Hi

Why not just use the existing door?

i.e. what do you want to do differently?

Door is a bit complicated because it needs its own renderer and it's made up of two blocks not one. It's also got a pile of logic related to opening & closing, whether entities can pass through it or not, changes to the bounding box, etc.

If you want to tweak something simple, like the sound it makes when it opens, then it's easy. Otherwise it's going to take a fair bit of skill and knowledge about the vanilla door and renderers in particular.

I want to create a new door. with the material of rock, my own texture, name, and id. Doesn't it use the texture-map?

Hi

In that case, I think you're in luck. I'd suggest

create your

class BlockMyNewDoor extends BlockDoor

add a constructor

add icon member variables (copy the ones from BlockDoor)

override

public void registerIcons(IconRegister par1IconRegister)

to register your new icons/textures into BlockMyNewDoor member variables (the BlockDoor ones are private unfortunately)

and override

public Icon getBlockTexture(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)

copy the code from BlockDoor.getBlockTexture into BlockMyNewDoor.getBlockTexture and change the references to the icon fields to your own icon texture member variables.

The material is in the constructor so it's relatively easy - and if you want your stone door to act like a wooden door (i.e. players can open it) then you probably don't need to change onBlockActivated either.

Thanks Man, Figured It Out Here's The Code For Those Who Are Struggling With This

Main Class

//Making The Door And Item
public final static Block AdobeDoor = new AdobeDoor(900, Material.rock)
		.setHardness(2.0F).setResistance(10.0F)
		.setStepSound(Block.soundStoneFootstep)
		.setUnlocalizedName("adobe_door");
public final static Item AdobeDoorItem = new AdobeDoorItem(901, AdobeDoor)
		.setUnlocalizedName("adobe_door_icon");
//Registering The Door And Items
LanguageRegistry.addName(AdobeDoorItem, "Adobe Door");
GameRegistry.registerBlock(AdobeDoor, "AdobeDoor");
