instance if you are checking for a Specific Block type.

try {
return ((YourBlockClass)Block.blocksList[world.getBlockId(x, y, z)]).yourBoolean;
}catch{Exception e}
return false;
}

 

Or this when it changes (You need a TileEntity for that)

try {
return ((YourTileEntityClass)world.getBlockTileEntity(x, y, z)).yourBoolean;
}catch{Exception e}
return null;
}

Uh.

 

You know there's only one instance of each block class, yes?  This is not how you store per-block information.

Uh.

I forgot about that...

I am using a superclass extending Block.class which holds this specific variable to let my pipes connect to other pipes and a subclass for the different blocks

 

I guess it will work like this:

public class BlockPipes extends Block {
        public boolean isPipe = true;
        //More stuff?
}

public class SpecificPipe extends BlockPipes {
       //The BLOCK

}

try {
return ((BlockPipes)Block.blocksList[world.getBlockId(x, y, z)]).isPipe;
}catch{Exception e}
return false;
}

....

if(Block.blocksList[world.getBlockId(x, y, z)] instanceof BlockPipes) {

}

 

Now you don't need the variable, or the try/catch (which is SLOW).

Oh I've never thought about that Thanks
