good nigths i been working in a custom door from 3x3 size and alredy have it but it has some issues

 

 

an as the morphy's law dictates the day of the demostration it fails in this case it works,

one of the troubles is than normally zombies can pass the door after a little effort,  but this time only one little zombies goes througth the closes door

 

this door i made feels innecesary complex there is a control block in the center that open an closes the door two size door blocks draw left and rigth door

and i made an invisible block to block the pass  filling the empty space around the control center block but still mob get througth the door soo really is not working, and entityRayTrace methods  sees througth the door soo mi mobs atack like there where not i door at all, soo this is  not a fully solid block soo all this week work is wortless

 

i wanna make it simple i wanna make this door only one center block and this block must has a  CollisionBoundingBox as big as an 3x3x3 area

entityRayTrace must be unabble to see througth this block, and mobs must not be able to pase througth when the door is close

 

i read i can extend the block CollisionBoundingBox but the guide is for 1.6 and some methods are not anymore in 1.8 ore has diferent names

as i try it seems not posible to extends bounding far than 1M block so there must be trick

http://www.minecraftforge.net/forum/index.php?topic=9982.0

 

####

someone could tell me how to make a big collision bounding for this  door block in 1.8

 

sorry for the long explanation english is not native lnguague

 

 

 

 

 

You are going about it the wrong way. A Block in Minecraft can only be (or SHOULD only be) 1x1x1 maximum size, so if you want a larger structure, you need more blocks - that's why vanilla doors are actually TWO blocks, not one.

 

In your case, you need to coordinate the placing and removal of 9 blocks.

yap

i think it could be posible coze in the block json you can make models up to 3x3x3,    actualy this door is  the centerBlock + leftDoorBlock +RigthDoorBlock + 6X  aireSolido00 blocks fillng the space 

the  trouble is  some how mobs get througth the close door, i think coulbe solveit playing whith the bounding boxes from the blocks

 

 

### is some how some way to repeel or avoid the mobs to get trhougth the close door ??  but simple  not entityes nor whitchcrafts

 

 

all of the door blocks use this same  setBlockBoundsBasedOnState(IBlockAccess worldIn, BlockPos pos)  values

the only pasable is the center Block

You're already trying to do a hacky solution by making 'impassable air' - why insist on doing it both the hard and wrong way, when it is much easier to simply make real blocks at the positions you want to be real blocks?

 

Sorry, but making a single Block bigger than 1x1x1, in the context of Minecraft, is a terrible idea. The entire Minecraft code is built around the idea that Blocks take up at most a 1x1x1 cube and that within that cube will only be 1 block - messing with that is just asking for trouble.

 

You can make multi-block structures such as a 3x3 door, however, by placing and breaking all the blocks together, as I already mentioned. Vanilla doors and beds already do this - you just need to extend the concept to encompass a slightly larger scale.

 

 

if ound something contradictory ut still could make it work

 

in the BlockFenceGate they are declaring bounding from 1.5 high but this king of bounding is not visible so not know if it is working or not

 

 

  public AxisAlignedBB getCollisionBoundingBox(World worldIn, BlockPos pos, IBlockState state)

    {

        if (((Boolean)state.getValue(OPEN)).booleanValue())

        {

            return null;

        }

        else

        {

            EnumFacing.Axis axis = ((EnumFacing)state.getValue(FACING)).getAxis();

            return axis == EnumFacing.Axis.Z ? new AxisAlignedBB((double)pos.getX(), (double)pos.getY(), (double)((float)pos.getZ() + 0.375F), (double)(pos.getX() + 1), (double)((float)pos.getY() + 1.5F), (double)((float)pos.getZ() + 0.625F)) : new AxisAlignedBB((double)((float)pos.getX() + 0.375F), (double)pos.getY(), (double)pos.getZ(), (double)((float)pos.getX() + 0.625F), (double)((float)pos.getY() + 1.5F), (double)(pos.getZ() + 1));

        }

    }

 

 

but could be just an error from the coder  let behind

 

 

You CAN make bounding boxes bigger than 1x1x1, but, in general, you should not. Fences make the collision bounding box taller than 1 block so that players and mobs cannot jump over them, but the fence, as a block, still restricts itself basically to the 1x1x1 cube, which is why you can place blocks on top of the fence and the top block is still only 1 meter rather than 1.5 meters from the ground.

but could be just an error from the coder  let behind

Heh. Imagine that.

 

#getCollisionBoundingBox is the box used to detect collisions with entities. This is the part Fences set to 1.5F.

 

#setBlockBoundsBasedOnState sets the block's 'hit box', i.e. the portion of the block that can be clicked, which is the part you see when hovering over the block with your mouse. For fences, this is still maxed out at 1.0F on the y-axis.
