# Shifted Blocks API documentation
|
|
|
|
Here's how you add a shifted block:
|
|
|
|
|
|
|
|
First, you always need a block which should be shifted. This block **must**
|
|
|
|
have at least one texture and it **should** be a full-sized cube. Make
|
|
|
|
sure this block is registered already.
|
|
|
|
|
|
|
|
Then, call `shifted_blocks.register_shifted_block`.
|
|
|
|
|
|
|
|
If for some reason you need some extra customization, you can try to use
|
|
|
|
`minetest.override_item` after the block has been registered. Try to avoid
|
|
|
|
this.
|
|
|
|
|
|
|
|
## `shifted_blocks.register_shifted_block(itemstring, original_block, description, side_texture, help, block_texture, no_craft)`
|
|
|
|
Registers a shifted block variant of an existing block (which must be
|
|
|
|
registered *before* this function is called.
|
|
|
|
|
|
|
|
The texture on 4 sides will be shifted by a half block length. Two sides will
|
|
|
|
be the “cross-section” of the block so the block has a phyically consistent
|
|
|
|
look.
|
|
|
|
|
|
|
|
This also registers two crafting recipes of this shape
|
|
|
|
(unless `no_craft==true`):
|

|
|
|
|
|
|
|
|
* If `X` is the original block: Yields 2 shifted blocks.
|
|
|
|
* If `X` is the shifted block: Yields 2 original blocks.
|

|

|
|
### Parameters
|
|
|
|
|
|
|
|
* `itemstring`: Itemstring of the shifted block to register
|
|
|
|
* `original_block`: Itemstring of the original (unshifted) block
|
|
|
|
* `description`: Description of the shifted block. Recommended style:
|
|
|
|
“Shifted `<name of original block>`”.
|
|
|
|
* `side_texture`: Optional. If set, this is used as the texture of the
|
|
|
|
“open” side of the shifted block. It is recommended to make it look
|
|
|
|
like a cross-section of the block.
|
|
|
|
Default: Same as the 1st texture of the original block
|
|
|
|
* `help`: Optional. If set, add a custom help text for this block
|
|
|
|
(for `doc_items`). You normally don't need this, there is a sane default.
|
|
|
|
* `block_texture`: Optional. If set, this is the texture which should be
|
|
|
|
“shifted”. Only set this if it really differs from the original.
|
|
|
|
Default: 1st texture of the original block.
|
|
|
|
* `no_craft`: Optional. If `true`, no crafting recipes are registered.
|
|
|
|
Default: `false`

|
|
Default: Rotation is restricted to 3 axes
